Welcome everyone to this joint esv and vba webinar series
the webinar is to provide technical guidance to all practitioners and manufacturers on achieving compliance to
gas fitting installations the esv vba representative speakers for tonight's
webinar are from esv david crew and myself in zolfin city
and from the vba john lowman as we continue through the presentation
there is a q&a tab function allowing everyone to ask questions at the end of the presentation
the esv vba panelists will be answering some common chat box questions and this will obviously depend on the
finish time vba and esv will also collate a set of frequently asked questions and post these on the vba and esv websites
Agenda
so tonight the webinar agenda will cover some major changes to the new leisure lpg cylinder valves leisure cylinders
between four and a half kg and nine kg the new type 27 valve
which is the subject of amendment 4 of asn s5601 part 1 and
is also replicated in the revision of asn s5601 part 2. this first part will take
up to 15 minutes and is particularly aimed at general gas fitters and industry
part 2 of the webinar will follow which will focus on the update of the new published document asn 0s 560
part 2 2020 lp gas installations in caravans and boats for non-propulsive
purposes so part 2 is relevant for practitioners working in the caravan or boating
industry gas fitters not working in this area a work are welcome to stay on
for the presentation or if you choose so you can you can log off
so esv is victoria's technical and safety regulator for electricity gas and pipelines its role
is to ensure the victorian gas and electricity industries are safe and meet community expectations
esv is also responsible for licensing and registering electricians and educating the community
about energy safety it also has responsibility for overseeing the regulation of complex gas
installations and type b appliances including gas installations in boats and capitaling vehicles
Victorian Building Authority
the victorian building authority regulates building and plbing practitioners to ensure the achievement
of efficient and competitive building and plumbing industries in victoria
their functions include registering licensing and disciplining disciplining plumbers in victoria
providing technical advice and informed solutions to industry and inspecting investigating and
auditing practitioners and work sites to enforce compliance with the relevant
legislation its role also includes the regulation of standard gas installations
otherwise known as type a installations
Type 27 LP Cylinder Valve
we'll now discuss the new type 27 lp cylinder valve also known as the lcc 27.
Amendment 5601 Part 1
so on the first of october this year standards australia published amendment 4 to os nzs 5601 part 1.
the amendment introduces new requirements relating to quick connect devices aimed at reducing
the risk of gas leakage from lpg cylinders of 10 kilograms or less for improved conumser safety
the cylinder quick connect devices are also replicated in asn's at s5601 part
2 2020.
the following slides will therefore apply for both 5601 part 1 and asn s5601 part 2.
the new type 27 valve the new cylinder valve will be known as the leisure cylinder connection type 27
valve or lccc 27
these new valves will not allow gas to flow when the valve is open unless the gas connection is made and will reduce the risk of potential gas
leakage and gas safety incidents
[Music]
The project objectives are to replace the existing type 21 pol cylinder valve with a new sofa lpg cylinder valve
the lcc27 to reduce serious incidents that include misuse and leaking connections the change
applies to small portable lpg cylinders only so that includes four
and a half kilogram and nine kilogram leisure cylinders
[Music]
the new connection has multiple safety features that reduces the risk of leaks and serious fires both in use and during transport.
the project was formally started in october 2018 however involved years of preparation
with stakeholders behind the scenes to assess the risk and investigate options.
the type 27 connection is specified and referenced in eight standards across five committees and required
extensive consultation committees
Animation
so we have a short animation to show you in relation to the new valve and how at
the moment the type 21 the type 27 coexist we'd like to thank manchester tanks for
allowing us to use their animation videos please note that the animation shows the
use of a hose clamp which is not acceptable under australian regulations.
the first animation shows the type 27 connection to the new type 27 valve
the type 27 connector cylinder quick connect device incorporates a thermal protection which
allows for isolation of the gas supply in the event of the fire and you can see there that gas will only
flow when the connection is made once the connection is disconnected
the spring-loaded back check valve then shuts off the gas supply
so the following animation shows how the older or current type 21 pol fitting will
coexist with the new type 27 valve so the new valve actually has a left
hand internal thread that will take the current type 21 pol so what this means is that existing
barbecues patio heaters and pigtails will still be able to be connected to
the new valve. you'll note that the the new valve also has a coarse external thread which is a
right hand thread which obviously the connector that was shown in the previous animation would connect to.
again the principle is the same even when you're using the type 21 pol when that is disconnected the
spring-loaded back check valve shuts off the gas supply
so amendment 4 to asn's at s5601 part 1 includes a transition period for the
valves on the cylinder outlet side so under the transition period
the current type 21 pol valve which you can see there on your left can continue to be used up until the 30th of september next year.
from the 1st of october 2021 the type 21 valves can no longer be used on new and re-tested cylinders
this equates to a 12-month transition period. the new type 27 valves will be permitted for use from the 1st of april next
year therefore between the 1st of april and the 1st of october 2021
there is a 6 month overlap period where both types of cylinder valves can be used on new
and re-tested cylinders.
the key point to remember is that from the 1st of october next year you can only use the type 27 valve on new and re-tested
cylinders and the really important point to make here and we've had lots of questions about this is what happens to my existing cylinder?
do i have to have the valve changed on that and the answer to that question is no you don't.
the the trigger for changing the valve on existing cylinders is the expiry date on the collar of the
cylinder so each lpg cylinder has an expiry date stamped on the collar of the cylinder, so what happens with cylinders at the moment is that if that expiry date has not elapsed the cylinder goes back to a refilling station where the cylinder
will be refilled before it's put back out into service.
however the 9 kg cylinders in particular or the leisure cylinders in particular have a 10 year retest cycle, so what that means is that date stamp on the collar of the cylinder if that date has elapsed when that cylinder goes back to the local swap and go rather than the cylinder being refilled. what happens to that cylinder is that it
goes to a gas cylinder test station where the old type 21 pol valve is removed the cylinder is pressure tested and the new type 27 cylinder valve will be will be fitted to the re-tested cylinder before it's put back into service, so the reality is on existing cylinders theoretically there is going to be a 10-year period because of the 10-year expiry date on cylinders in terms of the transition, i'd like to think that it'll probably happen sooner than that through market forces but i guess we'll wait and see but i guess it is a transition that will take some time to occur, so there is a slightly longer transition period available for the appliance connector.
the type 21 pol appliance connector can continue to be used until the 31st of march 2022. from the 1st of april 2022 it is proposed as part of a future amendment that they can no longer be used so this represents an 18-month transition period, so the new type 27 appliance connector referred in as ends at s5601 as a quick connect device can be used from the 1st of october next year, therefore there is a also a six month overlap period between the two types of appliance
connections. so the key message is that the type one appliance connectors manufactured after the first of april 2022 can no longer be used but there will be
a six-month period as i mentioned just a moment ago from the first of october next year until the 1st of april 2022 where appliance manufacturers can manufacture their barbecues and patio heaters with either connection
Standards Alert
so the vba and esv have put together a summary of the key changes relating to this amendment in the form of a
standards alert. this is available for free download on both the vba and esv websites in addition to the recent amendment 4
to part 1 of asn's s5601. there is currently separate work underway by standards australia to revise the whole standard.
it is expected that a draft of this standard will be released for public comment by the end of the year.
so that concludes the first part of this presentation on the changes to quick connect
valves. i'll now hand over to tin tran from the vba who will open up the question and answer
part of this webinar.
thanks enzo thanks very much for taking us through those changes
so we now have some time to for questions and answers so i'd like to invite you all to ask
questions using the q&a feature of zoom which is located on the bottom of
your screen there. we have one question already that's Why are we making this change
this question relates to probably the rationale for these changes, is how
many fires etc were found to be caused by the old pol fittings yeah
so one of the questions that we we've been asked during the webinar series is why are we making this change
and there's a simple answer to that it's all about safety. energy safe victoria some time ago a few years ago
actually looked at its incident data and what it noted in particular was that during the the summer months
in particular that we were seeing a lot of incidents and injuries occurring around barbecues,
and barbecue use. and when we drill down into that data further what we found was that the vast majority of the injuries
were not caused so much by the barbecue itself but by leaking gas at the cylinder
connection, so this is where a consumer might think that they've done up their cylinder - their pol fitting
up tight and and it's not the case, and there's been gas that's been leaking which would then
ignite from from, you know, the ignition sources on the barbecue.
we've also had you know incidents that have occurred because of o-rings in pol fittings that
have dropped out or even worse the rubber bull nosing has either cracked or completely gone missing.
we've had incidents of of that nature so it was quite clear to energy safe victoria that there was a problem here so we
actually confronted the the industry body gas energy australia on this issue and and suggested that something needed to be done about it
so the type 27 valve is the outcome of those discussions the other thing that we took into consideration was
that there was unfortunately a fatality about two two years ago i think. some of you may have seen this on the
on the news because it certainly was splashed across the media. there was video of a removalist truck driving through an
intersection that blew apart and that was found to be the coronial inquest into that fatality found that the cause was gas
leaking from a 9 kg cylinder that was being transported in the back of that that van so that unfortunately resulted
in a fatality to the the driver of that vehicle so that reinforced the need for us to do
something about this
thanks enzo. next question relates
Is this a national adoption to whether other states and territories are also adopting these same transition dates
and i guess part of implicit in that is also whether states and territories also adopting the same requirements as well.
is that a national adoption as well? yes it is so this is a national approach so every state and territory in australia will
be adopting the new valve for leisure cylinders - so absolutely it is a national approach and it couldn't work to be honest it
couldn't work any other way, given that you know cylinders can be transported around and essentially have no borders when you think about it. the the gas technical regulators and the gas technical regulators committee was quite adamant to to force this
change on a national level and for the benefit of those that have tuned in tonight, you can google the gas technical regulators committee, or the gtrc, which has its own website. if you go to that website and you click on the publications tab you will find a technical guidance
bulletin that has all the information that's been presented tonight around the transition time frames for this change.
Why dont we just introduce a specific date?
at the moment with the different dates for the cylinders and the appliance regulators it could be confusing - yep so it's a good question
so when we had a look at making this change and we consulted with other gas technical regulators and the industry body gas energy australia we took into consideration the fact that this transition process had to be done in a number of stages
so we first of all had to consider that the manufacturers of the new valve needed to be given time to actually manufacture and be able to supply the new valve, and there was no certainty around this project until such time as all the relevant australian standards
were updated to make this happen so that actually happened on the 1st of october this year.
once all the relevant standards were published there was certainty in the market that this was going to happen
so essentially there's a six month period between the first of october this year and the first of april next year
where the new valve will not appear, and the purpose of that time frame is to give the manufacturers time to manufacture and supply the valve and also to give other stakeholders in particular the refilling stations the time to set up their equipment so
that they can adapt to the new valve - so that was the reason for the six month wait on the introduction of the valve
in relation to the introduction of the appliance connection there's a further six month wait on that and of course with that that transition
period the reason for that is that we want to allow a bit of time for the new valve to start to filter into the
market before we start to see the new connector come in
so the idea is that we have a period of time from the first of april next year when the new valve will start to appear until essentially the first of april 2022 when it becomes mandatory for the new connection to come on or be fitted on to the hose assemblies so essentially it allows enough time for the new valve to filter into the market before we start to see the new connections come into the market because obviously the last thing we want to do is introduce the new appliance connection if there aren't enough cylinders out there that have got the new valve
Will these changes make their way to larger LPG bottles?
okay and the next question i guess relates to whether these changes will eventually make its way to larger
size lpg bottles and the example given was uh i guess people living in areas with no main stores where those larger bottles like the 45 kg ones are common, yep so the answer is no the this change won't occur on the larger 45 kg cylinders. there are two reasons for that uh one is that the data the incident data doesn't suggest that uh there there's an issue there with the 45 kg cylinders unlike what we saw with the
9kg cylinders and also we take into consideration that the 45 kg cylinders are typically replaced when they're empty by uh trained
individuals so typically they're people that work for the lpg gas companies that that come
around and take the empty cylinder from your home uh and when that happens they they obviously you know replace it with a
full cylinder and they're typically using a spanner to make up the pol connection so you know they're people that have
been trained and know what they're doing so the risk is much much less in terms of safety
and secondly with the new valve obviously with it having a back check valve incorporated within it
there is a slight restriction on the flow compared to the current valve which has no back check valve and so the concern there was
that if we introduced this new valve into the larger cylinders that there could be some applications
in particular appliances that might consume a significant amount of gas uh that potentially there was a potential there for gas flow to be limited on those appliances and we certainly didn't want that to happen so they were the two main reasons why you know we're not
carrying this change through to the 45 kg cylinders okay and the next one again on the 20.
Will the new 27 type valve leak?
on the new 27 type valves question was if it's not done up tightly whether it will leak compared to you know which is compared to the current type 21 valves yep so uh all the data that we've seen today and the experience we've seen in other parts of the world with this type of valve would suggest that if the connection is not done up tightly that you won't get any gas flow, so that's the main idea behind this valve.
i should point out that this particular type of design has been around for many many years in the usa so at
least the last 25 years they've been using this type of valve in the usa and in new zealand they've been using
this type of valve for the last decade so there's there's a fair amount of history there that gives us a lot of confidence that it's going to be able to do the job
thanks enzo next one is could there have been a valve developed with a bayonet connection?
yes that that's another possibility that we could have looked at - it's a similar principle to bayonet connection but i think the
benefit of this valve is the fact that it has the internal left-hand thread which means it doesn't inconvenience
existing owners or owners of existing barbecues and patio heaters, or even for that matter existing gas installations in caravans and boats that will have pigtails with pol fittings.
so i think the the benefit of having this valve apart from the fact that you know that there's a track record there with its use in the usa in new zealand is that you know the the the fact that it's backward compatible with the current type 21 pol
Will this requirement apply to the general public?
i guess whether this requirement this uh will apply to the general public and also more broadly as well if you could also provide some advice on
how consumers would be advised of these changes as well yeah absolutely
the gas technical regulators committee along with the industry body gas energy australia are looking at communication to be put out to all stakeholders including the the general public in relation to this change so there's a working group that's been set up that is looking at
those means of communication and that will include things such as social media uh websites and other means of communicating the news to the to the consumers and and i guess this is again that it it highlights the the reason why we have this six month window where nothing actually happens in terms of the the change to the valve and that is to allow time for us to also educate the public on this change so that will be happening over the course of the next six months
Life cycle and maintenance
thanks enzo uh next one is whether you have any information around the life cycle and maintenance of these valves
uh that's a really good question actually, I don't know too much about the life cycle of these valves it's something that obviously we can we can look into and and and look at the experience in the usa and you and our our cousins over the ditch in new zealand in particular they'll be able to provide us some some information on that, but in terms of maintenance - look there's a couple of things that obviously have to be taken into consideration obviously the threads so both the internal left hand thread and the external right hand thread obviously when looking at
one of these valves i just have to make sure that the threads are in good condition just like you would at the moment on an
existing type 21 pol so you don't want any cross threading or anything like that occurring and the other important thing to consider on this new valve is when you look inside the valve uh you will see that there's a rubber seat and so the the condition of that rubber seat
has to be inspected from time to time so basically the the threads and the rubber seat inside the valve are the uh the components that have to be maintained
Vandalproof
uh so next one relates to also whether these new valves are whether they're vandal-proof and also whether any of the parts could be removed ah
look i dare not say that they're vandal-proof, i guess if anyone really wanted to try and vandalize something they could always find the way but what i can say is that this valve is certainly a lot safer than the current type 21 pol from the point of view that you know we've even had incidents where people have wanted to commit self-harm using a 9kg cylinder and that's not to say that they can't do that with this type of valve it's just that it makes it a little bit more difficult for them to do that if they wanted to harm themselves because they'd have to actually connect something to the cylinder for the gas to flow, so you i guess one could never say never, but certainly it certainly would
reduce the risk of those sorts of things from happening and the other thing i guess that needs to be taken into consideration is that with this new valve there's a couple of additional safety features that perhaps you know the valves that are used in the usa in new zealand don't have an example of that is the bleed nut for when you're decanting. so one of the things that was identified with the current type 21 pol valve is that they had instances where the bleed nut could actually if it was unscrewed too much it could actually drop out so we now have a captive bleed nut so you can unscrew it as much as you like but the screw won't won't fall out so you know we've taken that and also i mentioned
before about a thermal fuse in the in the connector in the event of a fire which will disconnect the the the gas so there's a couple of
additional safety features that come with this valve
thanks enzo so i'm conscious of the time it's already 6.30 and we still have obviously quite a lot of questions but i think we need to move on to the next uh part of the presentation otherwise we'll won't finish in time but i'll just select the i guess
everyone on the line know that we'll try and answer some of these questions as well through the messaging function as we
continue with tonight's presentation and also as a reminder that you know we'll be posting a lot of these kind of
frequently asked questions on both vba and esv's websites as well so if we don't get a chance to answer some of your questions hopefully we'll be able to have that posted on our websites at a later stage as well.
so that concludes the first part of tonight's presentation. the next part
as as enzo mentioned before is going to be focus on as nzs 561 part two so that presentation
is going to be relevant for practitioners working in the caravan and boating industry
so gas fitters could log off if they're in if they if they want to but we would also encourage those that
are interested to stay for the remainder of their presentation as well
i'll now hand over to john lowman from the detroit building authority anya
thanks tim and thanks enzo so good evening everyone the second after presentation focuses on gas fitting work
in both caravan and boating industry and is specific to the new requirements of australian new zealand standard 5601
part 2 2020.
so this is a completely new revision of the previous 2013 edition of the standard
the project started in july 2016 and finished in august 2020 so there's a lot of work behind the scenes involved over the four year period regarding the outcome of this document the document was published on the first of october this year and there were two rounds of public comment with 126 public comments received for the committee to consider
Timeline
transition arrangements for the new australian new zealand standard 5601 part 2 2020. so as mentioned before this
standard was published on the 1st of october 2020. the timeline on the screen clarifies at
what stage the appropriate standard will apply to the both caravan and boating industry
vba and esv is providing a six month transition period to allow industry to adjust to the new
changes before the new edition of 5601 part 2 2020 requirements are enforced,
so that means between now and up to the end of 31st of march 2021 the 2013 version
of 561 part 2 shall be used so this is highlighted on the top left-hand
tick green tick on the screen then from the 1st of april 2021
the 2020 version of 5601 part 2 will be the mandatory document so that
notes the six month transition time frame that it doesn't apply to the requirements
relating to the cylinder quick connect device, where there is a 12 month transition time frame applies as pre we discussed
in the early part of this presentation, so if we look on the screen we can see at the top left hand corner it relates
to the 2013 version of this of the current standard we use now, and it's up to the 31st of march 2021.
when this document will be up to that you can use it then
if you look in the center of the screen you can see the green tick that from the 1st of april 2021 that's
when the new 2020 version of the 561 standard part 2 will be used
now that first of april 2021 does not include the quick cylinder quick connect device so that
comes into effect from the first of october 2021 it's indicated in the bottom right hand
side of the screen
New definitions
there have been a nber of new definitions included into the revised standard some of these you can see on the screen now.
so if we look at the screen we see controlled area so this will be clarified further within the
presentation The caravan domestic so there's two definitions of caravan within the
document so caravan itself which is the intent for living but also to be used as a workplace,
and then we have caravan domestic which can only be used for living and not as a workplace.
also we see encapsulation and ignition sources so they'll be elaborated
further on through the webinar non-sparking by nature. so these are devices such as plugs fixed
terminal or encapsulated solenoid so these are devices that do not have any electrical contacts
that move uh quick connect cylinder device so as just mentioned and toughened safety glass so we'll go through a little more of these details
during this presentation
prohibition of in-situ cylinders on caravans
so in situ cylinders so these are cylinders where the truck pulls up and now runs out of hose and then fills them fills the cylinder up
add on site. so typical some similar way there's no gas transition pipeline so it might be something like a
farm or sap farm or something like that so these now these types of cylinders will be prohibited for use in caravans
in situ cylinders they're also prohibited for use in boats unless it is specific specifically
approved by the relevant gas technical regulator, and as we all know the relevant gas technical regulator for victoria is
energy safe victoria, so gas fitters requiring to install one of these on a boat would need to
submit their application to energy safe victoria and ensure that the installation is approved by energy
safe victoria prior to you using it.
new recommendation for the orientation of cylinders
so a new recommendation has been included in relation to the orientation of cylinders that has been installed on the drawbar of a caravan so cause 1.3 3.1.4 recommends that the cylinder relief vent be positioned at a 45 degree angle
away from the caravan, so this allows for the discharge of the relief valve into the clean air
as you can see in the diagram on the screen the main reason why this could could not be mandated is because
the the cylinder has no sort of locking or mechanism devices to ensure that it's locked in at a 45 degree angle so be pretty hard
to mandate the gas fitter to install the cylinders on the caravan when the caravan is sold and the
conumser or the property owner takes purchase of that caravan that when he goes to exchange
exchange these cylinders that he would be putting them back in these positions, so it's more like making the conumser
aware either the caravan company or the gas fitter to ensure if that relief vent is is
requiring to discharge for any safety reason that the cylinder should be positioned and that 45 degree angle in the safe
clear area
Caravan clearances
new clearances on a caravan drawbar around ignition sources so this is relating to your control area or a controlled zone so there's a bit of new figure added to the standard and it shows the clearances that are now required around the installation of an ignition source on the drawbar of a caravan
so this figure it makes it easy to determine where the cylinder can be positioned relevant to the ignition source
the figure on the screen, it shows some variable heights and these are determined by the height of the cylinder and the length of the
drawbar. if we look at the cylinder on the screen we can see some wording associated with that cylinder and it relates to varies
and the reason why it's very speed is because the length the caravan comes in different sizes so whether it's a
single axle it might be a double or a triple axle. when these caravans have longer sizes the actual drawbar itself
becomes longer so therefore they cannot be as prescriptive measurement associated on these. on the screen that you can see now also the cylinder positioning or locating of that cylinder on the drawbar. also the drawbar comes into effect too because the height of the drawbar
or the positioning of then cylinders on the drawer bar itself so that also varies that type of measurement as well.
something you need to consider is the length of the caravan the drawbar relating to the positioning of them cylinders you'll also notice that the measurements are taken from the center of the cylinder so they're in a cone shape and they go down to the draw bar and then drop down
to the ground level
domestic caravans are defined term as i just mentioned so clause 1.3.8 defines domestic caravans it's caravans with no more than two lp cylinders with a maximum capacity of 10 kilograms each.
clause 1.3.41 it defines an ignition source so examples of ignition sources are some such as a generator a battery or an outdoor power point and as we all know as part of the operation of a caravan we require or vicroads require safety road safety equipment, so these are such as your breakaway plugs or anderson plugs so these are permitted on the drawbar of the caravan. just to clarify electrical devices that are non-sparking by nature or encapsulated are not considered ignition sources in a controlled area
Drain requirements
diagram showing drain requirements for cylinder compartments in a compartment so if if the gas fit or the caravan company is installing a cylinder in a compartment you need to ensure that the drain from the compartment determines terminates a minimum of 1500 millimeter away from an ignition source unless the ignition source is at least 500 mm above the drain outlet it's indicated on the screen so if we look at
the screen we can see the cylinder. we see the drain coming from the base of the compartment and then we see the path of vapor if we have a let's say it's a ignition source 500 ml above that vapor or that drain pipe well then that'll be outside the exclusion zone.
once it's inside that 500 mil well then you need to have that 1500 ml clearance
Encapsulation requirements
new requirements for shutoff solenoid valves to be encapsulated in a gas cylinder compartment
so compartments with lp cylinders must now not contain any equipment other than the gas safety shadow valve
this must be of the encapsulated type so this requirement it applies to both boats and caravans encapsulation it can be confirmed by the
reference to the relevant manufacturer's installation instructions or the specification sheet. the device on the screen is only example only, so therefore should not be considered an encapsulated device
encapsulation requirements defined under clause 5.3 for electrical devices which are be fully sealed in the flame retardant polymer provide a minimum ip55 protection rating have no exposed terminals such as be pre-fitted with flying leads or be terminated via mating connection
enclosure and cable gland and also contain no moving electrical contacts
Cylinder compartment requirements - clarification of access to internal cylinder compartments in a caravan
so the requirements for internal cylinder compartments have been made it clearer under clause 3.3.4.1 and must meet the following requirements
the cylinder compartment it must be designed to contain no more than two 10 kg cylinders. as i indicated before, even though it's a camper it's a living space it's classified under caravan domestic so therefore it indicates that no more than two 10 kg cylinders must be sealed to prevent the flow of vapor into the caravan or camper
when the cylinder compartment door is closed the door opening edge is no more no less than 50 mil above the compartment floor so that's not less than 50mm above the compartment or be drained in accordance with clause 3.3.1 f which is your compartment drainage area of your drain 500 millimeter squared or your 5000 millimeter upper and lower ventilation requirements
access to any internal cylinder compartment requires that the caravan access door be open such that the operator is outside the caravan so this is a highly change within the standard it actually clarifies that the operator of the caravan must be outside that caravan he can't be inside to exchange that cylinder he must be standing outside the caravan to exchange that cylinder within
something else i want to highlight too we had a couple questions relating to the camper or uv and the question was relating to
exhausts so would the exhaust on the caravan or the camper be considered an ignition source so as we all know petrol and diesels, they do have or they could backfire so in their scenarios they would be classified as an ignition source so therefore you need that 1500 ml
clearance to the to the drain or that arm ventilation within that compartment
Range hood clearance
minimum clearances distance between the cooktop and the range hood have now changed to 650 millimeter so originally this was measured from the highest part of the burner now the clearance has been taken from the pan support or the gas appliance so this this clearance it does not apply if the appliance has been certified for a closer installation so when you you're installing an appliance within the caravan, and let's say you you want to have it a lesser clearance than 650 millimeter you need to ensure that that appliance that you have is actually approved by energy safe victoria or it's been certified similar to like aga
i have that certification to ensure that that appliance can be certified at a lesser clearance if you're unsure whether this is approved well then you need to contact energy safe victoria all other clearances they remain the same so this change brings australia in line with most other countries around the world and reflects the new technologies being used in the manufacturing process of some appliances
as we all know some of you may be working in the housing industry or even with the caravan and you're measuring from the opening up the range hood manufacturer specifications and the measurements come from the underside of the rainfield to the pen support or your the trivet of the gas appliance and as we all know our measurements were usually taken from the highest part of the burner so now this brings it in line with similar to other countries around the world and it reflects the new technologies being used in the manufacturing process
existing cookers installations
these can remain the same and minimum use 600 mil but again if the manufacturer's installation instructions and specify greater clearance that needs to be adhered to so if you're just changing an existing appliance in an existing caravan to a newer gas appliance well then you
and you want to install at 600 mil that's fine, but you need to ensure that the manufacturer's specifications are adhered to because if they specify a greater clearance well then you need to have that greater clearance applied to this installation,
so that concludes me for the at this time i'll hand it over to dave david crew from energy safe victoria and
he'll discuss the next section of this presentation
thanks john uh and enzo so moving on
there has now been an allowance for hard drawn copper pipe to be used on houseboats on inland waterways on the low pressure
side of the gas installation
clause 5.1.4.2 now allows the use of hard drawn copper for the use of vessels used on inland waters this is applicable as i said
for the low pressure side of the installation
after the first stage regulator all pipes shall have a pipe manufacturer applied and bonded coating but all other requirements remain the same
limitations of hose assembly pigtails to be of class f hose assembly pigtails are now required to be of the new class f type
this class has been introduced into as nzs 5601 part 2. they must meet the requirements set out in asns 1869 and these hoses have a maximum
pressure rating of 2.5 mpa or 2500 kpa
they also have a working temperature range of minus 20 to plus 100 degrees celsius and are required to have an excess flow valve installed in the cylinder connection fitting as you can see indicated on the screen there
the prohibition of the use of press fit connections clause 5.1.4.4 now specifically prohibits the use of press fit connections the photo on the screen shows the result of what happened to a press fit connection that was installed in a vehicle that was driven from melbourne to adelaide
and the fittings separated causing a gas leak due to vibrations and road conditions encountered on a long road journey over from melbourne now it's important to point out that this is not a new requirement, that this is a requirement that is made or been made clear in the new standard as far back as 1995
i have a copy of the of page 601 as it was known then and press fit fittings were still prohibited at that time so just to reiterate this is not a new requirement but a requirement that has been made clearer in the new standard
there are new requirements for carbon monoxide detectors in boats to conform with referenced international recognized standards so call 7.5 now states that effective unrestricted ventilation shall be provided to at least two openings fitted at opposite ends all sides of the cabin
or preferably to the decade or underside of the deck where the boat otherwise meets
these requirements of the clause but it isn't practical to use the boat without covering the permanent ventilation solution you know large seas and the like a carbon monoxide detector in conformance with en 50291 or ul 2034 capable of detecting low concentrations of co and having an audible alarm shall be installed
just a note on this we have noticed in the final published version of asn 0s5601 part 2 that there is a reference in this clause to en50291-1 it should actually be en50291-2, which is specific to boats this will be corrected in the first revision or sorry the first
amendment of this standard
there's been a new informative appendix appendix l included in the standard and this appendix helps with purging of small vole gas installations
and has been newly introduced as i said in asm z5601 part 2. the appendix contains tables with the approximate vole and pipe for
any given length there are some resources available on both the vba and esv website and we have put together what we call a standards alert relating to the revision of asnzs5601 part two
this goes through some of the common changes and this is available for a free download from the vba and esv website
so once again thank you all for attending tonight's webinar. we will be going through some some questions now these webinars uh will be available at the conclusion of these webinars on both the esv and vba website along with some common questions and also you'll be asked to fill in a short feedback form at the conclusion of tonight's webinar if you if you could possibly take the time to fill that out it gives us valuable information in regards to how we best present these series of seminars i suppose to you guys in the future so if you've got some time we'd love for you to fill it out and give us some feedback on
on what you would prefer moving forward so thanks again tonight for your attendance
