The protection of combustible surfaces when installing gas appliances is critical for achieving a safe gas installation. This can be achieved by installing the appliances with the clearances prescribed in AS/NZS 5601 or manufacturers installation instructions (whichever is the greater) or where these clearances can’t be achieved protecting the combustible surface.
Inadequate protection to the combustible surface can lead to a dangerous gas installation and in worst case scenario result in a fire. This can be avoided if the correct method of providing protection for combustible surfaces is implemented.
When Installing Fire Resistant Material
Where the means of compliance is to install fire resistant material, Energy Safe Victoria (ESV) requires a written confirmation from the manufacturer stating:
“The material complies with the requirements of AS/NZS 5601.1 Appendix C”.
The written confirmation must:
- Be on the board manufacturer’s or supplier’s letterhead.
- Identify the fire resistant material proprietary (brand) name.
- State the fire resistant material’s thickness.
- State the load bearing or non-load bearing nature of the board and is dated in the same year it is submitted to ESV.
In addition, a Combustible Surfaces Means to Comply Report will need to be provided. This will be issued when ESV set the conditions of acceptance following the review of a gas application.
ESV reminds Gasfitters that without the required information we cannot accept your gas installation.
