In each of the above clauses the word “accessible” is used and is a requirement in order for the installation to be compliant with the standards.

Locating a gas appliance isolation valve on the top of an appliance does not enable the quick isolation of the gas supply as required by AS 3814 clause 2.9.8.3. In order to achieve compliance the gas appliance isolation valve will be required to be brought down to low level adjacent to the appliance and be clearly identified.

An alternative means of safe access acceptable to Energy Safe Victoria may be provided by the property owner or his representative by agreement.

A Pressure Reducing Valve, or commonly a PRV, is a device placed inline from your water source (tap or pump) to reduce or regulate the pressure of the running water. This is to protect lower density pipework (LDPE only has a maximum pressure rating of 300kPa) and provide consistency to drip line emitters and sprinkler or spray heads.

(a) the location of appliance isolation valves and consumer piping regulators; and(b) the relevant requirements of AS/NZS 5601.1 and AS 3814.

Permanent fixed means of access should be installed where the regulator is located on a roof or at a height beyond the extent of normal steps or ladder. Fixed access is to comply with AS 1657-2013 Fixed platforms, walkways, stairways and ladders – Design construction and installation.

In many instances burners are located on top of an appliance. This may be for a number of reasons, such as the location of oven re-circulation fan and combustion chamber for compactness or floor space limitations. Spray and bake booths are a common example.

All commercial / industrial installations require a means of isolation provided on the inlet connection of an appliance.
