INSTALLATION
29
The water heater must be located to ensure that the location of the flue terminal
complies with the requirements of AS/NZS 5601.1. As a guide the following
requirements are extracted from the Gas Installations Standard. The distances
are measured along the wall behind the water heater.
• At least 500 mm between the flue
terminal and the edge of any
opening into the building, such as
an openable door or window,
measured horizontally* and
vertically.
• At least 500 mm between the flue
terminal and a return wall or
external corner, measured
horizontally*.
Note: * If these horizontal distances cannot be achieved, AS/NZS 5601.1 states
an equivalent horizontal distance measured diagonally from the nearest
discharge point of the flue terminal to the opening may be deemed to comply.
Check with the local regulator.
MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table below,
an approved pressure limiting valve is required and should be fitted as shown in
the cold water connection diagram on page 36.
