FOUNDATION
To ensure adequate ventilation, position unit on a timber support base on a
concrete slab.
(SEE FIGURE 5)
Alternative forms of water heater bases are acceptable providing they allow for
adequate ventilation.
Attention is drawn to the weight of the water heater when full and installer
should ensure that the base and footings are substantial enough to avoid
subsidence etc.
SAFE TRAY
It is a requirement of the National Plumbing Code AS/NZS 3500.4 that all water
heaters be installed in a safe tray, where in the event of a leak, property may
otherwise be damaged. Installation of safe trays must comply with clause 4.4 and
sub clause 1 to 5 of the abovementioned Code.
WATER PRESSURE
Test Incoming Water Pressure with a gauge. If pressure exceeds 1100kPa, an
approved pressure limiting valve is required and should be fitted as shown in the
installation diagram. (Page 9)
Pressure limiting valves are not supplied with Water Heaters.
TANK SUPPLY
Not recommended without a pressure pump, minimum supply pressure should
be no less than 350kPa.
A non-restricted HPNR valve may be required to be fitted for supply less than
350kPa.
