Installation
In accordance with AS/NZS 60335.2.21 the water heaters must be xed
to the ground using the attachment provided and in compliance with
the New Zealand Building Code Clause G12, Seismic restraint of storage
water heaters.
Installation must also comply to AS/NZS 3500.4.2 and all local codes.
The clearance required needs to be adequate for service/replacement
of cold water inlet piping devices, PTR valve and tempering valves
(where tted), elements and thermostats. This may be facilitated by
correct orientation of the cover positions when installing. There are no
operational clearance limitations to surrounding structure. PTR valve
removal requires approximately 150 mm for withdrawal.
Combustible Material
It is recommended to not place combustible material on or adjacent to the
water heater.
Hydraulic Connection
Before making the hydraulic connection, it is essential to clean the feed
pipes thoroughly to avoid the risk of metal or other particles entering the
tank or the water heater.
Cold water piping should be provided with a 350 – 500 kPa Pressure
Limiting Valve at the point of cold water connection to the water heater.
In addition to the Pressure Limiting Valve, it is a requirement of AS
3500.4 & NZBC G12 that both a Stop Valve and a Non Return Valve are
installed upstream of the Product.
