PIPE SIZES
The pipe sizing for hot water supply systems should be carried out by persons competent to do so, choosing
the most suitable pipe size to ensure adequate flow for each individual application. Reference to the technical
specifications of the water heater and local regulatory authority requirements must be made.
To achieve true mains pressure operation, the cold water line to the water heater should be the same size or
bigger than the hot water line from the water heater.
The minimum recommended cold pipe or solar preheat pipe and hot pipe size is DN20.
IN-SERIES BOOSTER
The pipe work between the solar storage tank (if one is installed) and the in-series gas booster has a minimum
recommended pipe size of DN20 and MUST BE of copper unless a braided flexible hose is provided with a
solar water heater connections kit for this purpose.
The pipe wor
k or braided flexible hose shall be fully insulated with a closed cell type insulation or equivalent in
accordance with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant
if exposed. The insulation must be fitted up to the connections on both the solar storage tank and the in-series
gas booster.
A full flow isolation valve may be installed on the solar preheat water line from a solar storage tank to the in-
series gas booster.
GAS INLET
The gas connection is made at the underside of the water heater. The pipe work must be cleared of foreign
matter before connection and purged before attempting to operate the water heater. An isolation valve and
disconnection union must be installed to allow servicing and removal of the water heater (refer to the diagram
on page 33).
Note: Refer to the Gas Installations Standard AS/NZS 5601.1 for the correct method of sizing the gas supply
pipe to the water heater. The pipe size selection must take into account the high gas input of this water heater
(refer to table on page 30) as well as all of the other gas appliances in the premises.
Warning: Always isolate the water heater before pressure testing the gas supply system. Disconnect the
water heater after the isolation valve to prevent the risk of serious damage to the gas control. The Rheem
warranty does not cover damage of any nature resulting from failure to observe this precaution. Refer to rating
label for gas types and pressures.
