IN-SERIES BOOSTER – REMOTE LOCATION
The pipe work between the solar storage tank and the in-series gas booster has a minimum recommended
pipe size of DN20, MUST BE of copper and 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 must be
installed on the water line to the in-series gas booster.
TEMPERATURE PRESSURE RELIEF VALVE
The temperature pressure relief valve is shipped behind the lower front cover of the water heater. The
temperature pressure relief valve must be fitted before the water heater is operated. Before fitting the relief
valve, make sure the probe has not been bent. Seal the thread with Teflon tape - never hemp. Make sure the
tape does not hang over the end of the thread.
Screw the valve into the correct opening (refer to the installation diagram on page 32) leaving the valve outlet
pointing downwards. Do not use a wrench on the valve body - use the spanner flats provided. A copper drain
line must be fitted to the temperature pressure relief valve (refer to "Relief Valve Drain" on page 41).
The valve must be insulated with closed cell polymer insulation or similar (minimum thickness 9 mm) and the
insulation installed so as not to impede the operation of the valve. The insulation must be weatherproof and
UV resistant if exposed.
EXPANSION CONTROL VALVE
Local regulations may make it mandatory to install an expansion control valve (ECV) in the cold water line to
the water heater. In other areas, an ECV is required if the saturation index is greater than +0.4 (refer to
“Water Supplies” on page 14).
The expansion control valve must always be installed after the non return valve and be the last valve
installed prior to the water heater (refer to diagrams on page 38). A copper drain line must be fitted to the
expansion control valve (refer to "Relief Valve Drain" on page 41).
The valve must be insulated with closed cell polymer insulation or similar (minimum thickness 9 mm) and the
insulation installed so as not to impede the operation of the valve. The insulation must be weatherproof and
UV resistant if exposed.
