In-series Gas Boosting
Integrity Solar Hiline
Installation
Note: This plumbing diagram is
also applicable to standard model
heaters fitted with a comparator.

Where one of the above listed models is installed to provide in-series gas boosting, a solar
bypass valve is fitted across the Integrity inlet and outlet water connections to prevent the
water heater from operating when the outlet water temperature from the solar system is
above 57°C (refer to diagrams on page 17). A disconnection union must always be
provided at the solar preheated water inlet and hot water outlet on the solar bypass valve
to allow for removal of the valve.
The solar bypass valve has been specifically designed to work with Rheem Integrity
models listed above. 20 and 26 models ending with a B do not require a bypass valve. 24
models ending with -C do not require a bypass valve. 18 litre Integrity‟s are not suitable
for use as in-series boosters.
The preset outlet temperature of the Integrity, when installed as an in-series gas booster to
a solar water heater, must be set at 60 C for the system to operate correctly.
The factory preset outlet temperature of all Integrity models is 55 C; during a new
installation it will be necessary to reset the outlet temperature to 60 C. Refer to page 4 for
details on checking and adjusting the outlet temperature.
There are two types of solar bypass valves currently in use (Paloma & RMC) and whilst
both operate in the same manner the plumbing arrangement at the valve differs according
to the type of solar bypass valve used (refer to diagrams on page 17). Solar bypass valves
are no longer available and if faulty are to be removed and a Comparator installed. Refer
to pages 17 & 18 for information on comparators.
