871024-C Solar Hiline Installation
Note: This plumbing diagram is
also applicable to 871024 &
871024-B model heaters fitted
with a comparator. For more
information on comparators refer
to page 17.
871024 & 871024-B Models
Where an 871024 or 871024-B model Integrity 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
871024 and 871024-B models heaters. Models ending with -C do not require a bypass
valve. 875 series water heaters 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 50°C; during a new
installation it will be necessary to reset the outlet temperature to 60°C. Refer to page 5 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.
