ABOUT YOUR WATER HEATER
TO TURN OFF THE WATER HEATER
If you plan to be away from home for a few nights, we suggest you leave the water heater switched on.
If it is necessary to turn off the water heater:
•
Switch off the electrical supply to the solar storage tank and to the in-series gas booster at the power
outlets if there is no risk of freezing conditions occurring (refer to the notes below).
•
Close the gas isolation valve at the inlet to the water heater.
•
Close the cold water isolation valve at the inlet to the water heater.
Notes
•
The in-series gas booster frost protection system will be rendered inoperable if electrical power is not
available at the gas booster. Damage caused by freezing due to the unavailability of power at the in-series
gas booster is not covered by the Rheem warranty (refer to
•
If it is necessary to switch the power off to the in-series gas booster and there is a risk of freezing, then it
is necessary to drain the gas booster (refer to
TO TURN ON THE WATER HEATER
•
Screw in the drain plugs at the cold water inlet and hot water outlet of the in-series gas booster if the gas
booster has been drained.
•
Open the cold water isolation valve fully at the inlet to the water heater.
•
Open all of the hot water taps in the house (don't forget the shower).
Air will be forced out of the taps.
•
Close each tap as water flows freely from it.
•
Open the gas isolation valve fully at the inlet to the water heater.
•
Plug in the solar storage tank and in-series gas booster at the power outlets and switch on the electrical
supplies.
The power outlets must be switched on for the solar controls to operate and solar gain to be achieved and
for the in-series gas booster to operate.
The in-series gas booster will operate automatically when you open a hot tap, if boosting is required.
