SAFETY, WARNINGS, INSTALLATION NOTES
8
Servicing of a water heater must only be carried out by qualified personnel. Phone Rheem Service or their
nearest Accredited Service Agent.
Only a person qualified to install or service a water heater can drain the water heater, if this is required.
Do not modify this water heater.
The water heater has a freeze protection system. The water heater, including the in-series gas booster,
is not suitable for installation in areas where the ambient temperature falls below -20°C (including wind
chill factor). The frost protection system for the gas booster will be rendered inoperable if electrical power
is not available. If it is necessary to switch the power off to the gas booster and there is a risk of freezing,
then it is necessary to drain the gas booster.
Refer to
on page 27 for further information and to
“Draining The Gas Booster Water
on page 14.
Do not spray
aerosols
in the vicinity of this water heater while it is
in operation. Propellants and gases in many aerosol sprays contain
hydrocarbons which are flammable. Gases from aerosol sprays
may also become corrosive when drawn into a flame.
Do not use or store
flammable materials
in or near the gas booster.
Flammable liquids (such as petrol), combustible materials (such as
newspapers) and similar articles must be kept well away from the
water heater and the flue terminal.
Do not store
swimming pool chemicals, household cleaners
,
etc., near the gas booster.
Do not place articles on or against the gas booster, or in contact
with the flue terminal. Ensure the flue terminal is not obstructed in
any way at any time.
Do not use Propane / Butane gas mixtures in a Propane model. A Propane model is designed to operate
on Propane only. The use of Propane / Butane mixture, such as automotive LP gas fuel, in a Propane
model is unsafe and can cause damage to the gas booster.
RELIEF VALVES
Temperature Pressure Relief Valve
This water heater incorporates a temperature pressure relief valve
located near the top of the solar storage tank. This valve is essential for
the water heater’s safe operation.
It is possible for the valve to discharge a quantity of water through the
drain line during each heating period. This quantity should be equal to
approximately 1/50 of the hot water used, as water expands by this
volume when heated.
Expansion Control Valve
In many areas, including South Australia, Western Australia and scaling
water areas, it is mandatory an expansion control valve is fitted to the
cold water line to the water heater.
The expansion control valve will discharge the quantity of water from its
drain line during the heating period instead of the temperature pressure
relief valve as it has a lower pressure rating.
Valve Operation
Continuous leakage of water from either valve and its drain line may indicate a problem with the water heater.
Refer to
“Temperature Pressure Relief Valve or Expansion Control Valve Running”
on page 22.
Warning:
Never block the outlet of either valve or their drain lines for any reason. A relief valve drain must
be left open to atmosphere, and be installed in a continuously downward direction.
