COLLECTOR GLASS
The Rheem warranty DOES NOT cover breakage of solar collector glass. Check your household insurance
policy covers collector glass breakage.
Warning: No attempt should be made to remove or replace broken collector glass.
The collector glass is not offered as a replacement part. Should a solar collector require replacement, contact
Rheem Service or their nearest Accredited Service Agent.
TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable this valve allows a small quantity of water
to escape during the heating cycle. However, if it discharges more
than a bucket full of water in 24 hours, there may be another
problem.
Continuous dribble
Try gently raising the easing lever on the relief valve for a few
"Temperature Pressure Relief Valve"
seconds (refer to
This may dislodge a small particle of foreign matter and clear the
fault. Release the lever gently.
Steady flows for long period (often at night)
This may indicate the mains water pressure sometimes rises above
the designed pressure of the water heater. Ask your installing
plumber to fit a pressure limiting valve.
Warning: Never replace the relief valve with one of a higher
pressure rating.
Heavy flows of hot water until the water heater is cold - then
stops until water reheats
The water heater must be switched off at the isolating switch or
switchboard. Phone Rheem Service or their nearest Accredited
Service Agent to arrange for an inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water
heater (refer to the
cold water connection diagram
discharge a small quantity of water instead of the temperature pressure
relief valve on the water heater. The benefit is that energy is conserved
as the discharged water is cooler.
PRESSURE RELIEF VALVE DISCHARGING
A pressure relief valve is incorporated into the in-series gas booster
controls. This valve protects the in-series gas booster, by allowing water
to escape, in the event of excessive pressure build up in the waterways.
Normal operation
A small volume of water may discharge from the bottom of the in-
series gas booster when a hot tap is suddenly closed.
Continuous dribble
A continuous dribble may indicate the water supply pressure is
above the design pressure for the in-series gas booster. If so, a
pressure limiting valve must be installed on the cold water supply
pipe to the water heater (refer to
CLOUDS OF WHITE 'VAPOUR' FROM THE FLUE TERMINAL
During the heating cycle, it is not unusual to see water vapour clouds
steaming from the flue terminal, particularly on cold days. This is normal
operation of the in-series gas booster.
