WATER NOT HOT ENOUGH
You may find that due to heavy hot water usage the water temperature may be
lower than normally expected.
WATER TEMPERATURE TOO HIGH
A RheemPlus water heater is fitted with a temperature limiting valve set to
deliver water not exceeding 50
°C. If the water is being delivered at a
temperature exceeding 50
°C, phone your nearest Rheem Service Department
or Accredited service Agent to arrange for an inspection. Care must be taken
by all householders when using hot water until the valve is serviced or
replaced.
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 seconds
(refer to
“Temperature Pressure
Relief Valve” on page 9). 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.
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 gas control must be turned off using the knob on top of the gas control
thermostat (refer to
“Close Down Procedure” on page 29). Phone your
nearest Rheem Service Department or Accredited Service Agent to arrange
for inspection.
