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"
page 12). 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 gas control must be turned off using the knob on top of the gas control
thermostat (refer to
Service or their nearest Accredited Service Agent to arrange for inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater
(refer to page 29)
temperature pressure relief valve on the water heater. The benefit is that
energy is conserved as the discharged water is cooler.
CAN'T LIGHT THE PILOT FLAME
Is there gas to the water heater?
Check the gas isolation valve on the gas
supply line is open.
Is there a normal gas supply to the rest of
the premises?
Try lighting another gas appliance to check. If
there is no gas, call the gas supplier.
