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.
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 the discharge is deemed excessive (more than 2% of hot water used), 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 36). Phone your nearest Rheem Service Department or Accredited Service Agent to arrange for inspection.
