BURNER WILL NOT LIGHT
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. If there is no gas call your gas provider.
Is the
ignition system ‘locked out’?
Try resetting the water heater. Refer to “
Water Heater Not Operating
” on page
8
.
Has the High Limit Thermostat tripped?
The manual reset protective over temperature cut out (high limit thermostat) will shut down the water heater in
the event of a fault with the temperature control or water flow. When the system water temperature has cooled
sufficiently, the high limit reset lever can be operated to restart the water heater (refer to
“High Limit
Thermostat
”
on page
34
). Should frequent resetting be necessary, call your nearest Rheem Service
Department or Accredited Service Agent.
PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable that the pressure relief 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 pressure relief valve for a few seconds (refer to
“
Pressure Relief
Valve
” on page
10
). 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 pressure relief valve with one of a pressure rating greater than 850 kPa.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater (refer to
“Cold Water Connection
Plumbing Diagram”
on page
15
) it may discharge a small quantity of water instead of the pressure relief valve on
the water heater. The benefit is that energy is conserved as the discharged water is cooler.
HIGH GAS BILLS
Should you at any time feel your gas account is too high, we suggest you check the following points:
Is the relief valve running excessively? (Refer to
“Pressure Relief Valve Running”
on page
9
).
Are outlets (especially the showers) using more hot water than you think? (Refer to
“Not Enough Hot Water”
on page
8
).
Is there a leaking hot water pipe, dripping hot water tap, etc? Even a small leak will
waste a surprising quantity of hot water and gas. Replace faulty tap washers, and
have your plumber rectify any leaking pipe work.
Consider recent changes to your hot water usage pattern and check if there has
been any increase in tariffs since your previous account.
Is there excessive heat loss from the building? Check that there are no large
uncovered windows or excessive draughts and that ceiling insulation is installed.
Hot water piping should be well lagged (insulated) to reduce heat loss.
IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU NEED ASSISTANCE, PHONE
