LIGHTING THE WATER HEATER
34
LIGHTING INSTRUCTIONS
Using the gas control light the water heater as follows:
1. Stop, read the safety information on page 33.
2. Remove the access cover of an outdoor model.
3. Turn the gas control knob fully clockwise to the “” (off) position.
4. Remove the front cover below the gas control of an indoor model.
5. Wait five (5) minutes so any build up of unburnt gas can escape. If you then smell gas, stop and follow
“C” in the safety information. If you do not smell gas, proceed to step 6.
6. Turn the knob to the “” (pilot) position.
7. Depress the knob fully (until star disappears below housing) and after 30 seconds, whilst keeping the
knob depressed, repeatedly press the igniter button (for up to 40 seconds) until the pilot flame ignites.
Warning: Keep your face clear of the combustion chamber opening while pressing the igniter.
Note: It is not possible to depress the knob fully if the gas control has activated its safety shut-off
feature. In this case, wait 60 seconds for the gas control to reset.
8. Keep the knob depressed for 20 seconds after the pilot flame lights.
9. Release the knob and check the pilot is still alight. The pilot can be checked by looking through the large
opening below the gas control.
10. If the pilot has failed to light or has not remained alight, turn the gas control knob to the "” (off) position.
Wait five (5) minutes for any unburnt gas to escape and then begin again at step 6.
Warning: Failure to wait five (5) minutes may result in a fire or explosion.
11. When the pilot flame remains alight with the gas control knob released, turn the knob anticlockwise to
the setting of „6‟. This will give a water temperature of about 60°C.
If this water heater is installed as an in-series booster water heater as part of a commercial solar water
heating system, then Rheem recommends the thermostat is set at 60°C to maximise solar contribution.
12. Refer to “Temperature Adjustment” on page 5, if further temperature adjustment is required.
13. Replace securely the access cover of the outdoor model or the front cover of the indoor model.
The main burner will now automatically ignite when heating is required and extinguish when the water has
been heated to the set temperature. If the main burner does not light at the selected setting, the water may
already be at the selected temperature.
Note: Never press the igniter button while the top knob is in a numbered position.
