LIGHTING THE WATER HEATER
FOR YOUR SAFETY READ BEFORE LIGHTING
Warning:
This
gas water heater is designed to operate reliably and safely as long as the lighting procedure
is followed
exactly
.
Make sure the water heater is filled with water and the water supply is on, otherwise serious damage to the
vitreous enamel cylinder lining and plastic components may occur.
The installer must purge the gas line up to the gas control (refer to
on page 32), check all gas
connections for leaks, gas supply pressure, test point pressure (refer rating label).
Notes
•
625275 indoor model - remove the transport clip from the flue damper
housing.
•
A viewing window is provided to check burner operation on the water
heater.
LIGHTING PROCEDURE
The water heater incorporates an automatic ignition system.
1. Switch on the electrical supply at the isolating switch to the water heater.
2. When the controlling thermostat registers heating is required, the hot surface igniter rod warms up for
20 seconds. The burner will automatically ignite.
3. If burner ignition is unsuccessful, a second and third re-ignition attempt will occur after a five (5) minute
delay between each try. This delay is to allow for any build-up of unburnt gas to escape.
4. If the third attempt is also unsuccessful, the system enters the re-ignition attempt lockout mode. To reset
the water heater, press the illuminated red reset button. The button is located on the left hand side of the
front cover and above the gas inlet. If the water heater fails to light, phone Rheem Service or their nearest
Accredited Service Agent to arrange for an inspection.
