MAJOR FIVE YEAR SERVICE
It is recommended a major five (5) year service be conducted on the water
heater.
Warning
: Servicing of a gas water heater must only be carried out by
qualified personnel. Phone Rheem Service or their nearest Accredited Service
Agent.
Note:
The five (5) year service and routine replacement of any components,
such as the relief valve(s), are not included in the Rheem warranty. A charge
will be made for this work. Only genuine replacement parts should be used on
this water heater.
The major service includes the following actions:
Replace the temperature pressure relief valve.
Inspect and flush the expansion control valve (if fitted). If required, replace
the valve.
Check and if necessary adjust the inlet gas pressure.
Check the condition and operation of the piezo igniter, gas control and
thermocouple.
Check the operation of and clean the pilot light and main burner.
Visually check the unit for any potential problems.
Inspect plumbing and gas connections.
Note:
The water heater may need to be drained during this service. After the
completion of the service, the water heater will take approximately an hour to
heat the water.
EXPANSION CONTROL VALVE
In many areas, including South Australia, Western Australia and scaling water
areas, an expansion control valve is fitted to the cold water line to the water
heater. The expansion control valve may discharge a small quantity of water
from its drain line during the heating period instead of the temperature pressure
relief valve on the water heater.
Operate the easing lever on the expansion control valve once every six (6)
months.
It is very important you raise and lower the lever gently.
The
expansion control valve should be checked for performance or replaced at
intervals not exceeding five (5) years, or more frequently in areas where there
is a high incidence of water deposits.
