MAJOR SERVICE EVERY FIVE YEARS
It is recommended a major service be conducted on the water heater every five (5) years.
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 major service and routine replacement of any components, such as the anode and relief valve(s),
are not included in the Everhot 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.
•
Inspect and if required, replace the anodes.
If the anodes are not replaced, they should be replaced within three (3) years of this service (refer to
“Anode Inspection and Replacement”
on page 16).
•
Check and if necessary adjust the inlet gas pressure.
•
Check the operation of and clean the main burner.
•
Drain and flush the water heater if required.
In commercial applications where large volumes of hot water are used, sediment may build-up on the
bottom of the cylinder and reduce the heating efficiency. In extreme cases, particularly in areas of high
water sediment, draining and flushing out may be necessary.
•
Visually check the unit for any potential problems.
•
Inspect all connections.
•
Check the drain line from the safe tray (if one is installed) is not blocked.
Note:
The water heater may need to be drained during this service. After the completion of the service, the
water heater will take some time to reheat the water. Hot water may not be available for a while.
