1.4.3 SERVICE

A regular maintenance should be made to preserve the appliance integrity and to keep safety,
efficiency and reliability unchanged.
NOTE
Water controllers and water heaters do not contain user serviceable parts and must only be
serviced and repaired by an authorised person.
Rinnai has a service and spare parts network with personnel who are fully trained and equipped to
give the best service on your Rinnai appliance. If your appliance requires service, please call our
national help line.
When making a service enquiry, having both the model and serial numbers available, will help our
staff quickly identify your appliance and better attend to your needs.
Always keep the appliance clean.
Unplug the appliance and turn the main gas valve off before to proceed with
any cleaning or maintenance.
Clean the chassis and the remote controller using soft cloth only.
After maintenance (or cleaning), check to ensure that all the components
of the appliance are intact and connected in the correct way. Exhaust gas
leakage could be harmful for health or result in death.
The water heater has a filter on the cold water inlet connection. This filter will
need to be cleaned occasionally. How often will be determined by the local
water condition; contact Rinnai or ask your installer for information. Isolate
the cold water inlet and hot water outlet with the valves near the heater.
Release the pressure in the heater by unscrewing the drain valve. Then
remove the filter, clean it and replace it.
If the inlet filter is clogged up, it could decrease the performance of the
appliance and shorten its service life. The user should clean the filter
regularly to preserve a proper operation and to prevent the appliance failure.
