MAINTENANCE
Even if there does not seem to be a problem with the water heater it is required in the
UK that all gas appliances are serviced every year by a certified gas engineer. This is to
ensure continued safety of the gas appliance. If you need a recommended service
engineer contact Rinnai or your supplier.
Servicing Water Heaters
 Isolate electrics and valve of hot, cold, and gas to unit.
 Check the water filter and strainer to be sure there are no blockages.

Remove the combustion fan and clean the impeller.
 Check the burner for wear or water damage. Vacuum out any debris. Wipe out
chamber.
 Check the heat exchanger for soot or hot spots that could be caused by poor
combustion.
 Clean carbon build up from ionisation and ignition probes.
 Check flue terminal for blockages or potential blockages, check that flue is in good
condition.
 Check all electrical connections are reconnected
 The gas pressures should then be re - set (the procedure is detailed in the manual).
 Verify temperature control by checking temperature at outlet, bear in mind that there
will be pipework losses.
 Check all gas joints inside the unit with an electronic gas detection device when
starting unit.
 Leak check all joints back to the service valve (commercial installations) or tightness
test the installation for domestic installations.
CARE
When the appliance casing, operation panel, and control surfaces become dirty gently
wipe them clean with a soft, damp cloth. Do not use detergents on these parts.
The inlet pipe has a water filter which needs to be checked occasionally. This can be
removed by isolating the water, and unscrewing the filter. The plug must be removed
first, followed by the filter. The filter is attached to the plug with a bayonet fitting.
