CLEANING

Your heater needs very little maintenance, but the following information will help you to keep it looking good and
working efficiently.
DO NOT attempt to clean the heater while the appliance is hot or operating.
All parts of the heater can be cleaned using a soft, damp cloth.
WARNING
DO NOT use solvents or abrasives to clean any parts.
DO NOT spray aerosols in the vicinity of the heater whilst in operation.
DO NOT place articles on or against this heater.
DO NOT store flammable materials near this heater.
DO NOT remove any panels or attempt to carry out any service work other than that which is
mentioned in the Trouble Shooting Checklist "Trouble Shooting Checklist" on page 14.

NORMAL OPERATIONAL CHARACTERISTICS

During the initial burning in period some fumes and smell may be experienced. This condition may last for a couple
of hours, however this is a normal part of the burning in process.
When using the heater for the first time, or after a long period of non use the ignition may not occur the first time it
is operated due to air in the gas pipes. If ignition does not occur the unit will switch off automatically. Try operating
the heater again if this occurs, if this continues however then contact Rinnai for advice.
The heater may make noises after ignition or switching off. This is due to the expansion and contraction of the
internal components and is normal.
As a safety precaution the heater will not ignite if the Standby / ON button is pressed straight after the heater has
been turned off. It will take approximately 20 seconds for the unit to reset and switch back on again.

TROUBLE SHOOTING

General Operation Characteristics
Before asking for a service call please check the following table as these characteristics are part
of the normal operation of the appliance and do not indicate a fault.
NOTE
Characteristic
At ignition:
Warm air does not start when the burner
lights.
Smoke or strange smells are produced on the
first start up after installation.
Sharp clicking noises at ignition, or when
the unit thermostat modulates to a lower or
higher setting, or shuts down.
During combustion:
Dull clunking noise when the thermostat
operates.
When the appliance is turned off:
Convection fan continues to run after turning
'OFF'.
Rinnai
Explanation
The fan is started automatically after a short delay. This is
to allow the heat exchanger to warm up, helping to avoid
cold draughts.
This is normal operation.
This is caused by manufacturing oil or dust on the heat
exchanger.
This is to be expected and will cease after a short time.
This is simply expansion and contraction noise from the
heat exchanger.
This is a normal operation sound.
This is the sound of the solenoid gas valves opening and
closing to regulate the gas flow.
These are normal operation noises.
This is to remove residual heat from the heat exchanger
and stops once the appliance cools sufficiently.
