Troubleshooting
Check the following information before making a service call as some performance characteristics
of the re are a normal part of operation. If you are still unsure or concerned after reading this
section, please contact Rinnai on 0800 746 624.
During installation there will be an initial burning in period where some smoke and smell may be
experienced, this could last for a couple of hours— this is a normal part of the operation.
The appliance is tted with an overheat safety switch which will shut off the appliance. If the
appliance shuts off repeatedly servicing may be required.
Using the heater for the rst time, or after a long period of non use
Ignition may not occur the rst 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.
The heater may make noises after ignition or switching off. This is due to the expansion and
contraction of the internal components—this is normal. The heater will not ignite if the On/Off
button is pressed straight after the heater has turned off. It will take approximately 20 seconds
before the unit will switch on again.
What’s happening Explanation and/or possible solution
Unusual smells
Smoke or strange smells are produced when
rst operating the appliance after installation.
This is caused by grease, oil, or dust within the
appliance. This will stop after a couple of hours.
Smell of gas Have you been painting? Have new carpets
been laid? Have you been cooking with spices?
If yes to any of the above, then this is normal as
these odours will mix with the warm air to emit an
unusual smell—this will dissipate over time.
There could be a leak. Turn off the gas at the
meter or LPG cylinder and call your installer.
Unusual sounds
Clicking noises when the heater starts or
stops, or changes to a higher or lower setting.
This is expansion and contraction of the heat
exchanger and is a normal part of operation.
Clunking noise when the thermostat operates. This is the sound of the gas valve opening and
closing to regulate the ow of gas.
Soot marks and condensation on the glass
Small soot deposit on logs or stones. Normal operation, no action required.
Severe soot deposits forming on logs, stones,
or glass
Inadequate ue system, incorrect gas pressure
or incorrect installation of burn media. Contact a
Rinnai Service Centre.
Condensation and/or water marks on the
glass
Normal operation. Condensation should
disappear once the re has warmed up. If still a
problem, the glass can be cleaned, refer p. 22.
