Troubleshooting

Check the following information before making a service call as some performance
characteristics are a normal part of operation. If you are still unsure or concerned after reading
this section, please contact Rinnai.
Using the heater for the first time or after long periods of non-use
Ignition may not occur the first time it is operated due to air in the gas pipes. If ignition does
not occur within approximately 60 seconds the appliance will attempt to re-light. 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 expansion and
contraction of the internal components and is normal.

Explanation
The room air fan starts automatically after a short
delay. This is to allow the appliance to warm up,
helping avoid cold draughts.
This is caused by grease, oil or dust within the
appliance. This will stop after a short time.
This is expansion and contraction of the heat
exchanger and is a normal part of operation.
This is the sound of the gas valve opening and closing
to regulate the flow of gas.
This is to remove residual heat from within the
appliance. This stops once the unit cools.
High efficiency appliances tend to discharge water
vapour on cold days. This is normal.
Check timer. Timer must be in the OFF position for
manual operation.
Room temperature is hotter than the High setting.
They may be inactivated or incorrectly programmed.
Check timers are set correctly and the clock is on the
correct time.
Room temperature may be higher than the set
temperature. Increase temperature if desired.
