Explanation and/or possible solution
The fan starts automatically after a short delay. This
is to allow the appliance to warm up, helping avoid
cold draughts.
This is to remove residual heat from within the
appliance. This stops once the unit cools down.
Ensure the power cord is plugged in and turned on.
Ensure gas supply is turned on.
Possible power failure, or gas supply may have been
turned off.
Unit not plugged in properly or has been turned
off—plug in power cord or press On/Off button.
Remote lock-up due to signal being out of range,
incorrectly aimed at unit or obstructed.
Batteries may be flat, change batteries.
Assembly fault, remote will not respond to
movement—accelerometer not communicating
with the main processor correctly. Contact Rinnai.
Room temperature outside 5-45 °C, or temperature
sensing circuit has failed, which may indicate an
assembly fault. Contact Rinnai.
