Energysaver - Operation & Installation Manual
Before asking for a service call please check the following.
These symptoms are part of the normal operation of the unit and do not indicate a fault.
Symptom
Explanation
At Ignition:
Warm air does not start when the burner
lights.
The fan is started automatically after a short
delay. This is to allow the heat exchanger to
warm up, helping to avoid cold draughts.
Smoke or strange smells are produced on the
first trial light up after installation.
This is caused by grease or oil on the heat
exchanger and dust, and will stop after a short
time.
Sharp clicking noises at ignition, or when the
unit cuts down on the thermostat, or goes out.
This is simply expansion noise from the heat
exchanger.
During combustion:
Clunking noise when the thermostat operates.
This is the sound of the solenoid gas valves
opening and closing.
Unit is not heating room
Is the air filter blocked?
Is the set temperature high enough?
Is the warm air outlet blocked by anything?
Are the doors and windows of the room closed?
Air filter is blocked or the louvres are blocked
or obstructed
Allow heater to cool, clean air filter, operate
again.
Heater will not re-ignite after overheating
Even after unit has cooled down the heater does
not ignite again. Repair is necessary. Contact
your local agent or Rinnai for a Service Call.
When the unit is turned Off:
Convection fan continues to run after turning
off.
This is to remove the residual heat from the heat
exchanger. The fan will stop when the unit cools
down.
Other points:
Steam is discharged from the flue terminal.
High efficiency appliances tend to discharge
water vapour on cold days. This is normal.
Heater does not start even when ON button is
pushed and thermostat is on HIGH.
Check timer. Timer must be in the “OFF” position
for manual operation.
Unit cuts off without apparent reason
Check whether filters are blocked, dirty filters will
cause the heater to overheat.
Power Failure
Switch OFF, then ON again when power is
restored to re-set controls.
Timers:
Timers do not operate at set time.
Timers may either be inactivated or incorrectly
programmed. Repeat programming. Refer to
“SETTING THE CLOCK” on page 18.
Timer operates for 30 seconds then cuts out.
Room temperature may be higher than set
temperature. Adjust temperature upwards if
desired.
