TROUBLE SHOOTING
26
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 caused by grease or oil from the
manufacturing process on the heat
exchanger and dust, and will stop after a short time.
This is simply expansion noise from the metal heat
exchanger.
This is the sound of the solenoid gas valves
opening and closing.
This is to remove the residual heat from the heat
exchanger. The fan will stop when the unit cools
down.
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 'High' setting.
Timers may either be inactivated or incorrectly
programmed. Repeat programming. Refer to
"OPERATING THE TIMERS" on page 11.
Room temperature may be higher than set
temperature. Adjust temperature upwards if
desired.
