The appliance will wait until the heat exchanger is warmed
up before discharging air. This ensures that any discharge
air will be warm and not cold.
This is caused by grease or oil on the heat exchanger or by
dust and should stop after a short time.
Internal components are cooling (contracting) or heating up
(expanding) at different rates.
This is the sound of the solenoid gas valves opening and
closing to regulate the gas flow.
The fan will continue to run to prevent internal components
from overheating.
Steam discharge is normal.
Timers must be turned off (or press OVERRIDE) for
manual operation.
