Fan control:
The burner should start its safety sequence and then fire up. When the heater
achieves 35°c the supply fan will cut in and your heater is up and running. When
the space is up to temperature the burner will stop and the supply fans will run on
until the fan control reaches 25°c and then the supply fan will shut down. The
heater will then switch on and off as required via the day thermostat and time
clock. If your heater fails to start, check burner lockout and high limit resets as
referred to in fault findings, if any further investigation is required or the heater
repeatedly locks out then a Corgi registered engineer must be called to investigate
further.
Please Note: You must not electrically isolate the heater when in full fire, always
wait until the burner stops and the supply fan over runs to dissipate the heat before
electrically isolating.
For summer ventilation switch on/off switch to off and set fan switch from auto to
manual.
Cleaning Of Heater:
The heater can be cleaned externally using a damp cloth with a light detergent.
Please note: this is on the outer panel only, away from all of the electrics. No
substance can be used that will cause harm to the surface of the metal, or remove
paint etc.
Please Note: You must not use water on unpainted galvanised finished surfaces.
