Reset switch and status lights
The appliance is fitted with an LED status light.
This can be used to determine the current status
of the appliance and help to diagnose fault
conditions. See LED Status table below for more
information.
To turn off the air heater for a short period,
turn the room thermostat to a lower setting (a
voltage below 0.8VDC will be deemed as no
heat demand). To relight, reset the thermostat.
To turn off the heater for a prolonged period,
turn the room thermostat to lowest setting and
turn off the gas supply to the appliance. Switch
off electrical supply to the air heater only after
the air circulation fan has stopped. To relight,
follow the start up instructions.
Gas and electricity must only be turned off in
case of emergency or for prolonged periods of
shutdown of the air heater.
