E) Fan and Limit Control
The fan and limit controls are mounted towards the top of
the air heater upper front panel.
i) Main Air Fan MAN/Auto
When the white button is pushed to MAN the fan will run
continuously i.e not controlled by any external controls
e.g. Timeclock. When the white button is pulled out the
fan will start and stop automatically in conjunction with
the burner.
ii) Limit Thermostat
This operates if high temperatures within the heater are
detected, the burner is turned off and a red indicator
light on the front of the heater is illuminated. The fault
condition must be identified and rectified and the
thermostat manually reset.
When the unit has cooled push the reset switch on the
front of the heater to reset the limit thermostat interlock
relay, the red indicator light will go out and the unit is
operational again.
NOTE: The limit thermostat(s) can only be
reset once the unit has cooled down. Unless
the cause of the fault condition is readily
obvious, for example a power cut whilst the
heater was operating, a service engineer
should be contacted.
F) Maintenance
Regular servicing is essential to maintain efficient, reliable
and safe operation of the heater. Users are strongly
recommended to have the heater serviced at least
annually and preferably at the end of the heating season.
IMPORTANT
Free access must be maintained to and
around the heater for servicing purposes
and the air supply to the heater must not be
restricted in any way. Combustible materials must not
be stored adjacent to the heater.

plus electricity to power them, they may also
contain moving parts such as pulleys and

service unless you are a competent person in the field of
Gas and Electrical work.
