User Instructions

If the heater has not been left operational
proceed as follows.

A) Checks before operating the Air
Heater

The following preliminary checks should be made before
lighting the heater(s)

a) Ensure that the ELECTRICAL supply to the heater is
switched OFF.
b) Check that any warm air delivery outlets are open.
c) Check that the thermostat is set.
d) Check that the clock control is set to an ON period.
e) Check that any other controls are calling for heat.

B) Operating the Air Heater

1) Gas-Fired Heaters

1. Switch on the electrical supply at the isolator.

2. The burner air fan will run and after a pre purge period
of approximately 30 seconds the ignition spark will be
generated.

CPx 30 - 90

The main gas valves will open and the main burner will be
established

CPx 120 - 300

The start gas valves will be opened and a start gas flame
established. When a start gas flame is established the
main gas valves will be energized and the start gas flame
will expand to main flame.

NOTE: If the burner fails to light it will go to
lockout and the lockout indicator / reset
button on the burner control box will be
illuminated. To restart the burner push the

reset button.

2) Oil-fired Heaters

IMPORTANT: If it is not possible to light the
heater after 2/3 attempts contact the local
service company.

1. Switch on the electrical supply at the isolator.

2. The burner air fan will run and after a pre purge period
of approximately 30 seconds the ignition spark will be
generated and the oil valve opened. The main burner will
then fire.

NOTE: If the burner fails to light it will go to
lockout and the lockout indicator / reset button
on the burner control box will be illuminated. To
restart the burner push the reset button.

If the unit will not light after two to three
attempts then shutdown the unit and call in
a service engineer.

C) To Shut Down the Air Heater

1) For Short Periods:

Turn the room thermostat to the OFF, or set to it’s lowest
setting.

2) For Long Periods:

Complete step 1 above. Wait for 5 minutes and then turn
OFF the electrical supply at the isolator.

D) Description of Operation

Important: All heaters must be controlled by the fitted
external controls and not by use of the main switch in the
electrical supply to the heater.

The burner start up sequence will commence when the
controls e.g. timeclock, room thermostat etc. call for heat.
The burner air fan will run and after a pre purge period the
burner will light.

IMPORTANT: If the unit will not light after
four or five attempts then shutdown the unit
and call in a service engineer.

WARNING: If the main burner or a start gas
flame fails to establish the burner will go to
lockout and the lockout indicator / reset

button on the burner control box will be
illuminated. To restart the burner push the lockout reset
button. Additional, more easily accessible, controls may
be fitted that mimic the lockout indicator and reset
button functions. If the unit will not light after four or
five attempts then shut down the unit and call in a
service engineer.

CPx Range Users, Installation & Servicing Instructions Doc Ref M201 issue 2.9 Nov 2018.

Approximately 2/3 minutes after the burner lights the
heater fan will automatically start.

When the external controls are satisfied the burner will
be turned off and approximately 4 to 5 minutes later the
heater fan will automatically stop.

1) Summer / Winter Modes

Certain types of external controls will provide for two
modes of operation i.e.
Summer: The heater fan alone will run at the
dictate of the external controls to provide
air movement.
Winter: The heater will operate normally.

E) Fan and Limit Control

The fan and limit controls are mounted towards the top of
the air heater upper front panel.

User Instructions

Warning: Flammable Materials

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.

Warning: Hot Surfaces

Warning: Contains Moving Parts
