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