VENTILATION
Switch on mains supply to the equipment
Set On/ Standby switch to ON
Set the remote control panel switch to VENT check that
fans rotation is correct
HEAT
The heater has a two stage gas valve and will operate
on high or low fire, the fan is single speed
Set the remote control panel to HEAT
Set the high and low room thermostats to the
desired temperatures
The high fire thermostat should be set at a temperature
approximately 3 degrees lower than the low fire
(control) thermostat setting,
The flue venter will start, activating the differential
pressure switch. After a short period ignition takes
place and after 30 seconds the air flow fan will start
The heater will initially start in high fire operation. When
the set temperature on the high fire thermostat is
reached the gas valve will turn down to low fire and the
heater will continue to operate in low fire until the
desired room (control) temperature is reached.
The burner will shut down and the fan will overrun for
approximately 3 minutes.
IGNITION
Connect the manometer on the pressure test point
on the gas manifold
Set mains isolator to On
Open gas isolator cock
Set the on/standby switch to ‘On’
Set heat/vent switch to Heat
Set the thermostats to the desired temperature’s
Reset any lockout in the system as indicated by the
red or yellow lights
The flue venter will start up activating the differential
pressure switch.
The heater will pre purge the combustion chamber the
electronic control box will supply the ignition electrode
and the gas valve simultaneously.
If the gas line has not been correctly purged ignition
may not take place at the first attempt resulting in
lockout of the burner.
Reset button and repeat.
Before each attempt at ignition it is necessary to
wait at least 10 seconds
When the burner has ignited check the manometer and,
adjust gas pressure high low settings to the pressure’s
indicated on the data plate, and in the manual provided
adjust by turning the solenoid valve adjusters RP1 RP2
on gas valve.
Check the gas consumption reading corresponds
with that indicated in the TECHNICAL DATA section
Set on/standby switch to ‘standby’. When heater is
sufficiently cool Isolate electrical supply Isolate gas
supply
Remove the manometer and ensure the screw at the
test point is tightened to avoid any gas leaks
Open the gas isolating cock Switch on electrical
supply
Set the room (control) thermostat to the desire
temperature. The heater is now ready for operation.
WARNING!
The heater must only be operated with the
burner compartment door(s) closed.
STOPPING
To stop the heater using only the room (control)
thermostat. Set it to the minimum temperature. Fan will
stop after approximately 3-4 minutes.
If required, switch off the mains current at the isolator.
