11.2.2 Burner Lockout Reset Button
The red warning light built into the burner control
box will illuminate when the control has gone to
lockout. This may be caused by flame failure. Wait
one minute then press the reset button.
11.3 Lighting Instructions (all models)
11.3.1 To Turn On Heater
1. Ensure that the electrical and gas supplies to
the heater are on. Check that the on-site con-
trols are “ON”.
NOTE: The thermostat setting must be above the
ambient temperature for the heater to operate.
2. The automatic firing sequence will begin as
described on Page 40, Figure 19. The heater
will now operate automatically under the control
of the on-site controls. Following long shut
down periods, the control may go to lockout.
See Page 41, Section 11.2.2.
11.3.2 To Turn the Heater Off
Set the installed remote controls to the “OFF”
position or turn down the remote thermostat below
the ambient temperature.
The burner will turn off immediately.
The fan will continue to run for a few minutes.
To restart, turn the remote control to “ON".
If the heater will remain off for a long period of time,
when the main fan(s) have stopped, turn off the fuel
supply valve and main electrical isolator. To restart
open the fuel supply valve and follow the
instructions in Section 11.3.1.
11.4 Simple Fault Finding (all models)
Some possible reasons for the heater not operating
are:
1. Gas supply not turned ON.
2. Electricity supply not turned ON.
3. The time and/or temperature controls are not
ON.
4. The Limit Thermostat may have operated. This
may be caused by an interruption of the electri-
cal supply or failure of the distribution fan.
5. The burner supply plug has been discon-
nected.
If the Limit Thermostat persistently operates, there
is a fault which must be investigated by a contractor
qualified in the installation and service of gas or oil-
fired heating equipment.
NOTE: If the main fan runs continuously, the white
button (Figure 20) may have been pressed in - make
sure it is pulled out. Alternatively, if a remote fan
switch is fitted it may be in the ON position.
11.4.1 Simple Fault Finding (burner faults)
If the burner fails to ignite for any reason, it will go to
lockout. This will be indicated by the red light on the
heater or at the remote indicator (if fitted).
1. Press in and release the lockout reset button on
the burner or, if fitted, the remote reset.
Lockout should not occur during normal operation of
the heater and indicates there is a fault condition
which must be corrected.
11.4.2 Simple Fault Finding (oil fired heaters)
Make sure the appliance fuel valve is open and
there is oil in the tank. If the fuel tank or lines have
run dry, the fuel system will need to be vented. For
venting oil-fired heaters, See Page 38, Section 10.6
through Section 10.7.5.
If control locks out, do not make more than 3
attempts to restart the heater.
Dangerous fuel mixtures can build up.
The fault must be traced and repaired by a
registered installer or service engineer.
Failure to follow these instructions can result in
death, injury or property damage.
