OPERATING THE FIRE
The flame sensing device.
For your safety, this appliance is fitted with a device which will automatically shut off the gas supply to the fire if the pilot
flame goes out. It will also shut off the gas supply if the flue is blocked or if there is not enough ventilation.
If this device
starts to frequently shut off the gas, get expert advice.
This device incorporates a probe which senses that the heat from the pilot flame is correct. If this probe is cool, the device
will prevent any gas flow unless the control is held at the ignition position.
If, for any reason, the flames go out when the fire is hot or if the fire is turned off when hot, always
wait at least three
minutes before attempting to relight
.
To light the fire
Rotate the control to the pilot position and
depress. Press the piezo button repeatedly.
There may be a delay before the pilot lights
due to air being purged from the system.
When the pilot burner is operating properly,
gradually turn the control knob anti-
clockwise to HIGH (Depress the knob
slightly to get past the LOW position). The
main burner should now light. Depress the
control knob slightly to release from the
HIGH position and turn back (clockwise) to
LOW. While turning, the burner flames
should gradually become lower but remain
alight. Depress the control knob slightly to
release from the LOW position and turn
back (clockwise) to IGN. The main burner
should extinguish but the pilot should
remain alight. Depress the control knob
slightly and turn back (clockwise) to turn
OFF this will extinguish the pilot. See fig 1.
