OPERATION
Burner Operation
The burners on the appliance have fixed aeration and no adjustment is required. The burners
should flame as follows:-
Propane -
The flames should burn quietly with a blue/green colour with no sign of yellow tips.
Butane -
Normally on initial lighting, a small amount of yellow tipping will occur and then
slightly increases as the burner heats up.
1. Ensure gas cylinder/supply is connected and turned on. In the event of a gas smell turn off at
gas cylinder/mains and contact supplier.
2. Flame supervision: Each burner is controlled individually and is monitored by a
thermocouple probe. In the event of the burner flames being accidentally extinguished, turn
off the burner control and do not attempt to re-ignite the burner for at least one minute.
3. To light: Push in the control knob and turn to full rate – see Fig.1. Hold a lighted match or
taper to the burner and push the control knob in and hold. It is necessary to hold the knob
depressed after the burner has ignited for approximately 10 - 15 seconds, to allow the
thermocouple probe to reach temperature, before releasing the knob. Should the flame go
out when the knob is released, the procedure should be repeated holding the knob
depressed for slightly longer.
4. For models fitted with optional Spark Ignition the procedure is similar:-
Models with Auto Spark Ignition – pushing the control knob automatically starts the
spark ignition circuit . To light the burner follow the procedure in (3) above except the
burner is automatically ignited.
Models with Manual Spark Ignition – follow the procedure in (3) above, except that the
burner can be ignited by depressing the ignition button located on the fascia.
If the burner has not lit within 15 seconds the control knob should be released and the
burner left for at least 1 minute before a further attempt to ignite the burner.
5. For simmering, turn the knob further anti-clockwise to the low rate position.
6. To turn off: Turn the control knob until the line on the control knob is aligned with the dot on
the control panel. Always make sure the control knob is in the off position when you have
finished using the hotplate burners.
