Operation

WARNING:

SURFACE TEMPERATURE OF THE GRIDDLE PLATE CAN REACH OVER 300°C WHEN THE APPLIANCE IS OPERATED AT FULL SETTING.

Lighting the Pilot Burner

These griddles are fitted with a pilot as a standard option and flame failure protection, which is incorporated for each main burner, by way of a thermo-electric system. Flame failure protection will shut off the gas supply to that burner in the event that the pilot for that burner goes out, so that un-burnt gas is not expelled. This is an important safety feature which is slowly becoming law throughout the world.

1. Depress the gas control knob and rotate anti-clockwise to the „PILOT‟ position.

2. With the gas control knob held in the depressed position, depress the piezo igniter button located on the front control panel to the left of the gas control knob, to ignite the pilot burner. (Each depression operation of the piezo igniter button will generate a single spark).

3. Hold in the gas control knob for approximately 10-15 seconds, then release. The pilot burner should remain alight. (If not repeat these 3 steps).

4. Pilot ignition can be viewed through the hole between piezo lighter button and dial.

NOTE: If the pilot burner goes out during normal operation wait 5 minutes before re-lighting.

Lighting the Main Burner

1. Ensure that the pilot burner is alight by checking through the hole between the piezo igniter button and dial on the front control panel.

2. Rotate the gas control knob anti-clockwise to the desired temperature mark .

3. The main burner will be ignited automatically by the pilot burner.

Turning 'Off' the Main Burner / Pilot

1. Turn the gas control knob clockwise to the pilot position. The main burner will extinguish and the pilot burner will remain alight.

2. To turn 'OFF' the appliance completely, turn the gas control knob fully clockwise to the 'O' position, the pilot burner will extinguish.

Note:

Please wait at least 15 seconds to restart the main burners to maintain the best function of the thermostat valve after turning off the main burners.
