Description of Controls (GP8910GE Model Shown)

Lighting Griddle- Pilots
Caution
SURFACE TEMPERATURE OF THE GRIDDLE PLATE CAN REACH OVER 235°C WHEN THE APPLIANCE IS OPERATED AT FULL SETTING.
These griddles are fitted with a pilot as a standard option and Flame Failure Protection, which is incorporated by way of a thermo-electric system for each main burner. Flame Failure Protection will shut off gas supply to burner in event that 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 gas control knob and rotate anti-clockwise to ‘PILOT’ position.
2. With gas control knob held in depressed position, to ignite pilot burner, press piezo ignition button located on griddle control panel to the right of gas control knob. (Each press of piezo igniter button will generate a single spark).
3. Hold ‘IN’ gas control knob for approximately 10-15 seconds, then release. Pilot burner should remain alight. (If not, repeat Steps 1 to 3 above).
4. Pilot ignition can be viewed through opening in piezo igniter plastic surround.
5. To light remaining pilots, repeat Steps 1 to 4 above.

NOTE: If pilot burner goes out during normal operation wait 5 minutes before attempting to re-light pilot burner.

Lighting Griddle – Main Burners

1. Ensure pilot burner is alight by checking through opening in plastic surround fitted to piezo igniter button on front control panel.
2. Rotate gas control knob anti-clockwise to desired temperature marked on knob.
3. Main burner will ignite automatically off pilot burner.

Re-Setting Overtemp Device (AII UK Chrome Plate and optional AII Other Models)
This griddle is fitted with an overtempt device which isolates gas supply to burners should gas control system or thermostat malfunction, thus preventing overheating of griddle. If pilot fails to ignite after several attempts, ensure that overtempt is checked to ensure that it has not tripped.

1. To reset overtempt, remove gas control knobs from front of griddle. These are a push fit onto spindle of gas valves.
2. Slacken 2 screws securing front control panel to front of griddle and carefully remove control panel, ensuring that leads to piezo igniter are disconnected from rear of piezo buttons.
3. Using a small screwdriver, depress Centre of overtempt reset button.
4. Re-connect piezo igniter leads to rear of piezo igniter buttons.
5. Refit front control panel onto griddle and secure in position with 2 securing screws.
6. Refit gas control knobs to gas spindles.
7. Attempt to re-light pilot burners as shown above. Should pilot burners still not ignite, call a qualified service person to investigate problem.

Turning ‘Off’ Griddle Main Burner / Pilot

1. Turn gas control knob clockwise to pilot position. Main burner will extinguish and pilot burner will remain alight.
2. To turn ‘OFF’ appliance completely, turn gas control knob fully clockwise to ‘O’ position, pilot burner will extinguish.

IMPORTANT
Should any abnormal operation like;

• ignition problems,
• abnormal burner flame,
• burner control problems,
• partial or full loss of burner flame in normal operation, be noticed, the appliance requires IMMEDIATE service by a qualified service person and should not be used until such service is carried out.

Oven

IMPORTANT
DO NOT USE aluminum foil or trays directly on cast iron sole plate(s). NEVER block or cover openings on each side of sole plate(s).
Oven is fitted with top and bottom elements. Thermostat maintains overall oven temperature. Top element is further controlled by oven top heat control. Convection Ovens (GP8910GEC / GP8121GEC) are fitted with a circulation fan.

NOTE: Thermostat on oven provides overall control of temperature within oven by controlling both elements, where as Oven Top Heat Control provides a means of balancing distribution of heat between top and bottom of oven.

Place oven racks in desired position.

Preheat:
Preheat oven by selecting desired temperature, and turning oven top heat control (Refer to Fig 5 on page 12) to a maximum of 2. When desired temperature is reached, amber neon will go out.

Cooking:
IMPORTANT DO NOT USE aluminum foil or trays directly on cast iron sole plate(s). NEVER block or cover openings on each side of sole plate(s).
When desired temperature has been reached, load oven with product and set oven top heat control to desired setting.

NOTE: When oven top heat control is set to a high setting, proportionally more heat is produced at top of oven. (This can be used for browning, etc, during cooking operation). With oven top heat control set on a low setting, less heat is produced from top oven elements. (This mode is used for general baking purposes to prevent cakes, etc, from getting too brown and crisp on top, but allows the cake to cook through).
To obtain more top heat during cooking, turn oven top heat control to a higher position. (The higher the setting, the more top heat).

Turning ‘OFF’ Oven:

• Turn oven top heat control to ‘O’ off position. Top heating will be turned ‘OFF’ and upper heating indicator lamp (Amber) will extinguish.
• Turn thermostat control knob to ‘O’ off position and lower heating indicator lamp (Amber) will extinguish. Oven is now turned ‘OFF’.

Cleaning and Maintenance

General
Caution
Always turn ‘Off’ electrical and gas supply before cleaning. This appliance is not water proof. Do not use water jet spray to clean interior or exterior of this appliance.

Clean the range regularly. A clean range looks better, will last longer and will perform better. Carbonised grease on the surface or on griddle plate will hinder transfer of heat from cooking surface to food. This will result in loss of cooking efficiency.

NOTE: Each Heavy Duty Griddle is supplied with a scraper tool and a pack of blades for cleaning the griddle surface.

• 1 Flat Blade (pack) – 1 Ribbed Blade (pack) and 2 handles for Ribbed Heavy Duty Griddle.
• 1 Flat Blade (pack) and I handle for Smooth Heavy Duty Griddle.

Warning
BLADES FITTED TO SCRAPER TOOL ARE EXTREMELY SHARP AND ARE TO BE USED WITH CARE.

NEVER use ribbed scraper blade on flat chrome surfaced griddle plate.
Replacement blades and handles can be purchased separately. Refer to ‘Replacement Parts List’ at rear of manual.
DO NOT use water on griddle plate while this item is still hot as warping and cracking may occur. Allow griddle plate to cool down before cleaning.

NOTE:

• DO NOT use abrasive detergents, strong solvents or caustic detergents as they could corrode or damage the range.
