alight. (If not repeat Items 2 and 3 above).
Lighting Main Burner
1. Turn gas controls anti-clockwise to first stop (‘FULL’ flame position) and allow griddle plates to heat
up to operating temperature.
2. ‘LOW’ flame can be achieved by depressing gas control knob and rotating fully anti-clockwise.
3. For intermediate heat, position gas control knob between ‘HIGH’ and ‘LOW’ positions to achieve
desired heat.
4. During idle periods, main burners can be turned down to maintain an appropriate plate temperature
or gas controls can be set to ‘PILOT’ position as required.
NOTE:
 Always set gas control knob to ‘HIGH’ position when lighting main burners.
 If pilot burner goes out during normal operation, wait 5 minutes before attempting to
re-lighting pilot burner.
WHEN THE SOLID GRIDDLE PLATE IS USED, IT'SSURFACE TEMPERATURE CAN REACH OVER 350°C WHEN THE
APPLIANCE IS OPERATED AT FULL SETTING.
Warning
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, appliance requires
IMMEDIATE service by a qualified service person and should not be used until such service
is carried out.

Cleaning and Maintenance
General
Clean chargrill regularly. A clean chargrill looks better, will last longer and will perform better.
Carbonised grease on surface or on chargrill will hinder transfer of heat from cooking surface to
food. This will result in loss of cooking efficiency.
NOTE: Each chargrill can be supplied with a chargrill scraper assembly, scraper tool and a
pack of blades for cleaning chargrill surface. These are not supplied with chargrills but
can be purchased separately. Replacement blades and handles can also be purchased
separately. Refer to 'Replacement Parts List' at rear of manual.
DO NOT use water on chargrill while this item is still hot as warping and cracking may
occur. Allow chargrill to cool down before cleaning.
NOTE:
 DO NOT use abrasive detergents, strong solvents or caustic detergents as they could
corrode or damage chargrill.
 To prevent rust forming on chargrill (Steel Plate), ensure that any detergent or
cleaning material has been completely removed after each cleaning. Appliance
should be switched on briefly to ensure chargrill becomes dry. Spread a thin coat of
oil or grease over chargrill surface to form a protective greasy film.
To keep your chargrill clean and operating at peak efficiency, follow procedures shown below:-
After Each Use
1. Clean chargrill with a scraper tool to remove any food debris.
2. Always ensure scraper tool blades are changed regularly to ensure scraper tool works efficiently and
prevents damage to chargrill surface.
Daily Cleaning
1. Crumb tray(s) should be checked and emptied frequently to prevent overflow and spillage. Remove
crumb tray(s) while still warm so that grease is in a liquid state. Empty any grease from trays and
wash thoroughly in same manner as any cooking utensil.
2. Remove grates and radiants and thoroughly clean splash back, interior and exterior surfaces of
chargrill with hot water, a detergent solution and a soft scrubbing brush.
3. Brush chargrill surface with a soft bristled brush. Any carbon deposits should be removed using a
scraper tool followed by wiping with a cloth to prevent accumulation of food deposits.
4. Dry chargrill thoroughly with a dry cloth and polish with a soft dry cloth.
Always turn off the gas supply before cleaning.
This appliance is not water proof.
Do not use water jet spray to clean interior or exterior of this appliance.
Caution
Always ensure that even pressure is applied over whole surface of scraper tool
when using on flat surface of griddle, to prevent scoring of griddle surface.
NEVER bang sharp edge of scraper tool on flat surface of griddle as this will
damage griddle and invalidate the warranty.
Caution
THE BLADES FITTED TO THE SCRAPER TOOL ARE EXTREMELY SHARP AND ARE TO BE USED WITH CARE.
Warning

14
Cleaning and Maintenance
Weekly Cleaning
NOTE:
 If chargrill usage is very high, we recommend that weekly cleaning procedure is
carried more frequently.
 Ensure that protective gloves are worn during cleaning process.
 DO NOT use harsh abrasive detergents, strong solvents or caustic detergents as they
will damage chargrill and burners.
 DO NOT use water on chargrill while grates are still hot as warping may occur. Allow
these items castings to cool and remove for cleaning.
Grates (Cast Iron)
a. Clean grates thoroughly with a wire brush or a flexible spatula.
b. A scraper tool can be used to remove stubborn carbon and
deposits.
c. Clean with hot water, a recommended detergent solution and a
scrubbing brush. Dry all components thoroughly with a dry
cloth.
d. Chargrill should be switched ‘On’ briefly to ensure grates are
dry. Spread a thin film of cooking oil over grates to form a
protective film.
Radiants (Cast Iron)
a. Clean radiants thoroughly with a wire brush or a flexible
spatula.
b. A scraper tool can be used to remove stubborn carbon and
deposits.
c. Clean with hot water, a mild detergent solution and a scrubbing
brush. Dry all radiants thoroughly with a dry cloth.
Main Burners
a. Main burners can be cleaned with hot water, a recommended
detergent solution and a scrubbing brush. Ensure that any
excess water is removed from inside the burners. Dry all
burners thoroughly with a dry cloth.
b. Ensure burners are fitted correctly over main injectors and are
located properly into recesses in chargrill.
Stainless Steel Surfaces
a. Clean exterior surfaces of chargrill with hot water, a mild
detergent solution and a soft scrubbing brush. Note that gas
control knobs are a push fit onto gas control valve spindles and
can be removed to clean control panel.
b. Baked on deposits or discolouration may require a good quality
stainless steel cleaner or stainless steel wool. Always apply
cleaner when appliance is cold and rub in direction of grain.
c. To remove any discolouration, use an approved stainless steel
cleaner or stainless steel wool. Always rub in direction of grain.
d. Remove grease tray and clean with a mild anti bacterial
detergent and hot water solution using a soft bristled brush.

Cleaning and Maintenance
Griddle Plate (Steel - Drop-On) (Optional Extra)
NOTE: To prevent rust forming on chargrill (Steel Plate), ensure that any detergent or
cleaning material has been completely removed after each cleaning. Appliance should
be switched on briefly to ensure chargrill becomes dry. Spread a thin coat of oil or
grease over chargrill surface to form a protective greasy film.
a. Remove and clean grease collection drawer frequently to prevent over spills.
b. Clean griddle surface thoroughly with a scraper tool or wire brush. If necessary use a griddle
stone or a scotch bright pad on griddle surface to remove stubborn or accumulated carbon
deposits..

d. Clean with hot water, a mild detergent solution and a scrubbing brush. Dry all components
thoroughly with a dry cloth.
e. Griddle should be switched on briefly to ensure griddle plate becomes dry. A thin smear of
cooking oil should be spread over griddle to form a protective film.
Periodic Maintenance
NOTE: All maintenance operations should only be carried out by a qualified service person.
To achieve best results, cleaning must be regular and thorough and all controls and mechanical parts
checked and adjusted periodically by a competent serviceman. If any small faults occur, have them
attended to promptly. Don't wait until they cause a complete breakdown. It is recommended that
appliance is serviced every 6 months.
Gas Control Valve Re-Greasing
Gas control valve should be dismantled and greased every 6 months to ensure correct operation.
To carry out this operation;-
a. Remove gas control knobs from gas tap spindles.
b. Remove drip tray from appliance.
c. Remove two screws on underside of control panel and remove
control panel.
d. Remove 2 screws holding shaft plate to gas control body and

spindle, again noting its orientation.
f. Apply a suitable high temperature gas cock grease or
lubricant such as ROCOL - A.S.P (Anti scuffing paste) /
Dry Moly Paste to outside of spindle. (See Fig 10).
g. Replace spindle and re-assemble gas control valve in
reverse order.
h. Refit control panel and secure with 2 screws.
i. Refit knobs to gas control valve spindles.
