2. Always ensure that scraper tool blades are changed regularly to ensure that the scraper tool works efficiently and prevents damage to the griddle plate surface.
3. Clean the range castings with a stiff nylon brush or a flexible spatula to remove any food debris.
Daily Cleaning
1. The grease / spill tray(s) should be checked and emptied frequently to prevent overflow and spillage. Remove the spill tray(s) while still warm so that the grease is in a liquid state. Empty any grease from the trays and wash the trays thoroughly in the same manner as any cooking utensil.
2. Clean the control panel with a damp cloth lightly moistened with a solution of mild detergent and water. Wipe dry with a clean dry cloth.
3. Remove the burner caps, bases, the trivets and thoroughly clean including the splash back, interior and exterior surfaces of the range with hot water, a detergent solution and a soft scrubbing brush.
4. Brush the griddle surface (optional - if fitted) 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.
5. Dry the Range thoroughly with a dry cloth and polish with a soft dry cloth.
Weekly Cleaning
NOTE:
 If the Range usage is very high, we recommend
that the weekly cleaning procedure is carried out on a more frequent basis.
 Ensure that protective gloves are worn during the
cleaning process.
 DO NOT use harsh abrasive or caustic detergents
or strong solvents as they will damage the cooktop, burners and griddle plates (if fitted).
 DO NOT use water on the trivets, griddle plates
and burners while they are still hot as cracking may occur. Allow these items castings to cool and remove for cleaning.
 DO NOT clean the burners in a dishwasher.
General
General
Clean the Range regularly. A clean Range looks better, will last longer and will perform better. Carbonised grease on the surface or between the trivets, griddle plates will hinder the transfer of heat from the cooking surface to the food. This will result in loss of cooking efficiency.
NOTE: NEVER use a ribbed scraper blade on the flat surfaced griddle plate.
DO NOT use water on the trivets, burners and griddle plates while these items are still hot as warping and cracking may occur. Allow these items to cool down and then remove for cleaning. The entire
trivets, griddle plates and burner caps can be dismantled for cleaning.
NOTE:
 DO NOT use abrasive detergents, strong solvents
or caustic detergents as they could corrode or damage the Range.
 In order to prevent the forming of rust on the
trivets, griddle plate (If fitted) and burners, ensure that any detergent or cleaning material has been completely removed after each cleaning. The appliance should be switched 'On' briefly to ensure that the griddle plates become dry. Oil or grease should be spread over the griddle surface in order to form a thin protective greasy film.
To keep your Range clean and operating at peak efficiency, follow the procedures shown:-
After Each Use
1. Clean the Griddle and Range castings using a scraper tool to remove any build up of carbon.
C
AUTION
:
Always turn off the gas supply at the mains supply before cleaning. This appliance is not water proof. Do not use water jet spray to clean interior or exterior of this appliance.
