Cleaning and Maintenance

C

AUTION

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.

General

Clean the Cooktop regularly. A clean Cooktop 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: Each griddle option can be supplied with a scraper tool and a pack of blades for cleaning

the griddle surface. These are not supplied with the griddle and have to be purchased
separately. Refer to the 'Replacement Parts List' at the rear of this manual.

WARNING:

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

:

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 Cooktop.

• 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 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 Cooktop clean and operating at peak efficiency, follow the procedures shown below:-

After Each Use

1. Clean the griddle and cooktop castings with a scraper tool to remove any build up of carbon.

C

AUTION

Always ensure that an even pressure is applied over the whole surface of the
scraper tool when using on the flat surface of the griddle, to prevent scoring of
the surface.

NEVER bang the sharp edge of the scraper tool on the flat surface of the
griddle as this will damage the griddle and invalidate the warranty.

:

2. Always ensure that the 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 cooktop castings with a stiff nylon brush or a flexible spatula to remove any food debris.

19

Cleaning and Maintenance

Daily Cleaning

1. The grease / spill tray(s) should be checked and emptied frequently to prevent overflow and spillage.
