OPERATOR MAINTENANCE OPERATOR MAINTENANCE

USE ONLY SUITABL E CHEMICALS AND OBSERVE ALL
MANUFACTURER SAFETY REQUIREMENTS FOR SAFE
HANDLING AND USE.

SEASONING THE GRILL

NOTE: The grill surface has protective coating applied at manufacture.

Remove this by washing with hot water and a mild detergent until clean.

Season the grill by applying a thin coat of cooking oil with a cloth to the entire
grill surface. Remove any excess oil with a cloth.

Light the grill burner(s) and set at the lowest level (LEVEL 2). Operate the grill
for about 20 minutes and then wipe away the oil. Repeat this procedure three
times.

IMPORTANT: Only use low heat (LEVEL 2) when seasoning the grill.

NOTE: The grill surface will discolour from heat. Discolouring will not affect the

grill surface function and does not render the grill surface defective.

The grill surface should be cleaned with hot water and detergent.

Normally, if maintained properly, the grill will not need to be seasoned again. If
however, the grill has been overheated and product sticks to the grill surface, it
may be necessary to season the grill again.

Carbon and grease will affect the cooking performance and should be
removed as follows:

After each use, clean the grill thoroughly with a sharp grill scraper and wipe

off any excess debris.

NOTE: Empty the grease drawer as necessary and clean.

Weekly, clean the grill surface thoroughly with a grill pad while the surface is

Range Manual Page 18 Revision: 13 Sep 07
OPERATOR MANUAL 130907.doc

still warm (not hot). After cleaning, ensure any detergent/chemical is
thoroughly removed. The grill surface should be covered with a thin film of
cooking oil to prevent rusting.

Note: The grill plate is made of steel and can be easily scored or dented by

careless use of scrapers and spatulas.

CLEANING STAINLESS STEEL

Regularly wipe the surface with hot water and detergent. Rinse the washed
area with a wet sponge and clean water and wipe the area dry to prevent
streaking. Follow this process and wash a small area at a time to prevent
chemical residue and streaking.

Stainless steel may discolour if overheated. These stains can usually be
removed using an appropriate powder/paste. To scrape off heavy deposits of
grease and oil, use only wood or plastic tools as necessary.

Note: Never use steel wool to clean stainless steel.

Note: Damage may occur if chemicals not suitable for stainless steel are used.

OVEN INTERIOR (Enamel)

Note: Remove all oven racks and guides and clean these separately with a

suitable detergent and warm water.

The enamelled oven interior surface should be cleaned regularly with a
suitable oven cleaner.

OPEN TOP BURNERS

Note: Spillage is the major cause of problems to the performance of open top

and pilot burners. Spillage can block gas ports, which then causes burners to
operate inefficiently or, in bad cases, not at all. Clean any spillages as they
occur.

Note: The burner caps are enamelled – do not use abrasive cleaners.

To clean the burners, remove the burner cap and clean with a suitable
detergent and warm water. If the burner ports are blocked, clean these with a
stiff brush. Place the burner cap back on the burner, ignite and check that the
flame is even and comes from all ports (this dries the burner cap).

Range Manual Page 19 Revision: 13 Sep 07
OPERATOR MANUAL 130907.doc

If any ports remain clogged, remove the burner cap and complete burner and
clean thoroughly with a suitable detergent and hot water. Dry thoroughly,
ensure the air shutter is fully open, reinstall (ensure the injector is located in
the burner venturi), ignite and check the flame pattern.

Note: The burner flame should be uniformly blue. If yellow flames are present,

this may indicate that grease and dirt are present in the burner throat. Remove
and clean the burner per the above.

ENAMELLED TRIVETS

The enamelled trivets should be removed from the appliance before cleaning.

To clean the trivets, wash with warm water and a suitable detergent using a
soft cloth and then dry.

Note: Do not use abrasives pads or chemicals – these will damage the

enamelling.

For heavily soiled trivets, use a suitable oven cleaner and non-abrasive pad or
brush.
