OPERATING INSTRUCTIONS
Page 10 62.9540.01_UL
D Wash the appliance panels using hot water to which a fat-
dissolving agent has been added, dry and polish if neces-
sary. No steel brushes, steel or copper wool or similar
utensils are to be used.
2.1 FINNED PAN RESTS
Use a sponge and lukewarm soapy water or another soft
detergent for cleaning. Do not use steel wool or abrasive
cleaning agents so as not to damage the enamel. If heavily
soiled, the pan rests should be soaked in soapy water over-
night.
Finned pan rests made of chrome nickel steel can be washed
in a washing machine.
2.2 HOTPLATE
From time to time use a steel brush to clean dirt and soot from
the plate and grease it lightly with commercial range plate
grease. Never use water for cleaning, as this would cause cor-
rosion.
2.3 BURNER
D Lift off the burner lid (1 / Fig. 11) and pilot burner body (3 /
Fig. 11).
D Soak overnight in soapy water.
D Clean thoroughly with a brush.
D Clean blocked holes (2 / Fig. 11) on the burner cover (1 /
Fig. 11) and holes in the pilot burner (7 / Fig. 11), blow
through if necessary.
D Do not use abrasive paper to clean the tip of the thermo-
element (7 / Fig. 11). The sensor must be free of cracks.
D Take great care that no dirt enters the gas supply line
(burner tube (4 / Fig. 11) and the pilot burner opening).
Cover these places if necessary.
D Thoroughly dry all the burner parts before reinstalling them.
Note:
• The burner lid (1 / Fig. 11) must lie evenly and engage in
the burner body which must engage in the burner tube.
• Ensure the correct positioning of the burner lid before light-
ing the burner. It must be fixed and only movable in the ver-
tical position.
CAUTION:
Wrong positioning of the burner lid can cause combustion
irregularities - danger of burning!
2.4 FLAME
In a visual check, the flames must be dark blue without any
upper yellow or orange tips; they must be stable and soot-free
and adhere firmly to the outlets.
If there is a lack of primary air, the flame has yellow streaks
and tips; if there is too much primary air, the flame is short,
transparent and tends to lift off the burner.
When the flame is correctly adjusted, it must not lift off or back-
fire when the burner is cold as well as warm.
The flame will backfire into the inside of the burner when the
speed of the gas-air mixture through the burner outlets is too
low, particularly when the air passages are dirty.
The different ignition processes must also take place without
any delays. This concerns: ignition, arc-through and extending
the flame over the whole burner area.
If the flame fails to meet all the requirements, cleaning or main-
tenance is necessary.
