AUTOMATIC RE-IGNITION
If any one or more burners or grill
blow out, the electronic igniter
automatically sparks to re-light the
flame. Do not touch the burners
when the igniters are sparking.
IMPORTANT:
• For proper combustion do not use
the cooktop without the burner
grates in place.
• There is a slight sound associated
with gas combustion and ignition.
This is a normal condition.
• On cooktops using propane gas
(LP), a slight “pop” sound may be
heard at the burner ports a few
seconds after the burner has been
turned off.
FLAME DESCRIPTION
• The burner flame color should be
blue with no yellow on the tips. It
is not uncommon to see orange
in the flame color; this indicates
the burning of airborne impurities
in the gas and will disappear with
use.
• With propane (LP) gas, slight
yellow tips on the primary cone
are normal.
• The flame should burn completely
around the burner cap. If it doesn’t,
check that the cap is positioned
correctly on the base and that the
ports are not blocked.
• The flame should be stable with
no excessive noise or fluttering.
FLAME HEIGHT
• The correct flame height depends
on 1) size and material of pan
being used; 2) food being cooked;
and 3) amount of liquid in the pan.
• Never extend the flame beyond
the base of the pan.
• Use a low or medium flame for
pan materials that conduct the
heat slowly, such as porcelain
coated steel or glass-ceramic.
POWER FAILURE
• In the event of a power failure,
only the standard burners and
grill can be manually lit. It is
necessar y to light each one
individually.
• If the cooktop is being used when
the power failure occurs, turn all
knobs to the OFF position.
• The standard burners and grill can
be lighted by holding a match at
the ports and turning the control
knob to the HI position. Wait until
the flame is burning all around the
burner cap or U-shaped burner
before adjusting the flame to the
desired height.
• Neither ExtraLow burner can be
used during a power failure. Be
sure to turn them off.
• If either ExtraLow burner is on
when a power failure occurs, they
cannot be turned back on until
both knobs are first turned off.
• The griddle cannot be used during
a power failure.
• If you smell gas, refer to safety
precautions listed inside the front
cover.
