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 asso-
ciated 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 air-
borne 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 com-
pletely 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 flut-
tering.
FLAME HEIGHT
• The correct flame height de-
pends 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 be-
yond 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,
the standard burners and
grill can be manually lit. It is
necessary 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 and grill burners
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
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 XLO, griddle, and wok
burners cannot be used during
a power failure.
• If you smell gas, refer to safety
precautions listed inside the
front cover.
Warning
In the event of a power fail-
ure, all knobs are to be
turned to the OFF Position.
Only the standard burners
can be lighted manually.
