CAUTION:
DO NOT touch the STAR burners when the igniters are
sparking. Ensure that the knobs are set to OFF and the
burners and caps have cooled before touching.
If a burner fails to ignite, refer to "Before Calling For
Service" on page 39.
Automatic Re=Ignition
If any one or more burners blow out, the electronic igniter
automatically activates to re-light the flame. DO NOT touch
the STAR burners when the igniters are active.
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 normal.
• On cooktops using propane (LP) gas, a slight "pop"
sound may be heard from the STAR burner ports a few
seconds after the burner has been turned off.
Power Failure
• In the event of a power failure, only the Standard
burners can be manually lit. It is necessary to light each
one individually.
• If the rangetop is being used when the power failure
occurs, turn all knobs to the OFF position.
• The standard STAR burners can be lit 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 before adjusting the flame to the
desired level.
• DO NOT attempt to light the two left or two right XLO ®
burners manually during a power failure. These
burners are equipped with the ExtraLow ® feature and
cannot be lit manually.
• If an ExtraLow burner is on when a power failure
occurs, it cannot be turned back on until the knob is
first turned to the OFF position.
• The griddle or grill accessory cannot be used during a
power failure.
• If you smell gas, refer to safety precautions listed on
page 1.
WARNING:
In the event of a power failure, turn all knobs to the OFF
position. Only the standard burners can be lit manually.
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.
Flame Description
-- Dark Blue
-- Secondary Cone
-- Light Blue
-- Primary Cone
Figure 17: Flame Colors
• The burner flame color should be blue with no yellow
on the tips. It is common to see orange in the flame
color; this indicates the burning of airborne impurities
and will disappear with use
• With propane (LP) gas, slight yellow tips on the
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.
