Operation
About the Appliance When a flame is present and a Low setting is used, the
igniter may occasionally spark. This is normal.
Use the cooktop for surface cooking applications such as
boiling, frying, simmering, steaming and sauteing.
In the Event of a Power Failure
Operation
WARNING:
The burning of gas cooking fuel can create
small amounts of Carbon Monoxide, Benzene,
Formaldehyde and Soot. To minimize exposure
to these substances, the burners should be
adjusted by a certified installer or agency to
ensure proper combustion. Ensure proper
ventilation with an open window or use a
ventilation fan or hood when cooking with Gas.
Always operate the unit according to the
instructions in this manual.
The cooktop has one control knob for each burner. Push
down and turn to the desired heat setting.
Normal Operation (Electronic Ignition/
Reignition)
The cooktop uses electronic igniters to light the burners.
There is no pilot light. Each burner has its own igniter. If a
burner flame blows out during use, the burner will
automatically reignite.
,_ CAUTION:
Do not touch any of the burners when the
-- cooktop is in use. All ignitors spark when any
single burner is turned ON or the reignition
system is activated.
The ignitor should be clean and dry for proper operation.
Avoid getting water or food on the igniter.
If the igniter is wet or soiled, it may spark without
igniting the burner, or even spark continuously when a
flame is present.
In the event of a power failure, the burners can be ignited
manually. If the cooktop is being used when a power failure
occurs, turn all the burner control knobs to the OFF
position. The burners can then be ignited manually by
holding a match at the ports and turning the control knob to
the HI position. Wait until the flame is burning all the way
around the burner before adjusting the flame to the desired
height.
_L, WARNING:
The reignition feature will not work in the event
of a power failure.
Typical Flame Characteristics
The burner flame should be blue in color and stable with no
yellow tips, excessive noise or fluttering. It should burn
completely around the burner cap.
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or
mostly yellow, verify that the
regulator is set for the correct fuel. After adjustment,
retest.
Some yellow streaking is normal during the initial start-
up. Allow unit to operate 4-5 minutes and re-evaluate
before making adjustments.
Figure 10: Checking Flame Characteristics
NOTE:
If the burner does not light within 4 seconds, turn the burner
off. Check to see that the cap is positioned correctly on the
burner base and the igniter is clean and dry. If a burner still
fails to ignite, see "Before Calling for Service" on page 14.
Foreign particles in the gas line may cause an orange
flame during initial use. This should disappear with use.
Check burner to make sure port holes are not obstructed. If
the ports are clogged, see "Before Calling for Service" on
page 14.
