2. Gas System Operating Characteristics
Cooking on your new gas range may differ slightly than on previous ranges because of a
new system designed to better regulate temperature control. Most ovens have a burner
that cycles on then off to maintain an average temperature. Gas ranges with standing
pilot ignition have a revolutionary thermostat that continually adjusts gas flow to hold a
constant temperature without completely shutting off the burner. As seen in the figures
below, the result is an oven temperature that remains steady throughout the entire
cooking period.
•
Your gas range is set from the factory for natural gas or has the hardware necessary
to covert to LP (Propane) gas.
3. Top Pilots (Gas)
The top burner pilots can be adjusted by a screw located on the pilot filter attached on the
rear face of the manifold pipe. Adjust the pilot flame until there is only a slight tip of
yellow on the flame. Pilots are constant burning. DO NOT BLOW OUT FLAME
WITHOUT TURNING OFF PILOT ADJUSTMENT SCREW.

4. Top Burner Valves
Top burner valves have orifices that are dedicated to the type of fuel to be used. These
orifices are not adjustable. They must be changed completely to convert from one gas to
the other. DO NOT DISCARD THE UNUSED ORIFICES. They should be saved in
order to convert the range back to its original fuel.
When converting the gas valves, the minimum flame adjustment screw must be adjusted
through the center of the valve stem. You will need a 3/32” flat blade screw driver to
make this adjustment. Hold the valve stem and turn the adjustment screw until the proper
flame of approximately 1/8” is obtained.
Adjust the air shutter, which is located on the throat of each burner, to obtain the proper
mixture of gas and air to create the proper sharp blue flame without a red or yellow tip.
The properly adjusted flame is approximately 3/4" high and has three distinct cones; the
kindling point, the dark blue center cone, and the outer mantel.
Standard Top Burner Valves
All top burner valves operate counterclockwise to open the valve and clockwise to close
the valve. To ignite gas, depress and turn the valve knob 90 degrees to the left to the
“LITE” position. You will feel a detent in the knob. This position is also the “HI”
position where the maximum gas flow rate is obtained, and the burner should light
automatically from the pilot flame. By turning the top burner knob past the “HI”
position, the valve can be adjusted to many different heat settings which should be
determined by the amount of food being cooked, the amount of liquid, or the size of the
utensil.
Top Burners with Pilotless Electric Spark Ignition
Ranges equipped with electric ignition will have the top ignitor electrodes in the same
location as the familiar top burner standing pilots except for sealed burner models that
employ an ignitor for each burner. (See page 13 in the Owner’s Manual.) To ignite the
burner, depress and turn the valve knob 90 degrees to the left to the “LITE” position.
When a top burner knob is pressed, ALL electrodes will spark at a rate of approximately
2 _ pulses (sparks) per second. Continue to hold the knob depressed until gas ignites at
the burner. Adjust the intensity of top burner heat in the same manner described above.
