ALIGNMENTS AND ADJUSTMENT, Continued
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 1/2 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.
ALIGNMENTS AND ADJUSTMENT, Continued
In the event of a power failure, the top burners can be lit by holding a lighted match near
the burner head and turning the appropriate top burner knob to the “LITE” position.
Top Burner Height
Make sure the top burners are properly positioned. The top of the burner head should be
level with the surface of the main top. To check, lay a straight edge such as a 12-inch
ruler across the burner bowl opening. The ruler should rest squarely on the top while in
contact with the burner head.
If the burner is too high (make sure the burner is cool), push it down. Supply enough
force with the palm of you hand to accomplish this adjustment. To raise, pull up on the
burner support at the center of the support.
5. Oven Control (Thermostat)
The oven control has a flame safety device built into the body of the thermostat.
Presence of a gas ignition source (pilot) is verified by a flame safety probe. This flame
safety probe actuates the internal safety device to allow gas into the oven burner when the
oven is turned on. If there is a loss of gas ignition during operation, the flame safety
device will close off gas flow to the oven burner and pilot.
The oven burner orifice is located on a brass injector stud at the rear of the oven under the
oven floor. This orifice is dedicated to the gas for which the oven is to be used. The
orifice is not adjustable. It must be changed completely to convert from one gas to the
other. DO NOT DISCARD THE UNUSED ORIFICE. It should be saved in order to
convert the range back to its original fuel.
When converting the oven thermostat to LP (Propane) gas, the minimum bypass screw
must be screwed in all the way until it tightens. To convert back to natural gas, turn the
screw counterclockwise until the minimum burner flames appear as a row of 1/8”
diameter dots along the side of the burner.
3/4” FLAME HEIGHT
ON “HIGH” SETTING
Note: “Full on” flame size illustrated.
The flame height in the “Low” position
should be approximately 1/8” high.
