7. Electric Ignition Surface Burners
Operation of electric igniters should be checked after range
and supply line connectors have been carefully checked for
leaks and range has been connected to electric power.
a. To check for proper lighting, push in and turn a surface
burner knob counterclockwise to the LITE position. You
will hear the igniter sparking (See Fig. 1).
b,
The surface burner should light when gas is available to
the top burner. Purge air from supply lines by leaving knob
in the LITE position until burner ignites. Each burner
should light within four (4) seconds in normal operation
after air has been purged from supply lines.
c. Visually check that burner has lit. Once the burner lights,
the control knob should be turned out of the LITE position.
Test to verify if "LOW" setting should be adjusted
a. Push in and turn control to LITE until burner ignites.
b. Push in and quickly turn knob to LOWEST POSITION.
c. If burner goes out, reset control to OFF.
d. Remove the surface burner control knob.
e. Insert a thin-bladed screwdriver into the hollowvalve stem
and engage the slotted screw inside. Flame size can be
increased or decreased with the turn of the screw. Turn
counterclockwise to increase flame size. Turn clockwise

Operation of electric igniters should be checked after range
and supply line connectors have been carefully checked for
leaks and range has been connected to electric power.
The oven burner is equipped with an electric control system as
well as an electric oven burner igniter. If your model is equipped
with a waist-high broil burner, it will also have an electric burner
igniter. These control systems require no adjustment. When
the oven is set to operate, current will flow to the igniter. It will
"glow" similar to a light bulb. When the igniter has reached a
temperature sufficient to ig nite gas, the electrically controlled
oven valve will open and flame will appear at the oven burner.
There is a time lapse from 30 to 60 seconds after the
thermostat is turned ON before the flame appears at the oven
burner. When the oven reaches the dial setting, the glowing
igniter will go off. The burner flame will go "out" in 20 to 30
seconds after the igniter goes "OFF." To maintain any given
oven temperature, this cycle will continue as long as the dial
(or display) is set to operate.
After removing all packing materials and literature from the
oven:
a) Set oven to BAKE at 300°F. See Use & Care Guide for
operating instructions.
b) Within 60 seconds the oven burner should ignite. Check
for properflame, and allowthe burner to cycle once. Reset
controls to off.
c) Ifyourmodel is equipped with awaist-high broiler, setoven
to BROIL. See Use & Care Guide foroperating instructions.
d) Within 60 seconds the broil burner should ignite. Check
for proper flame. Reset controls to off.
