r6] CHECK IGNITION OF SURFACE
BURNERS
Operation of all cooktop and oven burners should be
checked after the range and gas supply lines have been
carefully checked for leaks.
Electric Ignition Models
Select a top burner knob and simultaneously push in
and turn to LITE position. You will hear a clicking sound
indicating proper operation of the spark module. Once the
air has been purged from the supply lines, burners should
light within 4 seconds. After burner lights, rotate knob out
of the LITE position. Try each burner in succession until all
burners have been checked.
Quality of Flames
The combustion quality of burner flames needs to be
determined visually.
(AI Yellow flames--
Call for service
(B) Yellow tips
on outer cones--
Normal for LP gas
(C) Soft blue
flames--Normal
for natural gas
If burner flames look like (A), call for service. Normal
burner flames should look like (B) or (C), depending on
the type of gas you use.
With LP gas, some yellow tipping on outer cones is
normal.

ADJUST BROIL AND OVEN BURNER
AIR ADJUSTMENT SHUTTERS IF
NECESSARY
Air adjustment shutters for the top and bottom burners
regulate the flow of air to the flames.
The air adjustment shutter for the top (broil) burner is in
the center of the rear wall of the oven.
adjustment
shutter
The shutter for the bottom (oven) burner is near the back
wall. See the Care and cleaning of the range section.
To adjust the flow of air to either burner, loosen the
Phillips head screw and rotate the shutter toward open or
closed position as needed.
The flames for the top (broil) burner should be steady with
approximately !" blue cones and should not extend out
over the edges of the burner baffle.
To determine if the bottom burner flames are burning
properly, remove the oven bottom and enclosure over
burner shutter for lower oven. Flames should have
approximately 1" blue cones and, if range is supplied
with natural gas, should burn with no yellow tipping.
(With most LP gas, small yellow tips at the end of outer
cones are normal.) Flames should not lift off burner ports.
If lifting is observed, gradually reduce air shutter opening
until flames are stabilized.
