Care and cleaning of the oven.
Air adjustment shutters for the broil and
oven burners regulate the flow of air to
the flame.
All ovens are factory adjusted for use
with the natural gas used in most areas.
But, since the gas in some areas may be
different, you should check all adjustments
described. If you are using LP gas, all the
adjustments must be made.
The air adjustment shutter for the top
burner is in the center of the rear wall of the
oven.
The shutter for the bottom burner is near
the back wall. Remove the oven bottom for
access.
Turn the burner full on and check the
flames. The burner flames should not flutter
or blow away from the burner. They should
be blue in color with no trace of yellow.
Foreign particles in the gas line may cause
an orange flame at first, but this will soon
disappear. If the flames are yellow or flutter,
open the air shutter more. If they blow away
from the burner, close the air shutter more.
See the illustration in the Troubleshooting
Tipsof this guide for correct flame
appearance.
To adjust the flow of air to either burner,
loosen the Phillips head screw and rotate
the shutter to allow more or less air into the
burner tube as needed.
The flames for the top (broil) burner should
burn steady with approximately 1s blue
cones and should not extend out over the
edges of the burner baffle.
To determine if the bottom burner flames
are proper, remove the oven bottom and
the burner baffle. The flames should have
1/2s to 3/4s blue cones with no yellow
tipping. When the baffle is back in place, the
flames will resettle.
Visually check the color of the flames every 6
months. If they look like illustration (A) in the
Troubleshooting Tips
in this guide, call for service.
When checking the flames, before and
after adjustments, the oven door should
be closed.

Check the inner cones of the flames. The
inner cones of the flames should be about
1/2s long. If the flames are not right, use a
1/2s open-end wrench or adjustable joint
pliers to adjust the orifice hood.
WARNING:
If you attempt to
measure the inner cone of the flame, please
use caution. Burns could result.
To shorten the cones, tighten the orifice
hood by turning in the “LP” direction. To
lengthen the cones, loosen the orifice hood
by turning in the “Nat” direction.
