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 Tips
of 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 1
″ 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 1/2
″ to 3/4″ 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.
Adjusting Orifice Hoods
Nat.
L.P.
Check the inner cones of the flames. 
The inner cones of the flames should be
about 1/2
″ long. If the flames are not
right, use a 1/2
″ 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 “L.P.” direction.
To lengthen the cones, loosen the
orifice hood by turning in the “Nat.”
direction.
