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.

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.
