TOP BURNER ORIFICES
The top burner orifices each have a series of marks engraved on the
tops of the orifices (I, II, III) to denote their location. The marks
appear on both the Natural and LP gas orifices. The location
indicated by the marks, is the same for both gases.
See BURNER OUTPUT RATING charts at right for locations.

Open the bake and broil air shutter adjustments as far as possible and adjust later if necessary.
Beneath the bake and broil burner orifice hoods are LP orifice needles. To convert to L.P. tighten the orifice hoods
against the orifice needle until the hoods are snug (2-2½ turns). DO NOT OVER TIGHTEN. Check the burners for
proper flame adjustment. The burner flame should have approximately 1" blue cones. 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 the air shutter opening until flames are stabilized.
