f.If pressure drop is still greater than 1/2" W.C., there may be a lack of volume due to too small of a supply line. Check with the gas provider about installing a larger size gas line.

WARNING: All gas joints disturbed during servicing must be checked for leaks. Do not use an open flame. Use a hazardous gas tester or a soap and water solution (Bubbles indicate a gas leak). Failure to comply can cause property damage, injury or death.

Oven Pilot Flame Check and Adjustment

The pilot flame should be:

A.Large enough to completely engulf the tip of the thermocouple/sensor and make the tip of the thermocouple/sensor red hot.

B.A sharp, well-defined two-tone blue flame when burning natural gas.

NOTE: when burning propane (LP), there may be a tiny yellow tip to the flame. This yellow tip should be no more than 10% of the total flame size.

To adjust the pilot flame:

CAUTION: Do not back the pilot adjustment screw out too far. It might become loose and/or fall out and cause a gas leak.

1.Perform the MANIFOLD COVER removal procedure.

2.Locate the pilot adjustment screw.

3.Rotate the screw clockwise to decrease and counterclockwise to increase the flame height.

4.Reinstall the MANIFOLD COVER.
