Pilot Flame Adjustment

Typically, the top 3/8” or 1/2” of the pilot flame sensor should be engulfed in the pilot flame. (Page 33, Fig. 55)

To adjust pilot burner:

1.Locate pilot adjustment screw on the valve next to the black plastic cap. Refer to Page 35.

2.Adjust pilot screw to provide proper sized flame. Only a small adjustment should be needed.

NOTE: Do not rotate screw excessively. Do not adjust any other screws on the valve.
