To obtain proper operation, it is imperative that the pilot
and burner’s flame characteristics are steady, not lifting
or floating.
Typically, the top 3/8” or 1/2” of the thermopile should
be engulfed in the pilot flame. (Fig. 21)
To adjust pilot burner; (by qualified service technician)
1. Remove pilot adjustment cap.
2. Adjust pilot screw to provide properly sized flame.
3. Replace pilot adjustment cap.
The primary air shutter is set at factory and should only
be adjusted, if necessary, by a qualified service techni-
cian.
