Cleaning the Standing

Pilot Control System

The burner and control system consists of

burner tube gas orifice

pilot assembly thermopile

millivolt gas valve

Most of these components may require only an oc- casional checkup and cleaning and some may require adjustment. If repair is necessary, it should be per- formed by a qualified technician.

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. 89)

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.
