Cleaning the Standing

Pilot Control System

The burner and control system consist of:

• burner	• gas oriﬁce
• pilot assembly	• thermopile

•millivolt gas valve

Most of these components may require only an occasional checkup and cleaning and some may require adjustment. If repair is necessary, it should be performed by a qualiﬁed technician.

1.Turn off pilot light at gas valve.

2.Allow ﬁreplace to cool if it has been operating.

3.Remove window frame assembly. (Refer to Window Frame Assembly Removal section.)

4.Remove logs.

5.Vacuum burner compartment especially around oriﬁce primary air openings.

6.Visually inspect pilot. Brush or blow away any dust or lint accumulation.

7.Reinstall logs.

8.Ignite pilot - Refer to Lighting Instructions.

9.Reinstall window frame assembly.

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” to 1/2” of the thermopile should be engulfed in the pilot ﬂame. (Refer to Page 25, Figure 47)

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.
