Maintenance
1.It is important to keep the burner and the burner compartment clean. This must be done periodically, at least once per season.
2.Clean the brass trim using a soft clean cloth, slightly dampened with lemon oil and buff with a soft clean cloth. DO NOT use brass polish or household clean- ers as these products will damage the brass trim. Lemon oil can be obtained at supermarkets or hard- ware stores.
3.Periodically check and clean the air circulating blower wheel of any debris. Blower motors are prelubricated for extended bearing life. No further lubrication is required. WARNING: Disconnect power before servicing the air circulating blower.
4.The air filter should be inspected monthly and re- placed when necessary with a 16" x 16" x 1" filter.
5.When servicing, check all electrical wiring for loose connections.
WARNING: Disconnect power before serv- icing.
6.Contact your local representative to arrange an an- nual service program.
Cleaning the Standing
Pilot Control System
The burner and control system consist of:
• burner tube | • 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” (10mm or 13mm) of the thermopile should be engulfed in the pilot flame. (Refer to Page 21, Figure 40)
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 technician.
