FLAME CHARACTERISTICS

It is important to periodically perform a visual check of the pilot and the burner flames. Com- pare them to the pictorials illustrated below (Fig. 47, 48, 49, and 50). If any of the flames appear abnormal call a service person.

INSPECTING THE VENTING SYSTEM

This appliance venting system was designed and constructed to develop a positive flow adequate to remove flue gases to the outside atmosphere.

Any foreign objects in the venting system, except those designed specifically for the venting system, may cause spillage of flue gases.

To inspect the venting system, make sure the main gas valve is off. Remove glass frame (See Glass Frame Removal Section). Using a flashlight, check the area above the baffle in the combustion dome. Clean if necessary.

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 cleaners as these products will damage the brass trim. Lemon oil can be obtained at supermarkets or hardware stores.

3.The optional FK24 fan does require periodic clean- ing. Check the area under the control door and in front of the fan and wipe or vacuum at least once a month during the operating season.

4.Contact your local representative to arrange an annual service program.

CLEANING THE STANDING PILOT

CONTROL SYSTEM

The burner and control system consists of:

burner tube

gas orifices

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 side

2.Let fireplace cool if it has been running.

3.Remove glass. (see Glass Removal)

4.Remove logs.

LOGS MAY BE HOT

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 - see Operating Section of Manual.

8. Reinstall glass.

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. See Fig. 47.

To adjust pilot burner (by a Qualified Service Representative)

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 person.
