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.
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
Fig. 47
month during the operating season.
4. Contact your local representative to arrange an
annual service program.
CLEANING THE STANDING PILOT
The burner and control system consists of:
• burner tube
Fig. 48
• pilot assembly
• 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)
Fig. 48
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 - 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.
