Burner and Burner Compartment
It is important to keep the burner and the burner com-
partment clean. At least once per year remove the logs
and lava rock/ember material. Vacuum and wipe out the
burner compartment. Remove and refit the logs per the
instructions in this manual.
Always handle the logs with care as they
are fragile and may also be hot if the fire-
place has been in use.
FK24/FK12 Fan Assembly
The fan unit requires periodic cleaning. At least once
per month in the operating season, open the lower lou-
vre panels and wipe or vacuum the area around the fan
to remove any build up of dust or lint.
Brass Trim
Clean the brass trim pieces using a soft cloth lightly
dampened with lemon oil. Do not use water or house-
hold cleaners on any brass components.
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 occa-
sional checkup and cleaning and some may require ad-
justment. 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 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.
Maintenance
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 – 1/2” (10 – 13 mm) of the thermo-
pile should be engulfed in the pilot flame. (Page 26, Fig.
46)
To adjust pilot burner (to be done by a 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 be
adjusted, if necessary, only by a qualified service tech-
nician.
Cleaning Electronic Ignition System
The Electronic Ignition burner/control system consists
of:
• main burner
• gas orifice
• pilot burner
• 24VAC valve with transformer
The process for taking care of Electronic Ignition units is
identical to that for taking care of Standing Pilot models.
