Maintenance
Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the logs
and lava rock/ember material should be removed and
the burner compartment vacuumed and wiped out.
Remove and replace the logs as per the instructions in
this manual.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace 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
louvre 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
household cleaners on any brass components.
Contact your local representative to arrange an annual
service program.
General Maintenance
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
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 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 ” or 1 / 2 ” of the thermopile should
be engulfed in the pilot flame (Fig. 45, page 25).
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
technician.
