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 refit 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.
Cleaning the Control System
The burner and control system consist of:
burner tube gas orifice
pilot assembly 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 main gas shut-off 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” or 1/2” of the pilot flame sensor
should be engulfed in the pilot flame. (Page 28, Fig. 50)
To adjust pilot burner:
1. Locate pilot adjustment screw on the valve next to
the black plastic cap. (Refer to Page 30)
2. Adjust pilot screw to provide proper sized flame.
Only a small adjustment should be needed.
NOTE: Do not rotate screw excessively. Do not adjust
any other screws on the valve.
