FLAME ADJUSTMENT

For fireplaces equipped with Hi/Lo valves, flame adjust-
ment is accomplished by rotating the Hi/Lo adjustment
knob located near the centre of the gas control. Fig. 71.
Turn
counterclockwise
to increase
flame height.

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. 72, 73 and 74). If any of the
flames appear abnormal call a service

INSPECTING THE VENTING SYSTEM

This appliance venting system was designed and con-
structed 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 door (See Glass Door Re-
moval). Using a flashlight, check the area above the baffle
in the combustion dome. Clean if necessary.
Turn clockwise
to lower
flame height.

MAINTENANCE

It is important to keep the burner and the burner compartment
clean. This must be done periodically, at least once per
season.
The optional FK24 fan does require periodic cleaning.
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.
Clean any optional brass trim using a soft cloth lightly
dampened with lemon oil. Do not use water or household
cleaners on any brass components.
Contact your local dealer to arrange an annual service
program.
CLEANING THE STANDING PILOT
CONTROL SYSTEM
The burner and control system consists of:
• main burners
• 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 side. (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 side.
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. 72.
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.
