NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
The appliance is equipped with an outside
(make-up air) vent system that is designed to
provide the appliance with outside make-up
air for combustion when in operation. The
shut-off lever for the outside air system is
standard on all appliances but should not be
operated if the complete system is not in-
stalled. Refer to
Figure 5. Outside air kits are
not required in all municipalities and may not
be installed or active with your appliance.
If you have reason to believe that you do not
have a complete outside air system, contact
your distributor to have your appliance in-
spected for the presence of the complete
system. DO NOT assume that you have this
system in place.
The hand operated shut-off lever is located
in the right side of the fireplace opening
behind the screen. To open, lift and pull all
the way. The outside air damper should be
open when the fireplace is in use and com-
pletely closed when the fireplace is not be-
ing used. This will prevent outside cold air
from entering the dwelling.
Burner Adjustments
Flame Appearance and Sooting
Proper flame appearance is a matter of taste.
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large, or
with long vertical vent runs, will exhibit flames
that are blue and transparent. These weak, blue
and transparent flames are termed anemic.
If the air shutter opening is too small sooting
may develop. Sooting is indicated by black
puffs developing at the tips of very long orange
flames. Sooting results in black deposits form-
ing on the logs, appliance inside surfaces and
on exterior surfaces adjacent to the vent termi-
nation. Sooting is caused by incomplete com-
bustion in the flames and a lack of combustion
air entering the air shutter opening.
To achieve a warm yellow to orange flame with
an orange body that does not soot, the shutter
opening must be adjusted between these two
extremes.
No smoke or soot should be present. Reposi-
tion the log set if the flames impinge on any of
them.
If sooting conditions exist, the air shutter
opening on the main burner can be adjusted.
Normally, the more offsets in the vent system,
the greater the need for the air shutter to be
opened further.
MANUALLY-RESET BLOCKED FLUE SAFETY
SWITCH
This appliance is equipped with a manually-
reset blocked flue safety switch. Refer to
Figure 6 for its location. If during appliance
operation, the flame goes off (independently
of the burner on/off wall switch), it may be
due to the operation of this safety limit
switch. First allow the appliance to cool,
then reset the safety switch by pushing the
red reset button.
This reset button is located on the back of the
limit switch, between the wire terminals (
see
Detail A of Figure 6 ).
The appliance should then relight and remain
lit. If this does not occur, turn off the appli-
ance and call a qualified service technician.
Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. Proper maintenance and use will require
more frequent, less extensive inspections and
servicing by the homeowner.
Generally, annual inspections should be per-
formed by a qualified service technician. More
frequent periodic inspections and cleanings
should be performed by the homeowner. Any
discrepancies discovered by the homeowner
should result in a call to a qualified service
technician to effect the repair or correction.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by
whom they should be performed.
IMPORTANT: TURN OFF GAS AND ANY ELEC-
TRICAL POWER BEFORE SERVICING THE
APPLIANCE.
