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 installed. Refer to
not required in all municipalities and may not
be installed or active with your appliance.
If you have reason to believe that you do n ot
have a complete outside air system, contact
your distributor to have your appliance inspected 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 completely closed when the fireplace is not being used. This will prevent outside cold air

Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician. Proper maintenance and use will require
more frequent, less extensive inspections and
servicing by the homeowner.
Generally, annual inspections should be performed 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 maintenance tasks, procedures, periodicity and by
whom they should be performed.
IMPORTANT: TURN OFF GAS AND ANY ELECTRICAL POWER BEFORE SERVICING THE
APPLIANCE.
Burner Adjustments
Flame Appearance and Sooting
Figure 6
Detail A
Reset
Button
Wire
Terminals
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 forming on the logs, appliance inside surfaces and
on exterior surfaces adjacent to the vent termination. Sooting is caused by incomplete combustion 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. Reposition 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.

Adjustment
To adjust the flame, position the air shutter to
the nominal setting
(see Figure 7 ).
Allow the
burner to operate for at least 30 minutes.
Observe the flame continuously.
If it appears weak or sooty as previously described, adjust the air shutter open or closed
until desired effect is achieved.
Note: If the flame still appears anemic with the air
shutter closed all the way (usually a result of
lengthy vertical venting runs), turn off the appliance, turn off the gas supply, wait for the parts to
cool and access the air shutter. The shutter is
prevented from actually closing by a tab that is
bent over into the opening. Remove this obstruction by bending back. Reassemble and restart the
appliance and after 24 minutes reobserve the
flame. Adjust the air shutter as described.

TROUBLESHOOTING THE MILLIVOLT GAS CONTROL SYSTEM
Note: Before troubleshooting the gas control system, be sure external gas shut off valve (located at gas supply inlet) is in
the “ON” position.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
1. Spark ignitor will not light
pilot after repeated
triggering of ignitor button.
2. Pilot will not stay lit after
carefully following the
lighting instructions.
3. Pilot burning, no gas to
burner, Valve knob “ON,”
Wall Switch “ON.”
POSSIBLE CAUSES
A. Defective ignitor
(no spark at electrode).
B. Defective or misaligned electrode
at pilot (spark at electrode).
C. Gas supply pressure errant.
D. Pilot orifice plugged.
A. Defective pilot generator
(thermogenerator).
A. Damper closed or Damper Switch
defective.
CORRECTIVE ACTIONSYMPTOM
Check for spark at electrode and pilot; if no spark and
electrode wire is properly connected, replace ignitor.
Using a match, light pilot. If pilot lights, turn off pilot and
trigger the ignitor button again. If pilot lights, an improper
gas mixture caused the bad lighting and a longer purge
period is recommended. If pilot will not light – check gap at
electrode and pilot - should be 3/8" to have a strong spark. If
gap measures 3/8", replace pilot
Check inlet gas pressure. It should be within the limits as
marked on the rating plate.
Clean or replace pilot orifice.
Check pilot flame, it must impinge on thermogenerator
(Figure 9
mum flame impingement on thermogenerator. Ensure that
the connection between the valve and thermogenerator are
tight and secure.
Ensure damper control lever is locked in the open position,
all the way to the right. If the damper control lever is locked
in the open position troubleshoot through Steps B., C. and
D. below. If the main burner will still not light, determine if
the damper switch is defective and replace if necessary.

4. Frequent pilot/burner outage
problem.
B. Wall switch or wires defective.
C. Thermopile may not be generating
sufficient millivoltage.
D. Plugged burner orifice.
A. Pilot flame may be too low or
blowing (high) causing the pilot/
valve safety to drop out.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Check wall switch and wires for proper connections. Jumper
wire across terminals at wall switch, if burner comes on,
replace defective wall switch. If okay, jumper wires across
wall switch wires at valve, if burner comes on, wires are
faulty or connections are bad.
Check thermopile with millivolt meter. Take reading at thermopile terminals of gas valve. Should read 325 millivolts
minimum with optional wall switch “OFF.” Replace faulty
thermopile if reading is below specified minimum.
Check burner orifice for stoppage and remove.
Clean and/or adjust pilot flame for maximum flame impinge-
ment on thermogenerator
(Figure 9
on page 7).
