• During start-up, it is normal for condensa-  
tion to form on the inside of the glass (this  
condensation and fog will usually disappear  
in a few minutes). The moisture can cause  
lint,dustandotherairborneparticlestocling  
to the glass surface.  
• Initial curing of the high temperature paint  
and burning off of lubricants used in the  
manufacturing process may result in a film  
on the glass.  
Carefully follow placement instructions on  
Pages 12 through 14. All logs should fit  
onto corresponding pins and/or log stop-  
pers. This will ensure a proper flame and  
safe combustion.

Air Shutter Adjustment Guidelines  
The following chart is provided to aid you in  
achieving the correct air shutter adjustment  
for your installation.  
BURNER ADjUSTMENTS  
(QUALIFIED TECHNICIANS ONLY)  
• If there is smoke or soot present, first  
check the log set positioning to ensure that  
the flames are not impinging on any of the  
logs. If the log set is properly positioned  
and a sooting condition still exists, then the  
air shutter opening should be increased.  
• Themoreoffsetsintheventsystem,thelarger  
the air shutter opening will need to be.  
• An appliance operated with the air shutter  
opened too far, may have flames that appear  
blue and transparent. These weak, blue and  
transparent flames are termed anemic.  
• Propane models may exhibit flames which  
candle or appear stringy. If this is present  
and persists, adjust the air shutter to a more  
closed position, then operate the appliance  
for a few more minutes to ensure that the  
flame normalizes and the flames do not  
appear sooty.  
Flame Appearance and Sooting  
Air Shutter Adjustment Guidelines:  
Proper flame appearance is a flame which is  
blueatthebaseandbecomesyellowish-orange  
in the body of the flame.

When the appliance is first lit, the entire flame  
may be blue and will gradually turn yellowish-  
orangeduringtherst15minutesofoperation.  
If the flame remains blue, or if the flame is  
orange with evidence of sooting (black tip), the  
air shutter opening may need to be adjusted.  
If air shutter is  
open too far  
Flame will Air shutter  
be blue gap should be  
decreased  
If the air shutter opening is closed too far,  
sooting may develop. Sooting is indicated by  
black puffs developing at the tips of very long  
orangeames. Sootingresultsinblackdeposits  
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 lack of combustion air enter-  
ing the air shutter opening. To achieve a warm  
yellowish-orange flame with an orange body  
that does not soot, the shutter opening must be  
adjusted between these two extremes.

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.  
POSSIBLE CAUSES

CORRECTIVE ACTION  
1. Spark ignitor will not light  
pilot after repeated triggering  
of ignitor button.  
Checkforsparkatelectrodeandpilot;ifnosparkandelectrode  
wire is properly connected, replace ignitor.  
A. Defective ignitor  
(no spark at electrode).  
Using a match, light pilot. If pilot lights, turn off pilot and trig-  
ger the ignitor button again. If pilot lights, an improper gas  
mixture caused the bad lighting and a longer purge period is  
recommended.Ifpilotwillnotlightcheckgapatelectrodeand  
pilot – should be 1/8" to have a strong spark. If gap measures  
1/8", replace pilot (Figure 15 on page 16).  
B. Defective or misaligned electrode  
at pilot (spark at electrode).  
C. Gas supply pressure errant.  
Check inlet gas pressure. It should be within the limits as  
marked on the rating plate.  
D. Pilot orifice plugged.  
Clean or replace pilot orifice.  
Check pilot flame, it must impinge on thermocouple (Figure  
15 on page 16) Clean and/or adjust pilot for maximum flame  
impingement on thermocouple. Ensure that the connection  
between the valve and thermocouple are tight and secure.  
2. Pilot will not stay lit after  
carefully following the light-  
ing instructions.  
A. Defective pilot generator  
(thermocouple).  
3. Pilot burning, no gas to  
burner, Valve knob “ON,”  
Wall Switch “ON.”  
A. Wall switch or wires defective.  
Check wall switch and wires for proper connections. Jumper  
wire across terminals at wall switch, if burner comes on, re-  
place 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 thermo-  
pileterminalsofgasvalve.Shouldread325millivoltsminimum  
with optional wall switch “OFF.” Replace faulty thermopile if  
reading is below specified minimum.  
B. Thermopile may not be generating  
sufficient millivoltage.  
C. Plugged burner orifice.  
Check burner orifice for stoppage and remove.  
Clean and/or adjust pilot flame for maximum flame impinge-  
ment on thermocouple (Figure 15 on page 16).
