AND MAINTENANCE  
General Information  
The fireplace models covered in this manual  
aredirect-ventsealedcombustiongasfireplace  
heaters designed for residential application.  
These direct-vent appliances operate with the  
combustion chamber completely isolated from  
the indoor environment.  
IMPORTANT: Improper installation,  
adjustment, alteration, service, or  
maintenance can cause injury or  
property damage. Refer to this manual.  
For assistance or additional information,  
consult a qualified installer, service  
agency or the gas supplier.

manufacturer shall be used in the  
installation of this appliance.  
Do not use this appliance if any part has  
been under water. Immediately call a  
qualified service technician to inspect the  
appliance and to replace any part of the  
control system and any gas control that  
has been under water.  
These appliances are designed to operate on  
natural or propane gas. An electronic intermit-  
tent pilot ignition system provides safe, efficient  
operation. External electrical power is recom-  
mended to operate these units. If the system  
operates on line voltage with 6V fan control  
module, four (4) "AA" batteries can be used as a  
backupincaseofapoweroutage. Theelectronic  
appliance can be operated solely with four (4)  
"AA" batteries.

anceandSootingonPage17. TheHomeowner  
must contact a qualified service technician at  
once if any abnormal condition is observed.  
Inspect Venting System  
Clean Control Compartment  
The appliance and venting system should be  
thoroughly inspected before initial use and  
at least annually by a qualified service techni-  
cian (inspection should include ensuring that  
exhaust or intake passages are unobstructed  
and vent components are properly assembled  
and not damaged). Homeowner must contact  
a qualified service technician at once if any  
abnormal condition is observed.  
Keepcontrolcompartmentcleanbyvacuuming  
or brushing at least twice a year. More frequent  
cleaning may be required due to excessive lint  
from carpeting, bedding materials, etc. It is  
important that control compartments, burners  
andcirculatingairpassagewaysoftheappliance  
be kept clean.  
Small Area Paint Touch-up  
The finish of the appliance is a high-qual-  
ity powdercoat. Only use factory supplied  
powdercoat paint kit for touch-ups. Paint  
is available at your local authorized Lennox  
Hearth Products dealer. Never attempt to

Clean Logs And Burner  
If the venting system is disassembled for any  
reason, a qualified service technician should  
follow vent installation instructions for proper  
reassembly and proper sealing of the venting  
system components. However, more frequent  
periodic inspections and cleanings should be  
performed by the homeowner.  
Carefully remove the logs (use care when han-  
dlingthefiberlogs,astheybecomequitefragile  
after curing). Vacuum out any foreign matter  
(lint, carbon, etc.) on the burner. Ensure the  
burner ports are “open.” Remove any carbon  
deposits from the under side of the logs using  
a vacuum cleaner, or a soft bristled brush (i.e.  
paint brush).

Step 1. Follow the log placement instructions exactly. Refer to Figures  
11, 12 and 13 for detailed log placement instructions.  
Step 2. Separate the Glowing Ember (Rockwool) into pieces about the  
size of a nickel (see Figure 9 ). Keep the pieces fluffed up with torn edges  
and not matted. Distribute these pieces over the burner as shown in  
Figure 10. Do not use more than necessary. When properly positioned,  
the Glowing Embers may cover the entire burner in front of the front  
ports. Do not place embers on main ports in front of the rear log.  
WARNING  
• DO NOT attempt to install the logs until the  
appliance installation has been completed, the  
gas line connected and tested for leaks and the  
initial burner operation has been checked out.  
• The size and position of the log set was engi-  
neered to give the appliance a safe, reliable  
and attractive flame pattern. Any attempt to use  
a different log set in the fireplace will void the  
warranty and will result in incomplete combus-  
tion, sooting, and poor flame quality.  
Note: Position andirons and secure to the sub-floor before placing  
volcanic stone and vermiculite.  
• Logs get very hot and will remain hot up to one  
hour after gas supply is turned off. Handle only  
when logs are cool. Turn off all electricity to  
the appliance before you install grate, volcanic  
stone, vermiculite, embers and logs.

BURNER ADjUSTMENTS  
(QUALIFIED TECHNICIANS ONLY)  
Flame Appearance and sooting  
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  
graduallyturnyellowish-orangeduringthefirst  
15 minutes of operation. If after a short period  
the flame stays lowered blue, or if the flame is  
orange with evidence of sooting (black tip), the  
air shutter opening may need to be adjusted.  
Iftheairshutteropeningsclosedtoofar,sooting  
maydevelop. Sootingisindicatedbyblackpuffs  
developingatthetipsofverylongorangeflames.  
Sootingresultsinblackdepositsformingonthe  
logs, appliance inside surfaces and on exterior  
surfaces adjacent to the vent termination.  
Figure 14  
SYM-35  
Sooting is caused by incomplete combustion in  
the flames and lack of combustion air entering  
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.  
Air Shutter Adjustment Guidelines  
• 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.  
Figure 15  
SYM-40  
• Propane models may exhibit flames which  
candle or appear stringy. If this is present and  
persists, adjust the air shutter to a more open  
position, then operate the appliance for a few  
moreminutestoensurethattheflamenormal-  
izes and the flames do not appear sooty.  
The following chart is provided to aid you in  
achieving the correct air shutter adjustment  
for your installation.
