FDVS
• 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.
• 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.
Figure 5
• This appliance is not designed to burn wood.
Any attempt to do so could cause irreparable
damage to the appliance and prove hazardous
to your safety.
For Propane Gas Only, Do Not Place Embers On Main Ports
• If logs are not installed according to the log
installationinstructions,flameimpingementand
impropercombustioncouldoccurandresultinsoot
and/or excessive production of carbon monoxide
(CO), a colorless, odorless, toxic gas.
Step 1. Install the ceramic panels, if necessary, per the instructions
provided in kit (reference form #750182M).
Step 2. Place a mixture of volcanic stone and vermiculite around the
Glowing Embers (Rockwool)
burner as shown in Figure 7.
Figure 6
Step 3. Separatetheglowingembers(rockwool)intopiecesaboutthesize
of a quarter (see Figure 5). Keep the pieces fluffed, not matted.
Distribute these pieces over the burner as shown in Figure 6.
Do not use more than necessary. When properly positioned,
the Glowing Embers will cover approximately 75% of the burner
on natural gas. For propane gas, do not place embers on main
ports.
Note: Excessive use of embers may result in sooting or poor flame.
This appliance is provided with enough Glowing Embers for several
applications, do not feel compelled to use all that is in a new bag. For
best glowing effect, replace the ember material annually. Replacement
Glowing Embers are available (Catalog Number 88L53).
Step 4. Position the individual logs as shown in Figures 8 through 12.
Logs should be placed in the order shown. Place logs 2 and 3
against the pins on the grate, NOT over them.
Mixture Of Volcanic Stone And Vermiculite
Figure 7 - (LSM45-2 Shown)
Proper log and twig placement is critical to encourage outstand-
ing flame appearance and prevent sooting. When positioned
properly as shown, twigs will be positioned between flame
peaks and will not impinge any flames. Positioning is the same
for all colors of log sets.

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. After 15 minutes of
operation, if the flame is blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.
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 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 combus-
tion in the flames and lack of combustion air
entering the air shutter opening. To achieve a
warm yellowish-orange flame with an orange
Figure 13 - Burner Flame Appearance
body that does not soot, the shutter opening
must be adjusted between these two extremes.
Air Shutter Adjustment Guidelines
(Rustic Oak Logs Shown) LSM45-2
• 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
openedtoofar, mayhaveflamesthatappear
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.
