Proper Log Placement
Log placement is critical to proper burner performance. Logs must
be correctly positioned onto the burner. The photos in this manual
show the proper pinned position for logs on this set. Owners need to
be shown proper log placement and instructed not to move the logs.
Logs must t rmly onto the burner when positioned as shown in the
photos. Malformed logs or logs with sloppy pin holes must be replaced.
Proper Placement of Rock Wool and Decorative Lava Rock
Rock wool can be added to burners for a glowing ember effect. Place
on the front portion of the burner only. The photos in this manual
show the proper placement of rock wool.
Never place decorative lava rock or small wood pieces on the burner.
Place them on the oor of the replace or rebox only.
Proper Primary Airow into Burner
For proper burner operation and ame appearance, the ow of
primary air into the venturi tube, located on the rear of the burner,
must not be reduced. Air ow may be reduced if dirt, lint or other
obstructions build-up around or inside the venturi. Any obstruction
must be removed. Air ow into the venturi is also reduced if the gas
orice isn’t centered in the venturi inlet or is not aligned with the
venturi. Correct any misalignment of the burner orice by bending
the shutter cap holding the orice to the inlet of the venturi tube.
Ceiling Fans, Portable Fans or Logs Installed Near Cold Air Returns
Ceiling fans or oscillating fans need to be monitored during the
operation of this vent-free burner. If air blows directly into the ame
causing it to impinge on the log set, or rebox, turn off or redirect the
fan. Ceiling fans may be reversed to eliminate ame impingement.
Upon installation, be aware of any cold-air returns or vents in the
proximity of the burner. Any draft created around a vent-free burner
can cause ame impingement and create soot.
WARNING
Do not allow fans to blow directly into the replace. Avoid
any drafts that alter burner ame patterns.
WARNING
Do not use a blower insert, heat exchanger insert or other
accessory not approved for use with this heater.
Candles
Avoid the use of scented or decorative candles while the log set is
in operation. Candles produce a residue in the air that creates a
soot-like substance. Burning candles while the burner is operating
magnies the problem. Candles in general produce soot. The
amount of time burned and the quantity of candles will determine
the amount of soot produced.
Make Owners Aware of Proper Log Set Operation
Properly installed and properly maintained log sets do not deposit
soot on the logs. If users see soot on a log, they should call for
service. Do not continue to operate the log set.
Sunken Fireplace
If installing this unit into a sunken replace, raise the oor to ensure
adequate airow and guard against sooting. Raise replace oor
using a non-combustible material, which is secure.
Glass Doors
Keep glass doors open during all operations of the logset. The
opening of the glass door frame should be the dimension used for
the minimum front opening of the rebox.
Wood-Burning Fireplaces
The interior of the rebox and the chimney must be cleaned and free
of all creosote before installing a gas log set. Creosote will soften
when heated and can drop onto the logset causing odors and soot.
WARNING
Before installing in a solid-fuel burning replace, the chimney
ue and rebox must be cleaned of soot, creosote, ashes
and loose paint by a qualied chimney cleaner.
Initial Operation
Once the installation is complete and the logs and embers are
in place, light the burner and operate it on high for a minimum of
three continuous hours. This will burn off any foreign materials,
such as dust or paint overspray, that might cause odors during
normal operation. Open windows or doors as needed to allow
odors and excess heat to escape.
Qualied Installing Agency
Installation and replacement of gas piping, gas utilization equip-
ment or accessories and repair and servicing of equipment shall be
performed only by a qualied agency. The term "qualied agency"
means any individual, rm, corporation, or company that either in
person or through a representative is engaged in and is responsible
for (a) the installation, testing, or replacement of gas piping or (b) the
connection, installation, testing, repair, or servicing of equipment;
that is experienced in such work; that is familiar with all precautions
required, and that has complied with all the requirements of the
authority having jurisdiction.
The installation must conform with local codes or, in the absence of
local codes, with the National Fuel Gas Code,ANSI Z223.1/NFPA54.*
*Available from the American National Standards Institute, Inc. 11 West
42nd St., New York, N.Y. 10018.
Commonwealth of Massachusetts: The installation must be
made by a licensed plumber or gas tter in the Commonwealth of
Massachusetts. Sellers of unvented propane or natural gas-red
supplemental room heaters shall provide to each purchaser a
copy of 527 CMR 30 upon sale of the unit. In the Commonwealth
of Massachusetts, unvented propane and natural gas-red space
heaters shall be prohibited in bedrooms and bathrooms.

REQUIREMENTS FOR CANADA
This unit cannot be installed in a UNVENTED application,
this unit can only be installed as a VENTED application
with these requirements.
IMPORTANT SAFETY INFORMATION
This unit complies with ANSI Z21.60and CGA 2.26 Decora-
tive Gas Appliances For Installation In Solid Fuel Burning
Fireplaces. Do not burn wood or solid fuels in a replace
where a decorative gas log set is installed. This appliance is
for installation only in a solid fuel burning replace, masonry
replace or manufactured replace.
WARNING: Any modication to this gas log set can be dan-
gerous. Improper installation or use of the gas log set can
cause serious injury or death from re, burns, explosion or
carbon monoxide poisoning.
1. Please follow all local codes regarding installation,
combustion and ventilation air or in the absence of
local codes follow the National Fuel Gas Code ANSI
Z223.1(U.S. installation), or CAN/CGA-B149, Installa-
tion Code (Canada installation).
2. Proper installation, burner location and log placement
is important to achieve optimum look and performance
of your gas log set. The logs have been designed for
easy location and placement on the grate and must be
followed for proper operation.
3. Do not operate the burner with glass doors in the closed
position. A replace screen must be in place when the
burner is burning. Adequate combustion air must be
