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. It
must be positioned only on the front portion of the burner. The photos
in this manual show the proper placement of rock wool.
Decorative lava rock or small wood pieces should never be placed
on the burner. These items are only for placement on the oor of
the replace or rebox.
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. This ow of air is reduced if dirt, lint or other
obstructions build-up around or inside the venturi. Any obstruction
in the venturi tube area must be removed. The ow of air into the
venturi is also reduced if the gas orice isn’t centered in the venturi
inlet and/or is not aligned with the venturi. Any misalignment of the
burner orice may be corrected 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 oor type fans need to be monitored
during the operation of vent-free logs. If the air blows directly into
the ame causing it to impinge on the log set, or rebox, it should be
turned off or redirected. Ceiling fans could be reversed to possibly
eliminate ame impingement, and the oor fan could be redirected.
Upon installation, be aware of any cold air returns or vents in the
proximity of the log set. Any draft created around a vent-free log
set can cause the ame to impinge on the log and create a sooting
situation.
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 log set is operating magnies
the problem. It should be noted that candles, in general, produce
soot. The amount of time burned and the quantity of candles burned
will determine the amount of soot produced and deposited.
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 appear on a log, call for service.
Do not continue to operate the log set.
Sunken Fireplace
If installing this unit into a sunken replace, you must raise the oor
to insure adequate airow and guard against sooting. Raise replace
oor using a non-combustible material, which is secure.
Glass Doors
Make sure that glass doors are 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 should be cleaned and
free of all creosote before installing a gas burning log set. Creosote
will soften when heated and can drop on the logset causing odors
and possibly sooting.
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.
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.
State of Massachusetts: The installation must be made by a
licensed plumber or gas tter in the Commonwealth of Massa-
chusetts.
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 State of Massachusetts, unvented propane and natural
gas-red space heaters shall be prohibited in bedrooms and
bathrooms.
IMPORTANT INSTALLATION GUIDELINES
GENERAL INFORMATION

28189-2-0315Page 4
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 or to controls
can be dangerous. 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 pan location and log place-
ment is important to achieve optimum look and perfor-
mance 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 this log set with glass doors in the closed
position. A replace screen must be in place when the
log set is burning. Adequate combustion air must be
provided for proper venting. All ames should go up and
out the top of the rebox into the ue vent. If any ames
oat or curl forward into the room do not operate appli-
ance. Check for an open ue and adequate combustion
air into the room. A damper clamp must be installed on
the rebox damper to maintain an open ue vent condi-
tion. Refer to replace owners manual INSTALLING
DAMPER CLAMP section.
4. Young children must be carefully supervised when they
are in the same room as the gas log while in operation.
Do not place stockings, clothing or any ammable ma-
terial above or near the replace.
5. Do not substitute or use materials other than those sup-
plied for use with the log set.
6. Also refer to IMPORTANT SAFETY INFORMATION in
the replace Owner's Manual.
