INSTALLATION GUIDELINES
Qualied Installation Agency
This set should only be installed by a qualied
installation agency.
Proper Log Placement
Log placement is critical to proper burner
performance. Logs must be correctly po-
sitioned onto the burner. The illustrations
in this manual show the proper 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 posi-
tioned as shown in the illustrations. Malformed
logs or broken logs must be replaced.
Proper Primary Airow into the
Burner
For proper burner operation and ame ap-
pearance, 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 re-
duced 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 cor-
rected by bending the shutter cap holding the
orice to the inlet or 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 o󰀨 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.
Candles
Avoid the use of scented or decorative can-
dles 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.
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 re-
place oor using a noncombustible material,
which is secure.
Glass Doors
Make sure that glass doors are open during
all operations of the log set. The opening of
the glass door frame should be the dimen-
sion 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 be-
fore installing a gas burning log set. Creosote
will soften when heated and can drop on the
log set causing odors and possibly sooting.

INSTALLING LOGS
WARNING: Failure to position the parts in accordance with these
diagrams or failure to use only parts specically approved with this
heater may result in property damage or personal injury.
CAUTION: After installation and periodically thereafter, check to
ensure that no yellow ame comes in contact with any log. With the
heater set to High, check to see if yellow ames contact any log. If
so, reposition logs according to the log installation instructions in
this manual. Yellow ames contacting logs will create soot.
It is very important to install the logs exactly as instructed. Do not modify logs. Use only logs
supplied with heater.
Each log is marked with a number. This number will help you to identify the logs when installing.
After installing logs, add decorative cinders around the grate base, do not place any decora-
tive cinders on logs or burner.
