INFORMATION
BULLETIN
NUMBER: 02-1
MODELS: Vent-Free Log Sets
PURPOSE: This is a general information bulletin written to insure the proper installation, application, and use of vent-free log sets.
There are many factors that come into play when there is an occurrence of sooting with any log set. We have compiled the following
informtion to cover any potential issue that can create sooting. Preventative measures taken before initial start up can avoid future
issues with log sets.
IMPORTANT INSTALLATION GUIDELINES
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. Misformed logs or logs with sloppy 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.
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 minumum front opening of the rebox.
Woodburning Fireplaces
The interior of the rebox and the chimney should be cleared and
free of all creosote before installing a gas burning log set. Creosote
will soften when heated and can drop on the log set casuing odors
and possible sooting.
