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 fit firmly 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 floor of the fireplace or firebox.
Proper Primary Airflow into Burner
For proper burner operation and flame appearance, the flow
of primary air into the venturi tube, located on the rear of
the burner, must not be reduced. This flow 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 flow of air into the venturi is also reduced
if the gas orifice isn't centered in the venturi inlet and/or is
not aligned with the venturi. Any misalignment of the burner
orifice may be corrected by bending the shutter cap holding
the orifice to the inlet of the venturi tube.
ceiling fans, Portable fans or Logs Installed Near cold
Air returns
Ceiling fans or oscillating floor type fans need to be monitored
during the operation of vent-free logs. If the air blows directly
into the flame causing it to impinge on the log set, or firebox,
it should be turned off or redirected. Ceiling fans could be
reversed to possibly eliminate flame impingement, and the
floor 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
flame to impinge on the log and create a sooting situation.
wArNINg: Do not allow fans to blow directly into the fireplace.
Avoid any drafts that alter burner flame 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 magnifies 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 fireplace, you must raise
the floor to insure adequate airflow and guard against sooting.
Raise fireplace floor using a non-combustible 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
dimension used for the minimum front opening of the firebox.
woodburning fireplaces
The interior of the firebox 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
log set causing odors and possibly sooting.
wArNINg: Before installing in a solid-fuel burning fireplace,
the chimney flue and firebox must be cleaned of soot, creosote,
ashes and loose paint by a qualified chimney cleaner.
