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.
