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. Place 

on the front portion of the burner only. The photos in this manual  

show the proper placement of rock wool.
Never place decorative lava rock or small wood pieces on the burner. 

Place them on the floor of the fireplace or firebox only.

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. Air flow may be reduced if dirt, lint or other 

obstructions build-up around or inside the venturi. Any obstruction 

must be removed. Air flow into the venturi is also reduced if the gas 

orifice isn’t centered in the venturi inlet or is not aligned with the 

venturi. Correct any misalignment of the burner orifice 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 fans need to be monitored during the 

operation of this vent-free burner. If air blows directly into the flame 

causing it to impinge on the log set, or firebox, turn off or redirect the 

fan. Ceiling fans may be reversed to eliminate flame impingement. 

Upon installation, be aware of any cold-air returns or vents in the 

proximity of the burner. Any draft created around a vent-free burner 

can cause flame impingement and create soot.

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 burner is operating 

magnifies  the  problem.  Candles  in  general  produce  soot.  The 

amount of time burned and the quantity of candles will determine 

the amount of soot produced.

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 on a log, they should call for 

service. Do not continue to operate the log set.

Sunken Fireplace

If installing this unit into a sunken fireplace, raise the floor to ensure 

adequate airflow and guard against sooting. Raise fireplace floor 

using a non-combustible material, which is secure.

Glass Doors

Keep  glass  doors  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 firebox.

Wood-Burning Fireplaces

The interior of the firebox and the chimney must be cleaned and free 

of all creosote before installing a gas log set. Creosote will soften 

when heated and can drop onto the logset causing odors and soot.

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.

Initial Operation

Once  the  installation  is  complete  and  the  logs  and  embers  are 

in place, light the burner and operate it on high for a minimum of 

three  continuous  hours. This  will  burn  off  any  foreign  materials, 

such  as  dust  or  paint  overspray,  that  might  cause  odors  during 

normal  operation.  Open  windows  or  doors  as  needed  to  allow 

odors and excess heat to escape.

Qualified 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 qualified agency. The term "qualified agency" 

means any individual, firm, 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.
