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 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 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 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 logset 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.

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 precau- tions required, and that has complied with all the requirements of the authority having jurisdiction.

The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/ NFPA54.*

*Available from the American National Standards Institute, Inc. 11 West 42nd St., New York, N.Y. 10018.

State of Massachusetts: The installation must be made by a licensed plumber or gas ﬁtter in the Commonwealth of Mas- sachusetts.

Sellers of unvented propane or natural gas-ﬁred supplemental room heaters shall provide to each purchaser a copy of 527 CMR 30 upon sale of the unit.

In the State of Massachusetts, unvented propane and natural gas-ﬁred space heaters shall be prohibited in bedrooms and bathrooms.
