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. 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 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.

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

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 log
set. The opening of the glass door frame should be the dimension

used for the minimum front opening of the rebox.

Woodburning Fireplaces

The interior of the rebox 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 replace, the chimney
ue and rebox must be cleaned of soot, creosote, ashes
and loose paint by a qualied chimney cleaner.

WARNING

Do not allow fans to blow directly into the replace. Avoid
any drafts that alter burner ame patterns.

REQUIREMENTS FOR CANADA

This unit cannot be installed in a UNVENTED application, this
unit can only be installed as a VENTED application with these
requirements.

IMPORTANT SAFETY INFORMATION

This unit complies with ANSI Z21.60and CGA 2.26 Decorative
Gas Appliances For Installation In Solid Fuel Burning Fireplaces.

Do not burn wood or solid fuels in a replace where a decorative

gas log set is installed. This appliance is for installation only in

a solid fuel burning replace, masonry replace or manufactured
replace.

WARNING

Any modication to this gas log set or to controls can be

dangerous. Improper installation or use of the gas log set
can cause serious injury or death from re, burns, explo­sion or carbon monoxide poisoning.

1. Please follow all local codes regarding installation, combus­tion and ventilation air or in the absence of local codes follow
the National Fuel Gas Code ANSI Z223.1(U.S. installation), or
CAN/CGA-B149, Installation Code (Canada installation).

2. Proper installation, burner pan location and log placement is
important to achieve optimum look and performance of your
gas log set. The logs have been designed for easy location
and placement on the grate and must be followed for proper
operation.

3. Do not operate this log set with glass doors in the closed po-

sition. A replace screen must be in place when the log set

is burning. Adequate combustion air must be provided for

proper venting. All ames should go up and out the top of the
rebox into the ue vent. If any ames oat or curl forward

into the room do not operate appliance. Check for an open

ue and adequate combustion air into the room. A damper
clamp must be installed on the rebox damper to maintain an
open ue vent condition. Refer to replace owners manual

INSTALLING DAMPER CLAMP section.

4. Young children must be carefully supervised when they are in
the same room as the gas log while in operation. Do not place

stockings, clothing or any ammable material above or near
the replace.

5. Do not substitute or use materials other than those supplied
for use with the log set.

6. Also refer to IMPORTANT SAFETY INFORMATION in the

replace Owner's Manual.

WARNING

DO NOT OPERATE THIS GAS LOG SET WITH GLASS
DOORS CLOSED

• Clothing or other ammable material should not be placed on

or near the appliance.

• Do not place trash or other articles on the log set during op­eration.

• During manufacturing, fabricating and shipping, various com-

ponents of this appliance are treated with certain oils, lms or

bonding agents. These bonding agents are not harmful but
may produce annoying smoke and smells as they are burned
off during initial operation of the appliance. This is a normal
temporary occurrence. A window should be opened during the
initial bake out period.

• Keep burner and control compartment clean.

WARNING

Before installing in a solid fuel burning replace, the chim­ney ue and rebox must be cleaned of soot, creosote,
ashes and loose paint by a qualied chimner cleaner

• Installation and repair should be done by a qualied service

person. The appliance should be inspected before use and

at least annually by a qualied service person. More frequent
cleaning may be required due to excessive lint from carpeting,

bedding materials, etc. It is imperative that control compart­ments, burners and circulating air passageways of the appli­ance be kept clean.

• Do not put anything around the replace that will obstruct the

ow of ventilation air.

• Do keep the appliance area clear and free from combustible

material, gasoline and other ammable vapors and liquids.

• A yearly examination and cleaning of the venting system of
the solid-fuel burning replace must be performed by a quali­ed agency.

• Do make a periodic visual check of pilot and burners. Clean
and replace damaged parts.

• Do not use this appliance if any part has been under water.

Immediately call a qualied service technician to inspect the

appliance and to replace any part of the control system and
any gas control which has been under water.

• Never burn solid fuels in replace where a gas log set is in­stalled.

• This unit complies with ANSI Z21.60 Decorative Vented Appli­ances for Solid Fuel Burning Fireplaces. State or local codes
may only allow operation of this appliance in a vented congu­ration. Check your state or local codes.
