SAFETY AND WARNING INFORMATION
READ and UNDERSTAND all instructions carefully before starting the installation.
FAILURE TO FOLLOW these installation instructions may result in a possible fire
hazard and will void the warranty.
Prior to the first firing of the fireplace, READ the Using Your Fireplace section of the
Owners Guide.
DO NOT USE this appliance if any part has been under water. Immediately CALL a
ualified service technician to inspect the unit and to replace any part of the control
system and any gas control which has been underwater.
THIS UNIT IS NOT FOR USE WITH SOLID FUEL.
Installation and repair should be PERFORMED by a ualified service person. The
appliance and venting system should be INSPECTED before initial use and at least
annually by a professional service person. More fre uent cleaning may be re uired due
to excessive lint from carpeting, bedding material, etc. It is IMPERATIVE that the units
control compartment, burners, and circulating air passageways BE KEPT CLEAN to
provide for ade uate combustion and ventilation air.
Always KEEP the appliance clear and free from combustible materials, gasoline, and
other flammable vapors and li uids.
NEVER OBSTRUCT the flow of combustion and ventilation air. Keep the front of the
appliance CLEAR of all obstacles and materials for sevicing and proper operations.
Due to the high temperature, the appliance should be LOCATED out of traffic areas and
away from furniture and draperies. Clothing or flammable material SHOULD NOT BE
PLACED on or near the appliance.
Children and adults should be ALERTED to the hazards of high surface temperature and
should STAY AWAY to avoid burns or clothing ignition. Young children should be
CAREFULLY SUPERVISED when they are in the same room as the appliance.
These units MUST use one of the vent systems described in the Installing the Fireplace
section of the Installers Guide. NO OTHER vent systems or components MAY BE USED.
This gas fireplace and vent assembly MUST be vented directly to the outside and MUST
NEVER be attached to a chimney serving a separate solid fuel burning appliance. Each
gas appliance MUST USE a separate vent system. Common vent systems are
PROHIBITED.
INSPECT the external vent cap on a regular basis to make sure that no debris is
interfering with the air flow.
The glass door assembly MUST be in place and sealed, and the trim door assembly
MUST be in place on the fireplace before the unit can be placed into safe operation.
DO NOT OPERATE this appliance with the glass door removed, cracked, or broken.
Replacement of the glass door should be performed by a licensed or ualified service
person. DO NOT strike or slam the glass door.
The glass door assembly SHALL ONLY be replaced as a complete unit, as supplied by
the gas fireplace manufacturer. NO SUBSTITUTE material may be used.

Installation Codes
The fireplace installation must conform to local codes. Before installing the
fireplace, consult the local building code agency to ensure that you are in
compliance with all applicable codes, including permits and inspections.
In the absence of local codes, the fireplace installation must conform to the
National Fuel Gas Code ANSI Z22 .1 (in the United States) or the CAN/CGA-
B149 Installation Codes (in Canada). The appliance must be electrically
grounded in accordance with local codes or, in the absence of local codes with
the National Electric Code ANSI/NFPA No. 70 (in the United States), or to the
CSA C22.1 Canadian Electric Code (in Canada).
These models may be installed in a bedroom or bed-sitting room in the U.S.A.
and Canada.

High Altitude Installations
U.L. Listed gas fireplaces are tested and approved for elevations from 0 to
2,000 feet in the U. S. A. and from 0 to 4,500 feet in Canada.
When installing this fireplace at an elevation above 2,000 feet (in the United
States), it may be necessary to decrease the input rating by changing the
existing burner orifice to a smaller size. Input should be reduced four percent
(4%) for each 1,000 feet above sea level, unless the heating value of the gas
has been reduced, in which case this general rule will not apply. To identify the
proper orifice size, check with the local gas utility.
When installing this fireplace at an elevation between 2,000 and 4,500 feet (in
Canada), the input rating must be reduced by ten percent (10%).
When installing this fireplace at an elevation above 4,500 feet (in Canada),
check with local authorities.
Consult your local gas utility for assistance in determining the proper orifice for
your location.

Getting
Started
Introducing the
Heat-N-Glo
Gas Fireplaces
Heat-N-Glo direct vent gas fireplaces are designed to
operate with all combustion air siphoned from outside
of the building and all exhaust gases expelled to the
outside.
The information contained in this Installers Guide,
unless noted otherwise, applies to all models and gas
control systems.
Gas fireplace diagrams, including the dimensions, are
shown in this section.
Pre-installation
Preparation
This gas fireplace and its components are tested and
safe when installed in accordance with this Installers
Guide. Report to your dealer any parts damaged in
shipment, particularly the condition of the glass. Do
not install any unit with dama ed, incomplete, or
substitute parts.
The vent system components and trim doors are
shipped in separate packages. The gas logs are
packaged separately and must be field installed.
Read all of the instructions before startin the
installation. Follow these instructions carefully
durin the installation to ensure maximum safety
and benefit. Failure to follow these instructions
will void the owners warranty and may present a
fire hazard.
The Heat-N-Glo Warranty will be voided by, and Heat-
N-Glo disclaims any responsibility for, the following
actions:
 Installation of any damaged fireplace or vent system
component.
 Modification of the fireplace or direct vent system.
 Installation other than as instructed by Heat-N-Glo.
 Improper positioning of the gas logs or the glass
door.
 Installation and/or use of any component part not
manufactured and approved by Heat-N-Glo, not
withstanding any independent testing laboratory or
other party approval of such component part or
accessory.
ANY SUCH ACTION MAY POSSIBLY CAUSE A
FIRE HAZARD.

When planning a fireplace installation, its necessary to determine:
Where the unit is to be installed.
The vent system configuration to be used.
Gas supply piping.
Electrical wiring.
Framing and finishing details.
Whether optional accessoriesdevices such as a fan, wall switch, or remote
controlare desired.
If the fireplace is to be installed on carpeting or tile, or on any combustible
material other than wood flooring, the fireplace should be installed on a metal or
wood panel that extends the full width and depth of the fireplace.

Framing the
Fireplace
Fireplace framing can be built before or after the
fireplace is set in place. Framing should be positioned
to accommodate wall coverings and fireplace facing
material. The diagram below shows framing reference
dimensions.
CAUTION MEASURE FIREPLACE DIMENSIONS, AND
VERIFY FRAMING METHODS AND WALL
COVERING DETAILS, BEFORE FRAMING
CONSTRUCTION BEGINS.
Framing should be
constructed of 2 X 4 lumber or heavier.
The framing headers may rest
on the fireplace stand-offs.

Fi ure 6. Vent Components and Terminations
A. Vent System Approvals
These models have vent starting collars on both the top and
the back of the unit. Depending upon the installation,
decide which ONE set of starting collars will be used to
attached the vent system. The starting collar sealing cap
must remain on the starting collar NOT used.
These models use SL-D-series, direct vent components
when using the TOP vent collars and D-series direct vent
components when using the REAR vent collars.
The flame and ember appearance may vary based on
the type of fuel burned and the venting configuration used.
WARNING YOU MUST NOT MIX D-SERIES
AND SL D-SERIES COMPONENTS IN ANY
VENT SYSTEM CONFIGURATION.
Identifying Vent Components
Approved vent system components are labeled for
identification. NO OTHER VENTING SYSTEMS OR
COMPONENTS MAY BE USED. Detailed installation
instructions are included with each vent termination kit
and should be used in conjunction with this Installers
Guide. Figure 6 shows vent system components and
terminations.
The vent systems installed on this gas fireplace may
include one, two, or three 90° elbow assemblies. The
relationships of vertical rise to horizontal run in vent
configurations using 90° elbows MUST BE strictly
adhered to. The rise to run relationships are shown in the
venting drawings and tables on the next several pages.
NOTE: Two 45° elbows may be used in place of one
90° elbow. You MUST always maintain the MAXIMUM
and MINIMUM rise-to-run ratios in the vent system
when using 45° elbows.
