Appliance Certification
u
High Altitude Installations
The Heat-N-Glo appliance models discussed in this
Installers Guide have been tested to certification standards
and listed by the applicable laboratories.
U.L. Listed gas appliances are tested and approved with-
out requiring changes for elevations from 0 to 2,000 feet in
the U. S. A. and in Canada.
Certification
When installing this appliance at an elevation above 2,000
feet, it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Input
rate should be reduced by 4% for each 1000 feet above a
2000 foot elevation in the U.S.A. or 10% for elevations
between 2000 and 4500 feet in Canada. If the heating value
of the gas has been reduced, these rules do not apply. To
identify the proper orifice size, check with the local gas
utility.

Getting Started
Introducing the Heat-N-Glo Gas Appliances
3. To assure top performance, safety and efficiency, inserts
must be installed with an approved flue liner as per CAN/
CGA B-149 or National Fuel CodeANSI Z223 and these
instructions.
Heat-N-Glo direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.
WARNING: A HEARTH OR HEARTH EXTEN-
SION (IF PRESENT) MUST COMPLY WITH EI-
THER OF THE FOLLOWING: 1) THE SOLID-FUEL
BURNING FIREPLACE MANUFACTURER’S SPECI-
FICATION, OR 2) LOCAL BUILDING CODES RE-
QUIRED BY AUTHORITY HAVING JURISDICTION.
The information contained in this Installers Guide, unless
noted otherwise, applies to all models and gas control
systems. Gas appliance diagrams, including the dimensions,
are shown in this section.
!
Pre-install Preparation
This gas insert 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 damaged, incomplete, or substitute parts.
WARNING: THE SOLID FUEL FIREPLACE HAS
BEEN CONVERTED FOR USE WITH GAS
!
ONLY AND CANNOT BE USED FOR BURNING
WOOD OR SOLID FUELS UNLESS ALL ORIGINAL
PARTS HAVE BEEN REPLACED AND THE FIRE-
PLACE HAS BEEN REAPPROVED BY THE AUTHOR-
ITY HAVING JURISDICTION.
The vent system components and trim surrounds are shipped
in separate packages. The gas logs are packaged
separately and must be field installed.
4. The solid fuel fireplace’s flue damper must be fully locked
in the open position or removed for installation.
Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefit.
Failure to follow these instructions will void the own-
er’s warranty and may present a fire hazard.
5. The chimney must be cleaned and in good working order
and constructed of noncombustible materials.
6. Make sure that all chimney cleanouts fit properly so air
cannot leak into the chimney.
The Heat-N-Glo Warranty will be voided by, and Heat-N-Glo
disclaims any responsibility for, the following actions:
• Installation of 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 manu-
factured and approved by Heat-N-Glo, not withstanding
any independent testing laboratory or other party approval
of such component part or accessory.
7. Install the insert without the trim surround and make all
gas, venting, and electrical connections.
WARNING: Modification of any sheetmetal or
fiber surfaces is strictly PROHIBITED in the
!
installation of this appliance.
Only trim kit(s) supplied by the manufacturer shall
be used in the installation of this appliance.
ANY SUCH ACTION MAY POSSIBLY CAUSE A FIRE
HAZARD.
8. Install decorative trim surround. The surround is tested
AND approved with this gas insertAND may cover exist-
ing air circulation vents or grills on the solid fuel fireplace
into which it is installed. Should the surround not cover
all ventilation grill surfaces, the grill should be left open.
NOTE: DECORATIVE TRIM SURROUND HAS BEEN
TESTED AND APPROVED TO COVER EXISTING AIR
CIRCULATION VENTS OR GRILLS.
VENTING AND INSTALLATION
1. Heat-N-Glo gas inserts are designed for recessed instal-
lations into solid fuel masonry or factory built non-com-
bustible fireplaces that have been installed in accordance
with the National, Provincial, State and local building codes.
2. Minimum fireplace opening requirements are shown in
Figures 1 and 2 of this installation manual. The firebrick
(refractory) can be removed from a factory built fireplace
in order to gain minimum gas insert opening requirements.
WARNING: Only the surround, as supplied,
may be used to cover integral grills on the
!
solid fuel burning fireplace. No other components
such as shrouds, sheet metal plates, etc. may be
used to seal off vents. Remote grills or openings
outside of the surround MUST NOT be covered or
sealed.
WARNING: Under no circumstances is cutting
of sheet metal surfaces allowed for installation.
!
If the factory built fireplace has no gas ac-

Installing the Insert
of the last section of vent pipe. See dimension V in Figure 4.
Step 1. Installing the Vent System
A vertical vent termination system installed on this model
will include one (1) length of 3-inch flexible vent pipe for the
combustion air, one (1) length of 3-inch flexible vent pipe for
the exhaust air, one (1) pipe-to-cap adaptor, and one (1)
SLK-991DA or SLK-980D Vertical Termination Cap.
Vent System Installation Precautions
Before starting installation of vent kits, the installer should
read these instructions and the Vent Kit Instructions to
ensure that a proper vent installation is completed.
NOTE: The damper of the masonry chimney may need to
be removed to allow installation of the flexible-vent pipe.
Consult your local building codes before beginning the
installation.
This fireplace has been altered to accommodate an
insert and should be inspected by a qualified person
prior to re-use as a conventional fireplace.

MUST USEASEPARATE VENT SYSTEM. COMMON
VENT SYSTEMS ARE PROHIBITED.
NOTE: The above label, located in the instruction package,
must be affixed to the existing fireplace prior to installation.
For zero clearance factory built woodburning fireplaces, the
use of kit LINK-ZC-ADP in place of the standard square
flashing will allow you to mount the adaptor and cap on
metal pipe. Additionally, the use of kit FLASH-DAMP will
seal off the damper opening when terminating the inlet air
vent pipe just above the damper. These 2 kits are
recommended for zero clearance, factory built woodburning
fireplaces.
Vent System Approvals
Models CFX-Grand-B, CFX-IN-B, FB-IN and FB-GRAND is
approved with vent termination kits LINK-DV-30, LINK-DV-
30B, LINK-DV4-30 and LINK-DV4-30B.Approved vent sys-
tem terminations are labeled for identification. 3-inch diam-
eter listed flexible aluminum and stainless steel gas vent is
used for both the incoming combustion air and exhaust
vent pipes. NO OTHER VENTING SYSTEMS OR COM-
PONENTS MAY BE USED. Detailed installation instruc-
tions are included with each vent termination kit and should
be used in conjunction with this manual.
Connecting the Vent Pipe
Install the 3” flexible vent pipe(s) down through the chimney.
Secure the end of the flexible vent pipe for exhaust to the
provided 3’ section of stainless steel flexible vent pipe. A 3”
collar is factory installed on one end for mating the two

Vertical Venting
The vent pipes MUST be connected to the proper collars
on the unit AND the exhaust vent pipe MUST be connected
to the termination cap or the unit will not operate. The com-
bustion air vent pipe CAN be connected to the termination
cap (LINK -DV30, LINK -DV30B) or it can terminate inside
the chimney (LINK-DV4-30, LINK-DV4-30B). The bottom
opening of the chimney must be sealed around the vent
pipes if the combustion air vent is NOT connected to the
termination cap. See Figures 3 and 4.

Review safety warnings and cautions
• Read the Safety and Warning Information section at
the beginning of this Installers Guide.
Double-check for gas leaks
NOTE: PLACE THE THREE INSULATION PIECES INTO
THE CAVITIES AT THE BACK OF THE SURROUND BE-
FORE POSITIONING THE INSERT INTO THE FACTORY-
BUILT OR MASONRY FIREPLACE. THIS INSULATION
WILL HELP SEAL FOR COLD AIR LEAKS.
• Before lighting the appliance, double-check the unit for
possible gas leaks.
Double-check vent terminations for obstructions.
• Before lighting the appliance, double-check the unit for
possible obstructions that could be blocking the vent ter-
minations.
Double-check for faulty components
12” MAX.
• Any component that is found to be faulty MUST BE re-
placed with an approved component. Tampering with the
appliance components is DANGEROUS and voids all war-
ranties.
MANTEL
A small amount of air will be in the gas supply lines. When
first lighting the appliance, it will take a few minutes for the
lines to purge themselves of this air. Once the purging is
complete, the appliance will light and will operate normally.
12” MIN.
Subsequent lightings of the fireplace will not require this
purging of air from the gas supply lines, unless the gas
valve has been turned to the OFF position, in which
case the air would have to be purged.
TOP OF
UNIT
NOTE: The fireplace should be run 3 to 4 hours on the initial
start-up. Turn it off and let it cool completely. Remove and
clean the glass. Replace the glass and run the fireplace for
an additional 8 hours. This will help to cure the chemicals
used in the paint and logs.
Step 10. Lighting the Appliance
You’ve reviewed all safety warnings, you’ve checked the
appliance for gas leaks, you know the vent system is
unobstructed, and you’ve checked for faulty components.
Now you’re ready to light the appliance.

Maintaining and Servicing Your Appliance
Appliance Maintenance
Although the frequency of servicing and maintenance will
depend on use and the type of installation, you should have
a qualified service technician perform an appliance check-
up at the beginning of each heating season. See the table
below for specific guidelines regarding each fireplace main-
tenance task.
IMPORTANT: TURN OFF THE GAS BEFORE SERVICING
YOUR FIREPLACE.
Replacing old ember material
Frequency: Once annually, during the checkup.
By: Qualified service technician.
MAKE SURE THE FLAMES
ARE STEADY—NOT
LIFTING OR FLOATING.
Task: Brush away loose ember material near the burner.
Replace old ember material with new dime-size and shape
pieces of Golden Ember (DE-93) and Glowing Ember (050-
721). New ember material should be placed alternately on
top of the burner - a layer of Golden Ember, a layer of
Glowing Ember, and so on. Save the remaining ember
material and repeat this procedure at your next servicing.
For more information, see Placing Ember Material.
