High Altitude Installations

U.L. Listed gas appliances 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 appliance 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 appliance 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 appliance 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.

in separate packages. The gas logs are packaged
separately and must be field installed.

Read all of the instructions before starting the
installation. Follow these instructions carefully during
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 manu-

factured and approved by Heat-N-Glo, not withstanding

any independent testing laboratory or other party approval

4. The solid fuel fireplaces flue damper must be fully locked
in the open position or removed for installation.

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.

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.

8. Install decorative trim surround. Please refer to instruc­tions included with the trim surround.

Ensure there are no obstructions to side air

!

passages by the decorative trim once it is in­stalled on insert.

When planning a fireplace insert installation, its necessary
to determine:

 The vent system configuration to be used.
 Gas supply piping.
 Whether optional accessoriesdevices such as a wall

switch or remote controlare desired.

Installing the Insert

Step 1. Installing the Vent System

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.

Consult your local building codes before beginning the
installation.

WARNING: THIS GAS INSERT AND VENT AS-

!

SEMBLY 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.

Vent System Approvals

Models: Vent System
CFX-IN LINK-DV30, LINK- DV4-30
CFX-GRAND LINK-DV30, LINK-DV4-30

Table 1

Table 1 and Figures 4 through 6 show the vent termination
caps and systems approved for the use with these models.
Approved vent system terminations are labeled for identifi­cation. 3-inch diameter 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 COMPONENTS MAY BE USED. Detailed in­stallation instructions are included with each vent termina­tion kit and should be used in conjunction with this manual.

Horizontal Venting

The vent system on this model CANNOT be terminated
horizontally.

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 com­bustion air vent pipe CAN be connected to the termination
cap (LINK -DV30) or it can terminate inside the chimney
(LINK-DV4-30). 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 4, 5
and 6.

NOTE: The minimum vertical rise (exhaust vent) is 14 feet
and the maximum vertical rise is 40 feet. These dimensions
are measured from the starting collars of the unit to the end
of the last section of vent pipe. See dimension V in Figure 4.

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.

NOTE: The damper of the masonry chimney may need to
be removed to allow installation of the flexible-vent pipe.

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.

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.

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
ends of flexible pipe. Slide the gas insert into place, and
position any excess flexible vent pipe back up into the
chimney.

WARNING: THE 3 SECTION OF STAINLESS

!

STEEL FLEXIBLE PIPE MUST BE ATTACHED

DIRECTLY TO THE EXHAUST COLLAR OF THE UNIT.

Using the provided T-handle pull down tool, reach through
exhaust opening in exhaust collar by its center pin. Pull
down until exhaust collar extends through exhaust opening.
The collar should slip fit through the molded in 3 inch opening.
Carefully readjust liners to align if necessary.

Secure in place by sliding retainer pin through the provided
holes in the exhaust collar. See Figure 5.

Attach either 4 or 30 section of intake liner to the intake
collar assembly on top of the fireplace using 3 screws. This
assembly may be removed from the unit to aid installation.
Slide insert into position, while pulling intake collar assembly
towards the front of the unit. This assembly will be secured
in place when the pull handle can be locked into position at
locking tabs.

WARNING: DO NOT FORCE

!

COLLAR ATTACHMENT INTO
PLACE. THE FIREPLACE IS MADE
OF A FRAGILE MATERIAL, AND
MAY BREAK. READJUST FLEXI­BLE VENT PIPES IF NECESSARY.

Attach the pipe-to-cap adaptor to the
termination cap and to the top of the
flexible vent pipe and set the cap in place
at the top of the chimney. See Figures 4,
5 and 6.

CAUTION: TO AVOID DOWNDRAFTS
AND/OR COLD AIR PROBLEMS, IT IS
RECOMMENDED TO SEAL OFF THE
AREA BETWEEN THE TERMINATION
CAP AND THE TOP OF THE SOLID­FUEL CHIMNEY OPENING INTO
WHICH THE VENT CAP HAS BEEN IN­STALLED.

WHEN USING THE LINK-DV4-3O VENT
SYSTEM, IT IS REQUIRED TO SEAL
AROUND THE FLEXIBLE VENT PIPES
IN THE DAMPER AREA. SEE FIGURE

Step 3. The Gas Control System

WARNING: THIS UNIT IS NOT FOR USE WITH

!

SOLID FUEL.

These models use a standing pilot ignition type of gas con­trol system.

Standing Pilot Ignition System

This system includes millivolt control valve, standing pilot,
thermopile/thermocouple flame sensor, and piezo ignitor.

WARNING: 110-120 VAC MUST NEVER BE

!

CONNECTED TO A CONTROL VALVE IN A
MILLIVOLT SYSTEM.

STANDING PILOT

NOTE: Consult local building codes to properly size
the gas supply line leading to the 1/2 inch (13 mm)
hook-up at the unit.

This gas fireplace is designed to accept a 1/2 inch
(13 mm) gas supply line. To install the gas supply line:

 A listed (and State of Massachusetts approved) 1/2 inch

(13mm) tee-handle manual shut-off valve and a listed
flexible gas connector are connected to the 1/2 inch
(13mm) inlet of the control valve. NOTE: If substituting
for these components, please consult local codes for
compliance.

 Locate the gas line access hole in the outer casing of

the fireplace.

 Open the lower grille, insert the gas supply line through

the gas line hole, and connect it to the shut-off valve.

Step 7. Installing Logs and Ember Material

Positioning the Logs

The logs for models CFX-IN and CFX-Grand have been
packaged separately. Refer to the installation instructions
that accompany this manual. Save the log instructions

with this manual.

If sooting occurs, the logs might need to be repositioned
slightly to avoid excessive flame impingement.

Placing the Ember Material

Three separate bags of ember material are shipped with
this gas appliance. The bag labeled Golden Ember (GE-

93) is flame colorant material. The bags labeled Glowing
Ember (050-721) is standard glowing ember material.

To place the ember material:
 Remove the glass door from the unit (see Figure 10).

 Place a dime size piece of glowing ember material near

port holes in burner top, sides and front (see Figure 11).

Before lighting the appliance, be sure to do the following:

Remove all paperwork from underneath the fireplace.

Review safety warnings and cautions

 Read the Safety and Warning Information section at

the beginning of this Installers Guide.

Double-check for gas 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 ter­minations.

Double-check for faulty components

 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 war­ranties.

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.

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.

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 check­up at the beginning of each heating season. See the table
below for specific guidelines regarding each fireplace main­tenance task.

IMPORTANT: TURN OFF THE GAS BEFORE SERVICING
YOUR FIREPLACE.

Replacing old ember material
Frequency: Once annually, during the checkup.
By: Qualified service technician.
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.

Cleaning Burner and Controls
Frequency: Once annually.
By: Qualified service technician.
Task: Brush or vacuum the control compartment, fireplace

logs and burner areas surrounding the logs.

MAKE SURE THE FLAMES
ARE STEADYNOT
LIFTING OR FLOATING.

Figure 14. Burner Flame Patterns

Checking Vent System
Frequency: Before initial use and at least annually

thereafter, more frequently if possible.

By: Qualified service technician/Home owner.
Task: Inspect the external vent cap on a regular basis to

ensure that no debris is interfering with the flow of air. Inspect
entire vent system for proper function.

Checking Flame Patterns, Flame Height
Frequency: Periodically.

By: Qualified service technician/Home owner.
Task: Make a visual check of your fireplaces flame patterns.

Make sure the flames are steady - not lifting or floating.
