Appliance Certification
The Heat-N-Glo fireplace models discussed in this Installers
Guide have been tested to certification standards and listed
by the applicable laboratories.
Certification
MODELS: 7000XLT, 6000XLTB
LABORATORY: Underwriters Laboratories
TYPE: Direct Vent Gas Fireplace Heaters
STANDARD: ANSI Z21.88CSA2.33
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 Z223.1 (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 CSAC22.1 Canadian Electric
Code (in Canada).
These models may be installed in a bedroom or bed-sitting
room in the U.S.A. and Canada.
1Approvals and
Codes
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.

2Getting Started
Introducing the Heat-N-Glo Gas Fireplaces
Heat-N-Glo direct vent gas fireplaces are designed to oper-
ate 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-install 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 damaged, incomplete, or substitute parts.
The vent system components and trim doors are shipped
in separate packages. The gas logs may be 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
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.

Figure 2. Fireplace Dimensions, Locations,
and Space Requirements
Clearance Requirements
The top, back, and sides of the fireplace are defined by
stand-offs. The minimum clearance to a perpendicular wall
extending past the face of the fireplace is one inch (25 mm).
The back of the fireplace may be recessed 21 1/2 inches
(546 mm) into combustible construction.
For minimum clearances, see the direct vent termination
clearance diagrams on pages 23 and 24 in this manual.
NOTE: When venting with a 900elbow as the first vent com-
ponent, an area 3 above the horizontal vent, the entire width
and depth of the firebox must be free of combustibles (See
Figure 3).
Step 2. Framing the Fireplace
Fireplace framing can be built before or after the fireplace is
set in place. Framing should be positioned to accommo-
date wall coverings and fireplace facing material. The dia-
gram below shows framing reference dimensions.
CAUTION: MEASURE FIREPLACE DIMENSIONS AND

Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use D-series direct vent pipe
components and terminations (see Figures 4 and 5).Approved
vent system components are labeled for identification. This
pipe is tested and listed as an approved component of the
fireplace. The pipe is tested to be run inside an enclosed
wall. There is no requirement for inspection openings at each
joint within the wall. There is no required pitch for horizontal
vent runs. NO OTHER VENTING SYSTEMS OR COMPO-
NENTS MAY BE USED.
Detailed installation instructions are included with each vent
termination kit and should be used in conjunction with this
Installers Guide.
The flame and ember appearance may vary based on the type of
fuel burned and the venting configuration used.
Identifying Vent Components
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 relation-
ships are shown in the venting drawings and tables. Refer to
the diagrams on the next several pages.
NOTE: Two 45° elbows may be used in place of one 90°
elbow. Rise to run ratios in the vent system must be
followed if 45° elbows are used.
This model has 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 attach the
vent system. The starting collar sealing cap must remain on
the starting collar NOT used.

B. Installing Vent Components
1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component to the starting collars
of the fireplace:
 Apply a 3/8 inch (9.5mm) bead of stove cement around
the 5 inch (127mm) fireplace starting collar.
 Make sure that the fireplace rope gasket supplied with
the fireplace seals between the first 8-5/8 inch (219mm)
vent component and the outer fireplace wrap.
 Lock the vent components into place by sliding the con-
centric pipe sections with four (4) equally spaced interior
beads into the fireplace collar or previously installed com-
ponent end with four (4) equally spaced indented sections.
 When the internal beads of each 8-5/8 inch (219mm)
outer pipe line up, rotate the pipe section clockwise about
one-quarter (1/4) turn. The vent pipe is now locked together.
 The first 90° elbow installed in the vent system of a rear
venting fireplace MUST BE in a vertical position.

2. Continue Adding Vent Components
WARNING: INSTALLATION OF THE 7000XLT
FIREPLACE REQUIRES THE USE OF HEAT
SHIELD 570-290 ABOVE THE FIRST 900ELBOW IN
THE VENTING SYSTEM. (HEAT SHIELD NOT RE-
QUIRED FOR 6000XLTB).
Figure 11
To Install the Heat Shield:
1. Determine if the heat shield is required. Do so by mea-
suring the vertical distance between the top horizontal
surface of the elbow to any combustible surface above.
If the distance is more than 4 inches, the heat shield is
NOT required. If it is 4 inches or less, the heat shield IS
REQUIRED. Install per the following steps. See Figure 11.
!
 Continue adding vent components, locking each succeed-
ing component into place.
 Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system.
 90° elbows may be installed and rotated to any point
around the preceding components vertical axis. If an el-
bow does not end up in a locked position with the pre-
ceding component, attach with a minimum of two (2)
sheet metal screws.

CORRECT INCORRECT
2. Fasten the shield in place using the four pilot holes pro-
vided in the part. The shield should be oriented such that
the 13 1/8 inch dimension (longest dimension) is run-
ning in the same direction the elbow is pointing. The
shield should be centered directly above the elbow, and
positioned so that it creates a 1/2 inch airspace between
the shield and the combustible surface. See Figure 12.
3. Install Support Brackets
For Horizontal Runs - The vent system must be supported
every five (5) feet of horizontal run by a horizontal pipe support.
To install support brackets for horizontal runs:
 Place the pipe supports around the vent pipe.
 Nail the pipe supports to the framing members.
Figure 13. Adding Venting Components

20
For Vertical Runs - The vent system must be supported
every eight (8) feet (2.4m) above the fireplace flue outlet by
wall brackets.
To install support brackets for vertical runs:
 Attach wall brackets to the vent pipe and secure the wall
bracket to the framing members with nails or screws.
Figure 14. Installing Support Brackets
4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
NOTE: Model DVK-01TRD does not need an exterior
firestop on an exterior combustible wall.
To install firestops for horizontal runs that pass through
either interior or exterior walls:
 Cut a 12-inch by 12-inch (305mm X 305mm) hole through
the wall.
NOTE: The center of the hole is one (1) inch (25.4mm)
above the center of the horizontal vent pipe.
 Position the firestops on both sides of the hole previ-
ously cut and secure the firestops with nails or screws.
 The heat shields of the firestops MUST BE placed to-
wards the top of the hole.
 Continue the vent run through the firestops.
