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: 7000XLS, 6000XLSB
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

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.

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). Ap-
proved vent system components are labeled for identifica-
tion. This pipe is tested and listed as an approved compo-
nent of the fireplace. The pipe is tested to be run inside an
enclosed wall. There is no requirement for inspection open-
ings at each joint within the wall. There is no required pitch
for horizontal vent runs. 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.
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 in-
clude one, two, or three 90° elbow assemblies. The rela-
tionships of vertical rise to horizontal run in vent configura-
tions using 90° elbows MUST BE strictly adhered to. The
rise to run relationships 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.

B. Installing Vent Components
The glass must be taken off again for positioning the logs
when the unit is finally installed in place and finished around
it. Re-install the glass door. Attach vent system to the top
starting collars.
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 7000XLS
FIREPLACE REQUIRES THE USE OF HEAT
SHIELD 570-290 ABOVE THE FIRST 900ELBOW IN
THE VENTING SYSTEM THAT MAKES A TRANSI-
TION FROM VERTICAL TO HORIZONTAL. (HEAT
SHIELD NOT REQUIRED FOR 6000XLSB).
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.
Figure 12
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

18
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.

For Vertical Runs - One ceiling firestop is REQUIRED at
the hole in each ceiling through which the vent passes.
To install firestops for vertical runs that pass through ceilings:
 Position a plumb bob directly over the center of the verti-
cal vent component.
 Mark the ceiling to establish the centerpoint of the vent.
 Drill a hole or drive a nail through this centerpoint.
 Check the floor above for any obstructions, such as wir-
ing or plumbing runs.
 Reposition the fireplace and vent system, if necessary,
to accommodate the ceiling joists and/or obstructions.
 Cut an 11-inch X 11-inch (280mm X 280mm) hole through
the ceiling, using the centerpoint previously marked.
 Frame the hole with framing lumber the same size as the
ceiling joists.

For Vertical Terminations - To locate the vent and install
the vent sections:
 Locate and mark the vent centerpoint on the underside
of the roof, and drive a nail through the centerpoint.
 Make the outline of the roof hole around the centerpoint
nail.
 The size of the roof hole framing dimensions depend on the
pitch of the roof. There MUST BE a 1-inch (25.4mm) clear-
ance from the vertical vent pipe to combustible materials.
 Mark the roof hole accordingly.
 Cover the opening of the installed vent pipes.
 Cut and frame the roof hole.
 Use framing lumber the same size as the roof rafters
and install the frame securely. Flashing anchored to the
frame must withstand heavy winds.
 Continue to install concentric vent sections up through
the roof hole (for inside vent installations) or up past the
roof line until you reach the appropriate distance above
the roof (for outside terminations).
WARNING: MAJOR U.S. BUILDING CODES
SPECIFY MINIMUM CHIMNEY AND/OR
VENT HEIGHT ABOVE THE ROOF TOP. THESE MIN-
IMUM HEIGHTS ARE NECESSARY IN THE INTER-
EST OF SAFETY. SEE THE FOLLOWING DIAGRAM
FOR MINIMUM HEIGHTS, PROVIDED THE TERMI-
NATION CAP IS AT LEAST TWO (2) FEET FROMA
VERTICAL WALL AND 2-FEET BELOW A HORIZON-
TAL OVERHANG.
NOTE: This also pertains to vertical vent systems in-
stalled on the outside of the building.

To seal the roof hole, and to divert rain and snow from the
vent system:
 Attach a flashing to the roof using nails, and use a non-
hardening mastic around the edges of the flashing base
where it meets the roof.
 Attach a storm collar over the flashing joint to form a
water-tight seal. Place non-hardening mastic around the
joint, between the storm collar and the vertical pipe.
 Slide the termination cap over the end of the vent pipe
and rotate the pipe clockwise 1/4 turn.

Step 5. The Gas Control System
WARNING: THIS UNIT IS NOT FOR USE WITH
SOLID FUEL.
The type of gas control system used with this model is Stand-
ing Pilot Ignition.
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.

Figure 25. Gas Supply Line
 Insert insulation from the outside of the fireplace and
pack the insulation tightly to totally seal between the
pipe and the outer casing.
 At the gas line access hole the gap between the supply
piping and gas access hole can be plugged with non-
combustible insulation to prevent cold air infiltration.
Step 6. The Gas Supply Line
NOTE: Have the gas supply line installed in accordance
with local building codes by a qualified installer
approved and/or licensed as required by the locality.
NOTE: Before the first firing of the fireplace, the gas
supply line should be purged of any trapped air.
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.
 The gas line may be run from either side of the fireplace
provided the hole in the outer wrap does not exceed 2 in
diameter and it does not penetrate the actual firebox.
 Open the fireplace lower grille, insert the gas supply line
through the gas line hole, and connect it to the shut-off
valve.
 When attaching the pipe, support the control so that the
lines are not bent or torn.
 After the gas line installation is complete, use a soap
solution to carefully check all gas connections for leaks.
WARNING: DO NOT USE AN OPEN FLAME
TO CHECK FOR GAS LEAKS.

Step 7. Gas Pressure Requirements
Pressure requirements for Heat-N-Glo gas fireplaces
are shown in the table below.
Pressure Natural Gas Propane
Minimum 5.0 inches 11.0 inches
Inlet Pressure w.c. w.c.
Maximum Inlet 14.0 inches 14.0 inches
Gas Pressure w.c. w.c.
Manifold 3.5 inches 10.0 inches
Pressure w.c. w.c.
A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping is
provided on the inlet and outlet side of the gas control for a
test gauge connection to measure the manifold pressure.
Use a small flat blade screwdriver to crack open the screw
in the center of the tap. Position a rubber hose over the tap
to obtain the pressure reading.
The fireplace and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing of the system at test pressures in
excess of one-half (1/2) psig (3.5 kPa).
The fireplace must be isolated from the gas supply piping
system by closing its individual shut-off valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than one-half (1/2) psig (3.5 kPa).
