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.
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

For minimum clearances of direct vent termination (see Fig-
ures 25 and 26).
Constructing the Fireplace Chase
A chase is a vertical box-like structure built to enclose the
gas fireplace and/or its vent system. Vertical vents that run
on the outside of a building may be, but are not required to
be, installed inside a chase.
CAUTION: TREATMENT OF FIRESTOP SPACERS AND
CONSTRUCTION OF THE CHASE MAY VARY WITH THE
TYPE OF BUILDING. THESE INSTRUCTIONS ARE NOT
SUBSTITUTES FOR THE REQUIREMENTS OF LOCAL
BUILDING CODES. THEREFORE, YOUR LOCAL BUILD-
ING CODES MUST BE CHECKED TO DETERMINE THE
REQUIREMENTS FOR THESE STEPS.
Factory-built fireplace chases should be constructed in the
manner of all outside walls of the home to prevent cold air
drafting problems. The chase should not break the outside
building envelope in any manner.
This means that the walls, ceiling, base plate and cantilever
floor of the chase should be insulated. Vapor and air infiltra-
tion barriers should be installed in the chase as per regional
codes for the rest of the home. Additionally, Heat-N-Glo rec-
ommends that the inside surfaces be sheetrocked and taped
for maximum air tightness.
To further prevent drafts, the firestops should be caulked to
seal gaps. Gas line holes and other openings should be
caulked or stuffed with insulation. If the unit is being in-
stalled on a cement slab, we recommend that a layer of
plywood be placed underneath to prevent conducting cold
up into the room. Be sure to include spark arrestors for
woodburning units if they are required.
THE CHASE SHOULD BE CONSTRUCTED SO THAT ALL
CLEARANCES TO THE FIREPLACE ARE MAINTAINED
AS SPECIFIED WITHIN THIS INSTALLERS GUIDE.
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 (25mm).
The metal ends of the fireplace may NOT be recessed into
combustible construction.

Figure 4. Framing Dimensions*
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
VERIFY FRAMING METHODS AND WALL COVERING
DETAILS BEFORE FRAMING.
Shows center of 10 x 10 vent framing holes.
The center of the hole is 1 inch (25.4mm)
above the center of the horizontal vent pipe.
37 1/8
(943mm)
Framing should be constructed
of 2 X 4 lumber or heavier.
WARNING: FRAMING DIMENSIONS ASSUME
USE OF 1/2 INCH THICK WALL COVERING
MATERIALS ON EXTERIOR OF FRAMING ONLY
AND NO SHEET ROCK ON INTERIOR OF FRAMING.

Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use SL-series direct
vent pipe components and terminations. Approved
vent system components are labeled for identifica-
tion. 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 drawing below shows
vent system components and terminations.
The flame and ember appearance may vary based
on the type of fuel burned and the venting configura-
tion 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 relationships are shown
in the venting drawings and tables. Refer to the dia-
grams 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.
NOTE: PIPES OVERLAP 1-3/8 INCHES (34.93mm) AT EACH JOINT.

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 interi-
or beads into the fireplace collar or previously installed com-
ponent end with four (4) equally spaced indented sections.
 When the internal beads of each 6-5/8 inch (168mm)
outer pipe line up, rotate the pipe section clockwise about
one-quarter (1/4) turn. The vent pipe is now locked together.
!
WARNING: A 3/8 INCH (9.5 MM) BEAD OF
STOVE CEMENT MUST BE PLACED AROUND
THE 4 INCH (102MM) FIREPLACE STARTING COL-
LAR BEFORE ATTACHING THE FIRST VENT COM-
PONENT. FAILURE TO SEAL THIS JOINT MAY
CAUSE THE FIREPLACE TO OPERATE IMPROPER-
LY. SEE FIGURE 16.

If the installation is for a termination cap attached directly
to the fireplace, skip to the sections, Install Firestops and
Vent Termination.
2. Continue Adding Vent Components
To continue adding vent components in accordance with
the pre-planned vent system configuration:
 Ensure that each succeeding vent component is securely
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
elbow does not end up in a locked position with the pre-
ceding component, attach with a minimum of two (2) sheet
metal screws. Continue adding vent components, locking
each succeeding component into place (see Figure 17).

3. Install Support Brackets
For Horizontal Runs -The vent system must be sup-
ported 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.
To install firestops for horizontal runs that pass through
either interior or exterior walls:
 Cut a 10-inch by 10-inch (254mm X 254mm) hole through
the wall. 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.
Figure 18. 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 SLK-01TRD does not need an exterior
firestop on an exterior combustible wall. The firestop is
built into the cap.

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.
NOTE: There must be NO INSULATION or other
combustibles inside the framed firestop opening.

24
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 10-inch x 10-inch (254mm x 254mm) hole through
the ceiling, using the centerpoint previously marked.
 Frame the hole with framing lumber the same size as the
ceiling joists.
Figure 22. Ceiling Firestop (Ceiling Side)
If the area above the ceiling is NOT an attic, position and
secure the ceiling firestop on the ceiling side of the previously
cut and framed hole.
Figure 21. 10" x 10" Hole & New Framing Members
If the area above the ceiling IS an attic, position and secure
the firestop on top of the previously framed hole.
Figure 23 shows an attic installation. Keep insulation away
from the vent pipe at least 1 inch (25mm).
While it is not mandatory, it is strongly recommended that
an attic insulation shield be used whenever insulation can
come in contact with the vent pipe. Follow your local building
codes.
