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.

Figure 2. Fireplace Dimensions and Locations
Constructing the 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 (25 mm).
The metal ends of the fireplace may NOT be recessed into
combustible.

Figure 6. Vent System Components and Termination Kits
Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use SL-series direct vent
pipe components and terminations (see Figures 5 and 6).
Approved vent system components are labeled for identifi-
cation. This pipe is tested and listed as an approved com-
ponent 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 SYS-
TEMS 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.

If the installation is for a termination cap attached directly
to the fireplace, skip to the sections, Install Firestops and
Vent Termination.
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 4 inch (102mm) fireplace starting collar.
 Make sure that the fireplace rope gasket supplied with
the fireplace seals between the first 6-5/8 inch (168mm)
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 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.

to the Starting Collars
2. Continue Adding Vent Components
 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 preced-
ing component, attach with a minimum of two (2) 1/2
sheet metal screws.

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.

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.
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.
To install firestops for horizontal runs that pass through
either interior or exterior walls:
 Cut a 10 X 10 (254mm X 254mm) 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 a 10 x 10 (254mm x 250mm) hole through the ceil-
ing, using the centerpoint previously marked.
 Frame the hole with framing lumber the same size as the
ceiling joists.
Figure 21. 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 20. 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.
NOTE: 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 the local building
codes.

C. Vent Termination
For Horizontal Terminations - To attach and secure the
termination to the last section of horizontal vent:
 Rotate and interlock the ends as described at the begin-
ning of the Installing Vent Components section.
 The termination kit should pass through the wall firestops
from the exterior of the building.
 Adjust the termination cap to its final exterior position on
the building.
WARNING: THE TERMINATION CAP MUST BE
POSITIONED SO THAT THE ARROW IS
POINTING UP.
For roundcap termination kits:
 Use the exterior pipelock hole on the round flange of the
wall firestop to secure the vent pipe in place.
For trapezoidal cap termination kits:
 Using screws secure the cap to the exterior wall through
the flanges in the cap.
