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.
