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 are 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.

Clearance Requirements
The top and back of the fireplace are defined by stand-offs.
The minimum clearance to a perpendicular wall extending
past the face of the fireplace is 3 inches (76mm). The back
of the fireplace may be recessed 16 1/4 inches (413mm)
into combustible construction.
Figure 4. Fireplace Dimensions, Locations,
and Space Requirements
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-
ommendsthat theinside surfacesbe sheetrockedand 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.
NOTE: For SL-950TR-C ONLY: When venting with a 900
elbow as the first vent component, an area 3” above the
horizontal vent, the entire width and depth of the firebox
must be free of combustibles (see Figure 5).
*NOTE:If venting with (2) 900elbows off rear of unit
the dimensions C, D, and E, will change.

Step 3. Installing the Vent System
A. Vent System Approvals
These models have 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.
These models use SL-D-series, direct vent components
when using the TOP vent collars. 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.
These models also use DVP-series direct vent components
when using the REAR vent collars.
The flame and ember appearance may vary based on the
type of fuel burned and the venting configuration used.
WARNING: YOU MUST NOT MIX DVP-SERIES
ANDSLD-SERIES COMPONENTS IN ANY VENT
SYSTEM CONFIGURATION.
Identifying Vent Components
Approved vent system components are labeled for identifi-
cation. 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. Figure 8
shows vent system components and terminations.
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. Maximum and minimum rise to run ratios
must always be maintained in the vent system when
using 45° elbows.

Flex Vent
The flex vent must be supported with the spacing between
support intervals not exceeding 4 feet, with no more than ½
inch sag between supports.
A support is required at each change in venting direction,
and in any location where it is necessary to maintain the
necessary clearance to combustibles. A simple “up and out”
installation (Figure 9) requires only enough support to main-
tain the necessary clearance to combustibles. However, the
vent attachment point and the firestop location are consid-
ered to be supports.
