Getting 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 are shipped in separate
packages. The gas logs may be 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.

Figure 2. 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 MAYVARYWITH 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-
ommendsthatthe insidesurfacesbe sheetrocked andtaped
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.
THE CHASE SHOULD BE CONSTRUCTED SO THAT ALL
CLEARANCES TO THE FIREPLACE ARE MAINTAINED
AS SPECIFIED WITHIN THIS INSTALLERS GUIDE.

Figure 5. Vent System Components and Termination Kits
Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use DVP-series direct vent
pipe components and terminations (see Figures 4 and 5).
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.
This model has 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.

B. Installing Vent Components
After determining which set of starting collars will be used
(top or rear), follow venting instructions accordingly.
Venting Out the Rear Vent
Remove the installed rear seal cap from the rear starting
collars by cutting the strap at each end. (see Figure 19).
Follow the vent configuration tables accordingly.
Remove the insulation from the REAR five inch flue, pull
the heat shield out from outside of the firebox.
WARNING: THE TOP HEAT SHIELD (INSIDE
THE FIREBOX) MUST REMAIN ATTACHED IF
THE VENT SYSTEM IS ATTACHED TO THE
REAR STARTING COLLARS. SEE FIGURE 19.
Venting Out the Top Vent
Remove the two screws in the top vent collar seal cap and
remove the top vent collar seal cap and two pieces of in-
sulation inside the top two starting collars (See Figure 19).
Remove the heat shield from inside the TOP five inch flue
from outside of the firebox.

1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component to the starting collars of
the fireplace:
•Make sure that the fiberglass gasket supplied in the
manual bag seals between the first 8inch (203mm)
vent component and the outer fireplace wrap. Using 2
self-tapping screws from the manual bag secure that
gasket to the outer wrap (see Figure 20).

3. Continue Adding Vent Components
WARNING: INSTALLATION OF THIS FIREPLACE
REQUIRES THE USE OF HEAT SHIELD 570-290
ABOVE THE FIRST 900ELBOW IN THE VENTING
SYSTEM.
Figure 21
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 21.
Figure 22
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 22.

•If the combustible materials are not in place at the time
of install the elbow heat shield may be screwed to the
exhaust pipe (see Figure 23). Cut the tabs as shown
and bend down. Using the screws found in the manual
bag secure the heat shield to the pipe maintaining 3” to
4” between the pipe and shield.
Refer to Cinch Pipe and Termination Cap installation in-
structions.
•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.

5. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
NOTE: Model DVP-TRAP 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 10-inch by 12-inch (254mm 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 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.
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.
