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.

2Getting Started
Introducing the Hearth Technologies Gas
Fireplace
Hearth Technologies direct vent gas fireplaces are designed
to operate 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 sys-
tems. Gas fireplace diagrams, including the dimensions,
are shown in this section.
Pre-installation 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, par-
ticularly 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 may be packaged
separately and must be field installed.
Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefit.
Failure to follow these instructions will void the own-
er’s warranty and may present a fire hazard.
The Hearth Technologies Warranty will be voided by, and
Hearth Technologies 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 Hearth Technolo-
gies.
• Improper positioning of the gas logs or the glass door.
• Installation and/or use of any component part not manu-
factured and approved by Hearth Technologies, not with-
standing 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, 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 back of the fireplace may be recessed 21 1/2 inches
(546 mm) into combustible construction.
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 cantile-
ver floor of the chase should be insulated. Vapor and air
infiltration barriers should be installed in the chase as per
regional codes for the rest of the home. Additionally, Heat-
N-Glo recommends 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.

Step 3. Installing the Vent System
A. Vent System Approvals
This model is approved to use D-series direct vent pipe
components and terminations (see Figures 4 and 5). Ap-
proved vent system components are labeled for identifica-
tion. This pipe is tested and listed as an approved compo-
nent of the fireplace. The pipe is tested to be run inside an
enclosed wall. There is no requirement for inspection open-
ings at each joint within the wall. There is no required pitch
for horizontal vent runs. NO OTHER VENTING SYSTEMS
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 appear-
ance 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.

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 6) 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.

1. Attach the First Vent Component to Starting Collars
To attach the first vent component to the starting collars
ofthe fireplace:
• Apply a 3/8 inch (9.5mm) bead of stove cement around
the 5 inch (127mm) fireplace starting collar.
• Make sure that the fiberglass gasket supplied with the
fireplacesealsbetween thefirst8-5/8 inch(219mm)vent
componentand theouter fireplacewrap.
• Lockthe vent componentsinto place bysliding thecon-
centricpipe sectionswith four(4)equally spacedinterior
beadsinto the fireplacecollar orpreviously installedcom-
ponentendwithfour(4)equallyspacedindentedsections.
• When the internal beads of each 8-5/8 inch (219mm)
outer pipe line up, rotate the pipe section clockwise
aboutone-quarter(1/4) turn.Thevent pipeisnow locked
together.
• The first 90° elbow installed in the vent system of a
rear venting fireplace MUST BE ina verticalposition.

2. Continue Adding Vent Components
WARNING: INSTALLATION OF THIS FIRE-
PLACE REQUIRES THE USE OF A HEAT
SHIELD ABOVE THE FIRST 900ELBOW IN THE
VENTING SYSTEM.
Figure 20.
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
surfaceof the elbowto any combustiblesurface 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.Installperthefollowingsteps.SeeFigure20.

• Continueaddingventcomponents,lockingeachsucceed-
ing component into place.
• Ensurethat eachsucceedingvent componentissecure-
ly fitted and locked into the preceding component in the
vent system.
• 90° elbows may be installed and rotated to any point
aroundthe precedingcomponent’s verticalaxis. Ifan 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.

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.
Figure 24. 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 DVK-01TRD 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 12-inch by 12-inch (305mm 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 11-inch X 11-inch (280mm X 280mm) hole through
the ceiling, using the centerpoint previously marked.
• Frame the hole with framing lumber the same size as the
ceiling joists.
Figure 28. 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 27. 11" x 11" 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).
