Getting Started
Introducing the Heat & Glo Gas Fireplaces
Heat & Glo 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
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 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 & Glo Warranty will be voided by , and Heat & 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 & Glo.
• Improper positioning of the gas logs or the glass door.
• Installation and/or use of any component part not manufactured and approved by Heat & 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.

Constructing the Fireplace Chase
A chase is a vertical box-like structure built to enclose the
gas fireplace and/or its vent system. V ertical vents that run
on the outside of a building may be, but are not required to
be, installed inside a chase.
CAUTION: TREA TMENT OF FIRESTOP SPACERS AND
CONSTRUCTION OF THE CHASE MA Y V ARY WITH THE
TYPE OF BUILDING. THESE INSTRUCTIONS ARE NOT
SUBSTITUTES FOR THE REQUIREMENTS OF LOCAL
BUILDING CODES. THEREFORE, YOUR LOCAL BUILDING 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
infiltration barriers should be installed in the chase as per
regional codes for the rest of the home. Additionally , Heat &
Glo recommends that the inside surfaces be sheetrocked
and taped for maximum air tightness.
T o further prevent drafts, the firestop s should be caulked to
seal gaps. Gas line holes and other openings should be
caulked or stuffed with insulation. If the unit is being installed 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 MAINT AINED
AS SPECIFIED WITHIN THIS INST ALLERS GUIDE.
Step 1. Locating the Fireplace
The following diagram shows space and clearance requirements for locating a fireplace within a room.
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 12” (304.8 mm).
The back of the fireplace may be recessed 17 1/2” (437.5 mm)
into combustible construction.

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 identification. 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. NO OTHER VENTING SYS-
TEMS OR COMPONENTS MA Y 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.
VERTICAL
TERMINATION
Identifying Vent Component s
The vent systems installed on this gas fireplace may include one, two, or three 90° elbow assemblies. The relationships of vertical rise to horizontal run in vent configurations 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.

4. 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.
T o install firestops for vertical runs that pass through ceilings:
• Position a plumb bob directly over the center of the vertical 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 wiring 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.

For Vertical Terminations - To locate the vent and install
the vent sections:
• Locate and mark the vent centerpoint on the underside
of the roof, and drive a nail through the centerpoint.
• Make the outline of the roof hole around the centerpoint
nail.
• The size of the roof hole framing dimensions depend on the
pitch of the roof. There MUST BE a 1-inch (25.4mm) clearance from the vertical vent pipe to combustible materials.
• Mark the roof hole accordingly.
• Cover the opening of the installed vent pipes.
• Cut and frame the roof hole.
• Use framing lumber the same size as the roof rafters
and install the frame securely . Flashing anchored to the
frame must withstand heavy winds.
• Continue to install concentric vent sections up through
the roof hole (for inside vent installations) or up past the
roof line until you reach the appropriate distance above
the roof (for outside terminations).
• Attach a storm collar over the flashing joint to form a
water-tight seal. Place non-hardening mastic around the
joint, between the storm collar and the vertical pipe.
• Slide the termination cap over the end of the vent pipe
and snap into place.

Step 7. The Gas Supply Line
Step 8. Gas Pressure Requirements
NOTE: Have the gas supply line installed in accordance
with local building codes by a qualified installer approved and/or licensed as required by the locality . (In
the Commonwealth o f Massachusetts installation must
be performed by a licensed plumber or gas fitter).
NOTE: Before the first firing of the fireplace, the gas
supply line should be purged of any trapped air.
NOTE: Consult local building codes to properly size
the gas supply line leading to the 1/2 inch (13mm)
hook-up at the unit.
This gas fireplace is designed to accept a 1/2 inch
(13 mm) gas supply line. To install the gas supply line:
• A listed (and Commonwealth of Massachusetts approved)
1/2 inch (13mm) tee-handle manual shut-off valve and a
listed flexible gas connector are connected to the 1/2
inch (13mm) inlet of the control valve. NOTE: If substituting for these components, please consult local codes
for compliance.
• Locate the gas line access hole in the outer casing of
the fireplace.
• The gas line may be run from either side of the fireplace
provided the hole in the outer wrap does not exceed 2 1/2”
in diameter and it does not penetrate the actual firebox.
• The gap between the supply piping and gas access hole
can be plugged with non-combustible insulation to prevent cold air infiltration.
• Open the fireplace lower grille, insert the gas supply line
through the gas line hole, and connect it to the shut-off valve.
• When attaching the pipe, support the control so that the
lines are not bent or torn.
• After the gas line installation is complete, all connections must be tightened and checked for leaks with a
commercially-available, non-corrosive leak check solution. Be sure to rinse off all leak check solution following
testing.
Pressure requirements for Heat & Glo gas fireplaces are
shown in the table below .
Pressure Natural Gas Propane
Minimum 5.0 inches 11.0 inches
Inlet Pressure w.c. w.c.
Maximum Inlet 14.0 inches 14.0 inches
Gas Pressure w.c. w.c.
Manifold 3.5 inches 10.0 inches
Pressure w.c. w.c.
A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping is
provided on the inlet and outlet side of the gas control for a
test gauge connection to measure the manifold pressure.
Use a small flat blade screwdriver to crack open the screw
in the center of the tap. Position a rubber hose over the tap
to obtain the pressure reading.
The fireplace and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing of the system at test pressures in
excess of one-half (1/2) psig (3.5 kPa).
The fireplace must be isolated from the gas supply piping
system by closing its individual shut-off valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than one-half (1/2) psig (3.5 kPa).
WARNING: DO NOT USE AN OPEN FLAME TO
!
CHECK FOR GAS LEAKS.
• At the gas line access hole, use insulation to re-pack
the space around the gas pipe.
• Insert insulation from the outside of the fireplace and
pack the insulation tightly to totally seal between the
pipe and the outer casing.

Step 1 1. Inst alling T rim, Logs,
and Ember Material
Installing the Trim
Combustible materials may be brought up to the specified
clearances on the side and top front edges of the fireplace,
but MUST NEVER overlap onto the front face. The joints
between the finished wall and the fireplace top and sides
can only be sealed with a 300° F . (149° C) minimum sealant.
WARNING: WHEN FINISHING THE FIREPLACE,
!
NEVER OBSTRUCT OR MODIFY THE AIR INLET/
OUTLET GRILLES IN ANY MANNER.
Install optional marble and brass trim surround kits as
desired. Marble, brass, brick, tile, or other non-combustible
materials can be used to cover up the gap between the
sheet rock and the fireplace.
Do not obstruct or modify the air inlet/outlet grilles. When
overlapping on both sides, leave enough space so that the
bottom grille can be lowered and the trim door removed.
Positioning the Logs
If the gas logs have been factory installed they should not
need to be positioned. If the logs have been packaged
separately, refer to the instructions that accompany the
logs. Save the log instructions with this manual.
If sooting occurs, the logs might need to be repositioned
slightly to avoid excessive flame impingement.
Placing the Ember Material
• Save the remaining ember materials for use during fireplace servicing.
• Replace the glass door and a front trim door on the unit.
• Pull out and latch the glass clips into the groove on the
glass frame.

Ember material is shipped with this gas fireplace. T o place
the ember material:
• Pull the four glass latches out of the groove on the glass
frame. Remove glass door from the unit (see Figure 33).
• Embers CANNOT be placed directly over ports. Care
should be taken not to cover the lighting trail of ports
(from back to front).
• Place dime size pieces of mineral wool embers about 1/2
Î
inch apart near port holes in burner top. Do NOT press
embers into burner ports. Cover the top of the burner
with a single layer of ember material. For best performance do NOT place embers on the ports at the rear of
the burner (Figure 33). Failure to follow this procedure
will likely cause lighting and sooting problems.

screws (2) that secure it behind the burner surface. Slide
the adjustable shutter towards the rear of the fireplace
(closed position). Lift the burner up and towards you to
remove.

Step 12. Before Lighting the Fireplace
Before lighting the fireplace, be sure to do the following:
Remove all paperwork from underneath the fireplace.
Review safety warnings and cautions
• Read the Safety and Warning Information section at
the beginning of this Installers Guide.
Double-check for gas leaks
• Before lighting the fireplace, double-check the unit for
possible gas leaks.
Double-check vent terminations and front grilles for
obstructions.
• Before lighting the fireplace, double-check the unit for
possible obstructions that could be blocking the vent terminations or the front grilles.
Double-check for faulty components
• Any component that is found to be faulty MUST BE replaced with an approved component. T ampering with the
fireplace components is DANGEROUS and voids all warranties.
A small amount of air will be in the gas supply lines. When
first lighting the fireplace, it will take a few minutes for the
lines to purge themselves of this air. Once the purging is
complete, the fireplace will light and will operate normally.
Subsequent lightings of the fireplace will not require this
purging of air from the gas supply lines, unless the gas
valve has been turned to the OFF position, in which
case the air would have to be purged.
NOTE: The fireplace should be run 3 to 4 hours on the initial
start-up. Turn it of f and let it cool completely. Remove and
clean the glass. Replace the glass and run the fireplace for
an additional 8 hours. This will help to cure the products
used in the paint and logs.
Air Shutter Setting
This fireplace has an adjustable air shutter (which controls
the primary air) factory set for the minimum vertical vent run
(see Figure 36). If your installation has more than the
minimum required vertical vent length, adjustment of the air
shutter may be necessary to obtain optimal flame
appearance. This should be adjusted by a qualified
installer at the time of installation.
The air shutter handle has a gap maintainer clip factory
installed which needs to be removed to make any
adjustments. By pushing the air shutter handle in, you will
be closing the air shutter. Care should be taken when
adjusting the air shutter so as not to cause the fireplace to
soot. If sooting occurs the air shutter will need to be opened
by pulling the handle out.
Step 13. Lighting the Fireplace
You’ve reviewed all safety warnings, you’ve checked the
fireplace for gas leaks, you know the vent system is
unobstructed, and you’ve checked for faulty components.
Now you’re ready to light the fireplace.
WARNING: PLEASE REFER TO THE USER’S
!
MANUAL FOR ALL CAUTIONS, SAFETY,
AND WARNING INFORMATION PERTAINING TO
THE LIGHTING AND OPERATION OF THE
FIREPLACE.
After the Installation
LEAVE THIS INSTALLA TION MANUAL WITH
!
THE APPLIANCE FOR FUTURE REFERENCE.
Step 14. Climate Control
During this break-in period it is recommended that some
windows in the house be opened for air circulation. This will
help avoid setting off smoke detectors, and help eliminate
any odors associated with the fireplace’s initial burning.
