Negative Pressure warning: When negative pressure
is present, an atmospherically vented fireplace (with a
draft hood) may not function properly and it may down
draft. In the case of a gas appliance, spillage of the
combustion gases may occur. This may create a
dangerous carbon monoxide situation in the house.
Step 3
Negative
Pressure
Make-up Air
The causes of negative pressure to a house can include
the following:
• Stack effect in the building.
• Exhaust only appliances (mechanically and
atmospherically vented).
• Inadequate make-up air (which is increasingly
more prevalent in new construction).
NOTE: This fireplace will operate correctly only if
adequate ventilation is provided to allow proper draft to
the fireplace system. Heat & Glo assumes no
responsibility for the improper performance of the
fireplace system caused by inadequate draft due to
environmental conditions, down drafts, tight sealing
construction of the structure, or mechanical exhausting
devices which create a negative air pressure within the
structure where the fireplace is located.
It is recommended that all natural venting non-air tight
gas fireplaces have outside air connected to them. It
is also recommended that the building be
mechanically or passively balanced to allow
atmospherically vented appliances, such as top
vented gas fireplaces with draft hoods, to draft
properly. If the home experiences negative pressure
or is likely to experience negative pressure,
connection to an outside air source is mandatory.
Installing Optional Outside Make-up Air: This unit
is equipped to accept outside air. By using outside
make-up air, the amount of room air used for
combustion will be reduced. It is recommended that
an AK-TV air kit be used with this appliance.
WARNING: IN A NEGATIVE PRESSURE
CONDITION (LIKELY TO OCCUR IN NEW
!
HOMES THAT DO NOT HAVE ADEQUATE
MAKE-UP AIR) THE OUTSIDE AIR KIT
MUST BE INSTALLED TO OBTAIN
PROPER PERFORMANCE AND TO HELP
PREVENT SPILLAGE OF COMBUSTION
GASES.
A 4-inch damper assembly (found in AK-TV Kit) must be
installed to the fireplace. See Figure 5. Attach the
damper assembly to the outer wrap of the fireplace using
sheetmetal screws

Step 4
Installing the
Vent System
A. Vent System Approvals
These fireplaces are approved to use 6-inch (152mm)
diameter B-type vent. B-type vent must be used
when the vent system is within combustible
construction.
These models may also use single wall rigid or flexible
gas vent IF and ONLY IF the vent system is installed
within non-combustible construction such as a masonry
chimney. The same diameters noted above for B-type
vent must be used for single-wall vent. See Figure 6.
The flame and ember appearance may vary based on
the type of fuel burned and the venting configuration used.
B. System Components.
Vent System Configuration
MAXIMUM TOTAL HORIZONTAL RUN = 17 FT.
MINIMUM TOTAL VERTICAL RISE = 10 FT.
MAXIMUM NO. of ELBOWS: 2 - 90o or 4 - 45o
Plan and install the vent system using the parameters
shown above.
WARNING: YOU MUST NOT EXCEED
THESE PARAMETERS.
!
Connect a B-Type vent component to the flue outlet
collar. Look at top inside of the firebox to check that
the vent pipe is attached to the unit. NOTE: It is
required to first attach a straight section of vent
to the unit before attaching a 90o elbow. Avoid
using elbows in the vent system if possible.
A 90-degree elbow CANNOT be attached directly to
the unit. A 45o elbow can be attached directly to
the unit. It must have a straight section of pipe
attached to it for a MINIMUM of 4-feet before a
second 450 elbow to a horizontal run (see Figure 6).
The horizontal component of the vent system must
not exceed a MAXIMUM of 17-feet. The vertical
component of the vent system must exceed a
MINIMUM of 10-feet. Two 450 elbows to vertical can
be used at any length within the 17-feet maximum
horizontal component.
Continue to add vent components, until the vent run is
completed.
WARNING: YOU MUST NOT EXCEED A
TOTAL MAXIMUM HORIZONTAL RUN OF
17 FEET FOR THE ENTIRE VENT SYSTEM.
!
NOTE: The vent termination must be in a vertical
position and the termination cap must be listed
for the vent pipe used.

Step 7
The Gas
Supply Line
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
of 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
(13 mm) 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 the 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 con-
trol valve. NOTE: If substituting for these compo-
nents, please consult local codes for compliance.
• The gas line may be run from either side of the
fireplace provided the hole in the outer wrap does
not exceed 2 inches in diameter and it does not
penetrate the airtight firebox.
• The gap between the supply piping and gas
access hole can be plugged with non-combus-
tible insulation to prevent cold air infiltration.
• Locate the gas line access hole in the outer
casing of the fireplace.
• Remove decorative door by lifting up away to gain
access to the gas control and shut-off valve,
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-corro-
sive leak check solution. Be sure to rinse off all
leak check solution following testing.
WARNING: DO NOT USE AN OPEN
FLAME TO CHECK FOR GAS LEAKS.

Appliance Requirements
This appliance requires that 110-120 VAC be wired to
the junction box. Maintain correct polarity when wiring
the junction box.
Operation using Battery Power
This fireplace has an optional battery operation. The
system is fully functional with the use of two “D” size
batteries without ordinary 110-120 VAC power.
Wiring to the battery pack should be left disconnected
in order to conserve battery life. In the case of a loss of
power, simply connect red and black wire leads to
activate battery power (connect red to red, black to
black). The fireplace can be used as necessary. Once
power (110 VAC) is restored, disconnect red and black
wire leads to extend battery life.

Do not obstruct or modify the air inlet/outlet grilles. When overlapping on both
sides, leave enough space so that the glass door can be 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 installation 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.

TEMPERED
Heat & Glo fireplaces manufactured with tempered glass
may be installed in hazardous locations such as bath-
tub enclosures as defined by the CPSC. The tempered
glass has been tested and certified to the requirements
of ANSI Z97.1-1984 and CPSC 16 CFR 1202. (Safety
Glazing Certification Council SGCC # 1595 and 1597.
Architectural Testing, Inc. Reports 02-31919.01 and 02-
31917.01.)
This statement is in compliance with CPSC 16 CFR
Section 1201.5 “Certification and labeling requirements”
which refers to 15 USC 2063 stating “…Such certifi-
cate shall accompany the product or shall otherwise be
furnished to any distributor or retailer to whom the prod-
uct is delivered.”
Some local building codes require the use of tempered
glass with permanent marking in such locations. Glass
meeting this requirement is available from the factory.
Please contact your dealer or distributor to order.
Placing the Ember Material
Ember material is shipped with this gas fireplace. The
bag labeled Golden Ember (GE-93) is flame colorant
material. The bag labeled Glowing Ember (050-721) is
standard glowing ember material. To place the ember
material:
• Remove wing nuts and glass clips or tension springs
around glass door. Remove glass door from unit.
• Place dime size pieces of ember material about 1/2
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.
• Save the remaining
ember materials for
use during fireplace
servicing. The bag of
embers provided is suf-
ficient for 3 to 5 appli-
cations.
• Replace the wing nut,
glass clips and screws.
• Replace glass door and
a front trim door on unit.
• Hand tighten the wing
nut.

Step 12
Before Lighting
the Fireplace
Before lighting the fireplace, be sure to do the following:
Remove all paperwork and documents from
underneath the fireplace.
Review safety warnings and cautions
• Read the Safety and Warning Information sec-
tion 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. Tampering
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 off 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.
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.
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 US-
ER’S MANUAL FOR ALL CAUTIONS,

PERTAINING TO THE LIGHTING AND OPERA-
TION OF THE FIREPLACE.
