Appliance Certification

The Heat-N-Glo fireplace model discussed in this
Installers Guide has been tested to certification
standards and listed by the applicable laboratories.

CERTIFICATION

Heater

Installation Codes

The fireplace installation must conform to local codes. Before installing the fireplace,
consult the local building code agency to ensure that you are in compliance with all
applicable codes, including permits and inspections.

In the absence of local codes, the fireplace installation must conform to the National
Fuel Gas Code ANSI Z223.1 (in the United States) or the CAN/CGA-B149 Installation
Codes (in Canada). The appliance must be electrically grounded in accordance
with local codes or, in the absence of local codes with the National Electric Code
ANSI/NFPA No. 70 (in the United States), or to the CSA C22.1 Canadian Electric
Code (in Canada).

These models may be installed in a bedroom or bed-sitting room in the U.S.A. and
Canada.

High Altitude Installations

UL 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.

Introducing the
Heat-N-Glo
Fireplaces

Pre-installation
Preparation

Heat-N-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.

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 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.

Getting
Started

The Heat-N-Glo Warranty will be voided by, and Heat­N-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
manufactured 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.

CONTROLS

Constructing the Fireplace Chase

CAUTION:

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.

TREATMENT OF FIRESTOP SP ACERS 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 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-N-Glo recommends that the inside
surfaces be sheetrocked and taped for maximum air
tightness.

Installing the
Fireplace

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 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 MAINTAINED AS SPECIFIED WITHIN THIS
INSTALLERS GUIDE.

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 state of Massachusetts
installation must be performed by a licensed
plumber or gas fitter).

NOTES: 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
(13mm) gas supply line. To install the gas supply line:

• A listed (and State 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.

• A 1/8 inch (3mm) N.P.T. plugged tapping, accessi­ble for test gauge connection, should be provided
for in the gas supply line leading to the unit’s shut­off valve.

• Locate the gas line access hole in the outer
casing of the fireplace.

• 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, use a
soap solution to carefully check all gas connec­tions for leaks.

Orient two “D” size batteries per the diagram on bat­tery pack. Re-install battery pack in the same location.

NOTE

CAUTION

Operation using Battery Power

Wiring to the battery pack is 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.

Optional Accessories

Remote control kits require that 110-120 VAC be
wired to the fireplace junction box.

Wall Switch

Position the wall switch in the desired position on a
wall. Run a maximum of 25 feet (7.8 m) or less of 16
A.W.G. minimum wire and connect it to the fireplace
ON/OFF switch pigtails.

Before lighting the fireplace, be sure to do the

following:

Remove all paperwork and documents from 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 for obstructions.

• Before lighting the fireplace, double-check the unit
for possible obstructions that could be blocking the
vent terminations.

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.

Step 12
Lighting the
Fireplace

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 chemicals used in the paint and logs.

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.
