Approvals and
Codes

Appliance Certification

The Heat-N-Glo fireplace models discussed in this Installers
Guide have been tested to certification standards and listed

by the applicable laboratories.

Certification

MODELS: SL-750TRS-C, SL-550TRS-C, SL- 350TRS-C
LABORATORY: Underwriters Laboratories
TYPE: Direct Vent Gas Fireplace Heater
STANDARD: ANSI Z21.88•CSA2.33•UL307B

NOTE: THESE MODELS ARE UL LISTED TO UL307B,
THE STANDARD FOR GAS-BURNING HEATING APPLI­ANCES FOR MANUFACTURED HOMES AND RECRE-

ATIONAL VEHICLES.

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.

High Altitude Installations

U.L. Listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2,000 feet in the
U. S. A. and in Canada.

When installing this appliance at an elevation above 2,000
feet, it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Input
rate should be reduced by 4% for each 1000 feet above a
2000 foot elevation in the U.S.A. or 10% for elevations
between 2000 and 4500 feet in Canada. If the heating value
of the gas has been reduced, these rules do not apply. To
identify the proper orifice size, check with the local gas
utility.

If installing this appliance at an elevation above 4,500 feet
(in Canada), check with local authorities.

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.

Getting Started

Introducing the Heat-N-Glo Gas Fireplaces

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.

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 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.

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 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.

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. 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 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.

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 THA T ALL
CLEARANCES TO THE FIREPLACE ARE MAINTAINED
AS SPECIFIED WITHIN THIS INSTALLERS GUIDE.

Step 1. Locating the Fireplace

Space and clearance requirements for locating a fireplace
within a room (see Figure 4).

Clearance Requirements

The top and back of the fireplace are defined by stand-offs.
The minimum clearance to a perpendicular wall extending
past the face of the fireplace is 3 inches (76mm). The bac k
of the fireplace may be recessed 16 1/4 inches (413mm)
into combustible construction.

The distance from the unit to combustible construction is to
be measured from the unit outer wrap surface to the com­bustible construction, NOT from the screw heads that se­cure the unit together.

Step 2. Framing the Fireplace

Fireplace framing can be built before or after the fireplace is
set in place. Framing should be positioned to accommo­date wall coverings and fireplace facing material. The dia­gram below shows framing reference dimensions.

Framing should be
constructed of 2 X 4
lumber or heavier.

The framing headers
may rest on the
fireplace stand-offs.
