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

MODEL: CFX-DA
LABORATORY: Underwriters Laboratories
TYPE: Direct Vent Gas Fireplace Heaters
STANDARD: ANSI Z21.50•CGA2.22

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).

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.

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.

This model MUST use D-Series Direct Vent Compo­nents and Termination Kits (as indicated in this guide)
for exhausting flue gases AND model AK-CFX Air Kit
for combustion air. See venting section for details.

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.

This unit is designed to operate from a wall switch (see
wiring diagram on page 21) or a remote control. 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 re-

mote control, extrusion doors or arch doors —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.
