HighAltitude Installations
U.L. Listed gas appliances are tested and approved with-

the U. S.A. and in Canada.
Wheninstallingthis appliance at an elevation above 2,000
feet, it may be necessary to decrease the input rating by
changingtheexisting 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
between2000and 4500feetinCanada. Iftheheatingvalue
of the gas has been reduced, these rules do not apply. To
identify the proper orifice size, check with the local gas
utility.
Ifinstalling this appliance at anelevation above 4,500 feet
(in Canada), check with local authorities.

2Getting Started
Introducing the Heat & Glo Gas Appliances
Heat & Glo direct vent gas appliances are designed to op-
erate with all combustion air siphoned from outside of the
building and all exhaust gases expelled to the outside.
The information contained in this Owner's Manual, unless
noted otherwise, applies to all models and gas control
systems.Gasappliancediagrams,includingthedimensions,
are shown in this section.
Pre-install Preparation
Thisgasapplianceandits components are tested and safe
when installed in accordance with this Owner's Manual.
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.
TheHeat& Glo Warrantywillbevoided by,andHeat&Glo
disclaims any responsibility for, the following actions:
• Installation of any damaged appliance or vent system
component.
• Modification of the appliance or direct vent system.
• Installation other than as instructed by Heat & Glo.
• Improper positioning of the gas logs or the glass door.
• Installationand/oruseofany component part not manu-
factured and approved by Heat & Glo, not withstanding
anyindependenttestinglaboratory orotherpartyapproval
of such component part or accessory.
ANY SUCH ACTION MAY POSSIBLY CAUSE A FIRE
HAZARD.
When planning a appliance installation, it’s necessary to
determine:
•Where the unit is to be installed.
•Thevent system configuration to be used.
•Gas supply piping.
•Electricalwiring.
•Framingand finishing details.
•Whether optional accessories—devices such as a fan,
wallswitch, or remote control—are desired.
If the appliance is to be installed on carpeting or tile, or on
any combustible material other than wood flooring, the
applianceshouldbeinstalledon a metal or woodpanelthat

Clearance Requirements
The top and back of the appliance are defined by stand-
offs. The minimum clearance to a perpendicular wall
extendingpast thefaceof theapplianceis3 inches (76mm).
The back of the appliance may be recessed 16 1/4 inches
(413mm)into combustible construction.

Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the
gasapplianceand/or itsventsystem.Verticalvents 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
CONSTRUCTIONOFTHECHASEMAYVARYWITH THE
TYPE OF BUILDING. THESE INSTRUCTIONSARE NOT
SUBSTITUTES FOR THE REQUIREMENTS OF LOCAL
BUILDINGCODES.THEREFORE,YOUR LOCAL BUILD-
ING CODES MUST BE CHECKED TO DETERMINE THE
REQUIREMENTSFORTHESESTEPS.
Factory-built appliance 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 out-
sidebuildingenvelopein any manner.
Thismeansthat the walls,ceiling,baseplateand cantilever
floorofthechase should be insulated.Vaporand airinfiltra-
tionbarriersshould be installedinthechaseas per regional
codesfortherestofthe home.Additionally,inregionswhere
cold air infiltration may be an issue, the inside surfaces
maybe sheetrocked and taped for maximumair tightness.
Tofurther prevent drafts,the firestopsshouldbecaulkedto
seal gaps. Gas line holes and other openings should be
caulked or stuffed with insulation. If the appliance is being
installedon acementslab,alayerofplywoodmaybeplaced
