Getting 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 Installers Guide, unless
noted otherwise, applies to all models and gas control
systems. Gas appliance diagrams, including the dimensions,
are shown in this section.

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 & Glo Warranty will be voided by, and Heat & 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.
• Installation and/or use of any component part not manu-
factured and approved by Heat & 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 appliance 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 appliance is to be installed on carpeting or tile, or on
any combustible material other than wood flooring, the
appliance should be installed on a metal or wood panel that
extends the full width and depth of the appliance.

Installing the Appliance
Step 1. Locating the Appliance
Space and clearance requirements for locating a appliance
within a room (see Figure 4).
Minimum Clearances
from the Appliance to Combustible Materials
For minimum clearances, see the direct vent termination
clearance diagrams in Figures 29 and 30 in this manual.

Top .................................. 2 1/2 ............63.7
Bottom ..............................1/2............... 13
Sides ................................. 1 ................ 25
* The clearance to the ceiling is measured from the top
of the unit, excluding the standoffs (see Figure 37).
The distance from the unit to combustible construction is to
be measured from the unit outer wrap surface to the com-
bustible construction, NOT from the screw heads that se-
cure the unit together.

Clearance Requirements
The top and back of the appliance are defined by stand-
offs. The minimum clearance to a perpendicular wall
extending past the face of the appliance is 3 inches (76mm).
The back of the appliance may be recessed 16 1/4 inches
(413mm) into combustible construction.
Figure 4. Appliance Dimensions, Locations,
and Space Requirements
Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the
gas appliance 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 BUILD-
ING CODES MUST BE CHECKED TO DETERMINE THE
REQUIREMENTS FOR THESE STEPS.
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-
side 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 infiltra-
tion barriers should be installed in the chase as per regional
codes for the rest of the home. Additionally, in regions where
cold air infiltration may be an issue, the inside surfaces
may 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 in-
stalled on a cement slab, a layer of plywood may be placed
underneath to prevent conducting cold up into the room.
THE CHASE SHOULD BE CONSTRUCTED SO THAT ALL
CLEARANCES TO THE APPLIANCE ARE MAINTAINED
AS SPECIFIED WITHIN THIS INSTALLERS GUIDE.

Figure 5. Framing Dimensions
Framing should be
constructed of 2 X 4
lumber or heavier.
The framing headers
may rest on the
appliance stand-offs.
Step 2. Framing the Appliance
Appliance framing can be built before or after the appliance
is set in place. Framing should be positioned to accommo-
date wall coverings and appliance facing material. The dia-
gram below shows framing reference dimensions.
CAUTION: MEASURE APPLIANCE DIMENSIONS AND
VERIFY FRAMING METHODS AND WALL COVERING
DETAILS BEFORE FRAMING.
