Getting Started
A. Introducing the Gateway Fireplace
The Gateway fi replace is designed to operate with all ex-
haust gases expelled to the outside.
The information contained in this Installers Guide, unless
noted otherwise, applies to all models and gas control
systems. Gas fi replace diagrams, including the dimensions,
are shown in this section.
CAUTION
Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult local building, fi re offi cials or authorities having jurisdic-
tion about restrictions, installation inspection, and permits.
Pre-install Preparation
This gas fi replace 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 shipped in the fi replace and
must be on unwrapped before fi ring the unit.
Read all of the instructions before starting the
installation. Follow these instructions carefully during
the installation to ensure maximum safety and benefi t.
Failure to follow these instructions will void the owner’s
warranty and may present a fi re hazard.
WARNING
Fire Risk
Explosion Risk
Keep appliance dry.
• Mold or rust may cause odors.
• Water may damage controls.
Warranty
The Heat & Glo Warranty will be voided by, and Heat &
Glo disclaims any responsibility for, the following actions:
• Installation of any damaged fi replace or vent system
component.
• Modifi cation of the fi replace or 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 manufactured 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 fi replace installation, it’s necessary to
determine:
• Where the unit is to be installed.
• The vent system confi guration to be used.
• Gas supply piping.
• Electrical wiring.
• Framing and fi nishing details.
• Whether optional accessories — devices such as a fan,
wall switch, fresh air kit or remote control — are desired.
If the fi replace is to be installed on carpeting or tile, or
on any combustible material other than wood fl ooring, the
fi replace must be installed on a metal or wood panel that
extends the full width and depth of the fi replace.

B. Negative Pressure
WARNING
Asphyxiation Risk.
•
Negative pressure can cause spillage of
combustion fumes and soot.
• Fireplace needs to draft properly for safety.
Draft is the pressure difference needed to vent fi replaces
successfully. Considerations for successful draft include:
• Preventing negative pressure
• Location of fi replace and chimney
Negative pressure results from the imbalance of air avail-
able for the fi replace to operate properly. Causes for this
imbalance include:
• Exhaust fans (kitchen, bath, etc.)
• Install the fresh air kit. Install the intake on the side of
the house towards prevailing winds during the heating
season.
• Ensure adequate outdoor air is supplied for combus-
tion appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are
not located in the immediate vicinity of the fi replace.
• Avoid installing the fi replace near doors, walkways or
small isolated spaces.
• Recessed lighting should be of “sealed can” design;
attic hatches weather stripped or sealed; and attic
mounted duct work and air handler joints and seams
taped or sealed.
• Basement installations should be avoided due to stack
effect. Stack effect creates negative pressure in lower
levels. Hearth & Home Technologies recommends the
use of direct vent fi replaces in basements.
• Range hoods
• Combustion air requirements for furnaces, water heaters and other combustion appliances
• Clothes dryers
• Location of return-air to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks (recessed lighting, attic hatch
opening, duct leaks)
To minimize the effects of negative air pressure, the following must be considered:
Recommended
Location
Marginal
Location
Location
Not
Recommended
Location of the fi replace and chimney will affect perfor-
mance. As shown in Figure 2.1, the chimney should:
• Be installed through the warm space enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fi re.
• Penetrate the highest part of the roof. This minimizes
the effects of wind turbulence.
• Be located away from trees, adjacent structures, uneven roof lines and other obstructions.
Offsets can restrict draft so their use should be minimized.

B. Constructing the Appliance Chase
A chase is a vertical boxlike 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.
Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST
be checked.
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.
Walls, ceiling, base plate and cantilever fl oor of the chase
should be insulated. Vapor and air infi ltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infi ltration may be an issue, the inside surfaces may be
sheetrocked and taped for maximum air tightness.
To further prevent drafts, the wall shield and ceiling
fi restops should be caulked with high temperature caulk
to seal gaps. Gas line holes and other openings should
be caulked with high temp caulk or stuffed with unfaced
insulation. If the appliance is being installed on a cement
slab, a layer of plywood may be placed underneath to
prevent conducting cold up into the room.
C. Clearances
The top, back and sides of the fi replace are defi ned by
standoffs. The minimum clearance to a perpendicular
wall extending past the face of the fi replace is one inch
(25mm). The metal ends of the fi replace may NOT be
recessed into combustible construction.
WARNING
Fire Risk.
Odor Risk.
• Install appliance on hard metal or wood surfaces
extending full width and depth of appliance.
• Do NOT install appliance directly on carpeting,
vinyl, tile or any combustible material other than
wood.
• Do NOT place furniture or any other combustible household objects within 36 inches of the
appliance front.
WARNING
Fire Risk.
• Construct chase to all clearance specifi cations
in manual.
• Locate and install appliance to all clearance
specifi cations in manual.

Vent Information and Diagrams
A. Vent System Approvals
WARNING
Fire Risk.
Asphyxiation Risk.
This appliance requires the specifi ed pipe for
operation.
• Incorrect pipe may cause spillage, condensation
and overheating.
Model GATEWAY is approved to use Duravent 4-inch (102
mm) diameter B-type vent for installations that terminate
vertically. The PV-Flex Series vent pipe is approved for
use in installations that terminate horizontally. This pipe
is tested and listed as an approved component of the
fi replace.
This model may also use single wall rigid or fl exible gas
vent IF and ONLY IF the vent system is installed within
non-combustible construction such as a masonry chimney. The same diameter noted above for B-type vent
must be used for single-wall vent (see Figure 5.1).
For B-type vent the clearance to combustibles is 1-inch all
around the pipe. Follow vent manufacturers REQUIRED
clearances. For PV-Flex the clearances are 1-1/2 in. top
and 1 in. sides and bottom when venting horizontally
and 1 in. on all sides when passing vertically through
combustible materials.
B. System Components
Consult Local Building Code Offi cials and Codes for
proper vent system installations.
Plan and install the vent system using the parameters
shown in this vent system confi guration chart.

The following fi gures are examples of approved venting
conditions. Venting downward (3 feet maximum) is approved, to allow venting below the fl oor. However, only
one downward section is allowed for up to, but not exceeding 3 feet maximum.
Note: It is always better to fi rst attac h a straight se ction of
vent to the unit before attaching an elbow. Avoid using elbows
in the vent system if possible.
