Figure 4.1
A . Design, Installation & Location Considerations
1. Appliance Location
NOTICE: Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, re
ofcials or authorities having jurisdiction over restrictions,
installation inspection and permits.
It is a good idea to plan your installation on paper, using exact
measurements for clearances and oor protection, before
actually beginning the installation. Location of the appliance
and chimney will affect performance.
Consideration must be given to:
• Safety, convenience, trafc ow
• Placement of the chimney and chimney connector and to
minimize the use of chimney offsets.
• Place the appliance where there will be a clear passage
for a Listed chimney through the ceiling and roof (vertical)
or through exterior wall (horizontal).
• Installing the required outside air kit will affect the location
of the vent termination.
When locating vent and venting termination, the ideal loca-
tion is to vent above roof line when possible. This minimizes
the affects of wind loading.
Since pellet exhaust can contain ash, soot or sparks, you
must consider the location of:
• Windows
• Air Intakes
• Air Conditioner
• Overhang, softs, porch roofs, adjacent walls
• Landscaping, vegetation
• Horizontal or vertical vent termination
2. Floor Support
The supporting oor under the appliance must be able to
handle the weight of the appliance, fuel load and the weight
of the chimney.
Ensure that your oor will support these weights prior to
installation. Add sufcient additional support to meet this
weight requirement prior to installation. The weight of the
appliance is 426 lbs.
WARNING
Risk of Fire.
Damaged parts could impair safe operation. Do NOT
install damaged, incomplete or substitute components.

B. Avoiding Smoke and Odors
Negative Pressure, Shut-Down and Electrical Power
Failure
To reduce the probability of back-drafting or burn-back in
the pellet appliance during power failure or shut down con-
ditions, it must be able to draft naturally without exhaust
blower operation.
Negative pressure in the house will resist this natural draft if
not accounted for in the pellet appliance installation.
Heat rises in the house and leaks out at upper levels. This
air must be replaced with cold air from outdoors which ows
into lower levels of the house.
Vents and chimneys into basements and lower levels of the
house can become the conduit for air supply and reverse
under these conditions.
Outside Air
An outside air kit (OAK-3) is recommended in all installations
and must be ordered separately.
Per national building codes, consideration must be given to
combustion air supply to all combustion appliances. Failure
to supply adequate combustion air for all appliance demands
may lead to back drafting of those and other appliances.
When the appliance is roof vented (strongly recommended):
The air intake is best located on the exterior wall oriented
towards the prevailing wind direction during the heating
season.
When the appliance is side-wall vented:
The air intake is best located on the same exterior wall as
the exhaust vent outlet and located lower on the wall than
the exhaust vent outlet.
The outside air supply kit can supply most of the demands of
the pellet appliance, but consideration must be given to the
total house demand.
House demand may consume the air needed for the appli-
ance. It may be necessary to add additional ventilation to
the space in which the pellet appliance is located.
Consult with your local HVAC professional to determine the
ventilation demands for your house.
Vent Congurations
When installing a pellet appliance with a horizontal vent con-
guration the frequency of power outages should be consid-
ered:
• Power outages during operation will cause the appliance
to immediately turn off and may create conditions where
smoke will back draft into the house. In order to reduce
the likelihood of smoke back drafting into the house
during a power outage, Hearth and Home Technologies
strongly suggests:
• Installing the pellet venting with a minimum vertical
run of 5 feet (1.52m).
• Installing the outside air kit at least 4 feet (1.22m)
below the vent termination.
To prevent soot damage to exterior walls of the house and to
prevent re-entry of soot or ash into the house:
• Maintain specied clearances to windows, doors and
air inlets, including air conditioners.
• Vents should not be placed below ventilated softs.
Run the vent above the roof.
• Avoid venting into alcove locations.
• Vents should not terminate under overhangs, decks or
onto covered porches.
• Maintain minimum clearance of 12 inches (305mm)
from the vent termination to the exterior wall. If you
see deposits developing on the wall, you may need to
extend this distance to accommodate your installation
conditions.
CAUTION
• DO NOT CONNECT THIS Appliance TO A CHIMNEY
FLUE SERVICING ANOTHER APPLIANCE.
• DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT
OR SYSTEM.

Negative pressure results from the imbalance of air avail-
able for the appliance to operate properly. It can be strongest
in lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water
appliances and other combustion appliances
• Clothes dryers
• Location of return-air vents to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
- Recessed lighting
- Attic hatch
- Duct leaks
To minimize the effects of negative air pressure:
• Install the outside air kit with the intake facing prevailing
winds during the heating season
• Ensure adequate outdoor air for all combustion appliances
and exhaust equipment
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the appliance
• Avoid installing the appliance near doors, walkways or
small isolated spaces
• Recessed lighting should be a “sealed can” design
• Attic hatches weather stripped or sealed
• Attic mounted duct work and air handler joints and seams
taped or sealed
WARNING
Risk of Asphyxiation!
Negative pressure can cause spillage of combustion
fumes and soot.
WARNING
USE ONLY RECOMMENDED VENTING COMPONENTS;
OTHERWISE MAKESHIFT PARTS MAY RESULT IN PROP-
ERTY DAMAGE, PERSONAL INJURY, OR DEATH.
NOTE: The appliance exhaust outlet is designed to ac-
commodate 3 inch venting. Use of 4 inch venting requires
the use of a 3-to-4 inch exhaust vent increaser in addition
to any other venting components needed, sold separate-
ly.
C. Negative Pressure
1. Chimney & Connector:Use 3 or 4 inch (76-102mm)
diameter type “L” or “PL” venting system. It can be vented
vertically or horizontally.
2. Mobile Home: Approved for all Listed pellet vent. If using
the 3 inch (76mm) vertical Top Vent Adapter Kit or the 3
to 6 inch (76-152mm) Top Vent Offset Adapter, use Listed
double wall ue connector. A Quadra-Fire Outside Air Kit
(OAK-3) must be used with manufactured home installa-
tions.
3. Residential: The 3 inch (76mm) vertical Top Vent Adapter
Kit and the 3 to 6 inch (76-152mm) Top Vent Offset Adapter
are tested to use 24 gauge single wall ue connector or
Listed double wall ue connector to Class A Listed metal
chimneys, or masonry chimneys meeting International
Residential Code standards for solid fuel appliances.
4. INSTALL VENT AT CLEARANCES SPECIFIED BY THE
VENT MANUFACTURER.
5. Secure exhaust venting system to the appliance with at
least 3 screws. Also secure all connector pipe joints with
at least 3 screws through each joint.
6. DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST
VENTING SYSTEM OF THIS Appliance.
7. DO NOT CONNECT THIS Appliance TO A CHIMNEY FLUE
SERVING ANOTHER APPLIANCE.
NOTE: All pipe must be welded seam pipe whenever
possible. Seal pipe joints with high temperature silicone
(500°F [260°C] minimum rated only).
E. Chimney and Exhaust Connection
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the chimney
system caused by:
• Inadequate draft due to environmental conditions
• Down drafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
Draft is the pressure difference needed to vent an appli-
ance successfully. When an appliance is drafting suc-
cessfully, all combustion byproducts are exiting the home
through the chimney.
Install through the warm airspace enclosed by the build-
ing envelope. This helps to produce more draft, especially
during lighting and die-down of the re.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
