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, fire
officials or authorities having jurisdiction over restrictions,
installation inspection and permits.
Itis a good ideato planyour installationon paper, using exact
measurements for clearances and floor protection, before
actually beginning the installation. Location of the appliance
and chimney will affect performance.
Consideration must be given to:
• Safety, convenience, traffic flow
• 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, soffits, porch roofs, adjacent walls
• Landscaping, vegetation
• Horizontal or vertical vent termination
2. Floor Support
The supporting floor under the appliance must be able to
handle the weight of the appliance, fuel load and the weight
of the chimney.
Ensure that your floor will support these weights prior to
installation. Add sufficient additional support to meet this
weight requirement prior to installation. The weight of the
appliance is 510 lbs. with a full load of fuel the max weight
is 557 lbs.
WARNING
Risk of Fire! Damaged parts could impair safe operation.
Do NOT install damaged, incomplete or substitute com-
ponents.

NOTICE:
Do NOT Terminate Vent:
• In any location that will allow flue gases or soot from en-
tering or staining the building
• In any location which could create a nuisance or hazard
• In any enclosed or semi-enclosed area such as a carport,
garage, attic, crawl space, under a sun deck or porch,
narrow walkway
• Closely fenced area, or any location that can build up
a concentration of fumes such as a stairwell, covered
breezeway, etc.
NOTICE:
Termination must exhaust above air inlet elevation.
• It is recommended that at least 60 inches (1.52m) of vertical
pipe be installed when appliance is vented directly through a
wall. This will create a natural draft, which will help prevent
the possibility of smoke or odor venting into the home during
a power outage.
• It will also keep exhaust from causing a nuisance or hazard
by exposing people or shrubs to high temperatures.
• Thesafestand preferred ventingmethodisto extend thevent
vertically through the roof or above the roof.

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 flows
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 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 backdrafting 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 Configurations
To reduce probability of reverse drafting during shut-down
conditions Hearth & Home Technologies strongly recom-
mends:
• Installing the pellet vent with a minimum vertical run of
5 feet (1.52m). Preferably terminating above the roof
line.
• 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 specified clearances to windows, doors and
air inlets, including air conditioners.
• Vents should not be placed below ventilated soffits.
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 UNIT TO A CHIMNEY FLUE
SERVICING ANOTHER APPLIANCE.
• DO NOT CONNECT TOANY AIR DISTRIBUTION DUCT
OR SYSTEM.

C. Negative Pressure
WARNING
USE ONLY RECOMMENDED VENTING COMPONENTS;
OTHERWISE MAKESHIFT PARTS MAY RESULT IN PROP-
ERTY DAMAGE, PERSONAL INJURY, OR DEATH.
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 heaters
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
• Ensureadequateoutdoorairforallcombustionappliances
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
D. Draft
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 fire.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the chimney
system caused by:
• Inadequate draft due to environmental conditions
• Downdrafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
E. Chimney and Exhaust Connection
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
to6 inch (76-152mm)TopVent OffsetAdapter,useListed double
wall flue connector. AQuadra-Fire OutsideAir Kit (OAK-3) must
be used with manufactured home installations.
3. Residential: The3 inch(76mm)verticalTopVentAdapterKitand
the 3 to 6 inch (76-152mm) Top Vent Offset Adapter are tested
to use 24 gauge single wall flue connector or Listed double wall
flue 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. Vent Assembly to Insert Instructions:
These instructions are for connecting the vent pipe to the
ventassemblyprior to installing the appliancein the fireplace.
a. Unlatch the vent assembly for the exhaust blower and
attach to the vent pipe end using high temperature
silicone and at least three screws.
b. Slide the appliance into place and line up the bent
assembly with the exhaust blower.
c. Make sure the high-temperature gasket is in place.
d. Latch the top vent assembly to the exhaust blower.
6. DO NOT INSTALLAFLUE DAMPER IN THE EXHAUST VENT-
ING SYSTEM OF THIS UNIT.
7. DONOTCONNECTTHISUNITTOACHIMNEYFLUESERVING

8. Disconnect the vent pipe from the appliance to allow removal
of the fireplace insert for the purpose of inspecting the fireplace
insert and the fireplace.
NOTE: All pipe must be welded seam pipe whenever possible.
Seal pipe joints with high temperature silicone (500°F [260°C]
minimum rated only).
WARNING
Risk of Asphyxiation!
Negative pressure can cause spillage of combustion
fumes and soot.
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.
