. Design, Installation & Location Considerations
WARNING! Risk of Fire Damaged parts could impair safe
operation. Do NOT install damaged, incomplete or substitute
components.
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 fl 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 fl o w
• 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.
CAUTION! If burning shelled field corn, you must use ap-
proved venting specifically designed for corn to prevent
corrosion or degradation. Follow the instructions from the
venting manufacturer.
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 fl 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 fl oor will suport these weights prior to in-
stallation. Add suf cient additional support to meet this
weight requirment prior to installation. The weight of the
appliance is 425 lbs.

mesh and log grates can be removed from a factory-built
r ebox in order to gain minimum insert opening require-
ments.
• Any smoke shelves, shields and baffl es may be removed
from a factory-built rebox if attached with mechanical fas-
teners.
• The metal fl oor of the factory-built rebox may be removed
to facilitate the installation of the insert only when a 1/4
inch (6mm) airspace is provided between the insert and
the fl oor of outer wrap.

A. Venting Termination Minimum Requirements
NOTICE:
Termination must exhaust above air inlet elevation.
• It is recommended that at least 60 inches (1524mm) 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.
• The safest and preferred venting method is to extend the
vent 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
fl o ws 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 recommend in all installations. The
Outside Air Kit must be ordered seperately.
Per national building codes, consideration must be given
to combustion air supply to all combustion appliances.
Failure to supply adequate combustion air for all appli-
ance 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 ori-
ented 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 Te c hnologies strongly recom-
mends:
• I n stalling the pellet vent with a minimum vertical run
of 5 feet (1.52m). Preferably terminating above the
roof line.
• I n stalling 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:
• M aintain speci ed clearances to windows, doors and
air inlets, including air conditioners.
• Ve nts should not be placed below ventilated sof ts.
Run the vent above the roof.
• Av oid venting into alcove locations.
• Ve nts should not terminate under overhangs, decks
or onto covered porches.
• M aintain 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 installa-
tion conditions.
CAUTION
• DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVICING ANOTHER APPLIANCE.
• DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT
OR SYSTEM.
Optional Battery Back-Up
Hearth & Home Technologies supplies an optional battery
back-up system that operates the appliance during power
failure conditions to prevent smoking. In shutdown mode,
the battery back-up will not prevent smoking. See Section
8 for details.
Hearth & Home Te c hnologies assumes no responsibility for,
nor does the warranty extend to, smoke damage caused
by reverse drafting of pellet appliances under shut down or
power failure conditions.

Page 14 7036-135F August 27, 2009
R
Mt. Vernon Pellet Insert (AE)
Negative pressure results from the imbalance of air available
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
• 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.
C. Negative Pressure
Draft is the pressure difference needed to vent an ap-
pliance 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 building
envelope. This helps to produce more draft, especially dur-
ing lighting and die-down of the re.
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
