4 Termination Location and Vent Information
A. Vent Termination Minimum Clearances
Figure 4.1
Figure 4.2
INSTALL VENT AT CLEARANCES SPECIFIED BY THE
VENT MANUFACTURER
#1 Preferred method (Figure 4.1)
This method provides excellent venting for normal operation
and allows the stove to be installed closest to the wall. Two
inches from the wall is safe; however, four inches allows
better access to remove the rear panel. The vertical portion of
theventshouldbethreetovefeethigh.Thisverticalsection
will help provide natural draft in the event of a power failure.
Seal pipe joints with silicone or aluminum tape in addition to
the sealing system used by the manufacturer.
Do not place joints within wall pass-through.
#2 Preferred method (Figure 4.2)
This method also provides excellent venting for normal
operation but requires the stove to be installed farther from
the wall. The vertical portion of the vent should be three to
vefeethighandatleast1”fromacombustiblewall.This
vertical section will provide natural draft in the event of a
power failure.
Seal pipe joints with silicone or aluminum tape in addition to
the sealing system used by the manufacturer.
If the stove is installed below grade be sure the vent
termination is at least 12" above grade. The outlet must also
be 1 foot from the house/building.
Do not place joints within wall pass-through.
CAUTION
!
Keep combustible materials (such as grass, leaves,
etc.) at least 3 feet away from the ue outlet on the
outside of the building.

#3 Installing into an existing chimney (Figure 4.3)
This method provides excellent venting for normal operation.
This method also provides natural draft in the event of a
power failure. If the chimney condition is questionable* you
may want to install a liner as in method #7.
In some places in the US and Canada it is required that the
vent pipe extend all the way to the top of the chimney.
*The chimney should be inspected and cleaned before
installing your stove. If you discover that the chimney does
nothaveaclaytilelinerorhascracksorakingofthetile
liner you will need to install a stainless steel liner within

#4 Installing into an existing replace chimney (Figure 4.4)
This method provides excellent venting for normal operation.
This method also provides natural draft in the event of a
power failure. If the chimney condition is questionable* you
may want to install a liner as in method #6.
In some places in the US and Canada it is required that the
vent pipe extend all the way to the top of the chimney.
*The chimney should be inspected and cleaned before
installing your stove. If you discover that the chimney does
nothaveaclaytilelinerorhascracksorakingofthetile

Harman pellet stoves depend on a combustion fan to pull air
through the unit for combustion. The venting system restricts
the ability of the combustion fan to move the required amount
of air through the unit. A system with too much resistance
will result in incomplete combustion, more frequent required
cleaning and poor unit performance. It is always best to
choose a location for the appliance that will result in a venting
system with the shortest equivalent vent length (EVL).
It is best to have your venting system designed by a Harman
authorizeddealerbefore you nalizeyourpurchase of an
appliance.
Equivalent Vent Length: The equivalent vent length for
common pellet vent components are:
• 90° Elbows or Tee: 5 EVL Units
• 45° elbow: 3 EVL Units
• Vertical Pipe or Liner: ½ EVL Unit
• Horizontal Pipe or liner: 1 EVL Unit
The total allowable equivalent vent length is:
• 20 EVL for 3” pellet vent pipe or liner
• 30 EVL for 4” pellet vent pipe or liner
Duetothe potential foryash accumulation inhorizontal
venting sections, the maximum permissible horizontal venting
length is:
• 4 ft. for 3” & 4” pellet vent pipe.

Example: First Floor Installation
A unit is to be installed using 3” Pellet Pipe with 3 feet
of horizontal pipe, a Tee, 10 feet of vertical pipe, a 90°
elbow and a termination cap.
The equivalent vent length is:
3 ft. of Horizontal Pipe (1 x 3 EVL) = 3 EVL
90° Elbow or Tee (1 x EVL) = 5 EVL
10 ft. of Vertical Pipe (10 x .5 EVL) = 5 EVL
90° Elbow or Tee (1 x EVL) = 5 EVL
Termination Cap = 0 EVL
Equivalent Vent Length = 18 EVL
In the example system detailed above, the EVL was 138
which is less than the maximum of 20 EVL for 3” pellet
ventpipe,thusthisisasatisfactoryventingconguration.
Example: Connection to Masonry Chimney
A unit is to be installed using 3” Pellet Pipe with 2 feet of
horizontal pipe, a Tee, 4 feet of vertical pipe, an elbow, a
Tee, 21 feet of vertical liner, and a termination cap.
The equivalent vent length is:
2 ft. of Horizontal Pipe (1 x 2 EVL) = 2 EVL
90° Tee (1 x 5 EVL) = 5 EVL
4 ft. of Vertical Pipe (4 x .5 EVL) = 2 EVL
90° Elbow (1 x 5 EVL) = 5 EVL
90° Tee (1 x 5 EVL) = 5 EVL
21 ft. of Vertical Liner (21 x .5 EVL) = 10.5 EVL
Termination Cap = 0 EVL
Equivalent Vent Length = 29.5 EVL
In the example system detailed above, the EVL was
29.5 which exceeds the maximum of 20 ft. for 3” pellet
vent pipe, thus 3” vent pipe should not be used in this
installation. However, since 4” pipe can support an EVL
up to 30, the use of 4” pipe would create a satisfactory
installation.

Harman® • P-Series Installation Manual_R18 • 2014 - ___ • 06/1817 3-90-436168i
C. Venting & Use of Elbows continued
Note: When the amount of vertical pellet vent pipe in the system exceeds 15 feet, 4” pellet vent pipe should be used.
Note: Equivalent Venting Length decreases as altitude increases.
Note:WhentheHighAltitudeFanBladeisused,themaximumlengthofOutsideAirPipedecreasesto20ft.
Example:
A unit with an EVL of 13, is to be installed at an altitude
of 3,000 feet above sea level.
From the chart to the left, at 3,000 feet of altitude, the
maximum permissible equivalent venting length is 26
feet. Therefore this would be an acceptable installation
with no need to change the combustion blower fan.
However, if the same unit (EVL 13)was to be installed
an altitude of 9,000 feet above sea level, the installation
would no longer be acceptable and the equivalent vent
length of the pipe would have to be reduced for proper
unit operation.

Outside air ex
pipe goes here.
Outside Air:
Hearth & Home Technologies recommend attaching
outside air in all installations, especially lower level and
main oor locations.
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 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.
When the appliance is roof vented: The air intake is best
located on the exterior wall oriented towards the prevailing
wind direction during the heating season.
The outside air connection will supply the demands of the
pellet appliance, but consideration must be given to the
total house demand. House demand may consume some
air needed for the stove, especially during a power failure. 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.

E. Locating Your Appliance & Chimney
Location of the appliance and chimney will affect performance.
• Install through the warm airspace enclosed by the
building envelope. This helps to produce more draft,
especiallyduringlightinganddie-downofthere.
• Penetrate the highest part of the roof. This minimizes the
effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the appliance location relative to oor and
ceiling and attic joists.
G. Negative Pressure
F. Draft
Draft is the pressure difference needed to vent appliances
successfully. When an appliance is drafting successfully, all
combustion by products are exiting the home through the
chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
To measure the draft or negative pressure on your appliance
use a magnahelic or a digital pressure gauge capable of
reading 0 - 1 inches of water column (W.C.).
The appliance should be running on high for at least 15
minutes for the test.
With the stove running on high you should have a negative
pressure equal to or greater than the number given in the
chartbelow.Ifyouhavealowerreadingthanyoundonthe
chart, your appliance does not have adequate draft to burn
the fuel properly.

or the need for outside air. For more information on the draft
test procedure, refer to Page 21
CAUTION
!
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
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
Risk of Asphyxiation! Negative pressure can cause
spillage of combustion fumes and soot.

H. Avoiding Smoke and Odors
Negative Pressure, Shut-down, and Power Failure:
To reduce the probability of back-drafting or burn-back in
the pellet burning appliance during power failure or shut-
down conditions, the stove 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 is recommended in all installations. The
OutsideAirKit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
appliance. 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:
To reduce probability of reverse drafting during shut-
down conditions, Hearth & Home Technologies strongly
recommends:
• Installing the pellet vent with a minimum vertical run of
vefeet,preferablyterminatingabovetheroofline.
• Installing the outside air intake at least four feet 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 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.
Hearth & Home Technologies 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.
Vent Pipe
Besuretouseapprovedpelletventpipewallandceilingpass-throughttingstogothroughcombustiblewallsandceilings.
Besuretouseastartingcollartoattachtheventingsystemtothestove.Thestartingcollarmustbesecuredtotheuestub
with at least three screws, and sealed with high temp silicone caulking.

replaceswithclassAmetalchimneys.
Pellet venting pipe (also known as Type L vent) is constructed of two layers with air space between the layers. This air space
acts as an insulator and reduces the outside surface temperature to allow a clearance to combustibles of only 1 inch. The
sections of pipe lock together to form an air tight seal in most cases; however, in some cases a perfect seal is not achieved.
For this reason and the fact that the P-Series operates with a positive vent pressure, we specify that the joints also be sealed
with silicone.
Where passing through an exterior wall or roof, be sure to use the appropriate pass-through device providing an adequate
vapor barrier. Venting manufacturers generally provide these pass-through devices.
