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
systemwiththeshortestequivalentventlength(EVL).
It is best to have your venting system designed by a Harman
authorizeddealerbeforeyounalize 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
Duetothepotentialfor y ash accumulation in horizontal
ventingsections,themaximumpermissiblehorizontalventing
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:
3ft.ofHorizontalPipe(1x3EVL) =3EVL
90°ElboworTee(1xEVL) =5EVL

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:
2ft.ofHorizontalPipe(1x2EVL) =2EVL
90°Tee(1x5EVL) =5EVL
4ft.ofVerticalPipe(4x.5EVL) =2EVL

90°Tee(1x5EVL) =5EVL
21ft.ofVerticalLiner(21x.5EVL) =10.5EVL
TerminationCap =0EVL
EquivalentVentLength =29.5EVL
In the example system detailed above, the EVL was
29.5whichexceedsthemaximumof20ft.for3”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.

C. Venting & Use of Elbows continued
Note:Whentheamountofverticalpelletventpipeinthesystemexceeds15feet,4”pelletventpipeshouldbeused.
Note: Equivalent Venting Length decreases as altitude increases.
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:
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,
mayleadtoback-draftingofthoseandotherappliances.

When the appliance is roof vented: The air intake is best
locatedontheexteriorwallorientedtowardstheprevailing
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
Locationoftheapplianceandchimneywillaectperformance.
• Install through the warm airspace enclosed by the
building envelope. This helps to produce more draft,
especiallyduringlightinganddie-downofthere.
• Penetrate the highest part of the roof. This minimizes the
eectsofwindloading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimizetheuseofchimneyosets.
• Consider the appliance location relative to oor and
ceiling and attic joists.
G. Negative Pressure

successfully. When an appliance is drafting successfully, all
combustionbyproductsareexiting 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
reading0-1inchesofwatercolumn(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

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:
• Exhaustfans(kitchen,bath,etc.)
• Range hoods
• Combustion air requirements for furnaces, water heaters
and other combustion appliances
• Clothes dryers
• Locationofreturn-airventstofurnaceorairconditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
-Recessedlighting
-Attichatch
-Ductleaks
Tominimizetheeectsofnegativeairpressure:
• Install the outside air kit with the intake facing prevailing
winds during the heating season
• Ensure adequate outdoor air for all combustion
appliancesandexhaustequipment
• 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.
WARNING

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
withoutexhaustbloweroperation.Negativepressureinthe
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
airmustbereplacedwithcoldairfromoutdoors,whichows
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
OutsideAirKitmustbeorderedseparately.
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.

thantheexhaustventoutlet.
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 Pipe
Be sure to use approved pellet vent pipe wall and ceiling
pass-throughttingstogothroughcombustiblewallsand
ceilings. Be sure to use a starting collar to attach the venting
system to the stove. The starting collar must be secured to
theuestubwithatleastthreescrews,andsealedwithhigh
temp silicone caulking.
4” stainless steel ex vent piping is only allowed for use
in masonry replaces and chimneys orfactory built wood
burningreplaceswithclassAmetalchimneys.
Pelletventingpipe(alsoknownasTypeLvent)isconstructed
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. Follow venting manufacturer’s
recommendations for sealing pipe joints.

Vent Congurations:
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
vefeet,preferablyterminatingabovetheroofline.
• Installing the outside air intake at least four feet below
the vent termination.

F. Low Draft Voltage Adjustment
Theseunitsarepre-testedatthe factory with exactly 120
VAC, 60 Hz. They are checked and adjusted for rebox
tightness, gasket leakage, motor operation and igniter
operation.TheP-Series is then factory set at a mid-point
adjustment and in most cases will not need any adjustments.
NOTE: The factory low draft setting may not be correct
for the unit’s permanent installation conditions.
Thecontrolboard ontheP-Seriesis equippedwithalow
draft adjustment port located on the control face just to the
right of the igniter light. Figure 5.4. This voltage adjustment
is provided to allow the unit to be adjusted for the household
voltage where the unit is going to be in permanent operation.
NOTE: The line voltage varies from area to area and often
home to home.
The low draft voltage should be adjusted to achieve the most
ecient burn on low burn or “maintenance”. This voltage
adjustment allows the installer to change the low voltage set
pointapproximately10volts.Thisadjustmentshouldbedone
by the installer during set up because a draft meter reading
is required to insure proper set up.
If the unit is not adjusted properly, it does not cause a safety
concern.Iftheunitisadjustedtoohigh,onlyeciencyislost.
If the unit is adjusted too low, the low draft pressure switch
will not allow the feed motor or the igniter to operate.
A simple draft test should be performed after completing the
