A. Design, Installation & Location Considerations
1. Appliance Location
Considerationmustbegiventosafety,convenience,trafc
ow,andthefactthattheappliancewillneedtobevented
to the outside. This appliance may only be installed into
an existing masonry or manufactured wood-burning
replace or using the optional zero-clearance cabinet
to build into a newly constructed chase. It is a good idea
toplanyourinstallationonpaper.Useexactmeasurements
forclearancesandoorprotection,beforeactuallybeginning
the installation.
Maintain specied vent clearance to combustible
requirements listed by the vent manufacturers instructions
and all appliance clearances as listed in this manual.
Check with your local building code agency before you
begin your installation. Local codes may supersede the
testlaboratoriesspecications.Alwaysobtainanyrequired
permit(s) so that insurance protection benets cannot be
unexpectedlycancelled.Ifanyassistanceisrequiredduring
installation, please contact your dealer.
Werecommendthataqualiedbuildinginspectorandyour
insurance company representative review your plans before
and after the installation.
2. Room Sensor Location
The room sensor's location will have some effect on the
appliance'soperation.Whenthesensorislocatedcloseto
the appliance, it may require a higher setting to keep the
rest of the house comfortable. If the sensor is located in
an adjacent room, or farther away from the stove, you will
notice higher temperatures near the appliance.
B.FireSafety
Maintain the designated clearances to combustibles.
Insulation must not touch the chimney. You must maintain the
designated air space around the chimney. This space around
a chimney is necessary to allow natural heat removal from
the area. Insulation in this space will cause a heat buildup,
which may ignite wood framing. NOTE: Clearances may
only be reduced by means approved by the regulatory
authority having jurisdiction.
To provide reasonable re safety, the following should be
given serious consideration:
1. Install at least one smoke detector on each oor of
your home. Detectors should be located away from
the heating appliance and close to sleeping areas.
Follow the smoke detector manufacturer's placement
and installation instructions, and be sure to maintain
regularly.
2. A conveniently located Class A re extinguisher to
contendwithsmallresresultingfromburningembers.
3. A practiced evacuation plan, consisting of at least two
escape routes.
4. Aplantodealwithahopperreasfollows:
Intheeventofahopperre:
a.Turnapplianceto"OFF".
b. Be sure hopper lid is closed and latched.
c. Notify Fire Department.
d.DoNOTpourwaterinthehopper.
e. Never pull the plug or otherwise disconnect the
powersupplytokillare.
• Do NOT connect this unit to a chimney flue
servicing another appliance.
• DoNOTconnecttoanyforcedairdistributionduct
or system.
CAUTION

F. Factory Built Fireplace Installation
When installing the P35i Insert into a factory built wood
burning fireplace, several things need to be taken into
consideration.
The size of the replace opening. Will the unit t into the
opening? Some of the factory built replaces have metal
smokeshieldsinsidethetopthatcanberemovedtogain
height. Keep in mind that anything removed from the factory
builtreplacemustbeattachedtothereplacewithametal
wire. Floor protection guidelines, as listed previously, must
also be followed.
Themanufacturedreplacemaynotbealteredbeyondthe
exceptions listed below. Never remove masonry bricks or
mortarfromanexistingreplace.
Thefollowingmodicationsarepermissible:
• Removalofthedamperorlockinopenposition
• Removalofsmokeshelforbafe
• Removal of andirons or ember catchers
• Removal of log grate
• Removal of view screen or curtain
• Removal of doors
• Externaltrimpieces,thatdonotaffecttheoperationof
the replace, may be removed providing they can be
stored on or within the replace for reassembly if the
insert is removed.
• Ifthehearthextensionislowerthanthereplaceopening,
theportionoftheinsertextendingontothehearthmust
be supported.
• Final approval of this type of installation is contingent
upon the authority having jurisdiction.
• Kit #1-00-674205 must be used when using this
installation method.
Note: If the Harman®P35iInsertisinstalledintoafactorybuiltwoodburningreplace,thislabel(Harman®part#3-90-00675)
MUST beattachedtothealteredreplace.
Thefactory builtchimney mustbelisted perUL127(US)
and meet type HT requirements of UL 103 (US). Factory
BuiltreplacechimneystestedtoUL127-98maybe,atthe
replacemanufacturersoption,testedtothesamecriteria
as UL 103HT requirements. If the chimney is not listed as

NOTE: The restriction of not venting more than one appliance
tothesameueappliestotheU.S. specically.Whileitisnot
recommended that you use the same chimney for more than
one appliance, in Canadacertainexceptionsmaybemade.
Besuretocontactyourbuildingcodeinspectionofcialto

B. 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:
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.
The outside air kit consists of a ue stub pipe, berglass
gasket,siliconegasket,intakeboxandasectionofexpipe.
Anadjustablechimneyintakeextension,part#1-00-674104
is available to be used on masonry chimneys only.
Toinstalloutsideair,usekitpartnumber1-00-774280.Follow
theinstallationinstructionsprovidedwiththekit.
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" 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.
Do not connect this unit to any air distribution duct

C. Routing the Power Cord
When choosing an electrical supply outlet, be sure the
polarity is correct, and that the supplied voltage is within
the range of 117 to 123 Volts. Surge protection is also
recommended to protect the control board software in the
eventofasurgeorspike.
Oncetheoutletlocationisdecided,you'llneedtoinstalland
route the power cord.
At the bottom of each of the side surround panels is a
knockout for the cord retainer. Remove the appropriate
knockoutandfeedtheloosewireendofthecordintothe
hole. If your cord needs to exit
from the right side, route the cord
up the side and over the top of the
mounting frame and back down
the left side. Use the two hooks
on the top corners of the mounting
frame to secure the cord. Attach a
star washer, the ground wire ring
terminal, a second star washer,
the ring terminal from the ground
wire jumper to the bottom stud of
the left surround panel. Using a
pliers, compress the cord clamp
and push it into the hole.
B. Installing the Surround
The surround consists of three panels, the top and two
sides. Follow these steps for installation:
1. Removetheinsertbodyfromthemountingframe;
2. Startyour levelingbolts into theoor oftheframe and
adjusttoslightlyraisetheheight.(seenextsection)This
will allow some clearance to assemble the surround.
3. Prepare the side panels by removing three nuts each.
The left side panel is the one with the control board
opening.Ifmountingthecontroldoor,thehingebracket
will attach using the control panel mounting screws.
4. Attach the side panels to the mounting frame by guiding
the threaded studs through the holes in the mounting
frame. Slip the power cord ground wire terminal over
the bottom stud on the left side. Install the nuts onto the
studs,ngertightenonly.
5. Installthetoppanel,makingsuretoclosethegapwith
the side panels rst. Tighten the nuts on the splice
bracketssecurely.
6. Set the mounting frame into position in the replace
opening. Be sure the surround panel is raised slightly so
that it is not supporting any of the weight of the mounting
frame.
7. Whenpleasedwiththealignment,tightenallofthenuts
securely.
8. Therearetwomoreholesinthesplicebracketstoalign
the outer sides of the surround panel joints. If desired,
