Assembly and Installation
Unpacking
The P1A is bolted (1 x 1 hex head bolts) to the skid to
prevent movement during shipping.
To free the stove from the skid you must remove the hold-
down bolts in the rear of the pedestal base.
R emoving rear cover panels
The rear cover panels are secured to the stove with three
bolts each. Two of the bolts need only be loosened, not
removed, to remove the panels. It is recommended that the
rear covers are installed after the unit is in place and the vent
pipe is installed, to prevent contact with hot or moving parts.
F irebrick
Install the three rebricks vertically on the angle bracket
above the burnpot.
F lame G uide
Install the cast iron ame guide on top of the burn pot. ake
sure that the ame guide is fully seated on the vertical sides
of the burn pot and that the back of the guide rests against
the body of the stove.
INSTALL EHAUST ENT AT CLEARANCES SPECIIE
BY THE ANUACTURER. ost pellet vent pipe requires a
minimum of  of clearance to combustible materials although
some can be installed at 1 clearance.
ollow these instructions along with all local codes regarding
installation of this appliance.
o NOT use makeshift compromises when installing this
appliance, serious consequences may result.
With any hearth appliance, installation of smoke detectors
is recommended on every level of the home.
Possible causes of smoke detector activation:
Paint curing process - Open a window near the appliance
for the rst few hours of burning.
Exhaust being drawn back inside the dwelling - Outside air
connection to the appliance is necessary.
ent leakage - All interior seams and oints should be sealed
with silicone where appliacable. ollow vent manufacturers
instructions for proper sealing.
The room sensor is a small temperature sensor on the end
of a 0 wire. This sensor is installed much like a standard
wall thermostat. There is a remote room sensor port on the
rear of the unit for easy external connection. Use standard
18-2 thermostat wire to extend the distance to the desired
location (50 maximum). The room sensor should be installed
in the location where you want to control the temperature.
NOTE: istances of more than 25 feet from the unit or in
another room are not recommended. The room sensor is
essential for the P1As excellent efciency.
NOTE: It is recommended that the room sensor be
installed, even if only installed on the rear of the unit as a
return air sensor.

A combustion blower is used to extract the combustion
gases from the rebox. This causes a negative pressure in
the rebox and a positive pressure in the venting system as
shown in ig. 7. The longer the vent pipe and more elbows
used in the system, the greater the ow resistance. Because
of these facts we recommend using as few elbows as possible
and 15 feet or less of vent pipe. The maximum horizontal
run should not exceed 8. If more than 15 feet of pipe is
needed, the interior diameter should be increased from  to
 because a larger pipe causes less ow resistance. Be sure
to use approved pellet vent pipe wall and ceiling pass-

F ig. 7
V ent Pipe
Pellet venting pipe (known as PL 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 1 to  inches. 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. or this reason and the fact that the unit operates
with a positive vent pressure we specify that the j oints
also be sealed with high temp (R TV ) silicone. Aluminum
tape can also be used for any oint that is 1ft. or more from
the outlet of the stove.
Avoiding Smoke and Odors
Negative Pressure, Shut-down, and Power F ailure:
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. ents 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 strongly recommends
attaching outside air in all installations, especially lower

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:
• aintain specied clearances to windows, doors, and air inlets, including air conditioners.
• ents should not be placed below ventilated softs. Run the vent above the roof.
• Avoid venting into alcove locations.
• ents should not terminate under overhangs, decks or onto covered porches.
• aintain 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 ex tend to, smoke damage caused
by reverse drafting of pellet appliances under shut-down or power failure conditions.
Per national building codes, consideration must be given to
combustion air supply to all combustion appliances. ailure
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
HAC professional to determine the ventilation demands for
your house.
To install outside air use 2 8 I.. non-combustible ex
pipe. There is a break-away hole on the rear panel of the
stove which must be removed to connect the ex pipe. The
maximum length run of this pipe is 15 feet. If a longer run
is needed the size must be increased to . Inlet cover part
number 1-10-0852 should be used to keep birds, rodents,
etc.out of the pipe unless the Harman wall passthrough is
being used.
Direct V ent W all Passthrough
The Harman irect ent Wall Passthrough (Part # 1-00-
77077) makes installing your Harman Pellet Stove with
outside air easier. It combines the needed wall protection
for the venting, with a source of intake air for combustion. It
is made to t walls from  12 to 10 18 thick with a single
square opening in the wall of -12 inches.
NOTICE: In Canada, ULC-S27 requires that all outdoor-
aired space heaters be secured to the structure.

# 2 Preferred method
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 three inches from a combustible
wall. This vertical section will provide natural draft in the event
of a power failure.
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.
Note: Do not place joints within wall pass-throughs.
# 1 Preferred method
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.
Note: Do not place j oints within wall pass-throughs.

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
the chimney. In most cases the inside diameter of this liner
should be . Either exible or rigid liner may be used for
this purpose. Refer to ethod   7.

AUTOMATIC IG NITION/ OPER ATION
The P1A is a fully automatic stove that features two
operating modes Stove Temperature Mode and Room
Temperature Mode. In Stove Temperature ode, you select
a burn rate and the stove will remain at the same burn rate
regardless of the room temperature.
In the Room Temperature ode the stove constantly monitors
the temperature in the room and adusts the size of the re
and the heat output of the stove so that the room is kept at
a constant temperature. Room mode, in the AUTO position,
has the added advantage of turning the stove off if no heat
is required and turning the stove on again when the room
temperature drops below your desired room temperature.
R oom Temperature Mode
ost consumers use the stove in the Room Temperature
ode because it is the easiest and most efcient method
of keeping the room at a given temperature. In the Room
Temperature ode, the Room Sensing Probe constantly
monitors room temperature. As the weather changes outside
and your home needs varying amounts of heat to be at a
desired temperature, the stove will automatically increase re
size and heat output so that a constant even temperature is
maintained. If the weather warms up and no heat is required,
the stove will gradually shut down. When the house cools
down, the stove will automatically bring the room temperature
to the precise temperature you desire.
In the Room Temperature ode you can select either Auto
or Manual modes for the igniter, using the igniter toggle
switch. When the toggle switch is in the Auto position, the
igniter, located inside the burn pot, is ready to automatically
light the re when required. When the toggle switch set to the
anual position the stove can be lit manually with either a gel
or a wax type re starter. (see lighting instructions on page
1.) With the igniter toggle switch set in the anual position
the stove will automatically adust heat output, but the stove
will not automatically shut down if no heat is required. Instead
it will go to its lowest setting and remain there. The anual
position on the igniter toggle switch lets you light the stove
manually, should the igniter fail for any reason. Secondly if
you are using the Harman battery back up system, the anual
setting will prevent the stove from turning off and on during
a power failure, which would drain the back up battery, and
possibly cause damage to the back-up or the stove.
In the Room Temperature ode, the distribution blower speed
can be increased or decreased by adusting the Room Temp
OffStove Temp dial between L and H. As output of the stove
increases, the speed of the blower will increase automatically
to insure that more heat is transferred out into the room. The
distribution blower will shut off as the room reaches the set
temperature, this will prevent overheating of the room.
R oom Temperature Mode: This setting, see above, will produce
a room temperature of 70 degrees with the distribution blower at
medium speed.

Shut Down Procedure
The best way to shut down the stove is to simply let it
run out of pellets. The stove will shut down automatically.
Alternatively, you can turn the ode Selector to off. This
will cause the re to gradually die down and go out. The re
will not go out immediately and may take more than an hour
to fully shut down.
If the stove is left to run out of fuel, you may get a  blink
status light. If this happens simply reset the control board by
turning the mode selector to O and back ON.
Stove Temperature Mode
In the Stove Temperature ode and with the igniter toggle
switch in the Auto position, the stove will light automatically
and can be adusted to the desired setting using the same
temperature control dial as is used in the Room Temperature
ode. The heat output and fuel consumption will remain
constant regardless of room temperature. The settings from
1 to 7 on the inner ring of the temperature dial provide for
relative heat output settings with 1 being low and 7 being
the maximum.
In Stove Temperature ode, the stove will not automatically
shut off unless the stove runs out of fuel or is turned off.
Never pull the plug to shut down the stove. This will stop the
combustion blower and smoke will escape through window
and door gaskets.
When the igniter toggle switch is set to manual in this mode,
the distribution blower will not turn on with a temperature dial
setting from 1 to 5. The advantage of this mode is to allow
the operator to have a large viewing re without blowing extra
heat into the room.
uring manual operation, with the temperature dial set
at # or less, the distribution fan will not operate. A #
on the temperature dial and a #5 on the feed aduster is
approximately 80 output. It is not necessary to operate the
distribution blower below this point. Therefore, the control
allows a higher burn rate ( a larger viewing re) without an
excess of hot air blowing into the room.
An example of when to use the anual Stove Temperature
ode is if you want to watch a large re and the room is
already up to temperature. The Stove Temperature ode
allows you to have a larger re and a lower sound level,
without the distribution blower.
NOTE: uring the use of this mode, if you keep increasing
the temperature dial setting to increase the re size, the
distribution blower will automatically come on when the ESP
Temperature reaches 50o , or 81 output.
F eed Adj uster K nob
or most premium grade pellet fuels the eed Aduster nob
should be set at . If higher ash fuels are used the setting
should be increased to 5 or . Also higher settings are
required if you would like to get the maximum heat output from
the stove. At the maximum burn rate (with the temperature
dial on 70 and the feed aduster at ) there should be 1 or
more of ash on the front of the burn pot. If there is less than
1 of ash, turn the feed aduster knob down to a lower setting.

Helpful Hints
1. Fines are small pieces of broken pellets (sawdust). Fines do not
ow easily and often build up on the hopper funnel bottom angles.
You can push these nes into the feeder opening and then ll the
hopper with pellets. As the system works, they will be burned. Or
you can clean them out before lling the hopper.
2. The "TEST" cycle will operate the feeder motor for exactly one
minute. Turning to "TEST" again and again may charge too much
fuel into the burn pot causing excessive smoke on start-up.
3. The rebox low pressure switch will not allow the auger motor
or the igniter element to operate if the view door or the ash pan
door are open.
4. Adjust Feed Rate. If this is your rst re or you are trying different
pellets, set the feed adjuster to #4, Fig. 17. This is a conservative
number and will probably need to be increased. After you know a
feed rate setting that works well, use that setting. Remember, if your
feed rate is too high you may waste fuel.
5. This is usually a weekly maintenance procedure. Cleaning the
burn pot with the scraper with a small amount of new fuel in the
bottom is not a problem. First, scrape the ashes off the front of the
burn pot into the ash pan. Then, scrape the top surface of the burn
pot downward into the base of the burn pot. When the stove is
ignited these scrapings will be pushed out by the feeder and burned.
6. The ash pan can hold the ashes from approximately 1 ton of
premium fuel. This means the ashes will only need to be emptied
a few times each year.
7. Setting the feed adjuster # for maximum burn: With the unit
burning in "AUTO", turn to "Stove Mode" and put the fan on "H".
Set the Temperature Dial to #7. Allow the unit to burn for about 30
minutes and check ash on front of burn pot. Fig. 18. If the ash line
is larger than 1", turn the feed adjuster from #4 to #5. Allow another
30 minutes of burn time and check again. If , at #6 setting, a 1" or
less ash bed is not obtainable, it is not a problem. The 1" ash bed
is only a maximum burn rate and at most normal settings the ash
bed will be larger.

6. The ash pan can hold the ashes from approximately 1 ton of
premium fuel. This means the ashes will only need to be emptied
a few times each year.
7. Setting the feed adjuster # for maximum burn: With the unit
burning in "AUTO", turn to "Stove Mode" and put the fan on "H".
Set the Temperature Dial to #7. Allow the unit to burn for about 30
minutes and check ash on front of burn pot. Fig. 21. If the ash line
is larger than 1", turn the feed adjuster from #3 to #4. Allow another
30 minutes of burn time and check again. If , at #6 setting, a 1" or
less ash bed is not obtainable, it is not a problem. The 1" ash bed
is only a maximum burn rate and at most normal settings the ash
bed will be larger.

Low Draft V oltage Adj ustment
These units are pre-tested at the factory with exactly 120 AC,
0 Hz. They are checked and adusted for rebox tightness,
gasket leakage, motor operation and igniter operation. The
P1A is then factory set at a mid-point adustment and in most
cases will not need any adustments. NOTE: The factory low
draft setting may not be correct for the unit' s permanent
installation conditions.
The control board on the P1A is equipped with a low draft
adustment port. Located on the control face ust to the right
of the igniter light. This voltage adustment is provided to allow
the unit to be adusted 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 adusted to achieve the most
efcient burn on low burn or maintenance. This voltage
adustment allows the installer to change the low voltage
set point approximately 10 volts. This adustment should
be done by the installer during set up because a draft meter
reading is req uired to insure proper set up.
If the unit is not adusted properly, it does not cause a safety
concern. If the unit is adusted too high, only efciency is lost.
If the unit is adusted too low, the low draft pressure switch
will not allow the feed motor or the igniter to operate.

Low Draft V oltage Adj ustment
A simple draft test should be performed after completing the
ue pipe installation. To record the results for future reference:
1. Plug unit into a 120 AC, 0 Hz outlet.
2. Close the hopper lid, front view door, and the ash pan.
Neither pellets or a re are required for this test.
. With the mode selector in the O position, turn the feed
aduster to TEST.
. Record the high draftin W.C. (Normal is -.50 to -.0)
The control will be on the High raft for a total of 1 minute.
5. After the minute, the combustion motor will go down to
low draft and the distribution blower will go on high. Allow
approximately 15 seconds to pass for the combustion
motor to slow before checking the low draft.
. If the low draft is between -.5 and -.5, record the reading
 in W.C. If the reading is higher, slowly turn the
set screw counter-clockwise until the draft lowers. If the
reading is lower, very slowly turn the set screw clockwise
until the draft increases.
NOTE: In some cases, the draft may not go as low as
-.3 5 to -.4 5 even with the set screw completely counter-
clockwise. Ideally, you should j ust set it as low as
possible.
