The Accentra Pellet Insert will give you more heat, better temperature control and a level of convenience you wont nd in
any other pellet burning insert. The Accentra Inserts many outstanding features make it the best value pellet insert on the
market today.
The Accentras versatile design lets you convert a heat wasting replace into an efcient heating source. The Accentra Insert
could also be a replace hearth for your home that doesnt require a chimney. A special zero clearance replace kit converts
the Accentra insert into a replace that can be placed in virtually any corner or against any wall of your home.
The Accentras on-board microprocessor constantly senses room temperature and automatically makes adustments in the
feed rate and air supply so you get ust the right amount of heat 2 hours a day. This remarkable technology lets you ll the
hopper, set the desired temperature and walk away. The Accentra insert lights automatically, brings the room up to the exact
temperature and will turn off if no heat is required. No other pellet insert offers such accurate and trouble free temperature
control. The control technology gives you the widest heat output range of any insert on the market making it an ideal choice
to take the chill off in the spring and fall and to heat your home during the coldest months of the winter.
As with all Harman pellet stoves, maintenance is minimal and cleaning is easy. The Accentra Insert lets you burn close to a
ton of pellets before ash removal is needed. And what is even better, the Harman Insert Track System lets you slide the insert
out of the replace so that it can be cleaned or serviced without having to disconnect the venting system. This innovative
design is only available on Harman pellet inserts and lets you easily reach key components for cleaning.
Note: This appliance is also approved for installation into a
shop.

. lip the Igniter Switch up into the AUTO position.
7. Turn the Temperature ial to the desired room temperature.
8. Turn ode Selector to Room Temperature or Stove

. ill hopper with pellets and remove ashes as required.
eep the hopper lid and firebox doors closed while in
operation. aintain door seals in good condition. ailure to
do so will affect operation of the appliance and may permit
escape of smoke or gases into the living space.
Automatic Start Up
1. Fines are small pieces of broken pellets (sawdust). Fines do
not ow easily and often build up on the hopper funnel bottom
angles. These nes can be pushed into the feeder opening and
then ll the hopper with pellets. As the system works, they will
be burned.
2. The "TEST" cycle will operate the feed motor for exactly one
minute. Turning to "TEST" again and again may load 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 is open.
4. Adjust Feed Rate. If this is your rst re or you are trying different
pellets, set the feed adjuster to #4, Fig. 1. 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 holed surface
downward into the burn pot. When the stove feeds, these
scrapings will be pushed out by the feeder.
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 a 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. 2.
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 at maximum burn rate and
during normal operation, the ash bed will be larger.

The Accentra Insert is more than ust automatic ignition, it is
also automatic temperature control. The automatic system will
allow the re size to be adusted to match the heating needs
and even put the re out if necessary. If heat is needed after
the re is out, the Accentra Insert will automatically re-ignite
and adust the re size to match the heating need. The totally
automatic room sensor mode is recommended because of
its efciency. The unit can be switched between AUTO and
ANUAL at any time during operation.
Igniter switch to " AUTO"
R oom Temperature Mode
In Room Temp ode heat output is controlled automatically
by the Room Sensing Probe. When the Room Sensing Probe
calls for heat, the stove will increase output. When the Room
Sensing Probe is getting close to the set temperature, the
stove will begin to level off output and keep the re burning
at ust the right temperature to maintain that setting.
High output is determined by the feed rate setting. This
setting, generally on #, can be increased if higher burn rates
are necessary (ig. 1). The units maximum burn rate should
not create less than 1 of ash on the burn pot front edge(See
ig. 2). Overfeeding is not a safety concern, but fuel may be
wasted if unburned pellets fall into the ash pan.
In Room Temp ode a constant fuel consumption rate is
sacriced for exact room temperature. Therefore, as it gets
colder more pellets will be burned automatically.
The distribution blower speed will vary according to the
position of the mode selector pointer, and re size.
Igniter switch to " AUTO"
Ste emperature e
This allows for automatic ignition upon start-up only. The unit
can then be set at any desired setting. The heat output and
fuel consumption will remain constant regardless of room
temperature (See ig ). The units maximum feed rate
should not create less than 1 of ash on the burn pot front
edge. See ig 2.
The units low burn or maintenance setting is as low as it will
go. It will not go out unless it runs out of fuel or is turned off.
Shut-Down Procedure
To kill the re or stop burning the stove, turn the ode
Selector to O. This will cause the re to diminish and
burn out. When the re burns out and the stove cools down
everything will stop.
If you pull the plug to shut down the stove, all motors will stop.
This may cause incomplete combustion and smoke in the
rebox. If the load door is opened, the smoke may escape.
The best way to shut down the stove is simply let it run out
of pellets, then the stove will shut down automatically.

1. Fines are small pieces of broken pellets (sawdust). Fines do
not ow easily and often build up on the hopper funnel bottom
angles. These nes can be pushed into the feeder opening and
then ll the hopper with pellets. As the system works, they will
be burned.
2. The "TEST" cycle will operate the feeder motor for exactly one
minute. Turning to "TEST" again and again may load 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 hopper
lid 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. 5. 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 holed surface
downward into the burn pot. When the stove is ignited these
scrapings will be pushed out by the feeder.
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 a 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. 9. 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 at maximum burn rate and
during normal operation, the ash bed will be larger.

The Accentra Insert is capable of manual operation. This also allows the operator to manually
control operation during an emergency (i.e. igniter failure, when using a 502H battery backup,
or when using certain generators.)
The unit can be switched between AUTO and ANUAL at any time during operation.
NOTE: When starting the unit in the " AUTO" mode
and switching to " MANUAL" , you may switch at any

The difference between AUTO Room Temperature ode
and anual Room Temperature ode is that the re will not
go out as the room temperature goes above the control board
setting. The unit can only go to low burn and will remain there
until it runs out of fuel or until more heat is needed and the
feed rate increases. eed rate adustments and dial settings
are the same as AUTO settings.

The advantage of this mode is to allow the operator to have
a large viewing re without blowing extra heat into the room.
uring operation, with the temperature dial set at # or less,
the distribution fan will not operate. A # on the temperature
dial and a # on the feed aduster is approximately 80
output. It is not necessary to operate the distribution blower
below this point. Therefore, there can be a higher feed 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.

IMPOR TANT: The mounting framesurround assembly and
ue piping is the most critical part of the installation and must
be done correctly and installed securely.
1. Choose the chimney conguration that is best suited for
the installation. See venting section. Page 21
Note: If 100 outside air is desired or required, the outside
air option will need to be installed on the stoves body. (See
instructions included with outside air kit (part #1-00-7080.)
See Page 22.
2 . ake sure the unit will t into the replace opening. When
installing in smaller replaces, test t the mounting frame
into the rebox. Note: The unit overhangs to the rear. See
ig. 17
3 . Installing the 3 piece cast surround: Install the left and
right cast sides to the mounting frame using the 1-20 x
8 bolts supplied. Install () 1-20 x  set screws into
the top wing. Then install the top wing onto the frame using
the () 1-20 nuts. The left and right side should be done
before the center section is installed. ake sure the bolts
are loose. o not remove the side panel hinges. The left
and right side wings should be standing up aligned with
the side of the mounting frame and slid inward towards
the center. Note: The wings mount on the rear side below
the notch and on the front side above the notch. See ig.
1  18. Slide the cast ash lip onto the frame and check
to make sure it can go against the roped frame rails and
ts into the pockets on the left and right cast sides. See
ig. 1.
Install the center section.

5 . The power cord can be installed exiting the left (standard)
or right side of the surround. If a right side cord is desired,
follow the instructions below.
The cord is located on the left side, standard from Harman.
(See g 21.)
To route the cord to the right side:
Cut the wire-ties looping the cord to the left
Re-route the cord along the top of the steel angle and down
the right side.
Re-tie (not supplied by Harman) the wire through the notches
provided in the mounting frame. Then down the right side rail.
o not remove or move the cord retainer, it is made to reach
both the right and left sides.
Nothing can ex tend

CUT.
With the three wing pieces completed, the cord retainer must
be bolted to the bottom rear of the wing. Either left exit (shown
in g. 22) or right exit.
At the bottom rear edge of the right and left wing there is a
small radius indent for the cord to exit between the wing and
the replace face.
. You must now decide whether to install the room sensor
as a wall sensor or as a return air sensor. Harman highly
recommends that the room sensor be installed. If you are
installing the room sensor as a wall sensor, the long black
2 wire cable must be wire-tied to the power cord. This wire
is long enough to reach the end of the power cord so the
installer can reach past the hearth to the location where
the extension wire (182 thermostat wire, not supplied by
Harman) can be spliced to go to the wall location chosen
for the room sensor.

extension is 8 wide by  high.
Custom sized wing extensions can be purchased from your
dealer, for any replace openings larger than the standard
wing extension area.
These optional wing extensions will have a 12 inch return
bend as shown in g. 20. Custom oversized wing extensions
with a radius top can be ordered with a radius of your
choosing. These radius wing extensions WILL NOT have a

7 . If the room sensor is used as a return air sensor
rather than a room thermostatsensor, the black cable
will not be used. The room sensor itself (gray or black
cable with black and red wires) will be connected to
the blue twisted wires from the control board.
Note: The stove body must be able to slide out of the
shell to the limit of the power cord wires for cleaning and
service. Therefore, if the room sensor is connected as
a return air sensor, the wire should be connected long
enough to allow this, but not too long that it would get
tangled or pinched anywhere.
Notice: The malefemale connections between the
mounting shell and the stove body should always be
maintained. Wirenut or taped splices should never be
used.
Insert the sensor end of the wire from the rear of the
mounting frame through the hole as shown in g. 2 .
Wire-tie the sensor end so that the sensing tip is in the
middle of the front return air opening. See ig. 25.
Wire-tie the sensor wire to the inside of the mounting
frame up to the cord grounding location. ollow the
power wiring to where you make the malefemale
terminal connection to the twisted blue wires.
There are (2) crimp-on connectors in the hardware pack
that must be installed on the internal ends of the room
sensor wires.
8 . Install the () 8-1 x 1 leveling bolts into the
threaded holes in the bottom pan of the mounting
shell. The front two leveling bolts may not be
necessary, but the back two will need to be used
to level the wing so that it is ush with the replace

10. Test t the cast ash lip (See g. 25) on the shell frame
mounting rails. The ash lip should slide on these side
rails without lifting upward off of the rails as the ash lip is
slid inward. A small clearance of about 11 is an ideal
space between the legs of the ash lip and the hearth.
This cast ash lip is a decorative part that does not and

• Connecting the room sensor to the blue twisted wires from
the control board:
• (2) 1 inch male terminals are provided for the ends of
the room sensor wires.
• They will mate with the female terminals on the blue
twisted wires.
• These connections are not polarity specic.
• Inspect the silicone sponge hopper to top seal gasket.
• Look for tears or areas where the gasket may not seal
properly to the bottom of the cast top. This only needs to
be done when the top is removed. This is NOT necessary
if the cast top is not removed. (Not part of any monthly,
semi-annual or annual maintenance.)
ig. 
Every time the unit is pulled out of the mounting frame, the
orange high temperature docking gasket should be inspected.
Check for tears or signs that the gasket is not sealing properly.
1. Inspect the silicone sponge gasket on the top edge of
the hopper.
• If it is okay, put the cast tophopper lid assembly (see ig.
5) into place over the hopper.
• ake sure the hopper lid is open to install the top, then
close it to keep from getting pinched in case the lid falls
unexpectedly.
• Insert the () 1-20 x 12 ange head bolts into the
mounting hole but do not tighten them. See page , g.

Installation
• The stove body must be pulled out of the mounting frame
several inches to install the cast side panels.
• Slide the cast side panel down over the hinge pins.
• Slide the stove body in and latch into place.
Note: The cast side panels must be left in the open position
to allow access to the latches.
• Slide the ash lip into place. (This would be inward until the
rear of the cast iron touches the mounting frame front.)
• Close the cast side panels.
• Check the gap alignment and the top and bottom gap
spacing.
• The top and bottom spacing can be adusted by loosening
the  bolts and sliding the hinge up or down until the
spacing suits.
• With the front door closed and latched, check the vertical
space alignment. The only method of changing or
adusting this gap is by bending (slightly) the hinge angle.
See g. .
• ue to the use of all cast iron parts, some small amounts of
misalignment are expected. Since some parts are angled
and some have rounded edges, this misalignment is very
seldom noticeable.
• It is very important that the cast side panels open and
close freely for control board access.
22. Slide the stove body into the mounting frame.
• Note: The two spring latches on the bottom
right and left side of the body must be in the proper
position to enter the latch holes. (See g. 7).
• Latch the (2) spring latches into place.
23. Shift the cast tophopper lid assembly inward as far as
possible to achieve a parallel t with the surround sides.
See ig. . Tighten the cast tophopper lid assembly
bolts with a 8 socket. See page , ig. 12.
24. Install and adust the side panel magnets.
• In the hardware pack are (2) magnets, (2) spacers and
(2) 10-2 x 1 1 bolts and nuts.
• Bolt the magnets through the holes provided in the cast
ash lip.
Important: The spacer must be on top of the hole, the magnet
on top of the spacer, with the bolt going, down, through the
hole, with the nut at the bottom, under the ash lip. See g. 8.
25. Check the t of the cast ash lip to make sure that it can
be slid in and out easily. The cast ash lip can remain in
place at this time. Note: The cast side panel hinges can
be moved upward if necessary to gain clearance for the
cast ash lip.

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
stove is then factory set at a high adustment. NOTE: Low

installation conditions.
The control board on the Accentra Insert is equipped with a
low draft adustment port. Located on the control face ust
to the right of the igniter light. See igure . 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 15 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 feeder motor or the igniter to operate.
After the installation is completed, but before the rst re is lit, check and record the
high and low draft readings.
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 and front view door. 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 -.5 to
-.55) The control will be on the High raft for a total of 1
minute.
5. After 1 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 .0 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.

When installing the Accentra in a mobile home several
requirements must be followed:
1. The unit must be bolted to the oor. This can be done
with 1 lag screws through the 5 holes in the base
plate shown in ig. 2.
2. The unit must also be connected to outside air. See
page 22. All mobile home installations require the use
of outside air, this will increase the heating efciency of
the unit and keep it from suffering any effects associated
with room air starvation such as poor combustion and or
erratic operation. Periodically check the air inlet for any
obstructions such as snow or ice build up.
itchen exhaust fans, clothes dryers and other similar
devices may cause improper operation of the pellet
stove, if, while in use, it keeps the room in a negative
pressure, thus allowing pipe oints, not completely sealed,
to leak exhaust into the room. Be sure to allow adequate
ventilation while using such appliances
. loor protection and clearances must be followed. loor
protection and clearances to combustibles must be
followed as per installation instructions for the stove.
Clearances may only be reduced by means approved by
the regulatory authority.
. Unit must be grounded to the metal frame of the mobile
home.
5. Smoke alarms and smoke detectors are recommended
to be used with wood and biomass fueled stoves. When
opening the rebox door some exhaust may escape into
the room and set off the alarm. If this should happen
ventilate the room to remove the smoke and reset the
alarm, if the alarm would go off when no one was working
with the stove ventilate the room and have your home
checked to nd the source of the leak.
