Introduction
Thank you for purchasing the Harman XXV Pellet Stove. The Harman XXV Pellet Stove is the culmination
of elegance, convenience, functionality and dependability
The XXV was thoughtfully designed to look captivating in every home. Intricately detailed oak leaves
express the magnitude of craftsmanship that goes into making this stove a masterpiece. These beautiful
castings are proudly made in the U.S.A.
Built to strict Harman standards, the XXV has the most advanced construction of any Harman Pellet Stove.
This 25th Anniversary Stove is based on Harman's patented pellet stove technology and goes a few steps
further. The glass hopper lid allows you to see the fuel level while the mirrored front glass transforms into
clearglasswiththeradianceofthere.
A new concept for the XXV is the ability to use the top vent option. Using this method, the XXV can easily
replace a wood stove by placing the top vent adapter over the rear vent.
We put all of our favorite features into the XXV, fusing the highest caliber pellet stove innovations with
the allure of cast iron.
This label is located on the back of the unit.
Please copy the Serial Number for future reference.

A combustion blower is used to extract the
combustiongasesfromtherebox.Thiscausesa
negativepressureinthereboxandapositivepres-
sure in the venting system as shown in Fig. 6. 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 48".
If more than 15 feet of pipe is needed, the interior
diameter should be increased from 3" to 4" because
alargerpipecauseslessowresistance.Be sure
to use approved pellet vent pipe wall and ceiling
pass-through ttings to go through combustible
walls and ceilings. The use of a starting collar is
notalwaysnecessary.Therstpieceofpipeshould
be fastened securely with at least 2 fasteners to the
uecollarofthestove.Ifastartingcollarisusedto
attach the venting system to the stove, the starting
collar must be sealed to the stove with high temp
silicone caulking.
Vent Pipe
Pellet venting pipe (Known as "L" or "PL" vent-
ing) is constructed of two layers with air space
between the layers. This air space is an insulator
which reduces the surface temperature and allows
a clearance to combustibles of 3 inches or less. 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 XXV operates with a positive vent pressure we
specify that the joints also be sealed with silicone.
Aluminum tape can also be used for any joint that is
1 ft. or more from the outlet of the stove.
When using the top vent option, 6 inch single
wall pipe must be connected with at least three (3)
screws. Also, the joints must be sealed with high
temperature silicone.
We cannot emphasize enough, the importance of
sealing every seam and joint in the venting system
which is inside the home. Even the smallest pin hole
can leak and when it does you will smell wood smoke
or a creosote smell in the room. If this occurs check
for leaks. Leaks are easiest to see during start-up.
Alternatively you can use a smoke pellet to leak test
theventingbeforelightingyourrstre.

IMPORTANT NOTICE
Pellet Vent Pipe or PL Vent Pipe Must Be Used

Outside Air
Here arefourbenetsof outside air:
1. Having air introduced from outside the living area
booststheoverallthermalefciency.
2. It eliminates draft problems that can occur in tight
homes.
3. It reduces the chance for smoke spillage in the
event of a power failure.
4. It allows your vent termination to be as close as
18" from windows or doors.
Outside air is optional except in mobile homes and
wherebuildingcodesrequire.Thebenetofoutside
air is mainly noticed in small, very tight, houses.
To install outside air use 2 3/8" I.D. non-
combustibleexpipe.Thereisabreak-awayhole
on the rear panel of the XXV stove which must be
removedbeforeconnectingtheexpipe.The pipe
should be run outside and terminate to the side or
belowtheventpipeoutletsotheueoutletismore
than 12" from the inlet cover. The maximum length
run of this pipe is 15 feet. If a longer run is needed
the size must be increased to 3". Inlet cover part
number 1-10-08542 should be used to keep birds,
rodents, etc.out of the pipe unless the Harman wall
passthrough is being used.
Direct Vent Wall Passthrough
The Harman Direct Vent Wall Passthrough (Part
# 1-00-677077) makes installing your Harman Pel-
let Stove with outside air a lot 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 4 1/2" to 10 1/8" thick with a single square
opening in the wall of 6-1/2 inches.

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 joints within

This method also provides excellent venting for
normal operation but requires the stove to be in-
stalled 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

If the stove is installed below grade be sure the
vent termination is at least 18" above grade. The
outlet must also be 1 foot from the house/building.
Note: Do not place joints within wall pass-
throughs.

#3 Installing into an existing
chimney
This method provides excellent venting for nor-
mal 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.
*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4".Eitherexibleorrigidlinermaybeusedfor
this purpose. Refer to Method 6.
Be sure to design the venting so that it can be
easily cleaned.

#5 Installing into an existing replace
chimney (US and Canada)
This method provides excellent venting for normal
operation. This method also provides natural draft in
the event of a power failure.
Some places in the US and Canada it is required
that the vent pipe extend all the way to the top of the
chimney. Per ULC S628.
In this method a cap should also be installed on
the chimney to keep out rain. Be sure to use ap-
provedpelletventpipettings.Sealpipejointswith
silicone or aluminum tape in addition to the sealing
system used by the manufacturer. Pipe size should
be increased to 4" using this method.

#7 Installing into an existing chimney
using 3" pellet vent in combination
with 6" or 8" single or double wall
stove pipe.
This method allows the installer to use 6" or 8"
single and double wall stove pipe ( sealed seam not
snap lock ) and
an existing masonry or class A chimney to vent the
stove.
The stove must use pellet vent and 90 degree
elbow to start at the stove connector and then use
the approved pipe adapter to connect to the size
of vent that continues into the chimney connector.
Support of the assembly must follow any pipe and
connector manufacturers recommendations.
Due to combustible fuel, vent pipe to hopper
clearances must meet guidelines stated by NFPA
or local codes.
#8 Installing through the ceiling
Through the ceiling vent, follow vent manufacturers
recommendations when using a wall or ceiling pass
through. Note: Do not place joints within wall
pass-throughs.

XXV Pellet Stove
These units are pre-tested at the factory with exactly
120 Volts A.C., 60 Hz. They are checked and adjusted
forreboxtightness,gasketleakage,motoroperation
and igniter operation. The XXV 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.
The control board on the XXV is equipped with a low
draft adjustment port. Located on the control face just
to the left of the igniter light. 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efcientburnonlowburnor"maintenance".
This voltage adjustment allows the installer to change
the low voltage set point approximately 10 volts. This
adjustment should be done 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. If the unit is adjusted too high, only

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: The test mode alternates from high to low
draft every 60 seconds. If more time is needed
for draft adjustment, wait until the next low draft

AUTOMATIC IGNITION/OPERATION
Room Temperature Mode: This setting, see above,
will produce a room temperature of 70 degrees with the
distribution blower at medium speed.
The XXV is a fully automatic stove that features two
operating modes; Stove Temperature Mode and Room
Temperature Mode. In Stove Temperature Mode, you
select a burn rate and the stove will remain at the same
burn rate regardless of the room temperature.
In the Room Temperature Mode the stove constantly
monitors the temperature in the room and adjusts the size
ofthereandtheheatoutputofthestovesothattheroom
is kept at a constant temperature. Room Temperature
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 set point.
Room Temperature Mode
Most consumers use the stove in the Room Temperature
Modebecauseitistheeasiestandmostefcientmethod
of keeping the room at a given temperature. In the Room
Temperature Mode, 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
adjustsizeandheatoutputofthere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 your desired setting
In the Room Temperature Mode 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 is set to the Manual position, the stove can
belitmanuallywitheitheragelorawaxtyperestarter.
(see lighting instructions on page 18.) With the igniter
toggle switch set in the Manual position the stove will
automatically adjust the 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 Manual
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
Manual setting will prevent the stove from turning off and on
during a power failure, which will drain the back up battery,
and possibly cause damage to the back-up or the stove.
In the Room Temperature Mode, the distribution blower
speed can be increased or decreased by adjusting 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.
Room Temperature Mode
Fig. 20
17
XXV Pellet Stove
Stove Temperature Mode
In the Stove Temperature Mode and with the igniter
toggle switch in the Auto position, the stove will light
automatically and can be adjusted to the desired setting
using the same temperature control dial as is used in
the Room Temperature Mode. 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 dial provide for relative heat output settings with
1 being low and 7 being the maximum.
In Stove Temperature Mode, the stove will not
automatically shut off unless the stove runs out of fuel
or is turned off.
Never disconnect the power cord to shut down the
stove. This will stop the combustion blower and smoke
will escape through window and door gaskets.
Feed Adjuster Knob
For most premium grade pellet fuels, the feed
adjuster should be set at #4. If high-ash fuel is used,
the setting may need to be adjusted to #5 or 6. Higher
settings are also needed if you want to achieve the
maximum capacity of the stove. Just be sure that when
burning at maximum, Stove temperature mode with the
feed adjuster on #6 and the temperature knob on "7"
or "90°", the pellets are not falling off of the front of the
burn pot before they have a chance to burn completely.
You should try to keep about one inch of ash in front of
the burning pellets.
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 Mode 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
6 blink status light. If this happens simply reset the
control board by turning the mode selector to OFF and
back ON.
This setting, see above, will produce continuous maximum
heat output with the distribution blower at full speed.
Stove Temperature Mode
This setting, see above, will produce continuous medium
heat output with the distribution blower at low speed.

AUTOMATIC START UP
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 purge 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. 22. 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 on 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 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. 23. 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.

XXV Pellet Stove
The XXV Pellet Stove is capable of manual operation. This also allows the opera-
tor to manually control operation during an emergency (i.e. igniter failure, when using
a 502H battery backup instead of the 512H, or when using certain generators.)
The unit can be switched between "AUTO" and "MANUAL" at any time during
operation.

The difference between "AUTO" Room Temperature
Mode and "Manual" Room Temperature Mode 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.
Feed rate adjustments and dial settings are the same
as "AUTO" settings. The blower will shut off com-
pletely if the temperature on the ESP is too low.
Igniter Switch to "MANUAL"
Stove Temperature Mode
The advantage of this mode is to allow the operator
tohavealargeviewingrewithoutblowingextraheat
into the room.
During operation, with the temperature dial set at
#5 or less, the distribution fan will not operate. A #5 on
the temperature dial and a #5 on the feed adjuster is
approximately 80% output. It is not necessary to oper-
ate the distribution blower below this point. This control
setting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 Manual Stove Tem-
peratureModeisifyouwanttowatchalargereand
the room is already up to temperature. The Stove
TemperatureModeallowsyoutohavealargerreand

NOTE: During the use of this mode, if you keep
increasing the temperature dial setting to increase
the re size, the distribution blower will automati-
cally come on when the ESP Temperature reaches
350
o
F, or 81% output.
NOTE: When starting the unit in the "AUTO"
mode and switching to "MANUAL", the re must
be large enough to start the distribution blower.
The starting of the blower is a signal that the start
cycle is completed and the re will not go out.
