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.

XXV Pellet Stove

Installing

Place the stove on a noncombustible

oor protector that extends a minimum of

6 inches to the front, 2 inches to the sides

and ush with the rear of the hopper. Ash

protection must also be positioned under any

horizontally run ue pipe. The minimum oor

protector material is 20 gauge sheet metal.

Other oor protector materials are ceramic

tile, stone, brick, etc.

Place the stove away from combustible

walls at least as far as shown in Figures 2, 3

and 4.

Note that the clearances shown are min-

imum for safety but do not leave much room

for access when cleaning or servicing. Please take this into

account when placing the stove.

Connect the power cord to a 120 V.A.C. 60Hz ground-

ed receptacle. (A surge protector is recommended to protect

the circuit board.) If the voltage entering your home is below

116 volts your stove may not work properly. Also be sure

that the polarity of the outlet that the stove is plugged into

is correct.

Prior to installing the ue pipe, connect a draft meter.

(The draft meter must have a minimum range of 0-.5.)Re-

cord the rst reading. Connect ue pipe to stove and be

sure all doors and windows in the home are closed. Record

the second draft reading_______. If the second reading

is more than .05" lower than the rst reading, check for

possible restrictions or the need for outside air (see page

8). For more information on the draft test procedure, refer

to Page 20.

Mobile Home Installation

When installing this unit in a mobile home several re-

quirements must be followed

(Reference HUD Regulation

#24CFR3280)

1. The unit must be bolted to the oor. This can be done

by using clips (part # 2-0-677110) and 1/4" lag screws.

2. The unit must also be connected to outside air. See

page 8.

3. Floor protection and clearances must be followed

as shown.

4. Unit must be grounded to the metal frame of the

mobile home.

CAUTION: This appliance must be vented to the out-

side.

Due to high temperatures, the stove should be placed

out of trafc and away from furniture and draperies.

Children and adults should be alerted to the hazards of

high surface temperatures and should stay away to avoid

burns to skin and/or clothing.

Young children should be carefully supervised when

they are in the same room as the stove.

Clothing and other ammable materials should not be

placed on or near this unit.

Installation and repair of this Harman stove should be

done by a qualied service person. We recommend that

the stove be inspected before use and at least annually by

a qualied service person. Periodic cleaning is required

throughout the heating season and at the end of each winter

for the stove to work efciently. See cleaning instructions

on page 21.

Requirements for Terminating the Venting

WARNING: Venting terminals must not be re-

cessed into a wall or siding.

NOTE: Only the Harman Direct Vent Wall Pass-

through (part # 1-00-677077) or PL listed vent pipe

wall pass-throughs and re stops should be used

when venting through combustible materials.

NOTE: Always take into consideration the ef-

fects of the prevailing wind direction or other wind

currents that may cause yash and/or smoke when

placing the termination vent.

In addition, the following must be ob-

served:

A. The clearance above grade must be a min-

imum of 18".1

B. The clearance to a window or door that

may be opened must be a minimum of 48" to the

side, 48" below the window/door, and 12" above the

window/door.1

( with outside air installed, 18” )

C. A 12" clearance to a permanently closed

window is recommended to prevent condensation

on the window.

D. The vertical clearance to a ventilated soft

located above the terminal within a horizontal dis-

tance of 2 feet (60 cm) from the center-line of the

terminal must be a minimum of 18".

E. The clearance to an unventilated soft must

be a minimum of 12".

F. The clearance to an outside corner is 11"

from center of pipe.

G. The clearance to an inside corner is 12".

H. A vent must not be installed within 3 feet

(90 cm) above a gas meter/regulator assembly

when measured from the horizontal center-line of

the regulator.1

I. The clearance to service regulator vent outlet

must be a minimum of 6 feet.1

J. The clearance to a non-mechanical air supply

inlet to the building or the combustion air inlet to any

other appliance must be a minimum of 48”.1

K. The clearance to a mechanical air supply

a minimum of 7 feet.1,2

M. The clearance under a veranda, porch, deck

or balcony must be a minimum of 12 inches.1,3

NOTE: The clearance to vegetation and other

exterior combustibles such as mulch is 36” as mea-

sured from the center of the outlet or cap. This 36”

radius continues to grade or a minimum of 7 feet

below the outlet.

1Certain Canadian and or Local codes or regu-

lations may require different clearances.

2A vent shall not terminate directly above a

side-walk or paved driveway which is located be-

tween two single family dwellings and serves both

dwellings.

3Only permitted if veranda, porch, deck, or bal-

cony is fully open on a minimum of 2 sides beneath

Venting

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 di-

ameter 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 (also 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 only 3 inches. The sec-

tions 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

unless the unit is being installed with the optional

top 6" Flue Adapter.

If using 6" Flue Adapter, it is recommended to

use a sealed seam 6" ue pipe (snaplock seam

is not recommended) and seal the joints with high

temperature silicone.

In some cases it may be necessary to use a liner

in the existing chimney to obtain proper draft.

Outside Air

Here are four benets of outside air:

1. Having air introduced from outside the living

area boosts overall efciency.

2. It eliminates draft problems that can occur in

tight homes.

3. It reduces 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.

HRV

When installing in a house with a Heat Re-

claiming Ventilation System (HRV) be sure the

system is balanced and is not creating a negative

pressure in the house.

Direct Vent Wall Passthrough

The Harman Direct Vent Wall Passthrough

(Part # 1-00-677077) makes installing your Har-

man Pellet Stove with outside air a lot easier. It is

made to t walls from 4 1/2" up to 10 1/8" thick with

a square opening of 6" to 6 1/2".

#1 Preferred method (Fig. 8)

This method provides excellent venting for

normal operation and allows the stove to be in-

stalled 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

wall pass-throughs.

concealed space, or a oor, or ceiling.

Fig. 11

#2 Preferred method (Fig. 9)

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 18" above grade. The

outlet must also be 1 foot from the house/building.

Note: Do not place joints within wall pass-

throughs.

CAUTION

Keep any materials that may be affected by the

elevated exhaust temperatures at least 3 feet

away from the ue termination.

#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.

#4 Installing into an existing chimney

with optional top discharge 6" ue

adapter

This method will allow single wall 6" ue pipe

to come off the top of the stove and go directly into

a masonry or class A chimney.

This method will be desireable for people who

are replacing a wood or coal stove and have an

existing chimney to use.

#5 Installing into an existing replace

chimney (US and Canada)

This method provides excellent venting for nor-

mal operation. This method also provides natural draft

in the event of a power failure.

In Canada and some places in the US it is re-

quired 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.

#6 Installing into an existing

chimney (US and Canada)

This method provides excellent venting for nor-

mal operation. This method also provides natural

draft in the event of a power failure.

In this method a cap should also be installed

on the chimney to keep out rain.

12 XXV Pellet Stove

#7 Installing into an existing chimney

using 3" pl 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 a pl type 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

Pipe manufacturer clearance to combustibles,

NFPA and or any local codes must be followed for this

type of installation. Be sure to check with the pipe

manufacturer for clearance to combustibles.

#8 Installing through the ceiling

Through the ceiling vent, follow PLvent

manufacturers recommendations when using a wall

or ceiling pass through. Note: Do not place joints

within wall pass-throughs.

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 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 would 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

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 powercord 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.

During operation, with the temperature dial set at

around #5 or less, the distribution fan will not operate.

A #5 on the temperature dial and a #5 on the feed ad-

juster 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 Manual Stove

Temperature 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

a lower sound level, without the distribution blower.

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

350o F, or 81% output.

Feed Adjuster Knob

For most premium grade pellet fuels the Feed Adjuster

Knob should be set at 4. If higher ash fuels are used the

setting should be increased to 5 or 6. 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 7/90° and the feed adjuster at

6) 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

adjuster knob down to a lower setting.

This setting, see above, will produce continuous maximum

heat output with the distribution blower at full speed.

Stove Temperature Mode

The setting, see above, will produce continuous medium

heat output with the distribution blower at low speed.

AUTOMATIC IGNITION/OPERATION

Shut Down Procedure

The best way to shut down the stove is 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.

Igniter Switch to"AUTO"(up position)

Make sure the unit is plugged into a 120 VAC, 60

HZ electrical source. The power light should be the

only light lit.

1. Turn Mode Selector to "OFF".

2. Fill hopper with pellets.1

3. Clean burn pot with scraper, if necessary.5

4. If starting after an empty hopper, turn Feed

Adjuster to "TEST" (for one 60 second cycle).2

This will purge pellets into the auger tube and also

allow you to check the motors for operation.

NOTE: The auger motor will not operate with

the view door or ash pan door open.3

5. Turn Feed Adjuster to #4.4

6. Flip the Igniter Switch up into the "AUTO"

position.

7. Turn the Temperature Dial to desired room

temperature.

8. Turn Mode Selector to Room Temperature or

Stove Temperature.

9. Fill hopper with pellets and remove ashes as

required.6

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.

Starting Fire

XXV Pellet Stove

The XXV Pellet Stove 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 "MANUAL" at any time during

operation.

Igniter Switch to "MANUAL"

Room Temperature Mode

The re will have to be lit with starting gel and a

match, or started automatically, see "Automatic Op-

eration" on Page 15. Turn to "Manual" position when

the re is established.

The difference between "AUTO" Room Tempera-

ture 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 set-

tings are the same as "AUTO" settings. The blower

will shut off completely 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 op-

erator 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 ap-

proximately 80% output. It is not necessary to operate

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

Temperature 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

a lower sound level, without the distribution blower.

NOTE: During 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

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.

MANUAL IGNITION/OPERATION

This setting will produce a large viewing re

without a distribution blower operating.

(down position)

Make sure the unit is plugged into a 120

VAC, 60 HZ electrical source. The power light

should be the only light lit.

1. Turn FEED ADJUSTER to desired feed rate.

No. 4 is good for most pellets.4

2. Turn the MODE SELECTOR to “OFF” and

then to the desired mode. This will reset con-

trol and start the combustion motor.

3. Turn the TEMPERATURE DIAL to the desired

setting.

4. Clean burn pot with scraper if necessary.5

5. Fill burn pot with pellets, only level with front

edge. (Do Not Over Fill).

6. Add starting gel on top of the pellets. Stir gel

into pellets for fast lighting.

7. Light starting gel with a match, and close the

door. Operation will begin when the re reaches

the proper temperature.3

8. Fill hopper with pellets and remove ashes

WARNING

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.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 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. 26. This is a conservative
