The Award-Winning P68 Pellet Stove has the widest BTU range available, giving you 0 to 68,000 BTU

when you need it, automatically. The only thing you need to do is set your desired room temperature and

llthehopper.WiththeP68youwillnoticeevenheatthroughoutyourhomeandalevelofconvenience

you never thought possible.

The P68 epitomizes the capability of Harman Pellet Stoves, taking advantage of Harman’s 20 years

of pellet stove design, technology and manufacturing. This 68,000 BTU stove has the highest output,

smartest controls, widest heating range, and minimal maintenance. The P68’s huge output is managed by

amicroprocessorthatsensestheroomtemperatureandtheretemperaturewithtinythermisterprobes

and then determines the best feed rate. This improved and smarter control also has a diagnostic port for

connecting an external display showing live working data for easier troubleshooting.

The platinum combination is Harman’s Patented Feeder & Burn Pot, and ESP Control which have been

developed to their highest state. These features work together to allow amazing heat output with different

fuel quality, ash content and moisture.

Requirements for Terminating the Venting

WARNING: Venting terminals must not be re-

cessed into a wall or siding.

NOTE: Only PL vent pipe wall pass-throughs

andrestopsshouldbeusedwhenventingthrough

combustible materials.

NOTE: Always take into consideration the effects

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 observed:

A. The clearance above grade must be a mini-

mum of 18".

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.

( 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 distance

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 regu-

lator.

I. The clearance to service regulator vent outlet

must be a minimum of 6 feet.

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”.

K. The clearance to a mechanical air supply inlet

must be a minimum of 10 feet.

(with outside air installed, 6 feet )

L. The clearance above a paved sidewalk or a

paved driveway located on public property must be 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.

Certain Canadian and or Local codes or regula-

tions may require different clearances.

A vent shall not terminate directly above a side-

walk or paved driveway which is located between two

single family dwellings and serves both dwellings.

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

cony is fully open on a minimum of 2 sides beneath

theoor.

NOTE: Where passage through a wall, or partition

of combustible construction is desired, the

installation shall conform to CAN/CSA-B365. (if

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)

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 3 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. For this reason and

the fact that the P68 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 1ft. or more from the outlet of the

stove.

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.

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 combustible materials (such as grass,

leaves, etc.) at least 3 feet away from the ue

outlet on the outside of the building.

#1 Preferred method

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

P68 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 P68 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

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.

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increase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 the

precise temperature you desire.

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 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 17.) 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

P68 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 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.

During manual 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 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

350

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.

P68 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.

The setting above will produce continuous maximum heat

output with the distribution blower at full speed.

Stove Temperature Mode

The setting above will produce continuous medium heat

output with the distribution blower at low speed.

2. Fill hopper with pellets.

3. Clean burn pot with scraper, if necessary.

4. If starting after an empty hopper, turn Feed

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

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.

5. Turn Feed Adjuster to #4.

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

9. Fill hopper with pellets and remove ashes as

required.

P68 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. 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 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. 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.

P68 Pellet Stove

The P68 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, as opposed to the 512H, or when using certain generators.)

The unit can be switched between "AUTO" and "MANUAL" at any time during

operation.

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.
