4Harman Oakwood
Thank you for purchasing the Harman Oakwood. We are condent that you will enjoy the warmth and con-
venience of your Harman Stove for decades to come.
The Harman Oakwood will heat your home while also being multi-functional and visually appealing. When
building your Oakwood, we used only the best precision castings that were designed, so accurately, that
gaskets are used (instead of furnace cement) for assembly.
Harman’s special FireDome, Non-Catalytic, Combustion System was created specically for the Oakwood to
promote clean burning and even heat output. What this equates to is unvarying heat throughout your home over
a longer period of time without the peaks and valleys of other wood stoves. The FireDome attains Harman’s
reputation of high efciency while saving you the expense associated with catalytic stoves. Top loading makes
adding wood easier and allows you to view your beautiful re through the extra large glass door. The glass
stays cleaner because of specially coated glass and the exclusive Harman Air Wash System.
The Harman Oakwood has an ash pan with its own ash door that is used to remove ashes while the stove is
in operation. This means you can keep one re all winter if you desire.
The Harman Oakwood offers a cooking grill that can be placed in the top of the stove while in operation. This
allows you to grill steaks and burgers etc. all year long, even when the weather is not suitable for outside
grilling. If you haven't already purchased the cooking grill, you can do so through your Harman Dealer.
Due to the fact that the Oakwood is hot while in operation, gloves should be worn while tending to the re.

The Stove
Doors
Your stove has a large glass-paneled door for loading
and re viewing, a separate smaller door for removing
ashes and a top loading door.
Front Door
Before opening, always check for wood, embers, or
ash that may be ready to fall out of the door.
To open the glass door, open the bypass damper rst,
then lift the handle and pull out; to close the door, push
the door closed with the handle in the open position, then
push the handle down to engage the latch.
Ash Door
To open the ash door, lift up the handle and pull out.
Close the door by pushing in and pushing the handle all
the way down.
Top Load Door
To open the top load door, open the bypass damper
and then lift to open the top load door.
All doors must be closed while the stove is in normal
operation, and the gaskets routinely examined for wear
andreplacedwhennecessary. Gooddoorsealsareimpor-
tant for maintaining control of the stove. Never operate
with the ash door open. Operating the stove with the ash
door open, or with a door inadequately sealed, could
create a serious overring condition (discussed later in
this section).
NEVER OPERATE WITH MORE THAN
ONE DOOR OPEN ATATIME
The glass used in your Oakwood is manufactured to
exact standards to withstand the high heat of the re, but
like all glass, it must be treated with common sense and
care. Never abuse the glass by slamming the door shut
or striking the glass with a heavy object. If the glass is
broken or damaged, do not operate the stove until it has
been replaced
(See instructions in the Maintenance section.)
Grates
The Harman Oakwood's unique grate system consists
of one at bottom grate, and two front andirons. The bot-
tom grate has slots which allow the ash to fall into the ash
pan by passing a poker back and forth across the grate.
The andirons keep the fuel from coming into direct con-
tact with the glass, and keep hot coals and embers from
spilling out while reloading. Never build a re directly
against the glass.
The grates and andirons must remain in place at all
times. Do not tamper with or change the conguration
of this grate system.
GeneralConsiderations
Draft
Before you install and operate your Oakwood
wood stove, please read the entire contents of this
manual. Pay particular attention to the explana-
tion of draft and its effect on stove performance in
the Installation section. By following the installation and
operatingguidelines,youwillensureproperdraftandgain
maximum efciency and enjoyment from your stove.
Fuel
Your Oakwood burns wood very efciently. Here
are some guidelines that will help you achieve the best
performance.
Select only dry,seasonedwood. Wood for burning
should never be exposed to rain or extremely damp con-
ditions. Hardwoods are favored because they are heavier
and contain more heating capacity (BTU’s) per load than
dosoftwoods. Fuelwoodshouldbesplitandstoredunder
cover for “seasoning” - at least a year is recommended.
Your stove is not an incinerator - do not burn garbage,
painted or treated wood, plastic, or other debris.
Keepthe area aroundthestovefree from clutter. Keep
allcombustibles,includingfuel,beyondthecode-required
clearance distance (48" or 1215 mm in the U.S., 1525
mm or 60" in Canada). Never store fuel in front of the
stove where it could interfere with door operation, safe
loading, and ash removal.
Donotburngarbageorammableuidssuch
asgasoline,naptha,orengineoil.
CAUTION:
Alwayswearreretardantgloves
whenoperatingthestove.

TheCombustionProcess
Combustion in the Harman Oakwood is precisely con-
trolled and is best explained in two parts.
During a wood re, combustion air enters at the bottom
front of the stove where it travels upward through channels
at either side of the front door. From the manifold located
above the front door, it is directed into the rebox as a sheet
of air owing between the glass and the wood. This concept
helps to keep the glass clean, while providing the oxygen
needed to sustain burning. This is what is known as "Primary
Combustion".
Additional air enters at the bottom rear of the stove body.
Someofthisairentersthroughholes in the rearbrickswhere
it is used to revitalize the re at the rear of the rebox. The
remainder is delivered into the "Firedome" combustion
package where the "Secondary Combustion", or re-burning
of the smoke, occurs.
During combustion, the burning of wood proceeds
through several stages. The initial or evaporation stage is
where the moisture in the wood is driven off in the form of
steam.A second stage is where the volatile gases contained
in the wood are released and burned.This represents most of
the wood's heating capacity. The nal stage is the charcoal
stage where the charcoal burns the remaining heat content
in the wood fuel.Ash remains after the burning is complete.
Within the primary rebox two or more of these stages of
combustion are occurring at once.
Two important controls - the damper bypass handle and
the air control lever regulate the operation and output of the
stove.
To open the top or front loading door, you must open
the damper bypass, or smoke will come in the room. In this
mode of operation the combustion gases go directly from
the main combustion chamber to the ue collar and exit into
the chimney.
NOTE:Thebypassdampermustbeopenforsmoke-
lessloading. Open the bypass damper by turning the handle
clockwise while facing handle.

Air Control
The air control lever is located directly below the ash
lip of the stove. Sliding this lever allows you to vary the
amount of air to the re, creating a range of heat outputs.
The lowest heat output setting is to the left, and the high-
estis to theright.The notchesare provided asa reference
for your comfortable heat settings. Do not, under any
circumstances, alter the conguration or operation of
the air control lever.
For low burn, slide the air control to the left. For
medium burns, use notches 4,5 & 6. Maximum heat is
attained with the air control all the way to the right. Do
not burn the stove continuously at the maximum setting.
If maximum heat is required day after day, the stove is
too small for the area you are trying to heat.
If your wood is not seasoned long enough or is high
in moisture content, you may need to adjust the primary
air 1 or 2 notches higher to sustain a low burn rate with
the cleanest possible exhaust.
Building and Maintaining the Fire
Donotusechemicalsoruids
tostartthere.
Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter uid, or similar liquids to
start or “freshen up” a re in this heater. Keep all such
liquids well away from the heater while it is in use.
Building a Fire
Begin with the bypass damper open, and the air
control lever at the maximum setting, all the way to the
right. Be sure the ash pan door is closed and latched.
Start with abedofcrumpled paperandkindlingsized
about nger width; place several 1" - 2" (25mm - 50mm)
splitpiecesofdrywoodontopofthekindling,followedby
a few 2" - 3" (50 mm - 80 mm) split pieces. Lay the wood
in a crossed pattern to allow maximum air ow. Ignite
the paper and close the loading door(s). Allow this start-
up re to burn for a few minutes, keeping the bypass
damper open. Add about ve more pieces of wood in
the 2 to 3 inch (50 - 80mm) size range, making sure
that the fuel bed is all the way across the rebox and
staggered to allow airow. Close the door and allow
this loading to burn a few minutes.
Add increasingly larger pieces of wood to the re
untilyouhavea thickbedofhotembers,approximately
2 to 3 inches deep at the back of the grate and at least
an inch deep at the front. Youmusthavethischar-
coal bed established before you close the bypass
damper.
Providing you have the charcoal bed described
above, close the bypass damper by pulling the handle
toward the front of the stove.This will begin the highly
efcient mode of operation where the exhaust gases get
re-burned inthe secondary combustionpackage.If you
cannot achieve a charcoal bed within the rst 15 to 20
minutes,yourwoodislikelytoowet,andyoumayneed
to burn the re longer and/or hotter to compensate for
the extra energy needed to drive out the moisture.
If, after ve minutes of burning with the damper
closed, smoke is visible coming from the chimney,
you probably do not have the proper coal bed. Open
the bypass damper and continue with the process until
a signicant coal bed is formed.

BUILDING A FIRE
Always remember to open the bypass damper when
you are loading, this allows the exhaust gases to pass
directly into the ue outlet and reduces the chance of
smoke spillage into the room.
Reloading: Onceyouhavepreparedandmaintained
a thick charcoal bed, and the secondary combustion is
established, you should be able to reload the stove at
any time by simply opening the bypass damper, then
the load door, adding fuel and closing the door then
the damper. This depends on coal bed size, load size
and moisture content of fuel.
RemovingAshes: Before reloading, empty the ash
pan (remember to close the ash door while emptying
the pan). The ashes should be the coolest at this time.
Remove ashes from the re chamber periodically by
raking a poker across the bottom grates.
Excessive ash buildup can prevent proper venting
of exhaust gases. Do not allow the ash pan to over-ll.
Ash buildup between the ash pan and the bottom of
the grate can cause the grate to overheat and wear out
prematurely.
TheOakwoodwasdesigned toprovideaccess tothe
ash pan without the need for opening the main door.
Beforeopening theashdoorandremovingtheashpan,
open the bypass damper. Wearing heavy protective
gloves, open the ash door and remove the ash pan by
pulling it forward by the handle. Close the ash door
and damper bypass before taking the ashes outside for
safe disposal.
Ashes should be placed in a metal container with a
tight tting lid. The closed container of ashes should
be placed on a noncombustible oor or on the ground,
well away from all combustible materials, pending
nal disposal. If the ashes are disposed of by burial
in soil or otherwise locally dispersed, they should be
retained in the closed container until all cinders have
thoroughly cooled.
Never use the ash disposal container for other trash.
Wood ash can be added to your garden or compost.
Overring
Avoid overring your stove. Overring is a poten-
tially hazardous situation which can lead to overheat-
ing of combustible materials nearby, damage to the
stove, and in extreme cases, cause a re. Overring is
caused by: 1. Too much air owing through the stove
too quickly. 2. You may have positioned the primary
air control lever too far to the right. 3. Inadvertently
leaving the damper open or 4. Not keeping up with
routine maintenance, such as checking door gaskets
for wear.
Overring results in excessive fuel consumption,
and may cause parts of the stove or chimney connector
to glow red. If you notice signs of overring, reduce
the air supply to the re, and review the Maintenance
section in this manual.
In the event of a chimney re, call your local re
department; make sure everyone is safely out of the
house. Reduce the air intake of the stove as much as
possible using the air control lever; close the bypass
damper to further restrict air ow. Do not throw water
on the re; this can cause stove damage and create an
even more dangerous situation. Have your chimney
professionally cleaned and inspected before resuming
burning in your stove.
As you begin to operate your stove at higher tem-
peratures, you will notice a “hot” or unpleasant smell;
this is just the paint going through the curing process,
and will disappear after a few res.
