Introduction
Congratulations! You have just invested in a mostunique wood burning stove – the Heritage Wood
Burning Stove from Hearthstone Quality Home
Heating Products, Inc®. The Heritage Model 8021
is a clean burning, EPA certified, non-catalytic woodburning stove. With a 2.2 cubic foot firebox capacityand 2.6 grams per hour particulate emission, you
can be proud to join the Hearthstone family with our
Premier Soapstone Wood Burning Stove. The front
and the side doors, along with the generous depth
allow for loading of wood up to 21 inches long!
Your purchase ensures years of clean, comfortable
heat with minimal maintenance. You will receive thebenefits of the most advanced technology in woodburning without the cost and maintenancerequirements of a catalytic stove. The Heritage
blends modern technology with the unique beautyand heating qualities of soapstone, long known for
its even heat production and long heat-retaining
ability. We trust that you will appreciate the quality of
our handcrafted product.
Please read this manual in its entirety. Its purpose
is to familiarize you with your stove's safe
installation, proper break-in, operation andmaintenance. It contains information that will be
useful to you now, and in years to come, so keep it
handy and refer to it as needed.
Use these instructions as well as national, state, andlocal building codes to install your stove. Be sure to
maintain the designated stovepipe and stoveclearances to walls, ceilings, hearth, and othercombustible surfaces. This will help reduce the riskof fire. Failure to follow these instructions can resultin property damage, bodily injury, and even death.
Locate your stove in a safe, convenient, open area;
away from traffic flow, doors, and hallways; and neara chimney and chimney connector. Review theproper clearance measurements from combustible
surfaces. You can safely reduce required clearances
in most cases by using the, optional, rear heatshield, and also with a special connector pipe andspecial wall coverings as specified by this manual,
the NFPA 211 codes, and your local authorities
having jurisdiction.
Keep furniture, drapes, curtains, wood, paper, andother combustibles far away from the stove. Neverinstall the stove in a location where gasoline,
kerosene, charcoal lighter fluid or other flammableliquids are used or stored.
Locate the stove centrally in your living area to allow
the heat to travel naturally to distant rooms. We
recommend that you do not locate your stove in an
uninsulated basement.
The amount of radiantenergy required to heat concrete basement walls is
so great that most of the usable heat is absorbed bythem and lost.

Inspect the stovepipe, chimney connector andchimney, as recommended.

CODES
When you install your Heritage wood stove, it isimperative that you adhere to all local codes, which
can be obtained from either of the following two
National sources:

Follow these safety precautions:
Never modify this stove in any way, especiallythe primary air control system.
Never burn kiln dried wood, painted or treatedwood, solvents, trash, plywood, colored or
glossy paper, artificial logs, cardboard, coal,garbage or driftwood. Especially, do not burncoal in this stove.
Never use gasoline type fuel, kerosene,
charcoal lighter fluid, or other liquid fuels or solid
fire starters to start or invigorate the fire. These
fuels can possibly generate carbon monoxide,
which can deplete the supply of oxygen. Keepall such materials away from the stove.
Never use the stove if the ash pan door is open,
damaged, not in place, or not sealing.
Never use a wood grate or other device toelevate the fire.
Do Not allow wood to rest against or otherwise
come in contact with the glass when the door isclosed.
Do Not slam the door or use the door to force
wood in to the stove.

If you are installing your Heritage in a mobile home,follow the guidelines described in the Manufactured
Home Construction and Safety Standard, Title 24
CFR, Part 3280 (United States).

SAFETY INFORMATION
Read and understand this Owner's Manual
thoroughly before installing and using thisstove.
Ensure you install your stove:
Accordingtothemanufacturer's
recommendations.
In accordance with all applicable codes.
With the proper sized chimney.
When using your stove:
Warn children and others unfamiliar withwoodstoves of the danger of touching hot,radiating surfaces of your stove. For youradditional safety, obtain hearth and stove guards
through your local dealer.
Follow recommended break-in procedure as
outlined in this manual.
Burn natural wood only. Higher efficiencies andlower emissions result when burning air-dried,seasoned wood, as compared to green or
freshly cut wood.
Use caution when loading firewood into a hot
stove.
Keep the side and front doors closed at all times
except when loading wood.

Other safety guidelines

Hearthstone Quality Home Heating Products, Inc. ®

As a general rule, keep all movable combustible
items such as furniture, drapes, clothing, andother items, at least 36" (0.92 m) from the stove.
Install a good smoke detector, preferably in anarea away from your wood stove.
Keep a fire extinguisher handy. We recommend
the type rated "A B C."
Dispose of ashes properly. (See page 22)
Keep children and pets away from the stove;
they could be burned by touching a hot stove.
Clean your chimney system as needed. (Seepage 23)

WARNING: DO NOT ATTEMPT TO PUT OUT ASTOVEPIPE OR CHIMNEY FIRE BY THROWINGWATER ONTO THE STOVE, STOVEPIPE, OR
CHIMNEY.
THE
EXTREMELYHIGH
TEMPERATURE ASSOCIATED WITH SUCH FIRESCAN CAUSE INSTANTANEOUS STEAM AND
SERIOUS BODILY HARM.

PERIODIC CHECKLISTPerform each of these tasks at the specified
intervals.
At the End of Every Week:
Empty ashes from the firebox and ash pan,sooner if the firebox or the ash pan begins to fillup.
At the Beginning of Every Other Month:
A visual inspection of the chimney connector
and chimney for creosote is recommended
depending upon your use of the stove. (Pleasesee page 23)
Check door seals using the "dollar bill test." When the fire is out and the stove is cool, shutthe door on a dollar bill. If the bill pulls out
without any resistance, then your stove’s door
isn't sealed properly. To tighten the seal,change the door gasket. (Refer to page 23.)

Once the chimney fire expires, leave the primary
air control closed and let the fire in the stove dieout completely. You should not fire the stoveagain until the stove, stovepipe, and chimney are
all thoroughly inspected for any sign of damage.
You must correct any damage before using yourstove again.

HEARTHSTONE’S THERMO-CERAMICBAFFLE SYSTEMAt the End of Every Season:
Dismantle the chimney connector and clean it
thoroughly. Replace any pieces that show signsof rust or deterioration.
Inspect and, if necessary, clean your chimney.
Thoroughly clean out the inside of the stove.
Inspect all door gasket material and replace ifworn, frayed, cracked or extremely hard.

To enhance the combustion efficiency and reduce
the emissions of the fire in your stove Hearthstone
has developed an advanced THERMO-CERAMIC
baffle system. This system uses a lightweight,
durable ceramic material above the burner tubes tomaintain the high temperatures in the secondary
combustion area and maintain the low emission –high efficiency combustion you desire. This newtechnology will not corrode, rust dissolve or lose its
strength, however it is vulnerable to puncture orcracking due to rough handling.

EMERGENCY PROCEDURES
If you have a stovepipe or chimney fire, follow these
instructions:
1. If the fire is too threatening, leave the area andcall the fire department immediately! If not,perform the next three steps.
i.
Close the primary air control.
ii.
Close the stovepipe damper (if present).
iii.
Keep the stove front, side and ash doors
closed!

PLEASE EXERCISE CARE WHEN LOADINGWOOD OR CLEANING YOUR STOVE, NOT TODAMAGE THE THERMO-CERAMIC BAFFLE

Located directly above the burner tubes in thefirebox, this white or grey sheet of ceramic material
will break if wood or cleaning brushes impact it. Be
careful when loading and cleaning your stove to notbreak this material. If this piece is fractured or a holeis punctured, the stove will function improperly. You
must order a replacement baffle kit through aqualified Hearthstone dealer.

Read this chapter to obtain a sound understandingof how to properly install your stove.

INSTALLING YOUR STOVEFirst, you must decide where your stove will reside.
After choosing an appropriate spot, inspect thislocation to make sure that the stove will haveenough clearance to combustible materials thatwould surround the stove. These combustibles can
include walls, floor, ceiling, fireplace, and chimney.
You must carefully consider the clearances to all ofthese combustibles before actually connecting yourstove. When considering these clearances, alsodecide the kind of floor the stove will rest on. Unless
it is being installed on non-combustible flooring, afloor protector with an R-value of 1.2 is required.
Please use this section to plan how to locate yourstove in your particular location. Consider both theclearances of the stovepipe and the stove itself tothe surrounding combustibles. Also consider accessto the side door.

HEARTH REQUIREMENTS AND FLOORPROTECTION
Combustible flooring must be protected with acovering of noncombustible material with an R-valueof 1.2 (slate, marble tiles, or other noncombustible
material can be used for this purpose). The floor
protection must extend beyond the body of thestove at the minimum as follows: LEFT SIDE 16” (41 cm)*
 RIGHT SIDE 5” (13 cm)
 REAR 2” (5 cm)**
 FRONT 16” (41 cm)*
* Installations in Canada require 18” (46 cm) of floor protection
on the left side and front.
** Rear clearance required only if stovepipe runs horizontally backfrom the top or rear of the stove.

The soapstone walls of the Heritage soapstone
stove produce an even radiant heat. Locate thestove centrally in your living area to allow the heat totravel naturally to distant rooms. It is notrecommended that you locate your stove in an
uninsulated basement. The amount of radiantenergy required to heat concrete basement walls is
so great that most of the usable heat is absorbed bythem and lost.
If you use a close clearance connector pipe, it must
be tested to UL standards and listed. Check thelisting of your pipe for actual clearances. The
diagrams in this manual represent typicalinstallations, but are specific to the Simpson DuraVent DVL brand. Clearances cannot be reduced
without the use of close clearance connector pipe
and/or by protecting the surfaces per NFPA 211
standards.

Figure 4 – Hearth Pad Dimensions
Note: Dimensions shown in figure above are measured from thebody of the stove, not the legs.

Page 8 of 30

Minimum hearth pad dimensions can be reduced byinstalling the Side Door Lock Kit (Kit 90-70210).
(Minimum hearth pad width with the lock kit is34”).
Floor protector’s come with various types of
specifications. To convert a floor protector’s
specification to an R-value, do one of the following:If the R-value is given, use that value—noconversion is needed.
If a K-factor is given with a required
thickness (T) in inches, use this formula:
R-value = 1/K x T
If a C-factor is given, use the formula:
R-value = 1/C

Handle Operation
Front Door – when closed, the handle is in the 7o’clock position. To open the front door, rotate thelatch clockwise to approximately the 10 o’clock
position.
Ash Pan Door – when closed, the handle is in the 9o’clock position. To open the ash door, rotate thelatch counter-clockwise to approximately the 7’clock
position.
Side Door – when closed, the handle is in the 5o’clock position. To open the side door, rotate thelatch counter-clockwise, to approximately the 2o’clock position.

To determine the R-value of the proposed alternate
floor protector:

Use either the K-factor or the C-factor
formula explained above to convert
specifications not expressed as R-values.
For multiple layers of floor protectors, simply
add the R-values of each layer to determine
the overall R-value of the layers.

If the overall R-value of your setup is greater thanthe R-value of the specified floor protector, then yoursetup is acceptable.

An outside air source may be connected directly tothis stove using an optional outside air kit. The
advantage of providing outside air directly to thestove is that the air used by the stove for combustion
is taken from outside of the residence rather thanfrom within the room where the stove is located.
With outside air supplied directly to the stove, drafts
within the room and air infiltration within the building
are reduced. Use of the outside air kit may also
improve stove performance in a particularly airtighthouse.

structural members of the house. The outside air kit
attaches to the bottom, back of the stove.
Locate the termination of the duct on the outside
wall in such a manner so as to preclude thepossibility of obstruction by snow, leaves or othermaterial. Screen the termination against animals andinsects using ¼” x ¼” mesh rodent screen and cover
it with a rain/wind proof hood (flex pipe, outside
termination, mesh, and hood supplied by others).
Contact your dealer for availability.

CLEARANCES TO COMBUSTIBLES
It is very important to follow minimum clearances forchimney connectors to combustibles such as walls
and ceilings when installing the stove nearcombustible surfaces.

the venting system. Upon inspection, immediately
replace rusted, cracked, or broken components.
The chimney connector is the stovepipe from thewoodstove to the chimney.
The chimney
connector stovepipe must be 6" (152 mm)diameter, 24 MSG or 25 MSG blued steel
connector pipe.
Do not use aluminum or
galvanized steel pipe - they cannot withstand theextreme temperatures of a wood fire.
A thimble is a manufactured (or site-constructed)
device installed in combustible walls throughwhich the chimney connector passes to thechimney. It keeps the walls from igniting. You
must use a wall thimble when installing achimney connector through a combustible wall tothe chimney.
A wall pass-through (or chimney support
package) also keeps the walls from igniting. You
must use one when connecting through a wall or
ceiling to a prefabricated chimney.
Only install this stove to a lined masonry chimney
or an approved high temperature prefabricatedresidential type building heating appliancechimney. Do not connect this stove to a chimney
serving another appliance; you will compromise
the safe operation of both the wood stove andthe connected appliance.

In order to convert the Heritage from a top to rear or
vice-versa, reach through the flue collar andremove the four ¼-20 hex head screws that mountthe cover plate. Next, reach through the hole whole
the cover plate was and remove the four ¼-20 hex
head screws that mount the flue collar. Exchange
the two pieces and reattach the eight screws.
Single wall connector is 24 MSG or 25 MSG
blued steel stovepipe.
Double wall connector (close clearance pipe)
which must be used with a listed factory-built“Type HT" chimney also may be used with amasonry chimney to reduce clearances, isavailable from several manufacturers, yourdealer can help you choose.
Some airinsulated connector pipe models available are
Simpson Dura Vent DVL and Metalbestos DS.
Security, GSW and Ameritec also haveacceptable close clearance connector pipe.
When used in a mobile home, a spark arresteris required. (See page 17)
Chimney connector shall not pass through floor
or ceiling, nor any attic or roof space, closet or
similar concealed space.
Where passage
through a wall or partition of combustible
construction is desired, the installation shallconform to NFPA 211 or CAN/CSA - B365.
It is very important to follow minimum
clearances for chimney connectors to
combustibles such as walls and ceilings when
installing the stove near non-combustible
surfaces.
Typical chimney connector
clearances are outlined below. The single wall
clearances are generic; the Double wall
clearances are for Simpson Dura Vent DVL,CHECK THE SPECIFICATIONS FROMMANUFACTURER OF YOUR CONNECTOR.

THECOMPONENTS OF A VENTING SYSTEM
The complete venting system consists of several
components: chimney connector, wall thimble, wallpass-through, chimney, and liner. It is absolutely
necessary that you install all of these components
within the clearances to combustibles discussed
earlier to install your stove safely.
To protect against the possibility of a house fire,you must properly install and constantly maintain

WARNING: DO NOT CONNECT THIS APPLIANCE
TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.

A liner is the UL 1777 or ULC S635 (for factorybuilt fireplace or masonry) chimney.
You must connect your stove to a chimney
comparable to those recommended in this manual.
Do not use stovepipe as a chimney. Use stovepipe
for freestanding installations only to connect thestove to a proper chimney.

INSTALLING A VENTING SYSTEM
Stovepipe sections must be attached to the stove andto each other with the crimped end toward the stove.
If creosote builds up, this allows the creosote to run
into the stove and not the outside of the stovepipe
and onto the stove.
Secure all joints, including attaching the stovepipe tothe stove's flue collar, with three sheet metal screws.
Install #10 x 1/2" (3 mm x 13 mm) sheet metal screws
into the holes pre-drilled in the flue collar. Leaving off
the screws can cause joints to separate from thevibrations that result from a creosote chimney fire.

You can simplify connecting stovepipe by using
additional accessories such as telescoping pipes,
slip-connectors or clean-out tees.
These
accessories ease the inspection of your chimney,
as well as allow you to easily dismantle thestovepipe (without moving the stove) when you
periodically inspection the stovepipe connection
and chimney.
Install the stove as close as practical to thechimney, while maintaining all proper clearances.
Install stovepipe that is as short and as straight as
possible.
Horizontal runs of stovepipe should
always rise away from the stove a minimum of 1/4"
per foot (21mm/m).
Long runs of stovepipe to increase heat dispersal
are not recommended. Using longer lengths ofstovepipe or more connecting elbows thannecessary increase the chances of draft resistanceand the accumulation of creosote buildup.
In general, you do not need to install a stovepipe
damper with the Heritage. Some installations,however, could benefit from a stovepipe damper,
such as a tall chimney which can create a higher
than normal draft. In such cases, a damper canhelp regulate the draft. The Heritage requires adraft between 0.06" wc and 0.1" wc. For drafts
above 0.1" wc, install a stovepipe damper. Thisshould be checked at installation time.
Remember, the NFPA has recommended, minimum
clearances for chimney connectors to combustibles
such as walls and ceilings. Once the stove isinstalled at safe distances from these combustible
surfaces, it is important to maintain these connector
clearances for the remainder of the installation.

CONNECTING YOUR WOOD STOVE
You can install your Heritage to a prefabricatedmetal chimney or a masonry chimney.

Connecting to a Prefabricated Metal
Chimney
There are two ways to install a prefabricated metalchimney:

discourages the formation of creosote. An exteriorchimney does not benefit from the warmth of being
surrounded by the building, so it typically operates atlower flue temperatures than an interior chimney. An
exterior chimney’s draft is not as strong and may
experience increased creosote accumulation.
When connecting the Heritage to a prefabricatedmetal chimney, you must follow, precisely, themanufacturer's installation instructions. Use only
Type HT (2100 deg. F), prefabricated metal chimneys
listed per UL 103 or ULC S629 standards.
WARNING: DO NOT CONNECT THE STOVE TO A
CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

Ensure the size of the chimney’s flue is appropriate
for the Heritage. The Heritage requires a 6" (152mm) inside diameter flue for new installations. A 6”
diameter flue provides adequate draft andperformance. You can use an 8" (203 mm) diameter
existing flue with a reducer. An oversized flue
contributes to creosote accumulation. (In this case,bigger is NOT better.)
When purchasing a prefabricated chimney to installwith your stove, be sure to also purchase from thesame manufacturer the wall pass-through (or ceilingsupport package), "T" section package, fire-stops(when needed), insulation shield, roof flashing,chimney cap, and any other needed accessories.
Follow the manufacturer’s instructions when installingthe chimney and accessories. In addition, be sure to
maintain all manufacturers’ recommendations for theproper clearances to the chimney.

Connection To A Masonry Chimney
Consider two primary elements when connecting
your stove to a masonry chimney: the chimney itself
and the thimble where the stovepipe connects to thechimney.
Use only Code approved masonrychimneys with a flue liner.
Before connecting to a masonry chimney, hire a
professional to examine the chimney for cracks,loose mortar, and other signs of deterioration andblockage. If the chimney needs repair, complete
them before installing and using your stove. Do notinstall your stove until the chimney is safe for use.

An interior installation where the chimney
passes inside the residence through the ceilingand roof.
An exterior installation where the chimney
passes through the wall behind the stove thenup the outside of the residence.

Make sure the chimney’s cleanout is complete andworking properly. To avoid a loss of draft, thecleanout must close off completely. If allowed tocool, your stove will perform poorly and creosote willbuild up in the chimney.

Whenever possible, choose an interior chimney.
An interior chimney heats up more quickly andretains its heat; thus promotes a better draft andEnsure the size of the chimney’s flue is appropriate
for this stove and that it is not too large. Use amasonry chimney with an 8" x 8" (203 mm x 203 mm)

tile size for best results. An oversized flue willcontribute to the accumulation of creosote.

At least 2" (51 mm) clearance to combustible
Structure
Fire stops must be installed at the spaces where
the chimney passes through floors and/or ceiling.
Insulation must be 2" (51 mm) from the chimney.

Use the following checklist to ensure that yourmasonrychimneymeets

Operation
Once your Heritage is set in place, connected, andassembled, you are ready to light a fire.
Hearthstone Stoves tests each wood stove before
we ship, so you should be able to easily light yourfirst fire.
WARNING: HOT WHILE IN OPERATION.
KEEP
CHILDREN,
CLOTHINGAND
FURNITURE AWAY. CONTACT MAY CAUSESKIN BURNS.
Please read this entire chapter before lighting yourfirst fire. It explains the controls and features of yourwood stove, how to choose firewood, and how tobreak-in your stove and use it on a daily basis.

CONTROLS AND FEATURES
Before lighting any fires, become familiar with thelocation and operation of your stove's controls andfeatures and learn how to use them. For your own
safety, do not modify these features in any way.
FRONT DOOR HANDLE: The front door allows you
to load wood into your stove; a fixed handle allows
you to operate the front door and allows you to latch
the front door closed. To open the door, lift thehandle to the 10 o’clock position and pull the door.
To latch the door, push the door closed tightly thenturn the handle to the 7 o’clock position. Pull on thedoor handle to make sure it is properly latched.
SIDE DOOR HANDLE: The side door allows you toload wood into your stove; a fixed handle allows you
to operate the side door and allows you to latch thedoor closed. To open the door, lift the handle to the
2 o’clock position and pull the door. To latch thedoor, push the door closed tightly then turn thehandle to the 5 o’clock position. Pull on the door to
make sure it is properly latched.

ASH PAN: The ash pan and ash pan access door
is located under the ash lip. To operate the ash
grate, simply attach the ash grate control handle(shipped in your owner’s manual) to the control slide
under the center of the ash lip, with loop facing left.
Rotate the handle counter-clockwise until the handle
is locked in place. Push the handle in to close theash grate, Pull the handle out to open the ash grate.
To unlock the handle simply rotate clockwise. Whenthe ash door is closed, it will automatically close theash grate. (Refer to figure below to see theattachment of the ash grate control handle to thecontrol slide.) The ash pan collects burned ash froma fire and allows you to conveniently remove the ash
from your wood stove. The firebox should becleared of ashes periodically by sliding the ash grate
towards the front door, sifting the ashes across thegrate into the ash pan, then returning the grate to its
closed position.
To access the ash pan, turn the ash door handle
counter-clockwise, and pull the door open. The ash
pan is easy to remove and has a handle forconvenient disposal of ashes. Before removing theash pan, push it (hard!) into the stove, which kicks
the ashes further into the pan. To close the ashdoor, push the door closed and turn the handle
clockwise. Note: The ash grate can only be opened
when the ash door is ajar or open. The ash grate
can be moved back and forth with the shaker grate
handle or from the top with a poker.
Do not operate the stove unless the ASH PAN isinserted into the stove and the ash door isclosed. This could overheat and damage thestove.

Control Slide

ASH PAN DOOR: When closed, the handle will bein the 9 o’clock position. To open the ash door,
rotate the latch counter-clockwise to approximately
the 7 o’clock position.
PRIMARY AIR CONTROL: The handle is locatedon the front lower left of the stove, just under the ash
lip. The primary air control allows you to regulate
the amount of air entering the firebox. Generally,
the more air allowed into the firebox, the faster andhotter the rate of burn; conversely, less air creates aslower burn. To fully open the primary air intake,move the handle as far as it will go to the left; movethe handle as far as it will go to the right, to close theprimary air control.

CHOOSING FIREWOOD
Your Heritage Wood Heater is designed to only burnfirewood-also known as cordwood.
CAUTION: DO NOT USE CHEMICALS OR
FLAMMABLE FLUIDS SUCH AS GASOLINE,
NAPHTHA, KEROSENE, CHARCOAL LIGHTER
FLUID OR ENGINE OIL TO START A FIRE. DO
NOT USE CHARCOAL, PELLETS, COAL,ARTIFICIAL LOGS OR ANY OTHER MATERIALSAS FUEL; THEY ARE NOT SAFE. DO NOT BURNGARBAGE.

The quality of your firewood affects heat output,
duration of burn and performance of your stove.
Softwoods generally burn hotter and faster, while
hardwoods burn longer and produce more long
lasting coals. Density and moisture content are two
critical factors to consider when purchasing wood foryour Fireplace Insert.
The following is a list of many common woodspecies and their relative BTU (British Thermal Unit)
content. The higher the BTU content the longer theburn. Firewood with higher a BTU content isgenerally considered ideal for a wood stove.

Moisture content plays a key role in the performanceof your stove. Wood freshly cut from a living tree
(green wood) contains a great deal of moisture. As
you might expect, green wood has difficulty burningand should be seasoned before using it in yourwood stove. To properly season green wood: split,
stack and allow to air dry for a period of one year.
Stack the firewood on skids or blocking to keep it off
the ground, cover only the top of the stack. Plastic

or tarps that cover the sides of the stack of woodtrap moisture and prevent the wood from drying. As
for stacking, an old Vermonter said, "The spaces
between the logs should be large enough for amouse to get through, but not for the cat that'schasing it."
DO NOT STORE FIREWOOD WITHINSTOVE’S
SPECIFIED
CLEARANCESCOMBUSTIBLE MATERIALS.

Do not throw wood into the stove.
Do not use the doors as leverage to force wood
into the stove.
Do not load wood that is encrusted with ice intoa burning stove as the thermal shock can cause
damage.
Do not use a manufactured grate. Burn the fire
directly on the soapstone that lines the bottom of
the firebox.

THE
TO

BUILDING A FIRE
Once you understand the controls of your woodstove and have chosen the appropriate firewood,
you are ready to start a fire.

Breaking In Your Wood Stove
It is imperative that your stove is "broken in" slowly.
Soapstone requires "seasoning"; over-firing a new
stove may cause soapstone to crack or may
damage other stove parts.
Moisture in thesoapstone must be driven out slowly to minimize the“shock” to the stone of its first exposure to highfirebox temperatures. In addition, the asbestos-free
furnace cement must be cured slowly to ensure
adequate sealing and bonding.
When you light your first fires, the wood stove will
emit some smoke and fumes. This is normal “offgassing” of the paints and oils used whenmanufacturing the wood stove.
If you find it
necessary, open a few windows to vent your room.
The smoke and fumes will usually subside after 10
to 20 minutes of operation. The odor and smoke willend once the stove is “cured”.
The first fires may produce other odors from
impurities that exist in the area immediately
surrounding the stove. Some of these impurities can
be cleaning solvents, paint solvents, cigarettes,
smoke, pet hair, dust, adhesives, a new carpet, andnew textiles. These odors will dissipate over time.
You can alleviate these odors by opening a few
windows or otherwise creating additional ventilation
around your stove. If any odor persists, contact yourdealer or an authorized service technician.
If you adhere to the following break-in procedure, as
well as all other operating procedures in this manual,
the cast iron and soapstone components of yourstove will give you many years of trouble-free use.
With use, the color of the soapstone may change
and small fractures may appear on the surface ofthe stone. These changes will only add characterand distinction to your stove.

The bottom layer of soapstone in the firebox isintended to prevent thermal stress and should
remain in place in the fire box at all times.

Building A Break In Fire
1. Open the front or side door and place five or six
double sheets of tightly twisted newspaper in thecenter of the firebox. Arrange kindling in acrisscross pattern over the newspaper. Kindlingshould be approximately ten pieces, 1/2" (13mm) in diameter and 10" to 18" (254 mm to 457mm) long.
2. Fully open the primary air control by pushing thecontrol handle fully to the left, away from thefirebox.
3. Light the paper under the kindling. Close theside door and leave the front door slightly ajar
momentarily until the kindling has started to burnand draft begins to pull.
4. Close the door and allow the fire to burn. Keepboth the front and side doors closed while thestove is in use. Make sure the grate is in theclosed position and the ash drawer is tightly
closed.
5. KEEP A WATCHFUL EYE ON YOUR STOVE tomaintain a steady, low-heat fire. Your first fireshould make the stove warm but not hot to thetouch. At most, a few small chunks of woodshould be added to the fire to reach safe breakin temperatures.
6. Once the stove is warm but not hot to thetouch, close the primary air control by pushing it
fully to the right to allow the fire to die out
completely.
7. Let the stove return to room temperature.
Build and maintain your first fire and first fire eachseason thereafter as outlined above. Your patience
will be rewarded by a properly seasoned stove.

Avoid the following conditions that can cause thesoapstone or cast iron pieces to break:Hearthstone Quality Home Heating Products, Inc. ®

NOTE: Cool flue gas temperatures present
during the break-in procedure may cause rapid
creosote build up. The glass may also get dirty.
A good hot fire will clean it. We recommend avisual inspection (and cleaning if necessary) of
your stovepipe and chimney once the break-in
procedure is completed.

Heritage Model 8021

Page 20 of 30

moment then open the door completely. This
procedure will allow the firebox to clear of
smoke before the door is opened fully. Also,
reloading on a bed of hot, red coals reduces
smoking time and will bring fresh fuel up to ahigh temperature rapidly.

NORMAL OPERATION
If your stove is not used continuously or has notbeen used in quite some time, follow the break-in
procedure at least once to minimize the stress of a
hot fire on a cold stove before proceeding withnormal operation. We recommend one break-in fireat the start of each heating season.
Prior to loading the stove, ensure the ash grate andthe ash pan door are closed. If they are left open,
the stove will over-fire and be damaged.
Also, ensure you clear away the ashes around the“doghouse.” The doghouse is the slight bulge ofmetal, located in the front lower center of the firebox.
If the front door is open, the doghouse is in the lower
center of the door opening. There is a hole locatedon the opposite side, which directs primary air into
the coal bed area of the firebox. Obstructing thishole will hinder the operation of the stove. Along withthe glass’ air wash, the air flow is regulated via theprimary air control lever.

Building A Fire For Everyday Use
1. Open the front or side door and place five or six
double sheets of tightly twisted newspaper in thecenter of the firebox. Arrange kindling in acrisscross pattern over the newspaper. Kindlingshould be approximately ten pieces, 1/2" (13mm) in diameter and 10" to 18" (254 to 457 mm)long.
2. Fully open the primary air control by pushing itcompletely to the left, away from the firebox.
3. Light the paper under the kindling. Leave thefront door slightly ajar momentarily until thekindling has started to burn and draft begins topull.
4. Close the door and allow the fire to burn.
5. Once the kindling is burning, open the front orside door and add logs, small at first, to build thefire up. Make sure to keep the logs away fromthe glass in front in order for the air-washsystem to work properly. Otherwise, keep thedoors and ash drawer closed while the stove isin use.
6. Once the fire is burning well, use the primary aircontrol to regulate the desired rate of burn.
Pushing the handle to the left opens the
PRIMARY AIR CONTROL for a high rate of burnor pushing it to the right for a low rate of burn.
NOTE: When opening the front or side door
to reload or re-arrange logs, it is advisable toopen the door just a crack, pause for a

Burn Rate
HIGH BURN: Fully load the firebox with wood on a
bed of hot coals or on an actively flaming fire andfully open the primary air control by moving it fully tothe left, away from the firebox. This will fully open
the primary air shutter.
A high burn rate isrecommended once or twice a day to fully heat thestovepipe and chimney, which will help minimize
creosote accumulation. Sustained top, center stonetemperature should not exceed 600° Fahrenheit(316C).
MEDIUM HIGH BURN: With the primary air control
in the closed position, move the control handle
slightly to the left.
MEDIUM LOW BURN: With the primary air control
in the closed position, move the handle half way
between the medium and low settings. A mediumlow burn rate should be the typical setting and ispreferable if the stove is to be left unattended.
LOW BURN: Close the primary air control bymoving it fully to the right. A low burn rate overextended periods of time is not advisable as it may
promote the accumulation of creosote. Inspect theventing system frequently if low burn rates aremaintained consistently.
NOTE: If equipped with the optional blower, thefollowing settings are recommended:
Low and Medium-Low Burn: Run the blower on low
for slower moving, but warmer air circulation. Turnthe knob ‘ON’, and then continue turning the control
knob clockwise until the blower is running at a low
speed.
Medium High and High Burn: Run the blower onhigh for maximum circulation. The blower speed is at
its highest setting when the control knob is firstturned to the “ON” position. Continue to turn thecontrol knob clockwise to reduce the blower speed if
desired. We recommended that you wait at least 30
minutes for the stove to warm up before running theblower.

Over-Fire Caution
Over-firing means the stove is operating attemperatures
above
the
recommended
temperatures outlined above in the BURN RATE
section. Over-firing should be carefully avoided

Hearthstone Quality Home Heating Products, Inc. ®

Heritage Model 8021

Page 21 of 30

since it will cause damage to the stove. Symptomsof over-firing include short burn times, a roaring
sound in the stove or stovepipe, and discoloration of
the stovepipe.
Over-firing can be caused by excessive draft,inappropriate fuel, and operator error. Correct anover-fire situation as follows:
EXCESSIVE DRAFT: Contact your dealer to have adraft reading taken. Any draft in excess of 0.1 wc
requires a damper in the stovepipe. Someinstallations may require more than one damper.
INAPPROPRIATE FUEL: Do not burn coal, kiln
dried lumber, wax logs or anything other than natural
cordwood.
OPERATOR ERROR: Make sure all the gaskets arein good condition. Replace worn out or compressedgaskets. Do not burn the stove with the front, side,ash door, as well as the ash grate in the open
position.
Monitoring the temperature of the surface of the topstones is the best way to determine if the stove isover-firing. If you suspect that your stove is overfiring, contact your dealer immediately. Damage
done by over-firing is not covered by yourwarranty. Results of over-firing can include: warped
or burned out internal parts, cracked stones,
discolored or warped external parts, and damaged
enamel.

Monitoring Stove Temperatures
Monitor the stove temperatures with a stove
thermometer (available from your dealer) placed on
the top center stone of the stove. The thermometer
could read as high as 500F (260C) on High Burnand 200-300F (93-149C) on low burn. Maintaining
sustained temperatures in excess of 600F (316C)
will cause the stones to crack and other damage tothe stove.
Do not over-fire the stove. (Refer to page 21).

REMOVAL AND DISPOSAL OF ASHES
Remove ashes when the stove is cold.
Use
protective fireplace gloves if the ash pan is warm.
Exercise extreme caution when handling, storing or
disposing of ashes.
The ash pan and ash pan access door are locatedunder the ash lip. The ash pan collects ash from afirebox and allows you to conveniently remove theash from your wood stove. Clear the firebox ofashes often, and do not allow them to build up morethan 3 inches high. It is especially important toprevent ashes from building up around the ‘doghouse’, or lower primary air inlet. Clear the firebox ofashes by sliding the ash grate towards the front door
(see page 18), sifting the ashes across the grate into
the ash pan, then returning the grate to its closed
position. The ash pan is easy to remove and has a
handle for convenient disposal of ashes. The back of
the ash pan assembly is sloped upwards. Before
removing the ash pan, push it (hard!) into the stove
to force the pan up the slope, which kicks the ashes
further into the pan.
Ashes should be dumped from the ash drawer into a
metal container with a tight fitting lid. Do not place
any other items or trash into the metal container.
Replace the lid onto the container and allow theashes to cool. Do not place the ash disposal
container on a combustible surface or vinyl flooring,as the container will be hot!
Pending disposal, place the closed ash container on
a noncombustible floor or on the ground, well awayfrom all combustible materials. Ashes should be
retained in the closed container until all cinders havethoroughly cooled.
Ashes should NEVER be placed in wooden or
plastic containers, or in paper or plastic bags, nomatter how long the fire has been out. Coals within
a bed of ashes can remain hot for several days once
removedfromthefirebox.

NOTE: ANY SYMPTOMS OF OVER-FIRING
WILL VOID YOUR WARRANTY!!

Maintenance
CREOSOTE FORMATION AND NEED FORREMOVAL
When wood is burned slowly, it produces tar andother organic vapors, which combine with expelled
moisture to form creosote. These creosote vapors
condense in the relatively cool chimney flue of aslow-burning fire. As a result, creosote residue
accumulates on the flue lining. When ignited, thiscreosote makes an extremely hot fire, which may
damage the chimney or even destroy the house.
The chimney connector and chimney should be
inspected at least once every two months during theheating season to determine if a creosote buildup
has occurred.
To prevent the buildup of creosote:1.

2.

Burn the stove with the primary air control fully
open for 35 - 45 minutes daily to burn out
creosote deposits from within the stove and theventing system.
After reloading with wood, burn the stove withthe primary air control fully open for 20 to 30
minutes. This manner of operation ensures
early engagement of the secondary combustion
system which, when engaged, minimizes
creosote buildup in the chimney.

If a creosote residue greater that 1/4" (6 mm) has
accumulated, it should be removed to reduce therisk of a chimney fire.
If your glass remains dirty, your operating
temperatures are low; therefore, there is a higher
risk of creosote buildup.
The venting system must be inspected at the stoveconnection and at the chimney’s top.
Coolersurfaces tend to build creosote deposits more
quickly, so it is important to check the chimney at the
top (where it is coolest) as well as from the bottom
near the stove.
Accumulated creosote should be removed with acleaning brush specifically designed for the type ofchimney in use. A certified chimney sweep should
be used to perform this service. Contact your dealer
for the name of a certified chimney sweep in yourarea (your dealer may be a certified sweep!).
We recommended you have the entire systemprofessionally inspected before each heating
season, and cleaned and repaired, if necessary.

GASKETS
Gasket material should normally be replaced every
two to three seasons, depending on stove use. If
the door seal is loose, a new gasket will assure atight seal and improved stove performance. Contact
your dealer for a gasket kit (PN 90-58210) that
includes instructions and gaskets for your stove.
The procedure for replacing gaskets on the glass isreviewed on page 24.
To replace door gaskets, first remove the oldgaskets with a utility or putty knife. Clean all gasket
channels with a wire brush. Apply gasket cement tothe channels and push the new gasket into place
without stretching the gasket material. The door
should be shut immediately to fully press the gasket
into place and assure a positive seal.
We require the use of the following gaskets (in kit
90-58210):
DOOR: 67" (170 cm) Length, 3/8" (9.5 mm)
Diameter, Adhesive Black TubeGLASS: 58" (140 cm) Length, 1/4" (.64 cm)
Diameter, Low Density Black Tube
ASH DOOR: 35" (89 cm) Length, 3/8" (9.5 mm)
Diameter, Low Density, Black Tube
SIDE DOOR: 46" (117 cm) Length, 3/8" (9.5mm) Diameter, Low Density, Black Tube

GLASS
Do not operate the stove with a broken door glass.
Do not abuse the front door by striking or slamming.
Important: scratching or etching the glass
will weaken the integrity of the glass. Do not
use a razor blade, steel wool, or any otherabrasive material to clean the glass. Use low
alkaline content cleaners only.
The front door glass is a ceramic, shock-resistantglass, made specifically for use in woodstoves. Do
not use any replacement glass other than theceramic glass manufactured and supplied for use inthis woodstove. Replacement glass is available
through your local dealer.
The door glass should be replaced immediately if
broken or chipped. Contact your local dealer for a
replacement glass kit (PN 90-58215), which isaccompanied with instructions and everything

6. Place the gasketed glass onto the door. Place a
new clips and gasket squares around the glass,and over the screw holes in the clip.
7. Screw the glass retainer clips (8) back on thedoor.
8. Install the door.

Glass Cleaning
When necessary, clean the glass with low alkalinecontent commercial stove glass cleaners, which areavailable from your local dealer. Never attempt toclean the glass while the fire is burning or the glass
is hot. Most deposits can be cleaned by following
the instructions provided with the cleaner.
To clean heavier deposits, open the door and lift itstraight up and off the stove with the hinge pins
remaining in the door (take care to save hinge pins
and washers for reuse). Lay the door face down on
a workbench or table, with the handle hanging off anedge so it will lie flat. Apply the cleaner to the glass
and allow it to soak for a few minutes.
By laying the door flat, it will allow the cleaner topenetrate rather than run off the surface of the glass.
Wipe the cleaner off with a soft cloth, or plain black& white newsprint.

STONE
Occasional cleaning is all that should be necessary
to maintain the natural beauty of your stove’s
polished soapstone finish. Clean the soapstone withwater, any non-abrasive cleaner and a soft cloth.
Wipe dust from the stone with a clean cloth. Do notuse chemical agents to wash the stone; do not use
waxes or any polishing agents on the stone.

Figure 15 – Door and Glass Components Detail
Take care to not scratch or chip the stone. Do not
set items, which can stain, scratch or chip the stone(or enamel finish), on top of your stove.
Often, with use and over time, subtle earth tones ofbrown, red, and yellow appear on the soapstone.
This is a natural reaction in the soapstone. Surface
or hairline fractures may appear in the stone after astove has been used. Such changes are normal anddo not affect the operation or the integrity of thestove and do not require replacement. If you
observe a completely broken stone, contact yourdealer for service.

sponge to wipe clean. Dry the cast iron thoroughly
to prevent rusting.

CAST IRON
Exterior cast iron parts are either painted with black,high-temperature stove paint or porcelainized withan enamel finish in various colors.
Use black, high-temperature stove paint (satin blackby Stovebright) to touch up and maintain the original
appearance of painted cast iron. Use a damp

Enamel castings can be cleaned with a standard
glass cleaner. With time and use, a very fine, subtle
network of crazing (tiny lines) may appear seemingly
beneath the surface of the enamel. Crazing is anatural predictable process and does not represent
a flaw.

Troubleshooting
Virtually all woodstove operators experience basic
common problems at one time or another. Most are
correctable and generally require only a minor
adjustment of the stove, installation, or operating
technique.
In cases where weather conditions
dramatically affect stove performance, the problems
are typically temporary and solve themselves once
the weather changes.
If you question whether your stove is producing
adequate heat, the best way to troubleshoot the
problem is to monitor the temperature of the stack. A
400 degree F (200 degree C) stovepipe confirms thestove is supplying sufficient heat. Keep in mind thatyour house itself will regulate room/housetemperatures. How well the walls, floors and ceilings
are insulated, the number and size of glass windows,
the tightness of outside doors, and the construction
or style of your house (vaulted ceilings or other open
spaces which collect large percentages of heat,ceiling fans, etc.) all are determining factors of room
temperature.
Your stove's performance is also dependant on its
installation.
One common cause of poor
performance is an oversized chimney flue.
Oversized chimney flues result in decreased draft,which prevents the smoke from rising out thechimney. Oversized flues are also more difficult toheat effectively, especially when burning a highefficiency stove. Cool flue temperatures inhibit theestablishment of a strong draft (and encourage theaccumulation of creosote). The lack of a strong draft
will cause the fire to die down and may even force
the smoke to pour into the room.
If your chimney is the proper size and a strong draft
is not easily established, there is the possibility of thechimney being too cold.
Again, hot chimneys
promote a stronger draft.
Other draft guidelines are as follows:
AN "AIRTIGHT" HOUSE: If your home is superinsulated or especially well sealed, the (infiltration) air
supply to the interior of the house may beinadequate. This phenomenon of air starvation within

the building can be exacerbated if exhaust fans, suchas clothes dryers, bathroom fans or cookstove
exhaust fans, are in operation within the home.
Outfitting your stove with the optional outside air
supply adaptor connected to an air duct which leads
to the outside of the building should correct thisproblem.
TALL TREES OR BUILDINGS: These obstructions,when located in proximity to the top of the chimney
can cause chronic or occasional downdrafts. Whenselecting a site for a new chimney, take care toconsider the placement of other objects near the
proposed chimney location.
WIND VELOCITY: Generally, the stronger andsteadier a wind, the stronger (better) the draft.
However, "gusty" wind conditions may cause erratic
downdrafts.
BAROMETRIC PRESSURE: Chimney drafts are
typically sluggish on balmy, wet or muggy days. Thisis a weather-related phenomenon, which generally is
self-correcting as the weather changes.
BRISKNESS OF FIRE: The hotter the fire in yourstove, the hotter your chimney and, therefore, thestronger the draft.
BREAKS IN THE VENTING SYSTEM: An unsealed
clean-out door at the bottom of the chimney, leaky
stovepipe joints, a poor stovepipe-to-thimble
connection, missing caps, or a leaky chimney may
cause inadequate draft.
SEASONAL FACTORS: Early fall and late spring are
generally difficult seasons in which to establish
proper drafts. The colder the outside air is (relative toroom temperatures) the stronger the draft.
Operating the Stove:
There are days when a draft is not easily established.
As outlined above, seasonal factors or a coldchimney may be the cause. Try starting the fire byusing small kindling and fuel to obtain a quick, hotfire. Tend the fire frequently with small fuel until thechimney is hot and the draft is well established.
