Introducing Your

Heritage Wood S tove

Congratulations! You have just invested in a most unique
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 wood burning stove. At 2.2 cubic
feet capacity and 2.6 grams per hour particulate you can
be proud to join the HearthStone family with our Premier
Soap Stone 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 insures years of clean, comfortable heat
with minimal maintenance. You will receive the benefits
of the most advanced technology in wood burning without
the cost and maintenance requirements of a catalytic
stove. The Heritage blends modern technol ogy wi t h the
unique beauty and heating qualities of soapstone, long
known for its even heat production and long heat­retaining 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 and maintenance. 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, and local
building codes to install your stove. Be sure to maintain
the designated stovepipe and stove clearances to walls,
ceilings, hearth, and other combustible surfaces. This will
help reduce the risk of fire. Failure to follow these
instructions can result in property damage, bodily injury,
and even death.

Locate your stove in a safe, convenient, open area; away
from traffic flow, doors, and hallways; and near a
chimney and chimney connector. Review the proper
clearance measurements from combustible surfaces. You
can safely reduce required clearances in most cases by
using the, optional, rear heat shield, and also with a
special connector pipe and special wall coverings as
specified by this manual, the NFPA 211 codes, and your
local authorities having jurisdiction.

HearthStone Quality Home Heating Products Inc ® Heritage Model 8021

Keep furniture, drapes, curtains, wood, paper, and other
combustibles far away from the stove. Never install the
stove in a location where gasoline, kerosene, charcoal
lighter fluid or other flammable liqui d s 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 radiant energy required to heat
concrete basement walls is so great that most of the usable
heat is absorbed by them and lost.

SAFETY NOTICE:

A HOUSE FIRE MAY RESULT IF THIS
STOVE IS NOT INSTALLED PROPERLY.
FOR YOUR SAFETY, CAREFULLY
FOLLOW THE INSTALLATION
DIRECTIONS. CONTACT LOCAL
BUILDING OR FIRE OFFICIALS ABOUT
RESTRICTIONS AND INSTALLATION
INSPECTION IN YOUR AREA.

The performance of your stove depends on many
variables. Since all installations are unique, the general
information and operating procedures presen t ed he re can
only serve as useful guidelines rather than hard and fast
rules. Should you have any questions, do not hesitate to
contact your dealer for additional information.

Validate your warranty - return your warranty registration
card to HearthStone within 30 days of purchase. Once
your warranty has been validated by returning your
warranty card, contact your dealer for any necessary
warranty service.

SAFETY INFORMATION

Read and understand this Owner's Manual
thoroughly before installing and using this stove.

Make sure to install your stove:

 According to the manufacturer's recommendations.

 In accordance with all applicable codes.

 With the proper sized chimney.

When using your stove:

 Warn children and others unfamiliar with woodstoves

of the danger of touching hot, radiati n g s ur faces of
your stove. For your additional 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 and

lower 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.

 Keep the ash pan tray fully inserted and the ash door

closed tightly.

 Inspect the stovepipe, chimney connector and

chimney, as recommended.

Follow these safety precautions:

 Never modify this stove in any way, especially the

primary air control system.

 Never burn kiln dried wood, painted or treated wood,

solvents, trash, plywood, colored or glossy paper,
artificial logs, cardboard, coal, garbage or driftwood.

Especially, do not burn coal 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. Keep all 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 to elevate the

fire.

 Do Not allow logs to rest against or otherwise come

in contact with the glass when the door is closed.

 Do Not slam the door or use the door to force wood

in to the stove.

 Never over-fire your stove. (See page 18)

 Never put articles of clothing or candles on a hot

stove.

 Do Not connect the stove to a flue that is serving

another appliance.

Other safety guidelines

 Keep all combustible items such as furniture, drapes,

clothing, and other items, at least 36" (0.92 m) from
the stove (See page 8)

 Install a smoke detector, preferably in an area away

from your wood stove.

 Keep a fire extinguisher handy. We recommend the

type rated "A B C."

 Dispose of ashes properly. (See page 18)

 Keep children and pets away from the stove; they

could be burned by touching a hot stove.

 Clean your chimney system as needed. (See page 19)

HearthStone Quality Home Heating Products Inc ® Heritage Model 8021

PERIODIC CHECKLIST

Perform 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 fill up.

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. (Please see page 19)

• Check door seals using the "dollar bill test." - When
the fire is out and the stove is cool, shut the 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 19.)

At the End of Every Season:

• Dismantle the chimney connector and clean it
thoroughly. Replace any pieces that show signs of
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 if worn,

frayed, cracked or extremely hard.

EMERGENCY PROCEDURES

If you have a stovepipe or chimney fire, follow these
instructions:

1. If the fire is too threatening, leave the area and call
the fire department immediately! If not, perform the
next three steps.

2. Close the primary air control.

3. Close the stovepipe damper (if present).

4. Keep the stove front, side and ash doors closed!

▌ WARNING

DO NOT ATTEMPT TO PUT OUT A STOVEPIPE
OR CHIMNEY FIRE BY THROWING WATER
ONTO THE STOVE, STOVEPIPE, OR
CHIMNEY. THE EXTREMELY HIGH
TEMPERATURE ASSOCIATED WITH SUCH
FIRES CAN CAUSE INSTANTANEOUS STEAM
AND SERIOUS BODILY HARM.

Once the chimney fire has expired, leave the primary air
control closed and let the fire in the stove die out
completely. The stove should not be fired again until the
stove, stovepipe, and chimney are all thoroughly

UNPACKING

HearthStone Stoves packages your Heritage stove with
the greatest care, so that it ships safely. Under certain
circumstances, however, damage can occur during tra nsit
and handling. When you receive your stove, unpack it
carefully, inspecting your stove and all parts for damage.
Also, make sure that all parts are included in the box. If
any parts are damaged or missing, please contact your
dealer immediately.

INSTALLING YOUR STOVE

First, you must decide where your stove will reside. After
choosing an appropriate spot, inspect this location to
make sure that the stove will have enough clearance to
combustible materials that would surround the stove.
These combustibles can include walls, floor, ceiling,
fireplace, and chimney. You must carefully consider the
clearances to all of these combustibles before actually
connecting your stove. When considering these
clearances, also decide the kind of floor the stove will rest
on. Unless it is being installed on non-combustible
flooring, a floor protector with an R-value of 1.2 is
required.

Please use this section to plan how to locate your stove in
your particular location. Consider both the clearances of
the stovepipe and the stove itself to the surrounding
combustibles. Also consider access to the side door.

The soapstone walls of the Heritage soapstone stove
produce and even, radiant heat. Locate the stove centrally
in your living area to allow the heat to travel naturally to
distant rooms. It is not recommended that you locate your
stove in an uninsulated basement. The amount of radiant
energy required to heat concrete basement walls is so
great that most of the usable heat is absorbed by them and
lost.

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

If you use a close clearance connector pipe, it must be
tested to UL standards and listed. Check the listing of
your

pipe for actual clearances. The diagrams in this
manual represent typical installations, but are specific to
the Simpson Dura-Vent DVL brand. Clearances cannot
be reduced without the use of close clearance connector
pipe and/or by protecting the surfaces per NFPA 211
standards.

HearthStone Quality Home Heating Products Inc ® Heritage Model 8021

Clearances To NFPA 211 Protected Surfaces

You can reduce the clearances to combustible surfaces by
using any National Fire Protection Agency (NFP A)
approved wall protection system. Please refer to NFPA
211 for specifications and complete details. You can
obtain this information directly from NFPA.

HEARTH REQUIREMENTS AND FLOOR
PROTECTION

Combustible flooring must be protected with a covering
of noncombustible material with an R-value of 1.2 (slate,
marble tiles, or other noncombustible material can be
used for this purpose). The floor protection must extend
beyond the body of the stove at the minimum as follows:

• LEFT SIDE 16” (40.64 cm)*

• RIGHT SIDE 8” (20.32 cm)

• REAR 2” (5.08 cm)**

• FRONT 16” (40.64 cm)*

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—no
conversion 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

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 than the
R-value of the specified floor protector, then your setup is
acceptable.

Handle Assembly

Locate the handle, bolt, and washers enclosed in the
envelope with the owner’s manual. Place the washers on
the bolt and then push it through the handle so that the
bolt threads extend through the bottom of the handle.
Using a slotted screwdriver, turn the bolt into the chrome
latch on the door, until snug.

Handle Operation

Front Door – when closed, the handle will be in the 7
o’clock position. To open the front door, rotate the latch
clockwise to approximately the 10 o’clock position.

Ash Pan Door – when closed, the handle will be in the 7
o’clock position. To open the ash door, rotate the latch
counter-clockwise to approximately the 6’clock position.

Side Door – when closed, the handle will be in the 5
o’clock position. To open the side door, rotate the latch
counter-clockwise, to approximately the 2 o’clock
position.

UTSIDE AIR SUPPLY

O

(Kit #90-53210)

An outside air source may be connected directly to this
stove using an optional outside air kit. The advantage of
providing outside air directly to the stove is that the air
used by the stove for combustion is taken from outside of
the residence rather than from 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 airtight
house.

The outside air kit for this stove allows for the direct
connection of the stove's air intake to a minimum 3" (76
mm) diameter duct (supplied by others) which leads to the
outside of the house. When considering placement of the
duct from the outside of the house to the hearth, keep in
mind the need to avoid structural members of the house.
The outside air kit will attach to the back of the stove.

The termination of the duct on the outside wall of the
stove should be located in such a manner so as to preclude
the possibility of obstruction by snow, leaves or other
material and should be screened against animals and
insects. The termination should be screened using
¼” x ¼” mesh rodent screen and be covered with a
rain/wind proof hood (flex pipe, outside termination,
mesh, and hood supplied by others) Contact your dealer

for availability).
