Introducing Your
Craftsbury Wood Stove
Welcome to the HearthStone family.
You have made an investment in one of the
finest solid fuel heaters available today. To own
a HearthStone is to make a statement – a
statement that you appreciate exceptional
quality and efficiency in a stove that is backed
by the best warranty in the hearth industry.
Your purchase insures you of 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 equipped stove. The Craftsbury blends
modern technology with the time tested beauty
of matte or enameled cast iron. We trust that
you will appreciate the value 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. At the same time, keep it as close to
the chimney as possible. Review the proper
clearance measurements from combustible
surfaces. You can safely reduce required
clearances in most cases with the rear heat
shield that the stove was tested with and close
clearance pipe, or by following the NFPA 211
codes. Consult with your local authorities
having jurisdiction.
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 liquids are used or stored.
The walls of a Hearthstone stove produce both
radiant and convective heat. Locate the stove
centrally in your living area to allow the heat to
travel naturally to distant rooms. To heat the
maximum area, do not locate your stove in an
uninsulated basement. The amount of energy
required to heat the concrete basement walls is
so great that most of the usable heat will be
absorbed by the walls 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

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 Month:
• Visually inspect chimney connector and
chimney for creosote; clean accordingly.
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. (Refer to page 23 – Creosote
Formation and Need For Removal)
• 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
24 – Gaskets)
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 inspected for any
sign of damage. You must correct any damage
before using your stove again.
CAUTION:
The ceramic baffle inside the firebox is not
packing and should not be removed from the
stove prior to lighting (see below).
HearthStone’s Thermo-Ceramic Baffle System

Setting Up Your
Craftsbury Wood Stove
UNPACKING
Your Craftsbury stove is packaged with the
great care, so that it ships safely. Under certain
circumstances, however, damage can occur
during transit 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 be
placed. 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,
furniture, and curtains. 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.
The area under and directly in front of the stove
need to be protected as described on page 10.
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.
Read this entire section to obtain a sound
understanding of how to properly install your
stove.
If you use a close clearance connector pipe, it
must be tested and listed to UL standards.
Check the listing for 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
following the tested methods (rear shield and
close clearance connector pipe) or by
following the criteria specified in NFPA 211
for US and CAN/ULC B 365 for Canada.
.
CLEARANCES TO NFPA 211
PROTECTED SURFACES
You can reduce the clearances to
combustible surfaces by using any National
Fire Protection Agency (NFPA) approved
wall protection system. Please refer to
NFPA 211 (US) and CAN/ULC B 365 (Can)
for specifications and complete details. You
can obtain this information directly from
NFPA or CSA.

FLOOR PROTECTION
Install your stove on one of the following:
 Noncombustible floor protector underneath
the stove that extends 16 inches (US) / 46
cm (Can) beyond the front door and 8 inches
US / 203 mm (Can) beyond each side of the
fuel loading and ash removal opening.
 A commercially manufactured hearth that is
tested and listed to UL 1618 can be used as
the floor protection if it meets the minimum
size requirement (38.5” by 41”) US and
(98cm by 109 cm) Can.
• For horizontal chimney connector
installations, the floor protection must be
installed beneath the connector and 2”
beyond each side.
AND STOVE TO EDGE CLEARANCES
MINIMUM FLOOR PROTECTOR SIZE
OUTSIDE AIR SUPPLY
An outside air source may be connected
directly to this stove using an optional outside
air kit (HearthStone part #90-53210). 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 where the house or other
appliances may compete for the combustion air.
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 termination of the
duct on the outside wall of the house 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.
When using the optional outside air kit, a gate
valve must be installed.

DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE
• 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 and may also be used
with a masonry chimney to reduce
clearances, is available from several
manufacturers, your dealer can help you
choose. Some manufacturers of close
clearance connector pipe are Simpson Dura
Vent, Metalbestos, Security, GSW and
Ameritec.
• When used in a mobile home, a spark arrester
venting cap is 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 shall conform 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 FROM THE
MANUFACTURER OF YOUR
CONNECTOR. USE OF MAKESHIFT
VENTING COMPONENTS MAY
COMPROMISE THE SAFTY OF THE
INSTALLATION.
-------------------------------------------------------------------------------------------------------------------------------------------------------
VENTING CONFIGURATION
COMPONENTS OF A VENTING SYSTEM
The complete venting system will consist of
several components: chimney connector, wall
thimble, wall pass-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 the venting system. Upon inspection,
immediately replace rusted, cracked, or broken
components.
• The chimney connector is the stovepipe
from the woodstove 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 the extreme temperatures
of a wood fire.
• A thimble is a manufactured (or site-
constructed) device installed in combustible
walls through which the chimney connector
passes to the chimney. It keeps the walls
from igniting. You must use a wall thimble
when installing a chimney connector
through a combustible wall to the 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
prefabricated residential type building
heating appliance chimney. Do not connect
this stove to a chimney serving another
appliance; you will compromise the safe

HearthStone Quality Home Heating Products Inc ®Model 8390
13
operation of both the wood stove and the
connected appliance.
▌WARNING:
DO NOT CONNECT THIS APPLIANCE TO ANY
AIR DISTRIBUTION DUCT OR SYSTEM.
• A liner (listed to UL 1777 or ULC S635)
creates an acceptable flue in a factory built
fireplace or in an existing 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 the stove to a proper chimney.
INSTALLING A VENTING SYSTEM
Stovepipe sections must be attached to the stove
and to 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 to the 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. Failure to install the
screws can cause joints to separate from the
intense vibration that results 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 the
stovepipe (without moving the stove) when you
periodically inspection or clean the stovepipe
connection and chimney.
Install the stove as close as practical to the
chimney, 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 of stovepipe or more connecting elbows
than necessary increase the chances of draft
resistance and the accumulation of creosote
buildup.
In general, you do not need to install a stovepipe
damper with the Craftsbury. 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 can help regulate the draft. The
Craftsbury requires a draft between 0.06" wc
and 0.1" wc. For drafts above 0.1" wc, install a
stovepipe damper.
Remember, the NFPA has recommended,
minimum clearances for chimney connectors to
combustibles such as walls and ceilings. Once
the stove is installed 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 Craftsbury to a
prefabricated metal chimney or a masonry
chimney.
CONNECTING TO A PREFABRICATED
METAL CHIMNEY
When connecting the Craftsbury to a
prefabricated metal chimney, you must follow,
precisely, the manufacturer's installation
instructions. Use only Type HT (2100 deg. F),
prefabricated metal chimneys listed per UL 103
or ULC S629 standards.

HearthStone Quality Home Heating Products Inc ®Model 8390
14
▌WARNING:
DO NOT CONNECT THE STOVE TO A
CHIMNEY FLUE SERVING ANOTHER
APPLIANCE.
Make sure the size of the chimney’s flue is
appropriate for the Craftsbury. The Craftsbury
requires a 6" (152 mm) inside diameter flue for
new installations. A 6” diameter flue provides
adequate draft and performance. You can use
an 8" (203 mm) diameter existing interior flue
with a reducer. An oversized flue, especially a
cold, exterior flue, contributes to draft reduction
and creosote accumulation. (In this case, bigger
is NOT better.)
When purchasing a prefabricated chimney to
install with your stove, be sure to also purchase
from the same manufacturer all of the necessary
components such as the wall pass-through (or
ceiling support 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 installing the chimney and
accessories. In addition, be sure to maintain all
manufacturers’ recommendations for the proper
clearances to the chimney.
Reversing the flue collar
The Craftsbury can be vented either horizontally
or vertically by reversing the flue collar.

There are basically two ways to install a
prefabricated metal chimney:
• An interior installation where the chimney
passes inside the residence through the
ceiling and roof.
• An exterior installation where the chimney
passes through the wall behind the stove
then up the outside of the residence.

Whenever possible, choose an interior chimney.
An interior chimney heats up more quickly and
retains its heat; thus promotes a better draft and
discourages the formation of creosote. An
exterior chimney does not benefit from the
warmth of being surrounded by the building, so
it typically operates at lower flue temperatures
than an interior chimney. An exterior
chimney’s draft is not as strong and may
experience increased creosote accumulation.

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 the chimney. Use only
Code approved masonry chimneys 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
and blockage. If the chimney needs repair,
complete them before installing and using your
stove. Do not install your stove until the
chimney is safe for use.
Make sure the chimney’s cleanout is complete
and working properly. To avoid a loss of draft,
the cleanout must close off completely. If
allowed to cool, your stove will perform poorly
and creosote will build up in the chimney.
Make sure the size of the chimney’s flue is
appropriate for this stove and that it is not too
large. Use a masonry chimney with an 8" x 8"
(203 mm x 203 mm) tile size for best results.
An oversized flue will contribute to the
accumulation of creosote.
Use the following checklist to ensure that your
masonry chimney meets these minimum
requirements:
Chimney wall construction:
 Brick or modular block at least 4" (102 mm)
thick.
 A rubble or stone wall at least 12" (305 mm)
thick.
Flue liner:
 Minimum thickness of 5/8" (16 mm).
 Installed with refractory mortar.
 At least 1" (25 mm) air space.
 An equivalent flue liner must be a listed
chimney liner system meeting type HT
requirements or other approved material.
Interior chimney requirements:
 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.
Exterior chimney requirements:
 At least 1" (25 mm) clearance to
combustible structure.
Chimney height requirements: (See Illustration)
 At least 3 feet (0.9 m) higher than the
highest part of the roof opening through
which it passes.
 At least 2 feet (0.6 m) higher than any part
of the roof within 10 feet (3 m) measured
horizontally from the top of the chimney.
This stove requires a minimum chimney height
of 13 feet (4 m). The maximum allowable
chimney height is 30 feet (9m).

Operating Your
Craftsbury Wood Stove
Once your Craftsbury has been set in place,
connected, and assembled, you are ready to light
a fire. HearthStone Stoves tests each wood
stove before we ship, so you should be able to
easily light your first fire. You may, however,
have to make a few small adjustments to
compensate for altitude and other factors
particular to your installation.
▌WARNING:
HOT WHILE IN OPERATION. KEEP
CHILDREN, CLOTHING AND
FURNITURE AWAY. CONTACT MAY
CAUSE SKIN BURNS.
Please read this entire chapter before lighting
your first fire. It explains the controls and
features of your wood stove, how to choose
firewood, and how to break-in your stove and
use it on a daily basis.
CONTROLS AND FEATURES
Before lighting any fires, become familiar with
the location and operation of your stove's
controls and features 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. To
open the door, lift the handle to the 10 o’clock
position and pull the door. To latch the door
lower the handle to the 7 o’clock position. Pull
on the door to make sure it is properly latched.
The wooden handle can be removed or left in
place.
PRIMARY AIR CONTROL: This feature is
located on the lower left front of the stove,
under the ash lip. The primary air control
allows you to regulate the amount of air entering
the firebox. Generally speaking, the more air
allowed into the firebox, the faster and hotter
the rate of burn; conversely, less air creates a
slower burn. Pull the lever out, away from the
ash lip to open the primary air control; push the
lever in under the ash lip of the stove to close
the primary air control.
ASH PAN DOOR & ASH PAN: Open the ash
pan door by lifting up on the handle bar and
allowing the door to fall into the open position.
The ash pan tray can now be easily removed by
carefully pulling it straight out, use fireplace
gloves if hot ashes or coals are present. You can
now empty ashes that have been sifted into the
tray through the grate in the firebox. After you
have properly emptied the ashes into a covered,
noncombustible container, push the ash pan all
the way into the stove and close the ash door by
lifting it up and locking it in place by pulling
down on the handle bar.
Do not operate the stove unless the ASH
PAN DOOR is tightly closed. This could
cause the stove to overheat and damage
the components of the stove.
It is best to remove ashes when the stove is cold.
If the ash pan is warm, use protective fireplace
gloves. Exercise extreme caution when
handling, storing or disposing of ashes.

CHOOSING FIREWOOD
Your Craftsbury Wood Heater is designed to
only burn firewood-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 MATERIALS AS FUEL; THEY
ARE NOT SAFE. DO NOT BURN
GARBAGE.
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
coals. Density and moisture content are two
critical factors to consider when purchasing
wood for your stove.
The following is a list of wood species and their
relative BTU (British Thermal Unit) content.
The higher the BTU the longer the burn.
Firewood with higher BTUs is generally
considered more ideal for a wood stove.
HIGH: Apple, Black Birch, Hickory, Locust,
White Oak, Black Beech, Mesquite
MEDIUM HIGH: White Ash, Beech, Yellow
Birch, Sugar Maple, Red Oak
MEDIUM LOW: Black Ash, White Birch, Grey
Birch, Elm, Norway Pine, Pitch Pine, Black
Cherry, Soft Maple, Tamarack
LOW: White Pine, White Cedar, Balsam Fir,
Spruce, Aspen, Basswood, Butternut, Hemlock
Moisture content also plays a key role in the
performance of 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 burning and should be
seasoned before using it in your wood stove. To
properly season green wood, it should be split,
stacked and allowed to air dry for a period of
one year.
Stack the firewood on skids or blocks to keep it
off the ground, cover only the top of the stack.
Plastic or tarps that cover the sides of the
woodpile trap moisture and prevent the wood
from drying. As for stacking, an old Vermonter
said, "The spaces between the logs should be
large enough for a mouse to get through, but not
for the cat that's chasing it."
Firewood should not be stored within the stove's
specified clearances to combustible materials.

BUILDING A FIRE
Once you understand the controls of your wood
stove and have chosen the appropriate firewood,
you are ready to start a fire.
BREAKING IN YOUR WOOD STOVE
It is imperative that your stove be "broken in"
slowly. Cast iron must be "seasoned"; over-
firing a new stove may cause castings to crack
or may damage other stove parts.
The soapstone on the back and bottom in your
firebox is intended to prevent thermal stress;
leave it in place in the firebox at all times.
When you light your first fires, the wood stove
will emit some smoke and fumes. This is
normal “off-gassing” of the paints and oils used
when manufacturing 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 will end once the stove is
“cured”.
BUILDING A BREAK IN FIRE
1. Open the door and place five or six
double sheets of tightly twisted
newspaper in the center of the firebox.
Arrange kindling in a crisscross pattern
over the newspaper. Kindling should
consist of about ten pieces of very dry
wood split to approximately 1/2" (13
mm) in diameter by roughly 10" (254
mm) long.
2. Fully open the primary air control by
pulling the lever fully out, towards you.
3. Light the paper under the kindling.
Leave the door slightly ajar momentarily
until the kindling has started to burn and
draft begins to pull.
4. Close the door and allow the fire to burn.
Keep the front door and ash pan door
closed while the stove is in use. Make
sure the grate is in the closed position.
5. KEEP A WATCHFUL EYE ON YOUR
STOVE to maintain a steady, low-heat
fire. Your first and subsequent break-in
fires should make the stove warm but
not hot to the touch. At most, a few
small chunks of split cordwood should
be added to the fire to reach safe break-
in temperatures.
6. Once the stove is warm but not hot to
the touch, close the primary air control
and allow the fire to die out completely.
7. Let the stove return to room temperature.
Your first three break-in fires should be built
and maintained as outlined here. Your patience
will be rewarded with a properly seasoned
stove.
NOTE: Because of the cool flue gas
temperatures present during the break-in
procedure, creosote may build up quickly. We
recommend a visual inspection (and cleaning if
necessary) of your stovepipe and chimney once
the break-in procedure is completed.
