Warning
During the break-in fires (see page 18), you do not heat the stove to high
temperatures as you would once the stove is seasoned. Due to this, you
may notice a small amount of black liquid dripping from the bottom of the
stove. This is from incomplete combustion of the wood and from
condensation within the stove. This dripping liquid will only last for the
first couple of fires. After this the dripping will stop. You may want to
place a noncombustible material under the stove to protect your hearth
from stains until your break-in fires are complete.

Introduction
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 ensures 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 is 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 is 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
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

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. Once you have a
registered warranty, contact your dealer for any
necessary warranty service.

PERIODIC CHECKLIST
PLEASE EXERCISE CARE WHEN LOADING
WOOD OR CLEANING YOUR STOVE, NOT TO
DAMAGE THE Thermo-Ceramic BAFFLE
Perform each of these tasks at the specified
intervals.
Located directly above the burner tubes in the
firebox, this white sheet of material will break if wood
or cleaning brushes impact it. Be careful when
loading and cleaning your stove to not break this
material. If this piece has been fractured or a hole is
punctured, it will cause the stove to function
improperly. You must replace the board through a
qualified Hearthstone dealer.
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 21 – Creosote Formation and Need For
Removal)
EMERGENCY PROCEDURES
If you have a stovepipe or chimney fire, follow
these instructions:
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 21 –
Gaskets)
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!
At the End of Every Season:
Dismantle the chimney connector and clean it
thoroughly. Replace any pieces that show signs
of rust or deterioration.
▌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.
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.
CAUTION:
The ceramic baffle inside the firebox is not
packing material! Do not remove it from the
stove prior to lighting.
Once the chimney fire has expired, leave the
primary air control closed and let the fire in the
stove die out completely. Do not fire the stove
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.
Hearthstone’s Thermo-Ceramic
Baffle System
To enhance the combustion efficiency and reduce
the emissions of the fire in your stove HearthStone
QHHP, Inc. has developed an advanced THERMO-
CERAMIC baffle system. This system uses a
lightweight, durable ceramic material above the
burner tubes to maintain the high temperatures in
the secondary combustion area and maintain the
low emission – high efficiency combustion you
desire. This new technology will not corrode, rust
dissolve or lose its strength, however it is vulnerable
to puncture or cracking due to rough handling.

Installation
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
Please use this section to plan how to locate your
stove in your particular situation. 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.
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 must be
protected as described on page 10.
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.
National Fire Protection Agency
Batterymarch Park
Quincy, MA 02269
1-800-344-3555
1-617-770-3000
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. *An example of a non-
combustible floor protector would be a hearth
constructed with a continuous layer of a listed
backer board (such as Wonder-Board or
Durock) used for ember protection with a tile,
brick, slate, or another noon-combustible facing.
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) Canada.
For horizontal chimney connector
installations, the floor protection must be
installed beneath the connector and 2”
beyond each side.
See Figure 2 for specific hearth details.

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.
