Congratulations! You have just invested in a most unique
wood burning stove – the Mansfield Wood Burning Stove
from HearthStone Quality Home Heating Products Inc®.
The Mansfield, model 8011, is our largest and one of the
cleanest burning, EPA certified, non-catalytic wood
burning stoves. At 3.2 cubic feet capacity and 2.8 grams
per hour particulate you can be proud to join the
HearthStone family with our Premier Wood Burning
Stove. The generous depth allows for straight in loading
of wood up to 20 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 Mansfield blends modern technology with the
unique beauty and heating qualities of soapstone
(traditionally renowned 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 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 with a
special connector pipe and special wall coverings as
Introducing Your
Mansfield Wood Stove
specified by this manual, the NFPA 211 codes, and 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.
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 presented here 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.

Follow these safety precautions:
q Never modify this stove in any way, especially the
primary air control system.
q 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.
q 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.
q Never use the stove if the ash pan door is open,
damaged, not in place, or not sealing.
q Never use a wood grate or other device to elevate the
fire.
q Do Not allow logs to rest against or otherwise come
in contact with the glass when the door is closed.

q Never put articles of clothing or candles on a hot
stove.
q Do Not connect the stove to a flue that is serving
another appliance. (See page 10)
Other safety guidelines
q Keep all combustible items such as furniture, drapes,
clothing, and other items, at least 36" (0.92 m) from
the stove (See page 8)
q Install a smoke detector, preferably in an area away
from your wood stove.
q Keep a fire extinguisher handy. We recommend the
type rated "A B C."
q Dispose of ashes properly. (See page 17)
q Keep children and pets away from the stove; they
could be burned by touching a hot stove.
q Clean your chimney system as needed. (See page 18)

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 begin 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 the use of your stove. (Please see page 18Creosote 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 gask et. (Refer to
page 18 – 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. Call the fire department – immediately!
2. If the fire is too threatening, leave the area and wait
for the fire department. If not, perform the next three
steps.
3. Close the primary air control. (see page 14)
4. Close the stovepipe damper (if present).
5. 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.

Setting Up Your
Mansfield Wood Stove
UNPACKING
HearthStone Stoves packages your Mansfield stove with
the greatest 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 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. Depending on your floor, you can install your stove
as it is, or use a floor protector.
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 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 for
your pipe for actual clearances. The diagrams in this
manual represent typical installations, but are specific to
the Sim pson 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.
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
HearthStone Quality Home Heating Products Inc ® Mansfield Model 8011
211 for specifications and complete details. You can
obtain this information directly from NFPA.
National Fire Protection Agency
Batterymarch Park
Quincy, MA 02269
1-800-344-3555
1-617-770-3000
HEARTH REQUIREMENTS AND FLOOR
PROTECTION
If the floor is wood or other combustible flooring, the
stove must be placed on non-combustible floor protection
that extends 16 inches to the front and 8 inches to either
side of the front door opening.
The unit must be placed on a non-combustible floor
protector that extends 16” in front and 6” to each side of
the unit. If installed in an alcove at reduced clearances
with NFPA 211 wall protection, the area in front of the
unit must have an additional insulative R-value of .8, or a
listed floor protection must be used.
The floor protector for the stove must have minimum
dimensions of 34-1/2” x 46” (876 x 1168 mm) and must
be placed as illustrated here:
FLOOR PROTECTOR SIZE AND
STOVE TO EDGE CLEARANCE
From fuel door
opening
The chimney connector must also have floor protection
under it, and extending 2 inches (50 mm) beyond each
side.

OUTSIDE AIR SUPPLY
An outside air source may be connected directly to this
stove using an outside air kit (90-57004). 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 air-tight
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 consider ing 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.
See illustration for all connection options. Choose the
one most convenient. 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.

CLE ARANCES TO COMBUSTIBLES
Please use this section to plan the layout for your
stove. Consider clearance of pipe to combustibles
and stove to combustibles. More specifics on
installation follow.
You must follow minimum clearances for the Mansfield
stove to combustibles such as walls and ceilings. You may
reduce the general clearances if installing the stove near
Protected Surfaces (see ”CLEARANCES TO NFPA 211
