Introduction
Congratulations! You have just invested in a mostunique wood burning stove – the Mansfield Wood
Burning Stove from Hearthstone Quality Home
Heating Products Inc®. The Mansfield, model 8011,
is one of our largest and one of the cleanest burning,
EPA certified, non-catalytic wood burning stoves. At
3.2 cubic feet firebox capacity and a low 2.8 grams
per hour of particulate emissions you can be proud
to join the Hearthstone family with our Premier Wood
Burning Stove. The generous depth allows forstraight in loading of wood up to 20 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 Mansfield
blends modern technology with the unique beautyand heating qualities of soapstone (traditionallyrenowned 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 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 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.

Make sure to install your stove:
Accordingtotherecommendations.

manufacturer's

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 logs to rest against or otherwise
come in contact with the glass when the door isclosed.

In accordance with all applicable codes.

Do Not slam the door or use it to force wood into the stove.

With the proper sized chimney.

Never over-fire your stove. (See page 17)

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 ash pan tray fully inserted and the ashdoor closed tightly.
Inspect the stove pipe, chimney connector andchimney, as recommended.
Ensure the removable ash lip is in place while
using the stove. If the ash lip is not installed
properly, the hearth may exceed safe
temperatures.

Never put articles of clothing or candles on a hot
stove.
Do Not connect the stove to a flue that isserving another appliance. (See page Error!
Bookmark not defined.)
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 Error!
Bookmark not defined.)
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. (Seepage 18)

Hearthstone Quality Home Heating Products, Inc. ®

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 fillup.
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. (Pleasesee page 18-Creosote Formation and Need For
Removal)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 18 –Gaskets)
At 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.

Thermo-Ceramic Baffle System
To enhance the combustion efficiency and reduce
the emissions of the fire in your stove Hearthstone
developed an advanced THERMO-CERAMIC baffle
system. This system uses a lightweight, durable
ceramic material above the burner tubes to maintainthe high temperatures in the secondary combustion
area and maintain the low emission – high efficiency
combustion you desire. This new technology will notcorrode, rust dissolve or lose its strength, however it
is vulnerable to puncture or cracking due to roughhandling.
PLEASE EXERCISE CARE WHEN LOADINGWOOD OR CLEANING YOUR STOVE, NOT TODAMAGE THE THERMO-CERAMIC BAFFLE

Located directly above the burner tubes in thefirebox, this gray sheet of material will break if woodor cleaning brushes impact it. Be careful whenloading and cleaning your stove to not break thismaterial. If this piece has been fractured or a hole isMansfield Model 8011

punctured, it will cause the stove to function
improperly. You must replace the board through aqualified Hearthstone dealer.

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 andwait for the fire department. If not, perform thenext three steps.
3. Close the primary air control. (see page 14)
4. Close the stovepipe damper (if present).
5. Keep the stove front, and ash doors closed!
WARNING: DO NOT ATTEMPT TO PUT OUT ASTOVEPIPE OR CHIMNEY FIRE BY THROWINGWATER ONTO THE STOVE, STOVEPIPE, OR
CHIMNEY. THE EXTREMELY HIGHTEMPERATURE ASSOCIATED WITH SUCH FIRESCAN CAUSE INSTANTANEOUS STEAM AND
SERIOUS BODILY HARM.

Once the chimney fire expires, leave the primary aircontrol closed and let the fire in the stove die out
completely. Do not fire the stove again until thestove, stovepipe, and chimney are all thoroughly
inspected for any sign of damage. You must correct
any damage before using your stove again.

Installation
UnpackingHearthstone packages your Mansfield stove with thegreatest care, so that it ships safely. Under certain
circumstances, however, damage can still occur
during transit and handling. When you receive yourstove, unpack it carefully, inspecting your stove andall parts for damage. Also, ensure that all parts areincluded. If any parts are damaged or missing,please contact your dealer immediately.

Installing Your StoveFirst you must decide where your stove will reside.
After choosing an appropriate spot, inspect thislocation to ensure that the stove will have enoughclearance 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 thekind of floor the stove will rest on. Depending on
your floor, you can install your stove as it is, or use afloor protector.

Hearth Requirements & Floor
Protection
If the floor is wood or other combustible flooring, thestove 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 (US).
If installed in an alcove at reduced clearances with
NFPA 211 wall protection, the area in front of theunit 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” x 40” (864 x 1016 mm) and must
be placed as illustrated here:

Use this section to plan how to locate your stove inyour particular location. Consider both theclearances of the stovepipe and the stove itself tothe surrounding combustibles.
Read this chapter to obtain a sound understandingof how to properly install your stove.
If you use a close clearance connector pipe, it must
be tested to UL standards and listed. Check thelisting for 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.

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 for specifications andcomplete details. You can obtain this information
directly from NFPA.

Figure 3*An example of a non-combustible floor protector would be ahearth 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.

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 tothis stove using the optional outside air kit (PN 90-

Hearthstone Quality Home Heating Products, Inc. ®

Mansfield Model 8011

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 theresidence 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 directconnection of the stove's air intake to a minimum 3"(76 mm) diameter duct (supplied by others) whichleads to the outside of the house. When considering
placement of the duct from the outside of the houseto the hearth, keep in mind the need to avoid wiringand structural members in the wall.
See the following illustrations for all connection
options. Choose the one most convenient. Locate
the termination of the duct on the outside wall of thestructure in such a manner so as to preclude thepossibility of obstruction by snow, leaves or othermaterial. Screen the opening against animals andinsects (any screen, duct, clamps, and hoodsupplied by others).

Clearances To Combustibles
Use this section to plan the layout for your stove.
Consider clearance of connector, and chimney pipe
to combustibles and stove to combustibles. Morespecifics on installation follow.
You must follow minimum clearances for the
Mansfield stove to combustibles such as walls andceilings. You may reduce the general clearances if
installing the stove near Protected Surfaces (see thefollowing diagrams and the table on page 8).

Figure 7

Figure 5

Figure 8
If you use a rear heat shield to obtain reduced
clearances, you must use the optional rear heatshield manufactured by Hearthstone available
through your local dealer. Close clearance
connector pipe must be tested to UL standards andlisted. Check listings of your pipe for actual
clearances. Shown are measurements typical onlyand specific to Simpson Dura Vent DVL brand.
Clearances cannot be reduced without the use of
the rear heat shield and/or with close clearance
connector pipe and/or by protecting the surfaces per
NFPA 211 standards

Venting Components & Configuration
Components of a Venting System

Installing 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.

Stovepipe sections must be attached to the stove
and to each other with the crimped end toward thestove. If creosote builds up, this allows the creosote
to run into the stove and not the outside of thestovepipe and onto the stove.

To protect against the possibility of a house fire, youmust properly install and constantly maintain theventing 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
to the chimney.
A wall pass-through (or chimney support
package) also keeps the walls from igniting.
You must use one when connecting through awall or ceiling to a prefabricated chimney.
Only install this stove to a lined masonrychimney or an approved high temperature
prefabricated residential type building heating
appliance chimney. Do not connect this stove toa chimney serving another appliance; you willcompromise the safe operation of both the woodstove and the connected appliance.
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.

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 metalscrews into the holes pre-drilled in the flue collar.
Leaving off the screws can cause joints to separate
from the vibration that results from a creosotechimney 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 periodicallyinspection 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 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 Mansfield. 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 Mansfield 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 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 Mansfield to a prefabricatedmetal chimney or a masonry chimney.

Connecting to a Prefabricated Metal
Chimney
When connecting the Mansfield to a prefabricatedmetal chimney, you must follow, precisely, themanufacturer's installation instructions. Use only
Type HT (2100 deg. F), prefabricated metalchimneys listed per UL 103 or ULC S629 standards.
WARNING: DO NOT CONNECT THE STOVETO A CHIMNEY FLUE SERVING ANOTHERAPPLIANCE.

Ensure the size of the chimney’s flue is appropriate
for the Mansfield. The Mansfield 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
installing the chimney and accessories. In addition,
be
sure
to
maintainallmanufacturer’s
recommendations for the proper clearances to thechimney.
There are basically two
prefabricated metal chimney:

ways

to

installFigure 10a

1. An interior installation where the chimney
passes inside the residence through the ceilingand roof.
2. An exterior installation where the chimney
passes through the wall behind the stove thenup the outside of the residence.
Whenever possible, choose an interior chimney. Aninterior chimney heats up more quickly and retains
its heat; thus promotes a better draft anddiscourages 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.

203 mm) tile size for best results. An oversized flue
will contribute to the accumulation of creosote.
Minimum Requirements:
At least 3’ (0.91 m) higher than highest part of roof
opening through which it passes and at least 2’ (0.61m) higher than any part of the roof within 10’ (3 m).
Use the following checklist to ensure that yourmasonrychimneymeets

thick.
A rubble or stone wall at least 12” (305mm)
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 orother 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.
Figure 12

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.
Make sure the chimney’s cleanout is complete andworking properly. To avoid a loss of draft, thecleanout must close off completely. If not, thechimney will cool, your stove will perform poorly, andcreosote will build up in the chimney.
Make sure the size of the chimney’s flue isappropriate for this stove and that it is not too large.
Use a masonry chimney with an 8” x 8” (203 mm xExterior chimney requirements:

Operation
Once your Mansfield is set in place, connected, andassembled, you are ready to light a fire.
Hearthstone tests each wood stove before we ship,
so you should be able to easily light your first fire.
WARNING: HOT WHILE IN OPERATION. KEEP
CHILDREN, CLOTHING AND FURNITURE AWAY.
CONTACT MAY CAUSE SKIN 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 & 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:
A fixed handle isprovided to operate the front loading door. The 10
o’clock position is open; the 7 o’clock position isclosed. Pull on the door handle to make sure it isproperly latched.
PRIMARY AIR CONTROL: This feature is locatedon the lower left side of the stove, under theremovable ash lip. The primary air control allows
you to regulate the amount of air entering thefirebox. Generally, the more air allowed into thefirebox, the faster and hotter the rate of burn;conversely, less air creates a slower burn. Push thelever to the left to open the primary air control; push
the lever to the right to close the primary air control.
ASH PAN: The ash pan access door is locatedunder the ash lip. The ash pan collects burned ash
from a fire and allows you to conveniently remove
the ash from your wood stove. To open the door,
rotate the handle counter clock-wise. Clean thefirebox of ashes as required by sliding the ash grate
open, sifting the ashes across the grate into the ashpan, then returning the grate to its closed position.
The ash pan is easy to remove and has a handle forconvenient disposal of ashes. Once you remove theashes, close the ash pan access door and rotate thehandle clock-wise to latch.

Choosing Firewood
Burn only natural firewood (known as cordwood)in the Mansfield 8011 Woodstove. This stove is
not designed to burn other fuels.
CAUTION: DO NOT USE CHEMICALS OR
FLAMMABLE FLUIDS TO START THE FIRE. DO
NOT USE CHARCOAL, PELLETS, COAL,ARTIFICIAL LOGS OR ANY OTHER MATERIALSAS FUEL; THEY ARE NOT SAFE. DO NOT BURNGARBAGE OR FLAMMABLE FLUIDS.

The quality of your firewood directly affects heat
output, duration of burn and performance of yourstove. Softwoods generally burn hotter and faster,while hardwoods burn longer and produce better
coals. Density and moisture content are two criticalfactors to consider when purchasing wood for yourstove.
The following is a list of some wood species andtheir relative BTU (British Thermal Unit) content. The
higher the BTU content, the longer the burn.
Firewood with higher BTUs is generally ideal for awood stove.

Moisture content also plays a key role in theperformance of your stove. Wood freshly cut from aliving tree (green wood) contains a great deal ofHearthstone Quality Home Heating Products, Inc. ®

moisture. As you might expect, green wood burns
poorly. You must season green wood before using it
in your wood stove. To season green wood properly,
split, stack, and allow it to air dry for a period of one
year. Green wood may provide less than 2000 Btu
per pound, whereas dry wood can provide up to7000 Btu per pound.
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 forstacking, 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."CAUTION: DO NOT STORE FIREWOOD WITHINTHE STOVE'S SPECIFIED CLEARANCES TOCOMBUSTIBLE MATERIALS.

Building A Fire
Once you understand the controls of your woodstove and have the appropriate firewood, you areready to start a fire.
WARNING: NEVER USE GASOLINE, GASOLINETYPE LANTERN FUEL, KEROSENE, CHARCOAL
LIGHTER FLUID, OR SIMILAR LIQUIDS TO START
OR 'FRESHEN UP' A FIRE IN THIS HEATER.
KEEP ALL SUCH LIQUIDS WELL AWAY FROM
THE HEATER WHILE IT IS IN USE.

Breaking In Your Wood Stove
It is imperative that your stove is "broken in" slowly.
Cast iron must be "seasoned"; over-firing a new
stove may cause castings to crack or may damage
other stove parts. Driving moisture out of thesoapstone slowly minimizes the “shock” to the stone
at its first exposure to high firebox temperatures.
Also, curing the asbestos-free furnace cement slowly
ensures adequate sealing and bonding.
The bottom layer of soapstone in your firebox isintended to prevent thermal stress and should
remain in place in the firebox at all times.
When you light your first fires, the woodstove will
emit some smoke and fumes. This is normal “offgassing” of the paint used when manufacturing thewoodstove. 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 ofoperation. The odor and smoke will end once thestove is “cured”.
The first few fires of the season may produce otherodors from impurities that exist in the area

Mansfield Model 8011

immediately surrounding the stove. Some potential
impurities are cleaning solvents, paint solvents,
cigarette smoke, and soot from scented candles, pethair, dust, adhesives, a new carpet, and new
textiles. These odors will dissipate over time. You
can alleviate these odors by opening a few windowsor otherwise creating additional ventilation aroundyour stove. If any odor persists, contact your dealer
or an authorized service technician.

Building a Break-In Fire
1) Open the door and place five or six double
sheets of tightly twisted newspaper in the centerof the firebox. Arrange kindling in a crisscrosspattern over the newspaper. Kindling should beapproximately ten pieces, 1/2" (13 mm) indiameter and 10" to 18" (254 mm to 457 mm)long.
2) Fully open the primary air control by pushing thelever to the left.
3) Light the paper under the kindling. Leave
the front door slightly ajar momentarily until thekindling has started to burn and draft begins topull.
4) Close the door and allow the fire to burn. Keep
the door and ash drawer closed while the stoveis in use. Make sure the ash door is in theclosed position.
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 and allow thefire to die out completely.
7) Let the stove return to room temperature.
Your first fire and first fire each season thereafter
should be built and maintained as outlined above.
Your patience will be rewarded by a properly
seasoned stove.
NOTE: Because of the cool flue gas
temperatures present during the break-in
procedure, creosote may build up quickly. Your
window may also get dirty. A good hot fire willclean it.
If you adhere to the operating procedures in thismanual, the steel, cast iron, stone and refractorycomponents of your stove will give you many yearsof trouble-free use. With use, the color of theHearthstone Quality Home Heating Products, Inc. ®

soapstone will change and small fractures may
appear on the surface. These changes do not affectthe function of the stove. If a stone breaks
completely, it must be replaced
Avoid the following conditions that can cause theglass, refractory panels, steel or cast iron pieces tobreak:Do not throw wood into the stove.
Do not use the door as a lever to force wood into
the stove.
Do not load wood encrusted with ice into aburning stove - the thermal shock can cause
damage.
Do not use a manufactured log grate. Burn thefire directly on the soapstone lining the cast ironbottom of the firebox.

Normal Operation
Prior to loading the stove, ensure the ash grate,
refractory soapstone, and the ash pan are in place.
Ensure the ash door is closed to prevent over-firing.

crack, pause for a moment then open the door
completely. This procedure allows the firebox toclear of smoke before the door is open fully. In
addition, reloading on a bed of hot, red coals
reduces smoking time and brings fresh fuel up to ahigh temperature rapidly.

Burn Rate
HIGH BURN: 500-600 Degrees F. Fully load thefirebox with wood on a bed of hot coals or on an
actively flaming fire and fully open the primary aircontrol. A high burn rate once or twice a day for 35
to 45 minutes to heat the stovepipe and chimney
fully, will help minimize creosote accumulation.
MEDIUM HIGH BURN: 450-500 Degrees F. With
the primary air control in the fully open position,
push the control lever about ¼ of its travel to theright.
MEDIUM LOW BURN: 400-450 Degrees F. With theprimary air control in the fully open position, push
the lever about half to two thirds of the way to theright. A medium-low burn rate is the typical setting
and is preferable if the stove is unattended.

1) Open the front door and place five or six double
sheets of tightly twisted newspaper in the centerof the firebox. Arrange kindling in a crisscrossconfiguration over the newspaper. Useapproximately 10 pieces of kindling, 1/2" (13mm) in diameter and 10" to 16" (254 mm to 406mm) long.

LOW BURN: Less than 400 Degrees F. Push theprimary air control inward all the way to the right.
This closes the air shutter to its minimum opening. A
low burn rate over extended periods is not advisable
as it can promote the accumulation of creosote.
Inspect the venting system frequently if using low
burn rates consistently.

2) Fully open the primary air control by pushing thelever fully to the left.

Over-Fire Caution3) Light the paper under the kindling. Leave thefront door slightly ajar momentarily until thekindling begins to burn and draft begins to pull.
4) Close the door and allow the fire to burn.
5) Once the kindling is burning, open the front door
and add logs, small at first, to build the fire up.
Ensure you keep the logs away from the glass infront in order for the air-wash system to work
properly. Keep the front door and ash door
closed while the stove is in use.
6) Once the fire is burning well, use the primary aircontrol to regulate the desired rate of burn.
Pushing the lever 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.
The air control does not close completely.
Note: When opening the front door to reload or rearrange logs, it is advisable to open the door just aOver-firing means the stove is operating attemperatures above normal temperatures reachedduring High Burns outlined in the BURN RATE
section. Carefully avoid over-firing, as it will damage
the stove. Symptoms of chronic over-firing can
include warped components, short burn times, aroaring sound in the stove or stovepipe, anddiscoloration of the stovepipe. A properly installed
stove using fuel and following operating proceduresas outlined in this manual should not over-fire.
Excessive draft, inappropriate fuel, and operator
error can cause over-firing. Correct an over-firesituation as follows:
EXCESSIVE DRAFT: Contact your local dealer
to have a draft reading taken. Any draft inexcess of 0.1 WC requires a damper in thestovepipe. Some installations may require morethan one damper.

Hearthstone Quality Home Heating Products, Inc. ®

INAPPROPRIATE FUEL: Do not burn coal; kiln
dried lumber, wax logs or anything other thannatural cordwood.
OPERATOR ERROR: Ensure all the gaskets
are in good condition. Replace worn out orcompressed gaskets. Do not burn the stove withthe front door in the open or partially open
position.
If you suspect that your stove is over-firing,
discontinue use and contact your dealer
immediately. Damage caused by over-firing is notcovered by your warranty. Results of over-firing
can include warped or burned out internal parts,
cracked vermiculite panels, discolored or warped
external parts, and damaged finish.

the firebox if preferred. It is important to prevent
ashes from building up around the front door
opening or they will spill out, or they can pack into
the gasket channel and prevent proper sealing. To
remove ashes, sift the ashes across the grate into
the ash pan. The ash pan is easy to remove and has
a handle for convenient disposal of ashes.
Dump ashes from the ash pan directly into a metal
container with a tight fitting lid. Do not place anyother items or trash into the metal container. Do notpour water into the container. Replace thecontainer’s lid and allow the ashes to cool. Neverplace the ash disposal container on a combustible
surface or vinyl flooring, as the container could be
hot!

Removal & Disposal of Ashes

Pending disposal, place the closed ash container on
a noncombustible floor or on the ground, well awayfrom all combustible materials, liquid fuels, orvehicles. Retain ashes in the closed container until
all coals thoroughly cool.

Remove ashes only when the stove is cold. Use aprotective fireplace glove if the ash pan is warm.
Exercise extreme caution when handling, storing or
disposing of ashes.

If the ashes are disposed of by burial in soil orotherwise locally dispersed, they should be retainedin the closed container until all cinders havethoroughly cooled.

The ash pan is located behind the ash door at thebottom of the stove under the ash lip. The ash pancollects burned ash from a fire and allows you to
remove the ash conveniently from your woodstove.
Clear the firebox of ashes, and do not let them build
up too high. You can leave a thin layer of ashes in

NEVER place ashes in wooden or plastic containers,in trashcans with other trash, or in paper or plastic
bags, no matter how long the fire has been out.
Coals within a bed of ashes can remain hot forseveral days once removed from the firebox.

ANY SIGNS OF OVER-FIRING WILL VOID YOURWARRANTY!

MaintenanceMonitoring 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 600 F (427 C) on high burnand 300-400 F (149-240 C) on low burn.
Do not over-fire the stove. (refer to previous
section).

Creosote Formation & Need for
RemovalWhen 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.
To prevent the buildup of creosote:
1. Burn the stove with the primary air control fully
open for 30 minutes daily to burn out creosote
deposits from within the stove and the venting
system.
2. 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.
The stovepipe connector and chimney should be
inspected at least monthly during the heating season
to determine if a creosote build-up has occurred. 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 is remaining dirty, your operating
temperatures are low, therefore there is a higher riskof creosote buildup.
The venting system must be inspected at the stoveconnection and at the chimney top. Cooler surfaces
tend to build creosote deposits quicker, so it isimportant to check the chimney at the top (where it iscoolest) 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!).
It is also recommended that before each heating
season the entire system be professionallyinspected, 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, which includes
instructions and gaskets for your stove.
The procedure for replacing gaskets on the glass isreviewed on page 19.
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:
GLASS: 60" (152 mm) Length, 3/4" (19 mm) Wide,
Adhesive Backed Black Tape
DOOR: 60" (152 mm) Length, 3/8" (9 mm) Diameter,
Low Density Black Tube
ASH DOOR: 32" (81 mm) Length, 1/4" (6 mm)
Diameter, Low Density, Black TubeGlass
Do not operate the stove with a broken door glass.
Do not abuse the front door by striking or slamming.
When necessary, the glass can be cleaned with low
alkaline content commercial stove glass cleaners,
which are available from your local dealer. Neverattempt to clean the glass while the fire is burning or
the glass is hot. Most deposits can be cleaned byfollowing 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 work bench or table. Apply the cleaner to theglass and allow it to set for a few minutes. By laying
the door flat, it will allow the cleaner to penetrate

Hearthstone Quality Home Heating Products, Inc. ®

Mansfield Model 8011

rather than running off the surface of the glass.
Wipe the cleaner off with a soft cloth.
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. Contact your local dealer for replacement
glass, which is accompanied with instructions andeverything needed for the repair. If you replace theglass yourself, wear work gloves and safety glasses.

5) Peel the paper backing from the tape gasket.
Apply the new gasket to the new glass as
illustrated.
6) Place the gasketed glass onto the door.
7) Screw the glass retainer clips back on the door.
8) Install the door.

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.
Care must be taken not to scratch or chip the stone.
Do not set items that may 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. Withnormal use, hair line or surface cracks may appear
in the stone. Such cracks do not affect the integrity
or operation of the stove and do not require
replacement.

Cast Iron

gasket1) Remove the door by lifting it straight up off thehinges with the hinge pins remaining in the door.
2) Place the door face down on a flat, smoothsurface.
3) Apply penetrating oil to the screws in the glass

the glass from the door.
4) Carefully lift the damaged glass from the door
and discard.

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 theoriginal appearance of painted cast iron. Use adamp sponge to wipe clean. Dry the cast ironthoroughly to prevent rusting.
Enamel castings can be cleaned with a standard
glass cleaner. With time and use, a very fine, subtle
network of crazed 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 or not your stove is
producing adequate heat, the best way totroubleshoot the problem is to monitor thetemperature of the stack. A 400 degree F (200degree C) stovepipe confirms the stove is supplying
sufficient heat. Keep in mind that your house itself
will regulate room/house temperatures. How well
the walls, floors and ceilings are insulated, thenumber and size of glass windows, the tightness ofoutside doors, and the construction or style of yourhouse (vaulted ceilings or other open spaces whichcollect 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
pressure, which prevents the smoke from rising out
the chimney. Oversized flues are also more difficult
to heat 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
the chimney 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, such as clothes dryers, bathroom fans or cook
stove exhaust fans, are in operation within thehome. Outfitting your stove with the optional outside
air supply adaptor connected to an air duct whichleads to the outside of the building should correct
this problem.

TALL TREES OR BUILDINGS: These obstructions,when located in proximity to the top of the chimney
can cause chronic or occasional down-drafts. Whenselecting a site for a new chimney, take care toconsider the placement of other objects in thevicinity of the proposed chimney location.
WIND VELOCITY: Generally, the stronger andsteadier a wind, the stronger (better) the draft.
However, "gusty" wind conditions may cause erratic
down-drafts.
BAROMETRIC PRESSURE: Chimney drafts are
typically sluggish on balmy, wet or muggy days.
This is 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, or a leaky chimney may cause
inadequate draft.
SEASONAL FACTORS: Early fall and late springare generally difficult seasons in which to establish
proper drafts. The colder the outside air (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 ora cold chimney may be the cause. Try starting thefire by using small kindling and fuel to obtain a quick,hot fire. Tend the fire frequently with small fuel until
the chimney is hot and the draft is well established.
