Warning
During the break-in fires (see page 18), you do not heat the stove to hightemperatures 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 thestove. This is from incomplete combustion of the wood and fromcondensation within the stove. This dripping liquid will only last for the
first couple of fires. After this the dripping will stop. You may want toplace a noncombustible material under the stove to protect your hearth
from stains until your break-in fires are complete.

Introduction
The walls of a Hearthstone stove produce bothradiant 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.

PERIODIC CHECKLISTPLEASE EXERCISE CARE WHEN LOADINGWOOD OR CLEANING YOUR STOVE, NOT TODAMAGE THE Thermo-Ceramic BAFFLE

Perform each of these tasks at the specified
intervals.

Located directly above the burner tubes in thefirebox, this white 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 ispunctured, it will cause the stove to function
improperly. You must replace the board through aqualified 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 fillup.
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 topage 21 – 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 21 –Gaskets)

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!

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.

▌

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 BODILYHARM.

CAUTION:
The ceramic baffle inside the firebox is notpacking material! Do not remove it from thestove prior to lighting.

Once the chimney fire has expired, leave theprimary air control closed and let the fire in thestove die out completely. Do not fire the stoveagain until the stove, stovepipe, and chimney
are all thoroughly inspected for any sign ofdamage. 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 THERMOCERAMIC baffle system. This system uses alightweight, durable ceramic material above theburner tubes to maintain the high temperatures inthe secondary combustion area and maintain the
low emission – high efficiency combustion you
desire. This new technology will not corrode, rustdissolve or lose its strength, however it is vulnerable
to puncture or cracking due to rough handling.

INSTALLING YOUR STOVE
Please use this section to plan how to locate yourstove in your particular situation. Consider both theclearances of the stovepipe and the stove itself tothe surrounding combustibles. Read this entire
section to obtain a sound understanding of how toproperly install your stove.

FLOOR PROTECTION
Install your stove on one of the following:First you must decide where your stove will beplaced. After choosing an appropriate spot, inspect
this location to make sure that the stove will haveenough clearance to combustible materials thatwould surround the stove. These combustibles can
include walls, floor, ceiling, furniture, and curtains.
You must carefully consider the clearances to all ofthese combustibles before actually connecting yourstove. When considering these clearances, alsodecide 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 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 following the tested methods (rear shield andclose clearance connector pipe) or by following thecriteria specified in NFPA 211 for US and CAN/ULC
B 365 for Canada.

Hearthstone Quality Home Heating Products, Inc. ®

*Noncombustible floor protector underneath thestove 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 andash removal opening. *An example of a noncombustible 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 istested and listed to UL 1618 can be used as thefloor protection if it meets the minimum size
requirement (38.5” by 41”) US and (98cm by 109cm) 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.

Craftsbury Model 8390

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 ofproviding outside air directly to the stove is that the
air used by the stove for combustion is taken fromoutside of the residence rather than from within theroom 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.

MINIMUM FLOOR PROTECTOR SIZEAND STOVE TO EDGE CLEARANCESThe outside air kit for this stove allows forthe direct connection of the stove's air intake to aminimum 3" (76 mm) diameter duct (supplied byothers) which leads to the outside of the house.
When considering placement of the duct from theoutside of the house to the hearth, keep in mind theneed to avoid structural members of the house. The
termination of the duct on the outside wall of thehouse should be located in such a manner so as topreclude the possibility of obstruction by snow,
leaves or other material and should be screened
against animals and insects.

It is very important to follow minimum clearances forchimney connectors to combustibles such as walls
and ceilings when installing the stove near noncombustible 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 MAYCOMPROMISE THE SAFTY OF THE
INSTALLATION.

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 tothe 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 prefabricatedresidential type building heating appliancechimney. Do not connect this stove to a chimney
serving another appliance; you will compromise
the safe operation of both the wood stove andthe connected appliance.

▌

WARNING:
DO NOT CONNECT THIS APPLIANCE TO ANY
AIR DISTRIBUTION DUCT OR SYSTEM.



A liner (listed to UL 1777 or ULC S635) createsan acceptable flue in a factory built fireplace or inan 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 thestove to a proper chimney.

VENTING CONFIGURATIONCOMPONENTS OF A VENTING SYSTEMINSTALLING A VENTING SYSTEM

The complete venting system will consist 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 andto 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 tothe 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 fromTo protect against the possibility of a house fire,you must properly install and constantly maintainthe venting system. Upon inspection, immediately
replace rusted, cracked, or broken components.

CONNECTING TO A PREFABRICATEDMETAL CHIMNEY

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 thestovepipe (without moving the stove) when you
periodically inspection or clean the stovepipe
connection and chimney.

When connecting the Craftsbury to a prefabricatedmetal chimney, you must follow, precisely, themanufacturer's installation instructions. Use only
Type HT (2100 deg. F), prefabricated metal chimneys
listed per UL 103 or ULC S629 standards.
▌

Install the stove as close as practical to thechimney, 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).

Make sure the size of the chimney’s flue isappropriate 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.)Long runs of stovepipe to increase heat dispersal
are not recommended. Using longer lengths ofstovepipe or more connecting elbows thannecessary increases the chances of draft resistanceand the accumulation of creosote buildup.

When purchasing a prefabricated chimney to installwith your stove, be sure to also purchase from thesame manufacturer all of the necessary components
such as the wall pass-through (or ceiling support
package), "T" section package, fire-stops (whenneeded), insulation shield, roof flashing, chimney
cap, and any other needed accessories. Follow the
manufacturer’s instructions when installing thechimney and accessories. In addition, be sure to
maintain all manufacturers’ recommendations for theproper clearances to the chimney.

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 canhelp regulate the draft. The Craftsbury requires adraft 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.

There are basically two ways to install aprefabricated metal chimney:

CONNECTING YOUR WOOD STOVE
You can install your Craftsbury to a prefabricatedmetal chimney or a masonry 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 theoutside of the residence

Whenever possible, choose an interior chimney. Aninterior 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 fluetemperatures than an interior chimney. An exteriorchimney’s draft is not as strong and may experience
increasedcreosote
accumulation.

Reversing the flue collar
The Craftsbury is vented either horizontally or
vertically by reversing the flue collar.

Consider two primary elements when connecting
your stove to a masonry chimney: the chimney itself
and the thimble where the stovepipe connects tothe chimney. Use only Code approved masonrychimneys with a flue liner.

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 HTrequirements or other approved material.






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.

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 thechimney.

Make sure the chimney’s cleanout is complete andworking properly. To avoid a loss of draft, thecleanout must close off completely. If allowed tocool, your stove will perform poorly and creosote
will build up in the chimney.

Exterior chimney requirements:
At least 1" (25 mm) clearance to combustible
structure.



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 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 yourmasonry chimney meets these minimum
requirements:

Chimney height requirements: (See Figure 6)
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.

Chimney wall construction:
 Brick or modular block at least 4" (102 mm)
thick.

This stove requires a minimum chimney height of
13 feet (4 m). The maximum allowable chimneyheight is 30 feet (9m).

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.

Do not operate the stove unless the ASH PAN
DOOR is tightly closed. This could cause thestove to overheat and damage the componentsof the stove.

CONTROLS AND FEATURES

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.

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.

Removable Door Handle
The front door handle is held in place with a springloaded ball bearing. If the handle does not stay inplace it can be adjusted. To do so, use a slottedjeweler’s screwdriver to adjust the setscrew on themetal end of the handle. Turn the setscrew

▌

Do not store Firewood within the stove's
specified clearances to combustible materials!

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.

BUILDING A FIRE

The following is a list of wood species and theirrelative BTU (British Thermal Unit) content. The
higher the BTU’s the longer the burn. Firewood withhigher BTUs is generally considered more ideal for awood stove.

Once you understand the controls of your woodstove and have chosen the appropriate firewood,
you are ready to start a fire.

BREAKING IN YOUR WOOD STOVEHIGH: Apple, Black Birch, Hickory, Locust, White
Oak, Black Beech, Mesquite
MEDIUM HIGH: White Ash, Beech, Yellow Birch,
Sugar Maple, Red Oak

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.

MEDIUM LOW: Black Ash, White Birch, Grey Birch,
Elm, Norway Pine, Pitch Pine, Black Cherry, Soft
Maple, Tamarack

The soapstone on the back and bottom in yourfirebox is intended to prevent thermal stress; leave itin place in the firebox at all times.

LOW: White Pine, White Cedar, Balsam Fir, Spruce,
Aspen, Basswood, Butternut, Hemlock

When you light your first fires, the wood stove will
emit some smoke and fumes. This is normal “offgassing” of the paints and oils used whenmanufacturing 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 willend once the stove is “cured”.

Moisture content also plays a key role in theperformance of your stove. Wood freshly cut from aliving tree (green wood) contains a great deal ofmoisture. 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.

During the break-in fires you will not be heating
the stove to the maximum temperatures you will
be 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 isdue to incomplete combustion of the wood andthe condensation within the stove. This liquid
will only last for the first couple of fires. After

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 forHearthstone Quality Home Heating Products, Inc. ®

17

Craftsbury Model 8390

this the dripping will stop. You may want toplace a noncombustible material under the stove
to protect your hearth until your break-in fires
are complete.

NORMAL OPERATION
If your stove is not used continuously or has notbeen used in quite some time, follow the break-in
procedure at least once to minimize the stress of a
hot fire on a cold stove before proceeding withnormal operation. We recommend one break-in fireat the start of each heating season. Prior to loading
the stove, make sure the ash grate is closed and theash pan door is tightly closed. If the ash grate is left
open or the ash door is loose, the stove will over-fireand could be damaged.

BUILDING A BREAK IN FIRE
1. Open the door and place five or six double
sheets of tightly twisted newspaper in thecenter of the firebox. Arrange kindling in acrisscross 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" (254mm) 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 thekindling 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 thegrate is in the closed position.
5. KEEP A WATCHFUL EYE ON YOURSTOVE 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 ofsplit cordwood should be added to the fire toreach safe break-in temperatures.
6. Once the stove is warm but not hot to thetouch, close the primary air control andallow the fire to die out completely.
7. Let the stove return to room temperature.

BUILDING A FIRE FOR EVERYDAY USE
1. Open the door and place five or six double
sheets of tightly twisted newspaper in thecenter of the firebox. Arrange kindling in acrisscross 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" (254mm) long.
2. Fully open the primary air control by pulling
the lever straight out from under the ash lip.
3. Light the paper under the kindling. Leave
the door slightly ajar momentarily until thekindling has started 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 door
and add logs, small at first, to build the fire
up. Make sure to keep the logs away fromthe glass in front in order for the air-washsystem to work properly. Otherwise, keep
the door and ash door tightly closed while
the stove is in use.
6. Once the fire is burning well, use the primary
air control to regulate the desired rate ofburn. Pulling the lever out, away from thestove front opens the PRIMARY AIR
CONTROL for a high rate of burn or pushing
it under the ash lip the stove will produce a
low rate of burn.

Your first three break-in fires should be built andmaintained 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 maybuild up quickly. We recommend a visual inspection(and cleaning if necessary) of your stovepipe andchimney once the break-in procedure is completed.

Hearthstone Quality Home Heating Products, Inc. ®

Note: When opening the door to reload or rearrange logs, it is advisable to open the door
just a crack, pause for a moment, then open
the door completely. This procedure will allow
the firebox to clear of smoke before the door
is opened fully. Also, reloading on a bed ofhot, red coals reduces smoking time and willbring fresh fuel up to a high temperature
rapidly.

18

Craftsbury Model 8390

Monitoring the temperature is the best way todetermine that the stove is over-firing. If you
suspect that your stove is over-firing, contact yourdealer immediately. Damage done by over-firing is
not covered by your warranty. Results of over-firing
can include: warped or burned out internal parts,
discolored or warped external parts, and damaged
enamel.

BURN RATEHIGH BURN: Fully load the firebox with wood on a
bed of hot coals or on an actively flaming fire andfully open the primary air control. A high burn rate isrecommended once or twice a day to fully heat thestovepipe and chimney, which will help minimize
creosote accumulation.

NOTE: ANY SYMPTOMS OF OVER-FIRING WILL
VOID YOUR WARRANTY!!

MEDIUM BURN: Set the primary air control to a midrange setting by pulling the air control about half way
out. This will be the appropriate setting for theheating needs of the area being heated. A medium
burn rate should be the typical setting and ispreferable if the stove is to be left unattended.

REMOVAL AND DISPOSAL OF ASHES
Ashes are best removed when the stove is cool. In
the morning before adding additional fuel is a goodtime for ash removal. Use protective fireplace
gloves when the pan is warm. Exercise extreme
caution when handling, storing or disposing ofashes.

LOW BURN: Close the primary air control for a lowburn rate. A low burn rate over extended periods oftime is not advisable as it may promote theaccumulation of creosote. The venting systemshould be inspected frequently if low burn rates aremaintained consistently.

To remove ashes from the firebox, sift the ashes
across the open ash grate using an ash hoe, ash
shovel, or other suitable implement. Wearing thefireplace gloves, open the ash door by lifting thehandle bar up and allow the ash pan door to drop
into the open position. Remove the ash pan bypulling the handle on the ash pan and sliding it
carefully out of the stove. Dump the ashes as
described below. If needed, the pan can be used asa scoop to remove any ashes still remaining in theash dump area. Re-insert the ash pan by pushing it
in all the way. Wearing the fireplace gloves, lift theash door and secure it by pushing down the handlebar.

CLEAN BURN: After reloading with wood, burn thestove with the 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.

OVER-FIRE CAUTION
Over-firing means the stove is operating attemperatures
above
the
recommended
temperatures outlined above in the BURN RATE
section. Over-firing should be carefully avoided
since it will cause damage to the stove. Symptomsof over-firing include short burn times, a roaring
sound in the stove or stovepipe, and discoloration of
the stovepipe.

Ashes should be dumped from the ash drawer into a
metal container with a tight fitting lid. Do not place
any other items or trash into the metal container.
Replace the lid onto the container and allow theashes to cool. Do not place the ash disposal
container on a combustible surface or vinyl flooring,as the container will be hot!

Over-firing can be caused by excessive draft,inappropriate fuel, and operator error. Correct anover-fire situation as follows:
EXCESSIVE DRAFT: Contact your dealer
to have a draft reading taken. Any draft in excess of
0.1 wc requires a damper in the stovepipe. Someinstallations may require more than one damper.
INAPPROPRIATE FUEL: Do not burn coalkiln dried lumber, driftwood, wax logs or anythingother than natural cordwood.
OPERATOR ERROR: Make sure all thegaskets are in good condition. Replace worn out orcompressed gaskets. Do not burn the stove with thefront or ash doors in the open position.

Hearthstone Quality Home Heating Products, Inc. ®

Pending disposal, place the closed ash container on
a noncombustible floor or on the ground, well awayfrom all combustible materials. Ashes should be
retained in the closed container until all cinders havethoroughly cooled.
Ashes should NEVER be placed in wooden or
plastic containers, or in paper or plastic bags, nomatter how long the fire has been out. Coals within
a bed of ashes can remain hot for several days once
removed from the firebox.

19

Craftsbury Model 8390

Maintenance
The venting system must be inspected at the stoveconnection and at the chimney top.
Coolersurfaces tend to build creosote deposits quicker, so
it is important to check the chimney at the top(where it is coolest) as well as from the bottom near
the stove.

MONITORING STOVE TEMPERATURES
Monitor the stove temperatures with a stove
thermometer (available from your dealer) placed on
the top center of the stove. The thermometer could
read as high as 600°F (427°C) on high burn and
300-400°F (149°C-204°C) on low burn.

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 yourdealer for the name of a certified chimney sweep inyour area (your dealer may be a certified sweep!).

Do not over-fire the stove. (Refer to page 19).

CREOSOTE FORMATION AND NEED FORREMOVAL

It is also recommended that before each heating
season the entire system be professionallyinspected, cleaned and repaired, if necessary.

When combustion of the wood is incomplete due tosmoldering, low temperature fires, it produces tar
and other organic vapors, which combine withexpelled moisture to form creosote.
These
creosote vapors condense in the relatively coolchimney flue of a slow-burning fire. As a result,creosote residue accumulates on the flue lining.
When ignited, this creosote makes an extremely hot
fire, which may damage the chimney or evendestroy the house.
When burning wood, thechimney connector, and chimney should be
inspected at least once every two months during
the heating season to determine if a creosotebuildup has occurred.

Use of chimney sweeping logs, sprays, or powders
may aid in the mechanical cleaning process,however, they should not be used as a substitutefor the inspection and brushing of the flue andstovepipe.

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.

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 andthe venting system.

To replace door gaskets, first pull out the old gasket
with needle nose pliers. Clean any debris from thegasket channel with a wire brush. Apply a thin,continuous bead of the gasket cement to the
prepared channel and push the new gasket into
place without stretching or bunching the gasket
material. Cut off any excess rope gasket with sharp
scissors. The door should be shut immediately to
fully press the gasket into place and assure a
positive seal.

2. After reloading with wood, burn the stovewith the primary air control fully open for 20
to 30 minutes. This manner of operation
ensures early engagement of thesecondary combustion system which, whenengaged, minimizes creosote buildup in thechimney.

The Craftsbury requires the use of the following
gaskets sizes:

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" (6mm) has accumulated, it should be removed toreduce the risk of a chimney fire.

8. Install the door onto the stove.

GLASS
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 withcommercial stove glass cleaners, which areavailable from your local dealer. Never attempt toclean the glass while the fire is burning or the glass
is hot. Following the instructions provided with thecleaner can clean most deposits. To clean heavier
deposits, open the door and remove it by tapping
up on the hinge pins (take care to save hinge pins
and washers for reuse). Lay the door face down on
a workbench 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 topenetrate rather than running off the surface of theglass. 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.

CAST IRON
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.

The front door glass is a ceramic, shock-resistantglass, made specifically for use in woodstoves. Do

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.

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
which leads 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
downdrafts. When selecting a site for a new
chimney, take care to consider the placement ofother objects in the vicinity 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
downdrafts. Wind caps, like the Vacu-Stack, for the
top of the chimney are available as possible
corrective measures here
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 thechimney, leaky stovepipe joints, a poor stovepipeto-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.

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°F (200°C)
stovepipe confirms the stove is supplying sufficientheat. Keep in mind that your house itself will
regulate room/house temperatures. How well thewalls, floors and ceilings are insulated, the number
and size of glass windows, the tightness of outside
doors, and the construction or style of your house(vaulted ceilings or other open spaces which collectlarge percentages of heat) 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 evenforce the smoke to spill into the room. If yourchimney is the proper size and a strong draft is noteasily established, there is the possibility of thechimney being too cold. Again, hot chimneys
promote a stronger 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 very dry kindling and small pieces ofcordwood to obtain a quick, hot fire. Tend the fire
frequently with small fuel until the chimney is hot
and the draft is well established.

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
