dried, seasoned wood, as compared togreen or freshly cut wood.
Use caution when loading firewood into a
hot stove.
Keep the fuel loading door closed at all
times except when loading wood.
Keep the ash pan tray fully inserted.
Avoid grease build-up when cooking on the
top surface. Clean the surface regularly afterusing the cook top surface.
Use care when cooking on the glass top.
Scratching the surface will weaken andshorten the life of the glass. (Pick up
your cooking pots pans instead of slidingthem on the surface.)
Never modify this cook stove in any way.
Never burn kiln dried wood, painted ortreated wood, solvents, trash, plywood,colored or glossy paper, artificial logs,
cardboard, coal, garbage or driftwood.
Especially, do not burn coal in this stove.
Never Use gasoline type fuel, kerosene,
charcoal lighter fluid, or other liquid fuels or
solid fire starters to start or invigorate thefire. These fuels can possibly generate
carbon monoxide, which can sap the supplyof oxygen or even create an explosion.
Keep all such materials away from thestove.
Never use a wood grate andirons or otherdevice to elevate the fire.
Do not allow logs to rest against orotherwise come in contact with the glass
when the door is closed.
Do not slam the door or use it to force woodin to the cook stove.
Never over-fire your cook stove. (See page
19)
Never put articles of clothing or candles ona hot cook stove.
Do not connect the cook stove to a flue thatis serving another appliance.
Do not set any materials on the cook top
that are not intended. The surface will
become very hot during operation and eventhough ignition may or may not take place
the heat will melt or burn most objects which
may in turn drip into the firebox will may
create an ignition.

Install a smoke detector.
Keep a fire extinguisher handy. We
recommend the type rated "A B C."
Dispose of ashes properly. (See page 19)

PERIODIC CHECKLISTPerform each of these tasks at the specified
intervals. (While these are to be used as a rule ofthumb, Hearthstone recommends that a qualified
service technician inspect your wood burning systemapproximately every other month during heavy use).
Every Week:
Empty ashes from the firebox and ash pan,sooner if the firebox is full.
Every Month:
Visually inspect chimney connector andchimney for creosote; clean accordingly.
o Tap the outside of the pipe to feelfor buildup of creosote. If the pipe
feels hollow, your pipe is most likely
clean and safe for use. If the pipe
feels solid or full, it probably has
accumulated creosote and should
be cleaned before further use.
Every Other Month:
A visual inspection of the chimney connector
and chimney for creosote is recommended
depending upon your use of the stove.
Check the fuel loading door seal using the"dollar bill test." (When the fire is out and thestove is cool, shut the door on a dollar bill. If
the bill pulls out without any resistance, thenyour stove’s door isn't sealed properly.) To
tighten the seal, change the door gasket.
Every Season:
Have a qualified service technician inspect yourchimney and wood burning system.
Dismantle the chimney connector and clean
it thoroughly. Replace any pieces that show
signs of rust or deterioration.
Inspect and, if necessary, clean yourchimney.
Thoroughly clean out the inside of the stove.
Inspect all door gasket material and replace
if worn, frayed, cracked or extremely hard.
Clean and inspect the oven and oven door
components.

Other safety guidelines
Keep all combustible items such as
furniture, drapes, clothing, and other items,
at least 36" (0.92 m) from the cook stove(See page 9) for more clearance to
combustibles information)

Installation
UNPACKINGIf you use a close clearance connector pipe, it
must be tested to UL standards and listed.

Hearthstone packages your Deva 100 cook
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 cook stove, unpack it
carefully, inspecting your stove and all parts fordamage. Also, make sure that all parts areincluded in the box. If any parts are damaged
or missing, please contact your dealer
immediately.

Check the listing for your pipe for actual
clearances.
The diagrams in this manual
represent typical installations, but are specific to
the Simpson Dura-Vent DVL brand. Clearances
cannot be reduced without the use of close
clearance connector pipe and/or by protecting
the surfaces per NFPA 211 standards.

CLEARANCES TO NFPA 211
PROTECTED SURFACESINSTALLING YOUR STOVE

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 forspecifications and complete details. You canobtain this information directly from NFPA.

The Deva 100 is not approved for
installation in a mobile home.
The Deva 100 Cook stove does not require theuse of additional outside air for combustion.
There is no kit available for this installation soplease keep this in mind when installing andplanning your Deva 100.

First you must decide where your stove willreside. After choosing an appropriate spot,
inspect this location to make sure that thestove will have enough clearance to
combustible materials. These combustibles
can include walls, floor, ceiling, cabinets,
fireplace, and chimney. You must carefully
consider the clearances to all of these
combustibles before actually connecting yourcook stove.
When considering theseclearances, also decide the kind of floor thestove will rest on. Depending on your floor,
you can install your stove as it is, or use a floor
protector, some types of flooring may require
additional floor protection.
Please use this section to plan how to locate
your stove.
Read this chapter to obtain a soundunderstanding of how to properly install yourstove.

HEARTH REQUIREMENTS AND FLOORPROTECTION

If venting the unit using the rear exit, floor
protection must extend 2" on either side of pipe.

Install your stove on the following:
A non-combustible floor protector that you
obtain from your dealer, or any othernoncombustible material (metal, glass, stone,
tile, etc,). A floor protector is any
noncombustible surface laid on the floor
underneath the stove that extends, 16 inches US (or 46 cm in Canada) beyond the fuelloading door and 8 inches (20 cm) beyond eachside of the cook stove. (See Figure 1) The
hearth protection for your Deva 100 must havean R-value of at least 0.89 or be a UL Listed
floor protection.

23-3/439-3/4(US)41-3/4(CAN)"

16 (US)
18 (CAN)"An example of a non-combustible floor
protector would be a hearth constructed with acontinuous layer of a listed backer board (suchas Micore, Wonder-Board or Durock) used forember protection with a tile, brick, slate, oranother noon-combustible facing.

56"

Figure 1 - Hearth Protection for top ventinstallations

For horizontal chimney connector installations, thefloor protection must be installed beneath theconnector and 2” beyond each side.
Floor protector’s come with various types of
specifications. To convert a floor protector’s
specification to an R-value, do one of the following:If the R-value is given, use that value—noconversion is needed.
If a K-factor is given with a required
thickness (T) in inches, use this formula:
R-value = 1/K x T
If a C-factor is given, use the formula:
R-value = 1/C

To determine the R-value of the proposed alternate
floor protector:

Use either the K-factor or the C-factor
formula explained above to convert
specifications not expressed as R-values.
For multiple layers of floor protectors,
simply add the R-values of each layer todetermine the overall R-value of the layers.

If the overall R-value of your setup is greater thanthe R-value of the specified floor protector, thenyour setup is acceptable.

VENTING COMPONENTS AND CONFIGURATIONCHECK THE SPECIFICATIONS FROM THE
MANUFACTURER OF YOUR CONNECTOR.

COMPONENTS OF A VENTING SYSTEM

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.

DO NOT CONNECT THIS UNIT TO A
CHIMNEY FLUE SERVING ANOTHERAPPLIANCEThe complete venting system consists ofseveral components: chimney connector, wall
thimble, wall pass-through, chimney, and liner.
It is absolutely necessary that if you install all ofthese components, they must remain within theclearances to combustibles discussed earlier toinstall your stove safely. To protect against thepossibility of a house fire, you must properly
install and constantly maintain the venting
system. Upon inspection, immediately replacerusted, cracked, or broken components.

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 woodcook stove and the connected appliance.

The chimney connector is the stovepipe from thewoodstove to the chimney.
The chimney
connector stove pipe 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.

WARNING: DO NOT CONNECT THISAPPLIANCE TO ANY AIR DISTRIBUTION
DUCT OR SYSTEM.
A liner is the UL 1777 or ULC S635 (for factorybuilt fireplace or masonry) chimney.

Double wall connector (close clearance pipe)
which must be used with a listed factory-built“Type HT" chimney and may also be used with amasonry chimney to reduce clearances, isavailable from several manufacturers, yourdealer can help you choose. Some air insulated
connector pipe models available are: Simpson
Dura Vent DVL, Metalbestos DS. The following
models have acceptable close clearance
connector pipe for the Deva 100; Security, GSW
and Ameritec.
Chimney connector shall not pass through floor
or ceiling, nor any attic or roof space, closet or
similar concealed space.
Where passage
through a wall or partition of combustible
construction is desired, the installation shallconform to NFPA 211 or CAN/CSA - B365.

You must connect your stove to a chimney
comparable to those recommended in thismanual. Do not use stovepipe as a chimney orliner system. Use stovepipe for freestanding
installations only to connect the stove to aproper chimney.

INSTALLING A VENTING SYSTEM
Stovepipe sections must be attached to thestove and to each other with the crimped end
toward the stove. If creosote builds up, thisallows the creosote to run into the stove and not
the outside of the stovepipe and onto the stove.

It is very important to follow minimum clearances
for chimney connectors to combustibles such as
walls and ceilings when installing the stove nearnon-combustible surfaces.
Typical chimney
connector clearances are outlined below. The
single wall clearances are generic; the Double
wall clearances are for Simpson Dura Vent DVL,

Secure all venting joints. Attach the stovepipe
to the stove's flue collar, with at least three
sheet metal screws. Install #10 x 1/2" (3 mm x
13 mm) sheet metal screws into the holes predrilled in the flue collar.

Hearthstone Quality Home Heating Products, Inc ®

Model 8220

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 yourchimney, as well as allowing you to easily
dismantle the stovepipe (without moving thecook stove) when you periodically inspection
the stovepipe connection and chimney.

METAL CHIMNEY

Install the stove as close as practical to thechimney,
while maintaining all proper
clearances. Install stovepipe that is as shortand as straight as possible. Horizontal runs ofstovepipe should always rise away from thestove a minimum of 1/4" per foot (21mm/m).

▌

When connecting the Deva 100 to aprefabricated metal chimney, you must follow,
precisely, the manufacturer's installation
instructions. Use only Type HT (2100 deg. F),
prefabricated metal chimneys listed per UL 103
or ULC S629 standards.
WARNING:
DO NOT CONNECT THE STOVE TO A
CHIMNEY FLUE SERVING ANOTHERAPPLIANCE.

Make sure the size of the chimney’s flue isappropriate for the Deva 100. The Deva 100
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 flue with areducer.
An oversized flue contributes tocreosote accumulation. (In this case, bigger is
NOT better.)Long runs of stovepipe to increase heatdispersal are not recommended. Using longer
lengths of stovepipe or more connecting elbows
than necessary increase the chances of draft
resistance and the accumulation of creosotebuildup.
In general, you do not need to install astovepipe damper with the Deva.
Some
installations, however, could benefit from astovepipe damper, such as a tall chimney which
can create a higher than normal draft. In suchcases, a damper can help regulate the draft.
The Deva requires a draft between 0.06" w.c.
and 0.1" w.c. For drafts above 0.1" w.c, installa stovepipe damper. Locate your local
Hearthstone dealer to purchase a draft gauge
to measure the draft of your chimney and fluesystem.

When purchasing a prefabricated chimney toinstall with your stove, be sure to also purchasefrom the same manufacturer, the wall passthrough (or ceiling support package), "T"section package, fire-stops (when needed),insulation shield, roof flashing, chimney cap,
and any other needed accessories. Follow the
manufacturer’s instructions when installing thechimney and accessories. In addition, be suretomaintainallmanufacturers’
recommendations for the proper clearances tothe chimney.
There are two ways to install a prefabricatedmetal chimney:

Remember, the NFPA has recommended,
minimum clearances for chimney connectors to
combustibles such as walls and ceilings.

An interior installation where the chimney
passes inside the residence through the ceilingand roof.

An exterior installation where the chimney
passes through the wall behind the stove thenup the outside of the residence.

Whenever possible, choose an interiorchimney. An interior chimney heats up more
quickly and retains its heat; thus promotes a
better draft and discourages the formation ofcreosote. An exterior chimney does not benefit
from the warmth of being surrounded by thebuilding, so it typically operates at lower fluetemperatures than an interior chimney. An
exterior chimney’s draft is not as strong andmayexperience
increasedcreosote
accumulation.

REVERSAL OF THE FLUE COLLAR
In order to reverse the flue collar to vent thestove straight out the back, follow these simple
steps;
1) Using a 10mm wrench, or socket.
Locate and remove the four bolts
holding the flue collar in place. Once all
four bolts are removed pull the collar
away from the stove. Inspect the gasket,
ensuring it is in place, and in working
order.

Hearthstone Quality Home Heating Products, Inc ®

Model 8220

2) Locate and remove the four bolts that
hold the block-off plate on the back of
the stove. Remove the plate.

Use the following checklist to ensure that yourmasonry chimney meets these minimum
requirements:

3) Place the flue collar on the back of thestove over the rear flue exit with thegasket side towards the stove. Rotate
the collar so the 3 chimney connector
screws are easiest to access whennecessary to install later. Replace thefour bolts using the 10mm wrench.

Chimney wall construction:
 Brick or modular block at least 4" (102 mm)
thick.
 A rubble or stone wall at least 12" (305 mm)
thick.

4) Place the cover plate over the flue exiton the top of the stove, using the same
four bolts that were removed.



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.

CONNECTION TO A MASONRY CHIMNEY
Consider two primary elements whenconnecting your stove to a masonry chimney:the chimney itself and the thimble where thestovepipe connects to the chimney. Use only
Code approved masonry chimneys with a flueliner.

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.

Before connecting to a masonry chimney, hire a
professional to examine the chimney for cracks,loose mortar, and other signs of deterioration
and blockage. If the chimney needs repair,complete the project before installing and using
your stove. Do not install your stove until thechimney is safe for use.

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

toChimneyheightrequirements:(See
Illustration)
 At least 3 feet (0.9 m) higher than thehighest part of the roof opening throughwhich it passes.
 At least 2 feet (0.6 m) higher than any partof the roof within 10 feet (3 m) measured
horizontally from the top of the chimney.

Make sure the chimney’s cleanout is complete
and working properly. To avoid a loss of draft,the cleanout must close off completely. If
allowed to cool, your stove will perform poorly
and creosote will build up in the chimney.
Make sure the size of the chimney’s flue isappropriate for this stove and that it is not toolarge. 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 theaccumulation of creosote.

This stove requires a minimum chimney heightof 13 feet (4 m). The maximum allowablechimneyheight
is
30
feet
(9
m).

bypass system. This is the handle at the top
center of your stove that pushes and pulls inand out. To open the bypass, pull the handle
out. This opens a “bypass” channel that allows
the hot gases to heat up the chimney quicker.
This bypass allows for a direct outlet of the fluegases and smoke. With the bypass closed thegases follow the normal route around the ovenand then out. You should keep the bypass
open until your flue has established a draft.
Once a draft has been established push thebypass closed. This will ensure the mostefficient use of your Deva.
*Burning the Deva 100 with the bypass open
will not allow the oven to reach maximum
temperatures.

Please read this entire chapter before lighting
your first fire. It explains the controls andfeatures of your wood stove, how to choose
firewood, and how to use your stove on a daily
basis.

FUEL LOADING DOOR HANDLE: The fuelloading door allows you to load wood into yourstove. To open the door, lift the handle to the 9o’clock position and pull the door. To latch thedoor, lower the handle to the 6 o’clock position.
Pull gently on the door to make sure it isproperly latched.

CONTROLS AND FEATURES
Before lighting any fires, become familiar withthe location and operation of your stove'scontrols and features and learn how to use
them. For your own safety, do not modify
these features in any way.

FLUE BYPASS SYSTEM: When starting a firein a cold Deva 100 you will need to use the flue

PRIMARY AIR CONTROL: This feature islocated on the lower portion of the ash door of
the stove. The primary air control allows you toregulate the amount of air entering the firebox.
Generally speaking, the more air allowed into
the firebox, the faster and hotter the rate ofburn; conversely, less air creates a slower burn.
Push the lever to the left to open the primary aircontrol; push the lever to the right of the stove
to close the primary air control.

while hardwoods burn longer and produce morecoals. Density and moisture content are two
critical factors to consider when purchasing
wood for your stove.
The following is a list of wood species and theirrelative BTU (British Thermal Unit) content.
The higher the BTU the longer the burn.
Firewood with higher BTUs is generally
considered more ideal for a wood stove.

ASH PAN: The ash pan is located under thefirebox door. The ash pan collects burned ash
from a fire and allows you to conveniently
remove the ash from your wood stove. The ash
pan is easy to remove. Sift the ashes acrossthe grate and into the ash pan, and then rotate
the ash door handle to the 9:00 o’clock and pull
to open. Remove the ash pan by grabbing thehandle and sliding it out carefully. After you
have disposed of the ashes, push the ash pan
all the way into the stove and close the ashdoor by turning the handle to the 6 o’clock
position.

HIGH: Apple, Black Birch, Hickory, Locust,White Oak, Black Beech, Mesquite
MEDIUM HIGH: White Ash, Beech, Yellow
Birch, Sugar Maple, Red Oak
MEDIUM LOW: Black Ash, White Birch, Grey
Birch, Elm, Norway Pine, Pitch Pine, Black
Cherry, Soft Maple, Tamarack
LOW: White Pine, White Cedar, Balsam Fir,
Spruce, Aspen, Basswood, Butternut, Hemlock

Remove ashes when the stove is cold. If theash pan is warm, use protective fireplace
gloves.
Exercise extreme caution whenhandling, storing or disposing of ashes.

Moisture content also plays a key role in theperformance of your stove. Wood freshly cut
from a living tree (green wood) contains a great
deal of moisture. As you might expect, green
wood has difficulty burning and should beseasoned before using it in your cook stove. To
properly season green wood, it should be split,
stacked and allowed to air dry for a period of
one year.

CHOOSING FIREWOOD
Your Deva 100 cook stove is designed to only
burn firewood-also known as cordwood.
▌

CAUTION:

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 thewoodpile trap moisture and prevent the woodfrom drying. As for stacking, an old Vermonter
said, "The spaces between the logs should belarge enough for a mouse to get through, but
not for the cat that's chasing it."

DO NOT USE CHEMICALS OR
FLAMMABLE FLUIDS SUCH AS
GASOLINE, NAPHTHA, KEROSENE,
CHARCOAL LIGHTER FLUID OR
ENGINE OIL TO START A FIRE. DO
NOT USE CHARCOAL, PELLETS,
COAL, ARTIFICIAL LOGS OR ANYOTHER MATERIALS AS FUEL; THEYARE NOT SAFE. DO NOT BURNGARBAGE.

Firewood should not be stored within thestove's specified clearances to combustible
materials.

The quality of your firewood affects heat output,
duration of burn and performance of your stove.

BUILDING YOUR FIRST FIRE

5. Close the door and allow the fire toburn.

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

6. Once the kindling is burning, open thedoor and add logs, small at first, to build
the fire up. Otherwise, keep the fuelloading door and ash door closed while
the stove is in use.

When you light your first fires, the wood stove
will emit some smoke and fumes. This isnormal “off-gassing” of the paints and oils used
when manufacturing the wood stove. If you findit necessary, open a few windows to vent yourroom. The smoke and fumes will usuallysubside after 10 to 20 minutes of operation.
The odor and smoke will end once the stove is“cured”.

Do not open the fuel loading
door with the bypass closed!
7. Close the bypass system by pushing thehandle all the way in.

The first fires may produce other odors from
impurities that exist in the area immediately
surrounding the stove.
Some of these
impurities can be cleaning solvents, paintsolvents, cigarettes, smoke, pet hair, dust,
adhesives, a new carpet, and new textiles.
These odors will dissipate over time. You canalleviate these odors by opening a few windowsor otherwise creating additional ventilation
around your stove.

8. Once the fire is burning well, use theprimary air control to regulate thedesired rate of burn. Pushing the leverto the left of the stove opens the
PRIMARY AIR CONTROL for a highrate of burn or pushing it to the right ofthe stove for a low rate of burn.
9. The flue bypass is used to control thecook top and oven temperature.

BUILDING A FIRE

Note: When opening the door to reload
or re-arrange 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 toclear of smoke before the door is opened
fully. You must open the flue bypass
system prior to opening your fuelloading door. Also, reloading on a bed ofhot, red coals reduces smoking time andwill bring fresh fuel up to a hightemperature rapidly.

1. Open the door and place five or six
double sheets of tightly twisted
newspaper in the center of the firebox.
Arrange kindling in a crisscross patternover the newspaper. Kindling should beapproximately ten pieces, 1/2" (13 mm)
in diameter and 10" to 17" (254 to 431mm) long.
2. Open the flue bypass system by pullingthe handle out completely. (as describedon page 17)
3. Fully open the primary air control bypushing the lever toward the left of thestove.
4. Light the paper under the kindling.
Leave the door slightly ajar momentarily
until the kindling has started to burn anddraft begins to pull.

suspect that your stove is over-firing, contact
your dealer immediately. Damage done byover-firing is not covered by your warranty.
Results of over-firing can include: warped orburned out internal parts, cracked refractory,
discolored or warped external parts, anddamaged enamel.

BURN RATEHIGH BURN: Fully load the firebox with wood
on a bed of hot coals or on an actively flaming
fire and fully open the primary air control. Ahigh burn rate is recommended once or twice a
day to fully heat the stovepipe 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
mid-range setting appropriate for the heatingneeds 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 should be removed when the stove iscold. Use protective fireplace gloves when thepan is warm. Exercise extreme caution whenhandling, storing or disposing of ashes.

LOW BURN: Close the primary air control for a
low burn rate. A low burn rate over extended
periods of time is not advisable as it may
promote the accumulation of creosote. The
venting system should be inspected frequently
if low burn rates are maintained consistently.

To remove ashes from the firebox, sift theashes across the ash grate using a poker orother suitable implement. Remove the ashes
by pulling the handle on the ash pan and sliding
it carefully out. Dump the ashes as described
below. Re-insert the ash pan by pushing it in all
the way. Be sure that the ash pan has been
pushed firmly into place. Alternately, the ashes
can be removed with a shovel through the fuelloading door.

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.
Symptoms of over-firing include short burntimes, 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 the ashes to cool. Do not place theash disposal container on a combustible
surface or vinyl flooring, as the container will behot!

Over-firing can be caused by excessive draft,inappropriate fuel, and operator error. Correct
an over-fire situation as follows:
EXCESSIVE DRAFT: Contact your dealer tohave a draft reading taken. Any draft in excess
of 0.1 wc requires a damper in the stovepipe.
Some installations may require more than one
damper.
INAPPROPRIATE FUEL: Do not burn coal, kiln
dried lumber, wax logs or anything other thannatural cordwood.
OPERATOR ERROR: Make sure all thegaskets are in good condition. Replace wornout or compressed gaskets. Do not burn thestove with the fuel loading door, or ash pan
door in the open position.

Pending disposal, place the closed ash
container on a noncombustible floor or on the
ground, well away from all combustible
materials. Ashes should be retained in theclosed container until all cinders havethoroughly cooled.
Ashes should NEVER be placed in wooden or
plastic containers, 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.

Monitoring the temperature is the best way todetermine that the stove is over-firing. If you

be a certified sweep!).

CREOSOTE FORMATION AND NEED FORREMOVALGASKETS
Gasket material should normally be replaced
every two to three seasons, depending on stoveuse. If the door seal is loose, a new gasket willassure a tight seal and improved stove
performance. Contact your dealer for a gasket
kit, which includes instructions, and gaskets foryour stove.

When wood is burned slowly, 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 anextremely hot fire, which may damage thechimney or even destroy the house.

To replace the fuel loading door gasket, firstremove the old gaskets with a utility or putty
knife. Clean all gasket channels with a wirebrush. Apply gasket cement to the 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.

To prevent the buildup of creosote:
1. Burn the stove with the primary aircontrol fully open and the flue bypass
open for 30 minutes daily to burn out
creosote deposits from within the stove
and the venting system.

We require the use of the following gaskets:
FUEL LOADING DOOR:
40"
(102
cm)
Length, 1/4" Diameter, Low Density Black Rope

2. After reloading with wood, burn thestove with the primary air control fully
open for 20 to 30 minutes. This mannerof operation ensures early engagementof the secondary combustion system
which, when engaged, minimizes
creosote buildup in the chimney.

The stovepipe connector and chimney should
be inspected regularly during the heating
season to determine if a creosote build-up has
occurred. If a creosote residue greater than
1/4" (6 mm) has accumulated, it should be
removed to reduce the risk of a chimney fire.

GLASS
Do not operate the stove with a broken door
glass. Do not abuse the fuel loading door by
striking or slamming it.

The venting system must be inspected at thestove connection and at the chimney top.
Cooler surfaces tend to build creosote deposits
quicker, so it is important to check the chimney
at the top (where it is coolest) as well as fromthe bottom near the stove.

When necessary, the glass can be cleaned withlow alkaline content commercial stove glasscleaners, which are available from your local
dealer. Never attempt to clean the glass while
the fire is burning or the glass is hot. Following
the instructions provided with the cleaner canclean most deposits.
To clean heavier
deposits, remove the door from the cook stoveand lay the it face down on a workbench or

Accumulated creosote should be removed witha cleaning brush specifically designed for thetype of chimney in use. A certified chimney
sweep should be used to perform this service.

table. Apply the cleaner to the glass and allow
it to set for a few minutes. By laying the door
flat, it will allow the cleaner to penetrate rather
than running off the surface of the glass. Wipethe cleaner off with a soft cloth.
Important: scratching or etching theglass will weaken the integrity of theglass. Do not use a razor blade, steel
wool, or any other abrasive material toclean the glass. Use low alkaline content
cleaners only.

MAINTENANCE OF THE GLASS COOK TOP
Be sure utensils have no rough spots to scratch
the surface. Be sure the surface is clean before
the fire is started. Avoid spills and boil-overs byturning down heat to lowest possible setting forcooking task, and by using a large enough pan.
Wipe up wet spots promptly, being careful toavoid steam burns. Don't cook with foil on theglass cook top. It could be damaged by foil
melting onto it. Cover pans to prevent spatters.

The fuel loading door glass is a ceramic, shockresistant glass, made specifically for use inwood-burning stoves.
Do not use any
replacement glass other than the ceramic glass
manufactured and supplied for use in this cook
stove. Replacement glass is available throughyour local dealer.
The fuel loading door glass should be replaced
immediately if broken.
Contact your local
dealer for replacement glass, which isaccompanied with instructions and everythingneeded for the repair. If you replace the glass
yourself, wear work gloves and safety glasses.

CLEANING OF THE GLASS COOK TOP
Special care should be taken when removing
hot substances. Turn off all surface units
affected by the spillover and remove the hotpans. Wearing an oven mitt to hold the scraper,
scrape the spill to a cool area of the cook top
and use a paper towel to remove any excess.
Do not continue to use the soiled area until all
the spillover has been removed. A couple ofrecommended cook top cleaners are:

CAST IRON
Exterior cast iron parts are porcelainized withan enamel finish. Use a damp sponge to wipe
clean. Dry the cast iron thoroughly to prevent
rusting.

The procedure for the fuel loading door glass
and glass gasket replacement is as follows:
1. Remove the top hinge straight up andaway from the stove.
2. Remove the door by pulling it up andaway from the stove.
2. Place the door face down on a flat,smooth surface.
3. Apply penetrating oil to the 2 screws in
the retention frame. Remove the 2screws. Separate the cast iron window
frame from the door.

Enamel castings can be cleaned with astandard glass cleaner. With time and use, avery fine, subtle network of crazed lines may
appear seemingly beneath the surface of theenamel.
Crazing is a natural predictableprocess and does not represent a flaw.

TROUBLESHOOTING
Most are correctable and generally require only
a minor adjustment of the stove, installation, or
operating technique. In cases where weather
conditions
dramaticallyaffectstove
performance, the problems are typicallytemporary and solve themselves once theweather changes.

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 theplacement of other objects in the vicinity of the
proposed chimney location.

One common cause of poor performance is anoversized chimney flue. Oversized chimney
flues result in decreased pressure, which
prevents the smoke from rising out thechimney. Oversized flues are also more difficult
to heat effectively, especially when burning ahigh efficiency stove. Cool flue temperatures
inhibit the establishment of a strong draft (andencourage the accumulation of creosote). The
lack of a strong draft will cause the fire to die
down and may even force the smoke to pourinto the room.
If your chimney is the proper size and a strong
draft is not easily established, there is thepossibility of the chimney being too cold.
Again, hot chimneys promote a stronger draft.

WIND VELOCITY: Generally, the stronger andsteadier a wind, the stronger (better) the draft.
However, "gusty" wind conditions may cause
erratic downdrafts.
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 theweather changes.
BRISKNESS OF FIRE: The hotter the fire inyour stove, the hotter your chimney and,
therefore, the stronger the draft.
BREAKS IN THE VENTING SYSTEM: An
unsealed clean-out door at the bottom of thechimney, leaky stovepipe joints, a poor
stovepipe-to-thimble connection, or a leaky
chimney may cause inadequate draft.

Other draft guidelines are as follows:
AN "AIRTIGHT" HOUSE: If your home issuper-insulated or especially well sealed, the(infiltration) air supply to the interior of thehouse may be inadequate. This phenomenonof air starvation within the building can beexacerbated if exhaust fans, such as clothes
dryers, bathroom fans or cook-stove exhaust
fans, are in operation within the home. The
need for additional air may be accommodated

SEASONAL FACTORS: Early fall and latespring are generally difficult seasons in which toestablish proper drafts. The colder the outsideair (relative to room temperatures), the stronger
the draft.
