Congratulations on the purchase of your new
Morsø stove!
Morsø, which is the largest supplier for the Dan-
ish market, has manufactured stoves of the highest
quality since1853. By following the instructions over-
leaf, we are sure that you will enjoy the use and the
benets of your stove for many years to come.
Read this entire manual before you install and use your new room heater. If this room
heater is not properly installed, a house re may result. To reduce the risk of re, follow
the installation instructions. Failure to follow instructions may result in property dam-
age, bodily injury, or even death.
Contact local building ocials about restrictions and installation inspectionrequirements
in your area.

Optional Accessories
A wide range of accessories (such as handling gloves, reside tools, glass cleaner and heat-
proof paint) are available for use with your Morsø stove. They help with day-to-day running
and maintenance. Contact your Morsø dealer for more information.
The Morsø 3112 & 3142 meets the U.S. Environmental Protection Agency’s emission limits
for wood heaters sold on or after July 1, 1990.
The Morsø 3112 & 3142 have been tested by OMNI-Test Laboratories, Inc. The test standards
are ANSI/UL-1482 for the United States and ULC S627 for Canada.
The stove is listed for burning wood only. Do not burn other fuels.
Under specic test conditions this heater has been shown to deliver heat at rates ranging
from 9,300 to 28,500 Btu´s.
Cast iron
Cast iron is a live material. There are no two ovens that are identical. This is partly due to the
tolerances of the casting process, partly because the ovens are a work of craftsmanship.
Minor unevennesses may also occur in the cast iron surface.

DK ENG
Installation of woodburning stoves must be safe and legal.
If your Morsø stove is not installed correctly, it may cause a house re. To reduce the risk
of re, the installation instructions must be followed carefully. Contact the local building
ocials about restrictions and installation inspection in your area.
Before you start installing your stove, make sure that:
- The stove and chimney connection are placed far enough from combustible materials to
meet all clearance requirements.
- The oor protection must be adequate and must be made correctly according to the re-
quirements.
All neccessary approvals are needed from the local building ocials.
The data plate, which is located on the back of the stove, provides information regarding safety
testing information, name of certied testing laboratory, and installation requirements.
Installation requirements vary in dierent districts, and the local building ocials have the nal
authorization to approve your installation. You should discuss the installation with them before
beginning. Please ask your dealer for further information.
Do not connect to any air distribution duct or system.
Important: If the installation instructions are not followed carefully, it may cause dan-
gerous situations like chimney - and house res. Follow the instructions carefully and
do not deviate from them as it may cause injuries to people or property.
1.1 Checking loose parts in the stove
After unpacking, check that the center grate (in the centre of the re bed) and the re bricks
are rmly in position and have not shifted in transit. Check also that the air control works freely.
The stove is heavy and therefore it is strongly recommended that when lifting, it is under-
taken by two people.
Fitting instructions for Legs
Morsø 3112: After removing the outer packaging, atten it and lay onto the oor close to the
stove; this can then act as protective work surface during the assembly process.
Next, remove the legs and bolts from inside the stove. Gently lay the stove onto its back and
unscrew it from the wooden pallet. Using the bolts supplied, now screw the legs into position
on the underside of the base. The stove should now be lifted and moved into the upright posi-
tion, avoiding excess load on the back legs.
Morsø 3142: After removing the outer packaging, the stove should now be lifted and moved
into the position.

How to position the bae and access bae
Make sure that the upper bae plate (2) is located into its correct
position. It should be placed on top of the rear (xed) bae sec-
tion and secured into position against the 2 upstanding cast lugs.
Note: The access bae (3) must always be tted when the stove
is in use, as it not only assists the combustion process, but also
gives essential protection to the stove’s top plate.
Standard Accessories
Poker, ceramic ue connection gasket and riddling tool are standard
accessories, and can usually be found in the ashpan or rebox area.
1.2 The chimney / ue system
Note that the ue system must be independently secured and must
not rely on the stove for support.
The stove must not be connected to a chimney ue serving any other appliance.
(Several ues may run up a single chimney stack; use one ueway per appliance).
Use a residential type masonry or listed type HT factory-built chimney.
High Temperature (H.T.) Chimney Standard UL-103-1985 (2100º F.) for the USA, and High
Temperature (650ºC) Standard ULC S-629 for Canada.
The internal dimensions of the chimney connector and chimney must not be less than 6 inch-
es diameter (or equivalent cross section), and should not be signicantly larger than this. Too
large a section will tend to allow the ue gases to cool excessively, causing sluggishness or
unpredictability in the stove’s performance.
We recommend the length of the chimney system should be at least 16 feet (not required)
above the stove in normal domestic situations, measured from the ue collar to the top of
the chimney. Local conditions like for example - roof constructions, large trees nearby and
high altitude, may inuence the chimney draft and height. Therefore, contact the local pro-
fessional chimney sweep or your Morsø dealer.

1.3 Flue Connection
The stove is supplied from the factory with a ue collar tted to the top plate and a round
blanking plate blocking o the rear ue exit (behind the rear shield plate).
Use a 24 MSG black or blue chimney connector or listed double wall chimney connector. Re-
fer to local codes and the chimney manufacturer’s instructions for precautions required for
passing a chimney through a combustible wall or ceiling. Remember to secure the chimney
connector with a minimum of three screws to the product and to each adjoining section.
Where a rear ue installation is required, simply knock out the top steel plate in the rear heat
convection panel. This is best done by applying gentle hammer taps immediately onto the small
”bridges” in the circular cut-outs. Once the knock-outs have been removed unbolt the cast iron
blanking plate and install it into the top of the stove. The ue collar can then be bolted over the
rear ue outlet using the bolts and clamps provided.
The cast iron blanking plate can also function as an extra clean-out access whilst perform-
ing the annual cleaning service of the stove and chimney.
Wear gloves and protective eyewear when drilling, cutting or joining sections of chim-
ney connector.
1.4 Connection to the existing chimney
A chimney connector is the double-wall or single-wall pipe that connects the stove to the chim-
ney. The chimney itself is the masonry or prefabricated structure that encloses the ue. Chim-
ney connectors are used only to connect the stove to the chimney.
Double-wall connectors must be tested and listed for use with solid-fuel burning applianc-
es. Single-wall connectors should be made of 24 gauge or heavier gauge steel. Do not use
galvanized connector; it cannot withstand the high-temperatures that smoke and exhaust
gases can reach, and may release toxic furnes under high heat. The connector must be 6
inches (150mm) in diameter.
If possible, do not pass the chimney connector through a combustible wall or ceiling.
If passage through a combustible wall is unavoidable, refer to the sections on Wall Pass-
Throughs. Do not pass the connector through an attic, a closet or similar concealed space
when installing the chimney connectors.
It is important to keep the ue gases moving smoothly in the right direction. Do not vent
into a large void at this location; rather form one continuous section all the way up. Use mild
bends (e.g. 45º vs. 90º) rather than sharp angles where a change of direction is required. All
parts of the venting must be accessible for cleaning purposes.
In horizontal runs of chimney, maintain a distance of 18 inches from the ceiling. Keep it as
short and direct as possible, with no more than two 90 degree turns. Slope horizontal runs
of connector upward 1/4 inch per foot (20 mm per metre) going from the stove toward the
chimney. The recommended maximum length of a horizontal run is 3 feet (1 metre), and the
total length should be no longer than 8 feet (2.5 metres).
Information on assembling and installing connectors is provided by the manufacturer’s in-
structions exactly as you assemble the connector and attach it to the stove and chimney.
Be sure the installed stove and chimney connector are correct distances from near by
combustible materials. See the clearance paragraph page 8.

DK ENG
1.5 Positioning the stove
Distance to walls and lintel
When the stove is positioned near combustible materials, observe all current local and na-
tional building regulations with regards to clearances. Whatever regulations apply to your
area, do not in any case install the stove within 8 inches of combustible materials around the
sides or 16 inches above the top of the stove. These distances may need to be increased if
the materials are sensitive to heat. Note also that wall paper and other decorative materials
may become detached with the eects of heat and care should be taken to ensure that they
do not fall towards the stove in such an event.
When the stove is positioned near non-combustible materials, a gap of 4 inches or more is
recommended for cleaning purposes and to ensure that heat circulates around the stove
and out into the room.

Combustible oor must be protected with non-combustible material beneath the unit and extend-
ing 16-in (450-mm Canada) to the front and 6-in (200-mm Canada) beyond each side of the fuel/
ash removal opening. For horizontal cimney connectors, non-combustible material must be place
beneath the connector and 2-in to each side.
You must ensure that the oor can hold the weight of the stove comfortably.
If using rear exit the oor protection must extend beneath the chimney connector and 2-in
beyond each side.
Distance to furniture
The recommended minimum dis-
tance from stove to furniture is 30
inches. Note that some furniture is
more easily aected by heat and
may need to be moved to a greater
distance. This is your responsibility.
In addition other combustible materials, away from the stove. In general, a distance of 30
inches must be maintained between the stove and moveable combustible item such as dry-
ing clothes, newspapers, rewood etc.

1.6 Mobile Home Installation
The Morsø 3112 & 3142 can be installed in a mobile home if equipped with an outside com-
bustion air kit, a terminal cap with a spark arrestor, and if it meets the following installation
requirements:
- The stove must be secured to the mobile home structure by bolting through the hearth
pad and into ooring.
- The stove must be installed with a listed Type HT chimney connector, HT Chimney, and
terminal cap with spark arrestor. Never use a single wall connector (stovepipe) in a mo-
bile home installation.
- Floor protection requirements in section 1.5 must be followed precisely.
- Follow the chimney and chimney connector manufacturer’s instructions when installing
the ue system for use in a mobile home.
- Outside air kit should be installed according to installation guide in the kit.
- Intake air piping can be installed through the oor into a vented crawl space or through
the wall of the residence to obtain outside air.
- Install in accordance with 24 CFR, Part 3280 (HUD).
- NOTE: Top sections of chimney must be removable to allow maximum clearance of 13.5’
from ground level for transportation purposes.
WARNING:
NEVER DRAW COMBUSTION AIR FROM A WALL,
FLOOR OR CEILING CAVITY OR FROM ANY EN-
CLOSED SPACE SUCH AS AN ATTIC OR GARAGE.
DO NOT INSTALL IN A SLEEPING ROOM.
CAUTION:
THE STRUCTURAL INTEGRITY OF THE MO-
BILE HOME FLOOR, WALL, AND CEILING/
ROOF MUST BE MAINTAINED (I.E., DO NOT
CUT THROUGH FLOOR JOIST, WALL STUD,
CEILING TRUSS, ETC.) DO NOT USE A GRATE
TO ELEVATE FIRE - BUID FIRE DIRECTLY ON
HEARTH.
Note:
Acid Protection
If acid-washing the masonry around the stove, protect the stove surface with an acid-proof
cover.
Fresh Air Inlet
Unless there is deemed to be sucient ambient leakage of air into the room via doorways, windows
and the like, a dedicated fresh air inlet will be needed. This inlet should have 2 square inches (1250
square mm) of free air space. This is particularly importAnt where the room is well sealed, or where
an extractor hood or ventilation system disturbs the natural air pressure. Such an inlet should not
be on a wall that is usually subject to negative pressure from normal wind pattern. Avoid placing the
inlet directly across the room from the stove, thus causing a cold air draft.

2.0 Operation
2.1 Before you start ring
For use with solid wood fuel only. Do not overre, if heater or chimney connector glows you
are overring. Inspect and clean chimney frequently. Under certain conditions of use creosote
buildup may occur rapidly. Because of risk of smoke and ame spillage, operate only with door
fully closed.
Caution:
Hot while in operation. Keep children, clothing and furniture away. Contact may cause
skin burns.
Do not use chemicals or uids to start the re.
Do not burn garbage or ammable uids.
Do not use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter or uid or simi-
lar liquids to start or freshen up a re in this heater. Keep all such liquids away from the
heater while it is in use.
Choosing your fuel
All types of natural wood can be burned on your stove, but they must be well-seasoned and
dry. Once the wood is cut to length, it should be split down middle - to suit the dimensions
given below - to allow moisture to evaporate.
Cut the wood to a length of max 12 inches (30 cm) and approx. 3 to 3.5 inches (7-8 cm) in
section. If you can weigh your wood, aim for around 2 lbs. For correct combustion and heat
output, wood fuel should contain no more than 20% moisture; this can easily be checked by
using the Morsø Moisture Meter (part # 62929900).
To naturally season wood fuel, stack and store it under cover in an airy location where fresh air
can move through each piece. Some soft woods may take as little as one good summer to sea-
son whereas harder woods such as oak, maple, and elm may require seasoning up to 18 months.
Avoid overly dry wood that is gray in color as under certain conditions it can cause performance
problems, such as back-pung and sluggishness. Well seasoned wood will be light to hold and
will show signs of cracking from the center-out in the ends. If your wood spits or sizzles when
burnt, and your stove’s door glass persistently mists up, your wood is not properly seasoned.
Never use drift wood (from the sea), whose salt content may cause corrosion, nor construction
wood that may have been impregnated with chemicals.
Starting the rst re:
The initial re should be small, so that the stove paint can cure and the main plates of
the stove can settle into position. Some fumes will be given o by the paint. Ventilate
the room during this phase.
The setting of the valve, lighting techniques and loading intervals will depend on chim-
ney draft, the fuel used, the heat required and so on. Some basic techniques are out-
lined below.

12
DK ENG
In principle
Your stove is tted with Primary and Secondary air inlets.
Primary Air is controlled using the lever situated under the ash lip of the stove. Moving the con-
trol lever into a downward position will open the air inlet and will allow a supply of preheated
air to enter the rebox via the ‘airwash’ system situated inside the stove and the above glass.
Secondary Air is delivered to the rebox using the specially designed bae at the back of the re-
box. The secondary air is injected into the ue gases both above and in front of the re resulting in
a cleaner, more ecient combustion process. The supply of secondary air is xed open and is not
adjustable. The lower air controler on the door is xed, and only for decoration purposes.
For extra safety, your stove has been tted with a removable handle. When not in use the
handle can be stored using the lug behind the right leg of the stove.
2.2 Lighting and loading intervals
When rst lighting the stove, a large volume of air is needed. When the stove is cold, you
should leave the door open an inch or two for the rst few minutes and open the primary air
supply completely. While the door is open, do not leave the stove unattended.
To form a reasonable bed of ash on the oor of the stove, you should use 5-6 inches thick-
ness (2-4 pound) of dry kindling at the initial lighting. Always maintain a 1-1,5 inch (2-3 cm)
layer of ash on the oor of the combustion chamber at all other times.
1. The air supply must be fully open.
2. Light the re. An ember bed will quickly be formed by light-
ing with relighters, Morsø kindling bags or 7-10 pieces of twist-
ed paper under the dry kindling wood (see above).
3. After lighting, partially close the door, leaving it open an
inch or two to allow in plenty of combustion air.

13
4. When the chimney is warmed through after 5-10 min-
utes, the door should be closed. A suitable ember bed will
be formed after a further 15-20 minutes.
5. When ready to reload, use a poker to spread the ember
across the rebox oor, bringing plenty towards the front
of the stove.
6. Lay three pieces of wood (see dimensions above) onto
the embers. Leave half an inch (1 cm) or more between
each piece. Place the ends of your logs towards the open-
ing, but not too close to the front.
7. Close the door. Leave the primary air supply fully open.
8. After a few minutes, and adjust the primary air supply
to suit your heating requirements.
9. Anticipate each refueling, remembering to add a modest
layer of wood while there are still plenty of live embers, Re-
peat steps 5-8.

14
DK ENG
Do not for any reason attempt to increase the ring of your heater by altering the air
control adjustment range outlined in these directions.
Warning: Fireplace stoves must never be left unattended with doors open.
If the door is left partly open, gas and ame may be drawn out of the replace stove open-
ing, creating risks from both re and smoke. We recommend that you t a smoke detec-
tor in the room where the stove is installed.
DO NOT OVERFIRE THIS HEATER. Overring may cause a house re, or can result in per-
manent damage to the stove. If any part of the stove glows, you are overring.
The maximum recommended weight of wood fuel per load is 2.5 kg/h/5.5Ibs (approx 3 split
logs).
Under normal ring, the average ue temperature in the stove pipe, measured 20 cm above
the stove, is approx. 300° C (550°F). The maximum ue temperature in the stove pipe must
not exceed 450° C (750°F). If the ue temperature exceeds 450°C (750°F), it is considered
as over ring and may cause premature wear and tear of the stove.
To help gauge the correct running temperature of your stove, we recommend you use the Morsø
Flue Gas Thermometer (part # 62901200). The Flue Gas Thermometer magnetically attaches onto
the stove pipe approx 20 cm (8”) above the stove’s top plate and measures the surface temperature
of the stove pipe. Please see your authorized Morsø Dealer for availability.
Draft conditions
If smoke or fumes come out of your stove when lightning up and reloading, or if the re simply
will not respond, a poor draft is almost certainly to blame. (In a very few cases, there may be
insucient fresh air getting into the room - see installation advice above). Take advice from
your stove supplier on how best to upgrade your ue system to improve draft.
Rules of woodburning
If you want less heat, put fewer logs on the stove and reduce the amount of air. It is still impor-
tant to maintain a good layer of embers.
Less heat - less wood - less air
Greater heat - more wood - more air
Soot deposits will settle on the glass if the stove is run too slowly or if your wood is not well
seasoned.

15
3.0 Maintenance
When perfoming maintenance on your stove, always protect yourself, using safety gog-
gles and gloves
3.1 Exterior Maintenance
The stove surface is painted with heat-resistant Senotherm paint. It is best kept clean by
vacuuming with a soft brush attachment or by wiping with a lint-free cloth.
Over a period of time, the painted surface may become slightly grey. A can of Morsø touch-up
spray paint should be available from your stove supplier. This can be applied - in accordance with
the instructions - in just a few minutes. When rst ring after touching up, the stove will give o
a slight smell as the paint cures. Make sure to ventilate the room well during this phase.
3.2 Internal maintenance
Glass
If the stove is generally run at the correct temperatures, there should be little or no dirt on
the glass. If dirt does settle during lighting, most will burn o as temperatures increase.For
heavier deposits that will not burn o, use Morsø glass cleaner, applied when the glass is
cold, in accordance with the instructions. Never use abrasive cleaners on the glass surface.
Reasons for dirty glass
- Fuel too wet
- Logs too large or not split
- Combustion temperatures too low
Replace broken glass immediately.
Do not operate your stove if the glass in the door is damaged.
If you need to replace the glass, it should be replaced with the high temperature ceramic
class supplied by Morsø, contact your Morsø dealer.
Installing the glass
Never install the glass when the stove is in function.
Ceramic glass replacement
Ceramic glass cannot be recycled because it has a
higher melting point that ordinary glass. If ceramic
glass is mixed with ordinary glass, the raw material is
spoiled, and the reclaiming process may be halted.
Take care that the ovenproof glass does not end up
among ordinary recycled waste. That will be a great
benet to the environment.
Note: Should be handed in to a recycling station
as ceramic glass.

1. Lift the door o its hinges an place face-down on a sheet of cardboards or other non abrasieve
fabric. The door is removed by loosening the 2 screws with a hexagon box wrench by the hinges.
2. Unscrew the bolts that secure the glass. (In the event that a bolt sheers o when being
unscrewed, remove the remaining body of the bolt by drilling down its cnetre with 1/8
inch high speed steel drill bit. Smaller drill bits may be successful, but do not use a lager
bit. Make sure the bit stays away from the edges of the bolt - this may damage the thread
in the cast iron).
3. Remove the old ceramic gaskets and clean up the surface underneath with wire wool or
emery paper to remove loose particles.
4. Place the new gasket material in position around the perimeter of the window area, mak-
ing sure to pinch them to the length in such a way that they make a continuous seal. Leave
no gaps.
5. Place the new glass in position on the strips and screw home the fresh bolts and tting
by hand.
6. Finally, give each of the bolts an extra half turn or so. The glass should held tight enough
by that cleaning will not dislodge it. Do not over-tighten the bolts as this may put exces-
sive pressure on the glass, resulting in cracking - important!
To reduce the risk of breaking the glass, avoid striking the glass or slamming the door.
Internal service parts
The ame-path equipment - consisting of the ashpan, grate, rebricks, glass, bae and ue
collar - are subject to the extremes of heat produced by the re. From time to time, one or
other of these parts may need replacing as a matter of routine maintenance.
NOTE: The ame-path equipment, the ceramic rope and the paint nish are not covered
by guarantee.
All of these service parts can be bought from your Morsø dealer, and we recommend that
damaged parts are replaced as soon as possible to avoid collateral damage.
The grate may be replaced by lifting it by its left hand edge and twisting it backwards. Dis-
locate the riddling arm from the grate by feel from beneath the oor of the rebox. If you
nd this dicult for any reason, raising the rectangular grate surround casting may help.
Should the bae be distorted by an overre, the stove will still function, although its eciency
may be compromised. Replace it as soon as possible. The rear casing is removed (four bolts).
Remove these and withdraw the bae from the rebox (this may be easier if the rebricks are
rst removed).
Before replacing the bae, scrape out the old re furnace and replace with new to make
an eective seal.
Reasons for fast internal wear and tear
Persistent heavy ring
Soot and ashes left to accumulate

17
Ceramic Gasket
The gasket around the perimeter of the door may harden over a period of time. It should be
replaced if it becomes dicult to close the door or if air starts to leak in around the perim-
eter of the door, causing the re to become a little less controllable. A Morsø rope gasket
kit is available from your stove supplier.
3.3 Cleaning the Stove and the Flue
Check for soot above the bae plate and around the ue outlet every month or so to start
with. If the stove suddenly becomes sluggish, check for a soot fall around the ue collar or
in the ue/chimney. - at least once a year. Inspect every month.
Clean the ue/chimney - all the way from the stove to the ue terminal point above the house.
A good routine is to clean the ue after each heating season in any case, and inspect prior
to the season to ensure that bird’s nests or other blockages have not ocurred during the
o season.
Ash disposal
Empty the ashpan on a daily basis or as needed. Ash allowed to build up towards the under-
side of the grate will trap heat and could cause premature failure of the grate.
Empty the ashpan according to this procedure:
When the door is closed, the grate can be operated by means of the riddling bar. Open the
front door, and use a shovel or poker to stir excess ash through the ash slots in the grate
down into the ash pan. Remove the ash pan, making sure to keep it level.
Dispose the ash in a metal container with a tight tting lid.
The closed container of ashes should be placed on a noncombustible oor or on the ground,
well away from all combustible materials, pending nal disposal. If the ashes are disposed of
by burial in soil or otherwise locally disperded, they should be retained in the closed container
until all cinders have thoroughly cooled.
Return the ash pan to its original position in the stove, and close.
Caution:
Never empty a stove in operation.
Never use your household or shop vacuum cleaner to remove ash from the stove; always
remove and dispose of the ash properly.
Creosote - formation and need for removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense in the relatively cool chimney ue of a slow-
burning re. As a result, creosote residue accumulates on the ue lining. When ignited this creosote
makes an extremely hot re. When burning wood, inspect the chimney connector periodically to de-
termine if a creosote buildup has occurred.
Chimney sweeping
Inspect the system regularly during the heating season as part of a regular maintenance sched-
ule. To inspect the chimney, let the stove cool completely.
Then, using a mirror, sight up through the ue collar into the chimney ue. If you cannot inspect
the ue system in this fashion, the stove must be disconnected to provide better viewing access.
Clean the chimney using a brush the same size and shape as the ue liner. Run the brush up
and down the liner, causing any deposits to fall to the bottom of the chimney where they
can be removed through the clean-out door.

Clean the chimney connector disconnecting the sections, taking them outside, and remov-
ing any deposits with a sti wire brush. Reinstall the connetor sections after cleaning, being
sure to secure the joints between individual sections with sheet metal screws.
If you cannot inspect or clean the chimney yourself, contact your local Morsø Dealer or a
professional chimney sweep.
If you do experience a chimney re, act promptly and:
1. Close the air control.
2. Get everyone out of the house.
3. Call the Fire Department.
Annual maintenance
Before the heating season, perform a thorough cleaning, inspection and repair:
Thoroughly clean the chimney and chimney connector.
Inspect the chimney for damage and deterioration. Replace weak sections of prefabricated
chimney. Have a mason make repairs to a masonry chimney.
Inspect the chimney connector and replace any damaged sections.
Check gasketing for wear or compression, and replace if necessary.
Check the glass for cracking; replace if needed.
Check door and handles for tightness. Adjust if needed.
3.4 Leaving the stove for extended periods
Important:
If the stove is to be left unused for any period of time, clean it out thoroughly and leave the spinner
slightly open to allow airow. Make sure that the ue does not allow rainwater to come anywhere
near the stove; install a chimney cap, but do not block o the ue completely.
These measures should ensure there is a slight movement of air through the stove, and that
the body of the stove remains dry, right into the corners.
Any ash left within an unred stove can attract moisture like blotting paper. If moisture is al-
lowed to settle within the stove, rust will form. Rust expands as it takes a grip. This can lead
to undue pressure on the stove joints, and this in turn may result in damage to the stove.
NOTE: It is best to thoroughly clean the stove after the heating season has concluded. Add-
ing a dessicant, such as kitter litter, into the ash pan helps absorb moisture during the sum-
mer months. Be sure to remove this prior to the heating season.
