We congratulate you on your choice of a Morsø stove. Morsø has been
producing some of the world’s best stoves since 1853. If you follow this
installation- and operating instruction carefully, we can assure you
many years of warmth and pleasure.
Optional Accessories
A wide range of accessories (such as handling gloves, fireside tools, glass cleaner and heatproof
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 8100 series meets the U.S. Environmental Protection Agency’s emission limits for
wood heaters sold on or after July 1, 1990
The Morsø 8100 series 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 specific test conditions this heater has been shown to deliver heat at rates ranging from
10,900 to 25,400 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.

Installation requirements vary in different districts, and the local building officials have the final
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
dangerous situations like chimney - and house fires. Follow the instructions
carefully and do not deviate from them as it may cause injuries to people or
property.
1.0 Installation of your Morsø stove
Installation of woodburning stoves must be safe and legal.
If your Morsø stove is not installed correctly, it may cause a house fire. To reduce
the risk of fire, the installation instructions must be followed carefully. Contact the
local building officials 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 floor protection must be adequate and must be made correctly according to ´the
requirements.
All neccessary approvals are needed from the local building officials.
The data plate, which is located on the back of the stove, provides information regarding safety
testing information, name of certified testing laboratory, and installation requirements.
1.1 Checking loose parts in the stove
After unpacking, check that the fire bricks are firmly in position and have not shifted in transit.
Check also that the air control works freely.
Before starting the initial fire, make sure that the baffle is placed correctly.
Standard Accessories
A Morsø glove and ceramic flue connection gasket are standard accessories that usually can be
found in the ashpan or firebox area.
5
1.2 The chimney / flue system
Note that the flue system must be independently secured and must not rely on the stove for
support.
The stove must not be connected to a chimney flue serving any other appliance.
(Several flues may run up a single chimney stack; use one flueway 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.) or a code-approved
masonry chimney with flue liner 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 inches
diameter (or equivalent cross section), and should not be significantly larger than this. Too
large a section will tend to allow the flue 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 flue collar to the top of the chimney.
Local conditions like for example - roof constructions, large trees nearby and high altitude, may
influence the chimney draft and height. Therefore, contact the local professional chimney sweep
or your Morsø dealer.
Typical Factory-Built or Masonry Chimney Installations

1.4 Connection to the existing chimney
A chimney connector is the double-wall or single-wall pipe that connects the stove to the chimney. The chimney itself is the masonry or prefabricated structure that encloses the flue. Chimney 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 appliances.
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 fumes 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 flue 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 instructions
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.
1.3 Flue Connection
The stove is supplied from the factory with a round blanking plate blocking off the top and rear
flue exit (behind the rear shield plate). A flue collar are placed in the firebox area.
Use a 24 MSG black or blue chimney connector or listed double wall chimney connector. Refer
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.
The collar can be fitted to the rear outlet. Simply knock out the round panel on the rear heat
shield plate to reveal the cast iron plate. Untwist the blanking plate and the flue collar and swap
their positions. Re-secure by pushing down and tighten the enclosed screws.
Position the stove and connect to the flue system.
Wear gloves and protective eyewear when drilling, cutting or joining sections of chimney
connector
Where passage through a wall or partition of combustible construction is desired, the installation shall conform to CAN/CSA-B365.

1.5 Positioning the stove
Distance to walls and lintel
When the stove is positioned near combustible materials, observe all current local and national
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 (fireplace installations require greater clearances above
the stove - see below in the clearance chart). 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 effects 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.
If using rear exit, the floor protection must extend beneath the chimney connector and 2-in
beyond each side.

Distance to furniture
The recommended minimum distance from stove to furniture is 30 inches. Note that some
furniture is more easily affected 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 drying clothes,
newspapers, firewood etc.
1.6 Mobile Home Installation
The Morsø 8100 can be installed in a mobile home if equipped with an outside combustion 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 flooring.
• 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 mobile home installation.
• Floor protection requirements in section 1.5 must be followed precisely.
• In Canada, this appliance must be connected to a 6” (152 mm) factory-built chimney
conforming to CAN/ULC-629M, STANDARD FOR FACTORY BUILT CHIMNEYS. Floor
protection as referenced in section 1.5 must be followed, as well as use of Canadian
Floor Protector.
• Follow the chimney and chimney connector manufacturer’s instructions when installing the flue 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 floor 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
ENCLOSED SPACE SUCH AS AN ATTIC OR GARAGE.
DO NOT INSTALL IN SLEEPING ROOM.
Rotatable smoke outlet
The rotatable smoke outlet is locked during transportation. The screw that locks the smoke
outlet is located next to the little yellow label on the edge of the cast smoke outlet, and can be
loosened with a 2 mm Allen key.
N.B.: The smoke outlet must not be lifted when the screw that locks the rotatable smoke outlet
has been loosened. If you lift the smoke outlet, the steel balls on which it turns may fall out.
11
2.0 Operation
2.1 Before you start firing
For Use with Solid Wood Fuel Only. Do Not Overfire, If Heater or Chimney Connector
Glows You Are Overfiring. Inspect and Clean Chimney Frequently. Under Certain
Conditions of use creosote buildup may occur rapidly. Because of risk of smoke and flame
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 fluids to start the fire.
Do not burn garbage or flammable fluids.
Do not use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter or fluid or similar
liquids to start or freshen up a fire in this heater. Keep all such liquids away from the heater
while it is in use.
CAUTION:
THE STRUCTURAL INTEGRITY OF THE MOBILE 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 - BUILD 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 sufficient 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.
12
The secondary air is injected into the flue gases above the fire resulting in a cleaner, more efficient
combustion process. The supply of secondary air and Pilot air is fixed open and is not adjustable.
For extra safety, your stove should be with a removable handle.
2.2 Lighting and loading intervals
When first 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 first 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 floor of the stove, you should use 2-4 pounds of dry kindling
at the initial lighting. If possible, maintain a 1-1.5 inch (2-3 cm) layer of ash on the floor of the
combustion chamber for added insulation.
Caution: Do not place fuel within the installation clearances for the stove or within the space
required for loading fuel and ash removal.
Starting the First Fire
The initial fire 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 off by the paint. Ventilate the room
during this phase.
The setting of the air control, lighting techniques and loading intervals will depend on chimney
draft, the fuel used, the heat required and so on. Some basic techniques are outlined below.
In principle
Your stove should be with Primary and Secondary air and Pilot air inlets.
Primary Air is controlled using the lever situated over the door. Moving the control lever to right
position will open the air inlet and will allow a supply of preheated air to enter the firebox via the
‘airwash’ system situated inside the stove and above the glass.
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 season
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-puffing 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.
13
Step-by-step procedure
1. The air supply must be fully open.
3. Light the fire. An ember bed will quickly be
formed by lighting with firestarters, Morsø
kindling bags or 7-10 pieces of twisted
paper under the dry kindling wood.
4. After lighting, partially close the door,
leaving it open an inch or two to allow in
plenty of combustion air.
2. For lighting the fire use 2-4 pounds of dry
kindling wood.
14
5. When the chimney is warm after about
5-10 minutes, the door should be closed.
A suitable layer of ember will be formed
after about 15-20 minutes.
6. When ready to reload, use a poker to
spread the embers across the firebox floor,
bringing plenty towards the front of the
stove.
7. Lay three pieces of wood onto the embers.
Leave half an inch or more between each
piece.
Max. fuelload 1,2 pounds/h.
8. Close the door. Leave the primary air
supply fully open.
If it does not light, leave the door slightly
ajar to allow the necessary amount of air
in to ignite the wood.
Close the door again once the wood has
kindled.
9. After a few minutes, adjust the primary air
supply to suit your heating requirements.
Make sure that there is always enough air
to sustain clear, enduring flames when you
reduce the amount of combustion air, and
afterwards.
15
Do not for any reason attempt to increase the firing of your heater by altering the air
control adjustment range outlined in these directions.
Warning: Fireplace stoves must never be left unattended with the door open.
If the door is left partly open, gas and flame may be drawn out of the fireplace stove
opening, creating risks from both fire and smoke. We recommend that you fit a smoke detector
in the room where the stove is installed.
DO NOT OVERFIRE THIS HEATER. Overfiring may cause a house fire, or can result in
permanent damage to the stove. If any part of the stove glows, you are overfiring.
The maximum recommended weight of wood fuel per load is 2.5 kg/h/5.5Ibs (approx 3 split logs).
Under normal firing, the average flue temperature in the stove pipe, measured 20 cm above the
stove, is approx. 300° C (550°F). The maximum flue temperature in the stove pipe must not exceed
450° C (750°F). If the flue temperature exceeds 450°C (750°F), it is considered as over firing 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 fire simply
will not respond, a poor draft is almost certainly to blame. (In a very few cases, there may be
insufficient fresh air getting into the room - see installation advice above). Take advice from your
stove supplier on how best to upgrade your flue system to improve draft.
10. For refueling, add a layer of wood while
there are still plenty of live embers, repeat
steps 6-9.
16
3.0 MAINTENANCE
When perfoming maintenance on your stove, always protect yourself, using safety goggles
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 first firing after touching up, the stove will
give off 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 off as temperatures increase.For heavier
deposits that will not burn off, 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.
Rules of woodburning
If you want less heat, put fewer logs on the stove and reduce the amount of air. It is still important
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.
We would strongly recommend that you do not leave your stove alit at night. It harms the environment, and constitutes very poor use of the wood, as the gases in the wood do not ignite at
the low temperature, but settle as soot (unburned gases) in the chimney and stove instead.
17
To reduce the risk of breaking the glass, avoid striking the glass or slamming the
door.
Internal service parts
The flame-path equipment - consisting of the ashpan, grate, firebricks, Cast iron fire plates,
glass, baffle and flue collar - are subject to the extremes of heat produced by the fire. From
time to time, one or other of these parts may need replacing as a matter of routine maintenance.
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 benefit to the environment.
Note: Should be han- ded in to a recycling station as ceramic glass.
1. When you open the door, you will find two small M4 unbraco screws, one in each hinge. Unscrew
the two screws, lift the door off the hinges and place it face down on a sheet of cardboard or
other nonabrasive fabric.
2. Unscrew the 4 bolts that secure the glass. (In the event that a bolt sheers off when being
unscrewed, remove the remaining body of the bolt by drilling down its centre 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, making
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 fitting 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 excessive pressure
on the glass, resulting in cracking - important!
18
Dispose the ash in a metal container with a tight fitting lid.
The closed container of ashes should be placed on a noncombustible floor or on the ground,
well away from all combustible materials, pending final 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 the door.
Clean the flue/chimney - all the way from the stove to the flue terminal point above the house.
A good routine is to clean the flue after each heating season in any case, and inspect prior to the
season to ensure that bird’s nests or other blockages have not occurred during the off season.
Ash disposal
Empty the ashpan on a daily basis or as needed. Ash allowed to build up towards the underside
of the grate will trap heat and could cause premature failure of the grate.
Empty the ashpan according to this procedure:
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. Take out the ash pan, making sure to keep it level to avoid spilling ash.
3.3 Cleaning the Stove and the Flue
Check for soot above the baffle plate and around the flue outlet every month or so to start with.
If the stove suddenly becomes sluggish, check for a soot fall around the flue collar or in the flue/
chimney.
Gasket
The gasket around the perimeter of the door may harden over a period of time. It should be
replaced if it becomes difficult to close the doors or if air starts to leak in around the perimeter
of the doors, causing the fire to become a little less controllable. A morsø rope gasket kit is
available from your stove supplier.
The chimney and chimney connector should be inspected at least once every two months
during the heating season to determine if a creosote buildup has occurred. If creosote has
accumulated, it should be removed to reduce the risk of a chimney fire.
NOTE: The flame-path equipment, the ceramic rope and the paint finish 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.
Should the baffle be distorted by an overfire, the stove will still function, although its efficiency
may be compromised. Replace it as soon as possible.
Reasons for fast internal wear and tear
Persistent heavy firing
Soot and ashes left to accumulate
19
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 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. When burning wood, the chimney and chimney connector
should be inspected at least once every two months during the heating season to determine if
a creosote buildup has occurred. If creosote has accumulated, it should be removed to reduce
the risk of a chimney fire.
Chimney sweeping
Inspect the system regularly during the heating season as part of a regular maintenance schedule.
To inspect the chimney, let the stove cool completely. Then, using a mirror, sight up through the
flue collar into the chimney flue. If you cannot inspect the flue 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 flue 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 removing any
deposits with a stiff wire brush. Reinstall the connector 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 fire, act promptly and:
Close the air control.
Get everyone out of the house.
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 handle for tightness. Adjust if needed.
How to clean the inside parts of Morsø 8100
When cleaning the inside parts of the stove in connection with the annual visits from your local
chimney sweep we recommend that you remove the inside parts from the fire chamber. Please
be careful as the vermiculite parts are porous. Cleaning of the stove must be done when the
stove is cold.

2. Tip the side bricks and remove them from
the fire chamber.
3. Tip the other side brick and remove it from
the fire chamber.
4 When the side bricks are removed the
bottom baffle is lowered and lifted out of
the fire chamber.
1. The bottom baffle is lifted up a bit and held
in that position. Loosen the side bricks.

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 air
control slightly open to allow airflow. Make sure that the flue does not allow rainwater to come
anywhere near the stove; install a chimney cap, but do not block off the flue 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 unfired stove can attract moisture like blotting paper. If moisture is allowed
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. Adding
a dessicant, such as kitter litter, into the ash pan helps absorb moisture during the summer
months. Be sure to remove this prior to the heating season.
We hope you have many years of carefree warmth in its company. Some initial experimentation
with loading and running techniques will decide your normal routine. If you have any problems
after this short learning phase, please refer to your stove dealer. Should they be unable to help
for any reason, please contact us in writing at the address on the front of this publication.
5. The upper baffle is removed from the
brackets and lifted out of the firechamber.
