1.0 Installation of your Morsø stove
Installation of woodburning stoves must be safe and legal.
The installation must conform standard CAN/CSA-B365, Installation Code For
Solid-Fuel-Burning Appliances and Equipment Make-shift compromises during
installation can have consequences, the Installation of the 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 are
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.
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.
1.1 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 baffles 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.

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 code-approved masonry chimney with a
flue liner 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.

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
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 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.
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.

1.6 Mobile Home Installation
(Mobile home installation is only applicable for USA)
The Morsø 6100 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 A SLEEPING ROOM.
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 10 a cold air draft.
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 A GRATE, ANDIRONS, OR OTHER
WAYS OF ELEVATING THE FIRE – BUILD FIRE DIRECTLY ON HEARTH. 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
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 b urnt, 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.
To optimize efficiency: Burning wet wood has a negative impact on efficiency
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.
11
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. 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.
1. We recommend using the “top-down” method to light your wood-burning stove.
It is the most environmentallyfriendly method of lighting. Use two
firelighters and approx. 2-4 lbs of dry kindling sticks to quickly create a
glowing layer of wood. Place the firelighters directly under the top layer of
kindling sticks.This minimizes soot formation on the glass. Soot formation on
the glass is often caused by too vigorous burning in contact with cold
surfaces. If you avoid the formation of soot when lighting the fire and build
up a layer of hot embers, you will have minimal soot formation when getting
the fire burning again later.
2. The air supply must be fully open.
3. Light the fire.
4. After lighting, partially close the door, leaving it open an inch or two
to allow in plenty of combustion air.
12
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 two pieces of wood onto the embers. Leave half an inch or more between
each piece.
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.
10. For refueling, add a layer of wood while there are still plenty of live
embers, repeat steps 6-9. We recommend using fuel load with a weight of 3 lbs
(2 pieces) and up to 6 lbs (5 pieces). Always keep the fuel load beneath the
secondary stainless-steel air box. The space in front and above the air box is
reserved for volatile gas combustion only.
13
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 6lbs (5 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.
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.
Carbon monoxide detectors It is required in some jurisdictions to install
smoke and carbon monoxide detectors where heaters are installed. Install at
least one smoke detector on each floor of your home to ensure your safety. It
should be located away from the wood appliance and close to the sleeping
areas. Locating a smoke detector too close to a wood appliance can cause the
smoke detector alarm to sound if a puff of smoke is emitted while the wood
appliance door is open during reloading. Follow the smoke detector
manufacturers placement, installation, and maintenance instructions
14
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
Do not clean the glass while hot 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 benefit to the environment. Note: Should
be handed in to a recycling station as ceramic glass.
15
1. When you open the door, you will find two hinge pins, one in each hinge.
Remove the two hinge pins, 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!
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.
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
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.
16
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.
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.
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.
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.
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 slowburning 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.
17
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: 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 handle for tightness. Adjust if needed. How to clean
the inside parts of Morsø 6100 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.
ALWAYS USE ORIGINAL MORSØ SPAREPARTS
1. The bottom baffle is lifted up a bit and held in that position. Loosen the
side bricks.
2. Tip the side bricks and remove them from the fire chamber.
18
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. 5. The upper baffle is removed from the brackets and
lifted out of the firechamber.
19
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.

IMPORTANT!
How to heat safely for the environment and yourself!
· Use only dry wood
Use only dry (max. 20% moisture content) and untreated wood. The fuel must be
split and 8 – 12 cm thick.
· Light
Light with dry kindling (use 1 – 2 kg). Leave the door ajar and stay close to
the stove during the lighting phase.
· Good layer of embers
Be certain to have a good layer of embers before refilling. The wood should
light within 2 minutes. If the logs do not ignite it may, in an extreme case,
cause the flue gases to ignite which may pose a risk to material damage or
personal injury.
· Refuelling
When refuelling use 2 – 3 pieces of wood – no more than 2 – 2.5 kg.
· Ensure adequate air
I.e. clear and yellow flames.
· Never burn overnight
