ENG
1.1 Unpacking the stove
2110: After removing the outer packaging, unbolt the combustion chamber from the wooden
pallet and place it gently on its back. The cardboard packaging can be placed underneath to
prevent marring. Remove the leg pack from the stove and bolt each leg/panel securely to the
underside of the base on the combustion chamber, using the bolts provided (found inside the
stove).
We recommend that two people perform the assembly and installation procedure.
The Morsø 2110 weighs 125 kg.
The stove is intended for intermittent use.
1,2 Installing the stove
The stove and chimney installations MUST comply to all current National and Local Build-
ing Regulations; your approved Morsø dealer or your local building control officer can advise
regarding this. Ultimately, it is you and your installer who is responsible that the installation
complies.
1.3 Chimney sweep
It may also be wise to consult your local chimney sweep before installing the stove. After your
stove has been installed, it is advisable to have the chimney checked and swept at least once
a year. In any case, if your chimney has not been used for some time, it should be inspected
for cracking, bird nests, etc. before it is put back into use.
1.4 Stove placement/clerance requirements
Minimum Clearance requirements apply if the stove is placed near to combustible materials.
Permitted clearances to combustible materials are also indicated on the data plate on the rear
of the stove.

ENG In situations where the stove is to be fitted into a brick or non-combustible recess, we recom-
mend that the stove is installed with at least 10 cm clearance to the wall, this will allow room
air to circulate around the stove; also the maintenance of the outside stove is easier. When
applied to masonry, a layer of wallpaper is normally classified as a non-combustible surface.
On the floor
National and Local Building Regulations must again be observed when considering the type,
thickness and area of the hearth to be used in the installation. The hearth temperature under
safety test was less than 65°C.
One should of course always make certain that the underlying floor surface can bear the
weight of the stove.
Clearance to furniture and soft furnishings
We recommend that the stove be installed 800 mm from furniture. Serious consideration
should also be given to positioning of any furniture that could be adversely affected by heat.
The clearances to combustible materials in front of the stove should be a minimum of 800
mm. When lit, a wood-burning stove gets hot and therefore adequate protect must be pro-
vided, particularly in situations where there is a safety risk to children or the infirm. A suitable
safety guard around the stove should be considered.
The stoves handle also gets hot when the stove is lit, which is why a safety glove is included
with the stove.
In the event that a chimney fire occurs resulting from faulty operation or prolonged use of
damp wood fuel, close the air vents completely and contact your local fire department im-
mediately.
1.5 The chimney
Only if National or Local Regulations permit are you permitted to connect a stove into a chim-
ney that is shared by another appliance. YOU MUST be aware of any applicable Regulations
in this respect.
The wood-burning stove must never be connected to a chimney to which a gas-burning stove
or appliance is connected.
An efficient modern stove places heavy demands on the chimney, and you should have the
chimney regularly swept and inspected by your approved chimney sweep.
The cross-sectional area of the chimney (at its narrowest point) must comply with National
and Local Building Regulations. Generally, the area needed for a Morsø wood-burning stove
installation should measure at least 175 cm2 (150 mm diameter).
An over-sized chimney is generally hard to keep warm and results in poor draft. In cases
where there is an oversized masonry chimney, it is recommended that the chimney be lined
using an appropriate chimney lining system with the correct internal diameter.
With respect to the chimney termination, all chimneys should terminate in accordance with
National and Local Building Regulations.
Note that National and Local Regulations also apply with regard to the placement of chim-
neys and flues in connection with thatched roofs. See the section on Draft Conditions, 1.9.
The chimney or flue system must be equipped with access doors for inspection and cleaning.
The size of the cleaning door in the chimney must at least equal to that of the cross-sectional
area of the chimney.

ENG
1.6 Fluepipe connections
The stove comes standard with a flue collar (1) at the top and a cast-iron cover mounted on
the cast-iron back panel behind the convection back panels. If you want to install the stove
with a rear flue exit remove the knock out section of the convection back panel with steady
hammer taps to the small bridge which holds the knock out in place. Remove the flue collar
from the stove, unbolt the cast-iron cover from the back panel and install it in the top plate.
Centre the flue collar in the hole on the back side of the stove and bolt it securely in place
with the bolts and clamps provided.
Make sure that the baffle plate (2), the fire bricks and
the riddling are positioned correctly.

6
ENG 1.7 Connecting the stove to a masonry chimney
A wall sleeve should be bricked securely into the wall of the chimney at the appropriate height
and the stovepipe inserted centrally. The pipe must not extend into the actual chimney open-
ing, but rather must reach only to the inside of the chimney aperture. The gap between the
stovepipe and sleeve must be sealed using glass fibre packing rope.
Only use stovepipe components that comply to National and Local Building Regulati-
ons.
1.8 Connecting to a stainless steel insulated chimney system
If your installation involves taking the chimney straight up and through the ceiling, you must
comply with National, Local Building Regulations or flue manufacturers instructions concern-
ing clearances to combustible materials such as walls, floor joists and ceilings. The joint be-
tween the stove flue collar and the stovepipe must also be sealed using the glass fibre rope
provided. It is important that the insulated flue system is properly supported both at ceiling
level and at roof level. THE STOVE MUST NOT BEAR THE WEIGHT OF THE CHIMNEY SYS-
TEM (See chimney manufacturer’s instructions). Excessive weight on the stove will inhibit ex-
pansion and could lead to damage of the stove top. Damage caused to the stove in this way
would not be covered by the manufacturers guarantee.
In the event that a chimney fire occurs resulting from faulty operation or prolonged use of
damp wood fuel, close the air vents completely and contact your local fire department im-
mediately.
Be aware of the following:
Cleaning procedure: Discuss this with chimney sweep or qualified installer prior
to or during the stove installation
Chimney draft: If the chimney draft is naturally poor it is better to install the flue
from the top of the stove so as to minimise any internal resistance of the flue
gases.
Avoid having any more than 2 bends in the flue system and limit the length of
the offset between bends.
Fresh air supply
A wood-burning stove requires air for combustion and therefore you may need
to install additional ventilation to the room, especially so in well insulated
houses. If the air supply i inadequate the chimney draft may be too weak, with
the possible result that the stove will not burn properly; smoke spillage may
also occur during the refuelling process.
On a positive note, a properly installed wood-burner will give even the most ef-
ficient houses a pleasant and natural ventilation.

7
ENG
1.9 Draft conditions
If smoke spillage occurs when the fire door is opened, it is probably due to poor chimney
draft. This type of stove requires at least 12 pa of chimney draft to achieve satisfactory
combustion and smoke spillage prevention. However, in cases where the stove door is
opened too vigorously you could expect that slight smoke spillage may occur.
The flue gas temperature at the rated output is 302° C relative to 20°C.
If you have any doubts, you may want to have your installer measure the draft in the chimney.
Draft conditions
The chimney’s draft is the resulting effect within the flue caused by the diffe-
rence in temperature within the flue and the cooler temperature outside. Other
factors that can influence the level of draft include the length of the flue, insu-
lation of the chimney, adverse weather conditions or tall buildings or trees ne-
arby the flue terminal.
Poor draft occurs when:
• The atmospheric temperature difference is too low, e.g. a poorly insulated
chimney. If the chimney is excessively cool, it may help to ‘prime’ the flue be-
fore the fire is lit Just place a screwed-up sheet of newspaper in the flue-
ways of the stove and ignite.
• The outside temperature is too high, e.g. during the summer months.
• There is no air movement (wind) outside.
• The chimney is not tall enough, with the result that the terminal sits in the lee
of the roof surface or in the vicinity of tall trees or neighbouring buildings. The-
se conditions are also associated with downdraft where the flue gases are
pushed back down the chimney.
• Flue draft is diluted by residual air entering the chimney, e.g. due to inade-
quate fluepipe joints or leaks at the cleaning door or flue collar.
• Unsealed, unused fireplaces are connected to the chimney.
• The flue is blocked, e.g. by soot, due to inadequate cleaning, loose debris or
even a birds nest.
• The house is too tightly sealed (see section on Fresh air supply).
A good draft is achieved when:
• The temperature difference between the chimney and outside is high. This al-
so applies during firing, when the need is greatest.
• The weather is clear and there is a good wind.
• The chimney is of the proper height, i.e. minimum 4 meters over the stove and
the termination adequately clear of the roof line.

ENG
2.0 FIRING THE STOVE/USING YOUR STOVE
For wood firing, the shaking grate and the door valves should always be closed. Primary air is
only used for alternative fuel firing.
Pre-heated secondary air is added to the combustion process over the glass, and controlled
using the handle underneath the hot ash box.
The stove’s rated heat output is 8 kW. The efficiency is 72%. Your new Morsø stove is EN-
tested and recommended to be fired with wood.
N.B!
Wood is a material that contains a great deal of gas (approximately 75 %). The ga-
ses are released when the wood is lit and heated up. For this reason, it is important
that the gases are ignited quickly after stoking.
If the wood just lies smouldering, especially after re-stoking, a lot of smoke is
created, which, in the worst case, may cause an explosive ignition of the gasses,
resulting in damage to the stove.
In order to ignite the gases that are released from the wood, and to keep clear,
lasting flames during the combustion process, it is important to let in the required
quantity of oxygen (air supply) at all times.
The setting of the air supply, the method of ignition and the lighting intervals de-
pend on the draught in the chimney, the wind and weather, the amount of heat re-
quired, the fuel, etc. This means that it may take some time before you get to know
the correct functioning of the stove under any given circumstances.
Although you can fire your Morsø stove with almost all kinds of wood, you should
not fire with wet wood, or unseasoned wood. Wood ought to be stored under a roof
for at least 1 year, and preferably 2 years, with free access to wind. Wood should
be chopped as soon as possible after felling if it is to dry quickly. The wood can be
used once the moisture content is less than 20%. During the EN test, all stoves are
tested with wood with a moisture content of (16 ± 4)%.
Never use driftwood, as it usually has a high salt content, which damages both the
stove and the chimney. Impregnated and painted wood and chipboard emit poi-
sonous smoke and fumes, so they should not be used as fuel either.
Please note that liquid fuel may not be used in the stove.
Pieces of wood with a diameter greater than 10 cm should always be chopped.
The pieces of wood should be short enough to be able to lie flat over the layer of
embers, with air at both ends.
The maximum length of fuel in the stove is 40 cm.
The maximum quantity of fuel is 2.5 kg/hour (max. 3 pieces of wood each time you
re-stoke).
The first few times you light the stove, the fire should be moderate, so that the
heat-resistant paint can harden before firing more vigorously. During the hardening
phase, the paint may develop obnoxious smoke and smell the first time it is lit,
which is very normal. Make sure that the room is well ventilated during this period.

ENG
1. A layer of embers will form rapidly if the stove is
lit with 2 - 4 fire lighters or 7 - 10 rolled up sheets
of newspaper, underneath roughly 1 kg of dry
kindling.
2. Fully open the secondary air by sliding the
control handle to the left (controlled using the
handle underneath the ash lip)
3. After the paper/kindlings have caught fire, leave
the fire door ajar about 2-3 mm so that the
chimney draws well.
4. After 5-10 minutes the chimney draft should be
established, at this point close the fire doors. If all
the necessary conditions are met, a nice layer of
embers will start to accumulate after another 15
- 20 minutes.
2.1 Lighting and refuelling intervals
A lot of air is needed when first lighting the stove. When starting with a totally cold stove, it
may be helpful to leave the doors ajar (2-3 cm) during the first few minutes; the secondary air
intake should be fully open - handle underneath the ash lip. In cases of poor chimney draft,
the initial lighting process may be improved by adding more primary air (via the air control
inlets on the doors). Please note; excessive primary air may lead to temporary smoke dis-
colouration on the inner fire bricks and the glass panels. Therefore, it is recommended that
primary air only be added during the lighting process.
Wood fuel burns well when placed onto an ash bed on the grate of the stove. To achieve this
you should burn roughly 1-2 kg of dry kindling the first time you light the stove. You should
build and maintain the ash bed to a thickness of approximately 1 cm.

10
ENG 5. Refuelling of your stove should be done while there
are still glowing embers in the bed. Spread the em-
bers across the bottom, but concentrated mostly to-
wards the front of the stove.
6. Place three pieces of fuel weighing roughly 0.6 kg and
measuring about 25 cm in length across the embers in
one layer, with spacing of roughly 1 cm between the
pieces of wood.
7. When the secondary air supply (handle under the ash
lip) is opened all the way and the doors is closed, the
new fuel will ignite in a few minutes.
8. Once the new fuel has taken, adjust the secondary air
amount to the desired setting; optimal combustion will
continue until glowing charcoals are produced.
Under normal chimney draft conditions, expect to re-
fuel your stove every 60 - 70 minutes.
9. A new charge of wood can be added by repeating steps
5 & 6.

The stove door should normally be opened gently the first 2 - 3 centimetres, then you should
wait until the pressure has equalised before opening the door all the way. This technique will
prevent smoke from getting out, particularly when there is a poor draught.
The stove door should never be opened when the stove is being fired vigorously.
Once the wood has burned out, it becomes glowing charcoal. If a good layer of embers has
already formed on top of a sufficient layer of ash, the stove can keep warm for a very long
time, not least due to the favourable qualities of the cast iron.
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. Extreme conditions, such as
poor draught in the chimney, large quantities of wood or wet wood, may, in
the worst-case scenario, cause an explosive ignition.
When firing in the summer period, when there is minimal need for heat, the
combustion will be poor. The stove provides too much heat, so the combu-
stion should be reduced. But always remember to make sure that there are
lasting flames until the wood becomes charcoal. If you want a weaker fire,
stoke up using less wood.
If you fire the stove using wet wood, a lot of the fuel’s thermal energy will be
spent forcing the water out of the wood, without releasing any heat to the
stove. This incomplete combustion results in a layer of soot being left in the
stove, pipe and chimney.

ENG
3.1 External maintenance
The surface of the stove is painted with heat-resistant Senotherm paint. If the stove is used
too vigorously, the painted surface may take-on a greyish tinge. It is easily maintained by sim-
ply vacuuming the surface with a soft brush attachment and applying two light layers of paint.
Morsø stoves are painted in Morsø dark grey. The touch-up paint is available either as aerosol
spray or as regular brush-on.
3.2 Internal maintenance
Ceramic glass
If the stove is used and installed onto a flue with the correct draft, very little or no deposits
should appear on the ceramic glass. It is usual for soot deposits to appear during long slum-
bering fires however, once the fire has re-established a good operating temperature, these
deposits should burn off.
If the glass window becomes thoroughly covered in soot due to faulty operation or poor draft,
the soot can be easily removed using, e.g. Morsø Glass Cleaner, but please ensure that the
glass is cold before cleaning. Avoid fuelling the stove with wood that is so long that it presses
against the glass when the door is closed.
Internal cast-iron parts and/or wear components
The shaking grate, baffle plate and other internal components that are in direct contact with
the fire are all constituted as ‘wear’ components or consumables, as, they are exposed to the
most wear. When used properly, these parts will last for many years, but overly vigorous use
will naturally shorten the lifespan. The aforementioned parts are all easily replaceable.
If the baffle plate is damaged or warped and is not replaced in time, the top plate could be-
come subject to excessively high temperatures, which may lead to damage.
Note: that no unauthorised alterations to the stove design should be undertaken, and
always ensure that any replacement parts purchased are be Morsø original parts.
3.0 ROUTINE STOVE MAINTENANCE
Reasons for sooted glass window:
- fuel is too wet (green)
- pieces of fuel/uncut wood are too thick
- operating temperature of the stove is too low
- too much air coming through bottom grate
- POOR CHIMNEY DRAFT
Reasons for premature wear of internal parts
- Stove being used/fired too vigorously
- Too much air passing through the bottom grate
- Use of excessively dry wood (wood from old furniture)
- Excessive debris collection on baffle plate or inner fireback (see section on cleaning)
- Ash level too high in the ash pan (see section on ash

The rope gaskets in the door will need regular inspection in order to ensure and maintain full
control of your stove’s burning rate; over time the rope gaskets will harden and will become
less airtight; at this point you will need to remove and replace with new. Use only the genuine
Morsø gasket kit, which comes with detailed replacement instructions.
NOTE:
Normal wear components (inner parts) are not covered by Morsø’s 10-year guarantee.
Maintenance products (Spare Parts, Glass Cleaner, Paint, Gasket Kit, etc) are all available
from your authorised Morsø dealer.
3.3 Cleaning the stove
During normal use and sweeping of your stove and chimney, a layer of ash, soot or debris
can form, particularly on the top of the baffle plate or inner fireback. Any deposits allowed
to build-up over time will have an insulating effect on these parts, thus restricting expansion;
this will ultimately result in a shorter lifespan. The chrome-iron baffle plate and inner fireback/
bricks can easily be removed from the stove and should be regularly checked for debris and
cleaned. You must ensure that your chimney sweep removes all soot and debris from the
stove after the sweeping process.
Your chimney should be swept at least once a year; however a regular inspection of your
stovepipe and chimney will determine whether a more frequent approach should be adopted.
Ash
In order to achieve the highest combustion temperature possible when burning solely wood,
it is important that a 1cm deep bed of ash is established on top of the grate area. Excess ash
should be removed by simply agitating the grate by moving the riddling rod on the outside
of the stove; surplus ash will fall into the ash pan below the grate where it can be easily and
safely removed.
Be sure to empty the ash pan before it gets completely full; if the ash level reaches the under-
side of the grate, air flow through the grate will be restricted and will lead to over-heating and
premature wear of the grate parts.
When emptying the ash pan always dump the waste ash into a metal container (dustbin)
where it can fully cool before being taken away by your refuse collector. Ash from a wood-

4.0 Alternative fuel types
Your new Morsø stove is EN-approved for burning wood.
However, the stove is capable of burning other solid fuels as manufactured smokeless coal
or good quality anthracite (stove nuts). If you fire your stove with any fuel other than wood, it
may help to use coal insert/fuel economisers (available for most models), which simply fit into
the left and right sides of the firebox. Designed primarily to guide the solid fuel over the grate
area they also slightly reduce the firebox capacity allowing you to have smaller fires.
This is an additional accessory and can be purchased from your authorised Morsø dealer.
BITUMINOUS HOUSE COAL SHOULD NEVER BE USED IN YOUR STOVE.
Lighting with solid fuel
Install the coal insert (where available) into the left and right sides of the firebox.
All stove models are supplied with 1 front grate bar, however in the case of the 1400 series
an optional second front grate bar can be purchased from your Authorised Morsø Dealer. A
second front grate bar will allow for a deeper fire bed and a longer burn time.
IN ALL MODELS NEVER LOAD THE FUEL ABOVE THE FRONT GRATE BAR LEVEL.
All air vents must be fully open during the lighting process.
Start by placing 5-10 crumpled sheets of newspaper or 2 Morsø firelighters on the grate of
the stove; then carefully spread approximately 1 kg of well-dried kindling on the top. Light the
paper/firelighters. Once the kindling has fully ignited, gradually add a small quantity of solid
fuel, adding a little bit more once it has ignited. Continue in this manner until the entire grate
is covered with glowing coals. The level of fuel in the stove should never exceed the level of
the front grate(s). Once the bottom half of the fuel bed is glowing, you should partly close the
bottom vent (on the door). Once the stove has reached your desired temperature you can
maintain the output by opening further for more heat or closing for less heat. The top air regu-
lator must always be open just enough so that the flames burn almost clearly and the ceramic
glass window stays clean.
Note: In cases where smokeless fuels containing petrocoke are burned, a pale
greyish layer may be deposited on the inner glass surface when the stove is
lit. Fuels containing a high content petrocoke may cause a glistening in the
surface of the ceramic glass. Although visible, the structure of the glass will
remain intact and the stove safe. Glass is not covered by the manufacturer’s
10-year guarantee.

15
ENG
In order to maintain the combustion process, the entire grate area must remain covered by
glowing coals. If the coal layer is too shallow you will have less heat and it would not be nec-
essary to supply air via the top vent.
You must empty the ash pan whenever it becomes full. Different fuels have different ash con-
tent and therefore the regularity of the de-ashing process can vary.
Fuel storage
Your fuel supply should always be stored in a suitable, weather-tight coal bunker. These are
usually available through your approved coal merchant.
