Instructions for installation and use

Enjoy your new Morsø stove!
Morsø, the biggest stove company in the Danish market, has been making wood-burning stoves of the highest quality since 1853. Just follow the instructions below, and we are certain that you will be able to use and enjoy your new stove for many years.

Additional accessories
Morsø also offers a comprehensive line of floor plates and accessory products that can facilitate the safe and efficient operation and maintenance of your Morsø stove.

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.

The Clean Air Act 1993 and Smoke Control Areas

Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any fixed boiler if located in a designated smoke control area. It is also an offence to acquire an “unauthorised fuel” for use within a smoke control area unless it is used in an “exempt” appliance (“exempted” from the controls which generally apply in the smoke control area).
In England appliances are exempted by publication on a list by the Secretary of State in accordance with changes made to sections 20 and 21 of the Clean Air Act 1993 by section 15 of the Deregulation Act 2015. Similarly in Scotland appliances are exempted by publication on a list by Scottish Ministers under section 50 of the Regulatory Reform (Scotland) Act 2014.
In Wales and Northern Ireland these are authorised by regulations made by Welsh Ministers and by the Department of the Environment respectively.
Further information on the requirements of the Clean Air Act can be found here at:
https://www.gov.uk/smoke-control-area-rules
Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision of smoke control areas and you can contact them for details of Clean Air Act requirements.

The Morso Squirrel 1010 has been recommended as suitable for use in smoke control areas when burning wood logs. The Morso Squirrel 1010 must be fitted with a permanent stop to prevent closure of the secondary valve beyond 30% open.

Installing your Morsø stove

  1. Unpacking the stove
    After removing the outer packaging, flatten it and lay onto the floor close to the stove; this can then act as protective work surface during the assembly process.

Next, remove the legs from inside the stove. Carefully lift the stove and gently lay the stove onto its back and unscrew the heat shield from the underside of the stove. Now screw the legs and the Heat shield into position on the underside of the base. The heat shield must be fitted to the underside of the stove at the same time as the legs using the same fixing bolts. Please see drawing.
The stove should now be lifted and moved into the upright position, avoiding excess load on the back legs.
We recommend that two people perform the assembly and installation procedure.
Morsø 1010 weighs 67 kg (short leg version) and 69 kg (long leg version)

  1. Installing the stove
    The stove and chimney installations MUST comply to all current National and Local Building 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.
    Carbon monoxide detector
    A CO Monitor must be fitted into the same room as the appliance upon installation and that the alarm is compliant with British Standards BS 50291. Where battery powered alarms are selected, alarms with ‘sealed for life’ batteries rather than alarms with replaceable batteries are the better option.

  2. 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.

  3. Stove placement/clearance requirements
    Minimum Clearance requirements apply if the stove is placed near to combustible materials.
    If the walls are made of flammable material, there will be distance requirements concerning both the flue pipe and the stove.
    Most often it will be the smoke pipe that will have the longest distance requirement and the total installation must comply with the longest distance.
    Distance requirements for the stove

Minimum clearances to combustible surfaces:

Stove type| Behind the stove (A)| To the sides of the stove (B)| Corner
Morsø 1010| 175 mm| 500 mm| 300 mm


Distance requirements for flue pipe

If using un-insulated flue pipe in a combustible environment then the distance between combustibles and the flue pipe must be 3 times the diameter of the pipe but never less than 375 mm.
For other CE approved smoke pipes (insulated) the distance requirement will be indicated on the pipe.
Distance requirements for the complete installation (stove and flue pipe)
Longest distances, regardless of whether it is from the flue pipe or from the stove must be observed.
In situations where the stove is to be fitted into a brick or non-combustible recess, we recommend that the stove is installed with at least 10 – 15 cm clearance to the wall, this will allow heat 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. Max Hearth temperature during the safety test was 94°C for the 1010 model on short legs. One should of course always make certain that the underlying floor surface can bear the weight of the stove.
Distance to furniture and soft furnishings
We recommend that the stove be installed 1000 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 850 mm. When lit, a wood-burning stove gets hot and therefore adequate protect must be provided, 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.

  1. The chimney
    Only if National or Local Regulations permit are you permitted to connect a stove into a chimney that is shared by another appliance. YOU MUST be aware of any applicable Regulations in this respect.
    The wood-burning stove must never been 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 chimneys 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 crosssectional area of the chimney.

  2. Fluepipe connections
    Your stove is supplied prepared for a top flue connection (3) and the rear flue outlet is fitted with a cover plate and is situated behind the rear heat shield/convection panel.
    Mounting the flue collar pointing upwards
    Before installing the flue collar to the top, remove the baffle (2) and smoke hood (1), which is located under the top cover by turning it clockwise. Then insert and tighten the flue collar (3) with the l oose screws and clamps. Replace the smoke hood (1) by lifting it into place and turning it counterclockwise and place the baffle again.

Mounting the flue collar to the rear
Where a rear flue installation is required, simply knock out the steel plates in the rear heat shield/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 cover plate and install it into the top of the stove. The flue collar can then be bolted over the rear flue outlet using the loose bolts and clamps.
Where applicable, the smoke hood (1) must not be used if the stove is to be installed with a rear flue outlet (3).
Make sure that the baffle (2), smoke hood, firebricks and the riddling grate are positioned correctly.

  1. 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 opening, 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 Regulations.

  2. 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 concerning clearances
    to combustible materials such as walls, floor joists and ceilings. The joint between the stove flue collar and the stovepipe must also be sealed using glass fibre rope. 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 SYSTEM (See chimney manufacturer’s instructions). Excessive weight on the stove will inhibit expansion 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 resulting from faulty operation or prolonged use of damp wood fuel, close the air vents completely and contact your local fire department immediately.
    Be aware of the following:
    Discuss the cleaning options with your chimney sweep.
    Avoid having more bends than necessary, and limit the length of the flue pipe so as not to reduce the draught.
    Fresh air supply
    A wood-burning stove requires air for combustion. As a result, firing a wood- burning stove will help create a healthy climate in your house. If the house is very tightly sealed, and particularly if there is a cooker hood or ventilation system in the house, it may be necessary to install an air grate in the room in which the wood-burning stove is installed. Otherwise there may not be enough draught in the chimney, which may result in the stove not being able to burn properly, and smoke may come out of the stove when the fire door is opened.
    If it is necessary to install air grates, they must be positioned so that they cannot be obstructed.

  3. 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 smoke gas temperature at the rated output is 256˚ C relative to 20˚ C.
    If you have any doubts, you may want to have your installer measure the draft in the chimney.
    Draught
    The draught in the chimney is the result of the difference between the high temperature in the chimney and the cooler temperature outside. Other factors that determine whether sufficient negative pressure can be produced to create a draught include the length and insulation of the chimney, and wind and weather conditions.
    The draught will be reduced when:

    • The temperature difference is too low, e.g. in connection with a poorly insulated chimney.
      If the chimney is cold, it may help to light (burn up) a rolled-up newspaper in the chimney’s cleaning door.

    • The outside temperature is too high, e.g. during the summer.

    • There is no wind.

    • The chimney is not tall enough, with the result that it sits in the lee of the roof surface or tall trees.
      These conditions are also associated with the greatest risk of smoke coming back down the chimney.

    • Air is entering the chimney in undesired places, e.g. through cracked joints or leaks in the cleaning door or the flue pipe.

    • Unsealed, unused fireplaces are connected to the chimney.

    • The flue pipe and chimney are clogged up with soot due to inadequate cleaning.

    • The house is too tightly sealed (please see the section on Fresh air supply).
      A good draught is achieved when:

    • There is a big difference between the temperature in the chimney and outside, i.e. when the need for heating is greatest.

    • The weather is clear and there is a good wind.

    • The chimney is of the proper height, i.e. Minimum 4 metres above the stove, and clear of the spine of the roof.

Firing the stove/Using your stove

The heat output of your stove is regulated by means of the air inlets. The primary air supply, i.e.
the air which passes through the shaking grate, is controlled by the bottom draft vent, while the secondary air supply, i.e. the air supplied to the fire across the glass window, is controlled by the top draft vent.
The stove’s rated heat output is 4.9 kW. The efficiency is 79 %.
Your new Morsø stove is EN-tested and recommended to be fired with wood.
The stove is intended for intermittent use.

NB!
Wood is a material that contains a great deal of gas (approx. 75%). The gases are released when the wood is lit and heated. For this reason, it is important that these 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 gases, 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 depend on the draught in the chimney, the wind and weather, the amount of heat required, 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 is less than 20%. During the 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 poisonous 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 exceeding 10 cm should always be chopped. The pieces of wood should be short enough to be able to lie flat over the layers of embers, with air at both ends. The maximum length of fuel in the stove is 30 cm. The maximum quantity of fuel is approx. 2 kg/hour (max. 2 pieces of wood each time you re-stoke).

The first few times you light the stove, the fire should be moderate so that the heatresistant 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.

When heating up or cooling down, the material is exposed to major temperature differences that may cause the stove to give off creaking sounds.

  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 door ajar (2-3 cm) during the first few minutes; the secondary air intake, – the upper valve should be fully open. You should build and maintain the ash bed to a thickness of approximately 1 cm.
    The lower valve is only used during the start-up phase and only if you experience bad draft conditions.

  2. We recommend using the “top-down” method to light your wood-burning stove. It is the most environmentally-friendly method of lighting. Use two firelighters and approx. 1.5 kg of dry kindling sticks to quickly create a glowing layer of wood. Place the firelighters directly under the top layer of kindling sticks.

  3. Fully open the top vent so that the secondary air supply can enter the firebox.

  4. After the paper/fire lighters have caught fire, leave the fire door ajar about 2-3 cm, so that the chimney draws well.

  5. After 5-10 minutes the chimney draft should be established, at this point close the fire door. If all the necessary conditions are met, a nice layer of embers will start to accumulate after another 15 – 20 minutes

  6. Refuelling of your stove should be done while there are still glowing embers in the bed.

Spread the embers across the bottom, but concentrated mostly towards the front of the stove.

6. Place two pieces of fuel weighing roughly 0.5-0,7 kg and measuring about 25 cm in length across the coals in one layer, with spacing of roughly 1 cm between the pieces of wood.  

7. When the secondary air supply (top vent) is opened all the way and the door is closed, the new fuel will ignite in a few minutes.  

Important!
It is important that the fresh quantity of wood starts to burn quickly. To ensure the fuel lights quickly, open the combustion air to max. or leave the door ajar to allow in the amount of air needed to light the wood.
If, however, the wood only smoulders, there will be a strong build-up of smoke, which at worst can cause an explosive ignition of the flue gases with the risk of material damage and personal injury.

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 refuel your stove every 45-55 minutes.
Make sure that there is always enough air (oxygen) to maintain clear, lasting flames when, and after, reducing the amount of combustion air.

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.

Operation with door or dampers left open
Operation with the air controls, appliance dampers or door open can cause excess smoke.
The appliance must not be operated with air controls, appliance dampers or door left open except as directed in the instructions.
Once the wood has burned out, it becomes glowing charcoall. 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.

Fuel Overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause excess smoke.

Refueling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive smoke emission can occur. Refueling must be carried out onto a sufficient quantity of glowing ember and ash that the new fuel charge will ignite in a reasonable period. If there are too few embers in the fire bed, add suitable kindling to prevent excessive smoke.

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 combustion 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.

Routine stove maintenance

  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 simply 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.

  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 slumbering fires however, once the fire has been re-established to a burn brightly, these deposits will 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.
    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.
      Internal cast-iron parts and/or wear components
      The 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 replaced.
      If the baffle plate is damaged or warped and is not replaced in time, the top plate could become subject to excessively high temperatures, which may lead to damage here also.
      Note that no unauthorised alterations to the stove design should be undertaken, and always ensure that any replacement parts purchased must be Morsø original parts.
      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 furnitures)

    • 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)
      Vermiculite firebricks
      It should be expected that at sometime the Vermiculite firebricks will show some signs of cracking in its surface; however this is regarding as natural and will not alter the overall function.
      Gaskets
      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 extended guarantee
      Maintenance products (Spare Parts, Glass Cleaner, Paint, Gasket Kit, etc) are all available from your authorised Morsø dealer.

  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 buildup over time will have an insulating effect on these parts, thus restricting expansion; this ultimately result in a shorter lifespan. The chrome-iron access door 1464 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
    As noted above, there should be circa 1 cm insulating layer of ash on top of the grate when burning wood only in order to achieve a high combustion temperature. Excess ash can be removed by pushing the ash into the ash pan below.
    Be sure to empty the ash pan before it gets completely full; if the ash level reaches the underside 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 woodburning stove does not benefit your garden as fertiliser.
    We highly recommend lubrication of hinges and closing mechanisms once per year or as needed, not only to ensure smooth functioning and longevity, but also to mitigate wear and tear.
    We recommend copper grease as a lubricant or another equally heat-resistant grease.

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 pieces of wood
    • no more than 2 kg.
  • Ensure adequate air
    I.e. clear and yellow flames.

  • Never burn overnight
