Additional accessories

Morsø also oers a comprehensive line of oor plates and accessory products that can fa­cilitate the safe and ecient 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.

1.0 Installing your Morsø stove

1.1 Unpacking the stove

1412: After removing the outer packaging, atten
it and lay onto the oor close to the stove; this can
then act as protective work surface during the as­sembly process.

Next, remove the legs from inside the stove. Careful­ly lift the stove from the wooden pallet 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. Following the removal of the wooden
packaging the heat shield must be tted to the un­derside of the stove at the same time as the legs uti­lising the same xing bolts. Please see drawing.

The stove should now be lifted and moved into the
upright position, avoiding excess load on the back
legs.

1442: Carefully lift the stove from the wooden pallet and set it carefully in place.

1452: The assembly of the soapstone stove 1450 is described separately and instructions
are enclosed with the soapstone packaging.

We recommend that two people perform the assembly and installation procedure. The Morsø
1412 weighs 70 kg, while the Morsø 1442 weighs 80 kg and the 1452 weighs 120 kg.

1.2 Installing the stove

The stove and chimney inst allations MUST comply to all current National and Loc al Building Regu­lations; your approved Morsø dealer or your local building control ocer can advise reg arding 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/clearance 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.

For all stoves, keep minimum a 500 mm distance to ceiling.

In situations where the stove is to be tted 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 classied as a non-combustible surface.

On the oor

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 under safety test
was 45°C. One should of course always make certain that the underlying oor sur face can bear the
weight of the stove.

Distance to furniture and soft furnishings

We recommend that the stove be installed 700 mm from furniture. Serious consideration
should also be given to positioning of any furniture that could be adversely aected by heat.
The clearances to combustible materials in front of the stove should be a minimum of 700
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 inrm. 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.

1.5 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. T he
wood-burning stove must never been connected to a chimney to which a gas-burning stove
or appliance is connected.

An ecient 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). Exceptions to this are: Smoke Exempt
Morsø stoves tted with a 125mm diameter ue collar. These can be connected to a chimney
system or liner with a minimal cross sectional area of 123 cm² (125mm 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 ues in connection with thatched roofs. See the section on Draft Conditions, 1.9.

The chimney or ue 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.

1.6 Fluepipe connections

Your stove is supplied ready for a top ue connection (3) the rear ue outlet is tted with a cover
plate and is situated behind the rear heat shield/convection panel. Where a rear ue 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 t he small ”bridges” in the circular cut­outs. Once the knock-outs have been removed
Unbolt the cast iron cover plate and install it into
the top of the stove. The ue collar can then be
bolted over the rear ue outlet using the clamps
provided.

Placement of smoke tray

In some cases Morsø stoves come ready­equipped from the factory with a smoke hood (1),
as shown in the diagram. (NOTE: Not all stoves
require a smoke hood). Where applicable, the
smoke hood must n ot be used if the stove is to be
installed with a rear ue outlet (3).

Please note: During ring, the cleaning valve
must always be installed correctly in the bae
as the top cover may otherwise overheat and
sustain permanent damage. Make sure that the
bae, smoke hood, rebricks and the riddling
grate are positioned correctly.

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 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 bre packing rope.

Only use stovepipe components that comply to National and Local Building Regulations.

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 ue manufacturers instructions concerning clearances
to combustible materials such as walls, oor joists and ceilings. The joint between the stove ue col­lar and the stovepipe must also be sealed using glass bre rope. It is important that the insulated ue
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 w ill inhibit exp ansion and could lead to dama ge of the stove top. Damage caus ed
to the stove in this way would not be covered by the manufacturers guarantee.

In the event that a chimney re resulting from faulty operation or prolonged use of damp wood
fuel, close the air vents completely and contact your local re department immediately.

Be aware of the following:

Cleaning procedure: Discuss this with chimney sweep or qualied installer prior
to or during the stove installation

Chimney draft: If the chimney draft is naturally poor it is better to install the ue from
the top of the stove so as to minimise any internal resistance of the ue gases.

Avoid having any more than 2 bends in the ue system and limit the length of the
oset between bends.

Fresh air supply

A wood-burning stove requires air for combustion. As a result, ring 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 re door is opened.
If it is necessary to install air grates, they must be positioned so that they cannot
be obstructed.
