1.7 Connecting to a brick chimney
Brick a flue bushing securely into the wall, and insert the flue pipe into it. The pipe must not
extend into the actual chimney opening, but only to the inside of the chimney aperture. The
joints between the stove/pipe and pipe/wall bushing must be sealed with the glass tape pro-
vided. It is not normally necessary to seal between any pipe joints.
If the flue pipe transitions from horizontal to vertical, it is a good idea to install it with a gentle
bend so as to avoid any loss of draught.
The flue pipe must be dimensioned in accordance with national and local regulations. Morsø
recommends, however, that flue pipes be made of 2 mm sheet steel, as this will extend the
service life.
1.8 Connecting to a steel chimney
If your installation involves routing the chimney straight up through the ceiling, it must comply
with national and local regulations concerning the distance of the chimney from flammable
ceiling material. The chimney must be sealed at the smoke outlet using the glass tape provid-
ed. It is important to install the chimney with a roof support, so that the stove does not bear
the weight of the chimney. (See the chimney manufacturer's instructions). Heavy weights on
the stove's top plate may cause it to crack. The Morsø warranty does not cover the top plate
if the chimney is installed without a roof support.
If a chimney fire should occur as a result of incorrect operation of the stove or prolonged use
of wet fuel, close the vents completely and contact the fire brigade.
Be aware of the following:
Discuss the cleaning options with your chimney sweep.
If there is insufficient draught in the chimney, it may be a good idea to install
the flue pipe straight up, so as to minimise smoke migration in the actual com-
bustion chamber.
Avoid having any 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 to 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 can-
not be obstructed.
