Morso S50-40 Instructions For Installation And Use Manual page 24

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 ex-
tend 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 provided. 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 com-
ply with national and local regulations concerning the distance of the chimney from flamma-
ble ceiling material. The chimney must be sealed at the smoke outlet using the glass tape pro-
vided. 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 combustion
chamber.
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.
