Connecting To A Brick Chimney; Connecting To A Steel Chimney; Fresh Air Supply - Morso S80-90 Instructions For Installation And Use Manual

1.6 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.

1.7 Connecting to a steel chimney

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 SYSTEM (See chimney man-
ufacturer'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.
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-burn-
ing 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.
