1.6 Connecting to a brick chimney
Securely fix a register plate (minimum 1.5 mm. thick rust protected sheet steel e.g. stainless)
into the chimney aperture with non-combustible materials. Insert the flue pipe no more than
20 mm. through the register plate, the pipe must not extend into the actual chimney opening.
The joints
between the stove collar and connecting flue pipe must be sealed with the 5 mm. diameter
gasket provided. The connection between the flue pipe and register plate mush have a similar
suitable flexile seal.
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 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 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.
