Fresh Air Supply - Morso 2B Standard Instructions For Installation And Use Manual

1.7 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 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 SYS-
TEM (See chimney manufacturer's instructions). Excessive weight on the stove will inhibit ex-
pansion 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.
In the event that a chimney fire occurs resulting from faulty operation or prolonged use of
damp wood fuel, close the air vent completely and contact your local fire department imme-
diately.
Be aware of the following:
Cleaning procedure: Discuss this with chimney sweep or qualified installer pri-
or to or during the stove installation
Chimney draft: If the chimney draft is naturally poor it is better to install the
flue from the top of the stove so as to minimise any internal resistance of the
flue gases.
Avoid having any more than 2 bends in the flue system and limit the length of
the offset between bends.

Fresh air supply

A wood-burning stove requires air for combustion and therefore you may need
to install additional ventilation to the room, especially so in well insulated
houses. If the air supply in inadequate the chimney draft may be too weak, with
the possible result that the stove will not burn properly; smoke spillage may
also occur during the refuelling process.
On a positive note, a properly installed wood-burner will give even the most ef-
ficient houses a pleasant and natural ventilation.
