CHIMNEY

Chimney
The stove is type approved in accordance with EN 13240 and
obtained values are presented in the Performance declaration,
diameter of external connection is Ø150 mm .
The insert requires a draft in the chimney of at least –12
Pa. The draft is affected both by the length and area of the
chimney, and by how well sealed it is. Minimum recommended
chimney length is 3.5 m and a suitable cross-sectional area is
150-200 cm 2 (Ø140-160 mm). Note that a flue with sharp bends
and horizontal routing reduces the draught in the chimney.
The maximum horizontal flue is 1 m, on the condition that the
vertical flue length is at least 5 m.
Rearward connection
If a protective screen is selected, this must be installed before
making the chimney connection.
For the rearward connection it is recommended to use a 45°+45°
angle with soot hatch and with the centre 235 mm above the
connector.
Top connection
Create an opening in the top grate by using the shorter grate
profiles, see page 132. Cover the gap with a cuff.
Carefully check that the chimney is sealed and that there is no
leakage around soot hatches and flue connections.
Make sure that the connector gasket does not work loose when
the connection pipe is placed on the connector. If further
sealing material is required, heat-resistant sealant may be used.
It must be possible to sweep the full length of the flue and the
soot hatches must be easily accessible.
If two fireplaces are connected to the same chimney flue, the
stove must be equipped with self-closing door.
