CHIMNEY

Chimney
The stove is type approved in accordance with EN 13240 and
must be connected to a chimney dimensioned for at least 350°C
the external connection diameter 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 suitable cross section area is 150-200 cm
(Ø140-160 mm in diameter). 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 rearward connection it is recommended to use a 45°+45°
angle with soot hatch and with the centre at least 285 mm
(without shelves/bench) respectively 335 (with shelves/bench)
above the connector.
Top connection
Create an opening in the top grate by using the shorter grate
profiles, see page 38. 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
2 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, see insert
instructions.
