Connection to chimney

• The stove meets the requirements for connecting to chimneys
dimensioned for 350°C flue gas temperature.
• The external diameter of the connection sleeve is 150 mm.
• The stove 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. The minimum recommended chimney
length is 3.5 m and suitable cross sectional area is 150-200 cm²
(140-160 mm in diameter).

• 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.
• It must be possible to sweep the full length of the flue and the
soot doors must be easily accessible.
• Carefully check that the chimney is sealed and that there is no
leakage around soot doors and flue connections.
In the bag with these installation instructions
are two wing screws for the cover.
