3.4 Chimney connection
The optimal placing of the boiler on the uptake is such that the strait line which connects the centre of
exit of flue gases from the boiler and the centre of connection to the chimney is gently raising (up to
3%) (
Figure 7
).
Figure 7. Connecting of the boiler to the chimney
Arches should be avoided if possible; if not, the maximum number of arches should be 2. It is
preferable to insulate the smoke channel from the boiler to the chimney, especially if there are arches
and longer parts.
The chimney itself should be made of ceramics pipes, around the pipes
3 – 5 cm thick insulation shall be placed and the last outside layer shall be made of brick or special
chimney elements.
If the chimney is not made of ceramics but of bricks, the area of unobstructed section of such chimney
shall be 30% greater than the area of the chimney made of ceramics. The minimum height of the
chimney is 7m.
