Picture 13 . Connection to chimney
If possible, arches should be avoided. If not possible, then maximum number of arches should be 2.
It is desirable to insulate flue gas channel from the boiler to chimney, especially if there are arches and
longer sections. Flue gas probe is factory-installed in the housing of the exhaust gas fan. Prior to
commissioning of the boiler, check whether the probe is still located in its place after the transport, since
without adequately installed probe the boiler will not operate.
The chimney should be made of ceramic pipes, and around them there should be insulation of 3-5cm,
while the back outer layer should consist of bricks or special elements. If the chimney is not, however,
made of ceramic but of bricks, the light opening area of such chimney must be 30 % higher than the same
area of ceramic chimney.
The chimney must have a door for cleaning and the door must be well sealed. Chimney outlet on the roof
must be made in accordance with certain regulations. There are two different cases: if the roof angle is
smaller than 12° and if it is bigger than 12°. For the angle smaller than 12°, the height of the chimney
above the roof is 1m, while for the angle bigger than 12° please take a look at the
picture 14.
