The chimney must have a small door for cleaning which must seal well. Chimney exit on the roof
must be made in accordance with the applicable regulations. There are two different cases: if the angle
of the roof is less than 12 degrees and if the angle of the roof is greater than 12 degrees. For the angle
less than 12 degrees, the height above roof is 1 m and for the angle which is greater than 12 degrees,
the drawing below should be consulted.
If you are of opinion that the chimney is too strong and that too much cold air passes through the
boiler, at the exit of the boiler there is a flap which can be used to reduce the flow of the exhaust gases.
The chimney should be regularly cleaned or at least once a year.
If the chimney is not made with the proper height, cross-section or if it is not
cleaned, complications in boiler operation are possible. First of all, high temperature
operation is not possible, i.e. there is no maximum operating power, and the
consequence is the occurrence of condensation which affects the working life of the
boiler.
Weak chimney is the main reason why during the ignition of the boiler the
smoke appears on upper or lower door, especially when the number of revolution of
the fan is higher.
