UNI 20 onto Chimney
When installing the chimney we distinguish two situations:
Situation 1: Boiler is connected onto a standard chimney (masonry or metal) that has a
foundation and a full cross-section of the base plate to the top.
Situation 2: Boiler is connected onto prefabricated metal chimney attached to the facade.
Situation 1:
The chimney uses ceramic or metal pipes of circular cross-section of 130mm diameter.
Flue pipe must be insulated.
If the chimney, already exists and is of square cross-section, then the minimum
dimension of the intersection is 130x130mm.
It is not allowed to use a chimney for connecting multiple heating units.
It is not allowed to use the air vents like a chimney.
Top of the chimney to be protected with the chimney cap due for the impact of rain and
winds. Distance of chimney to cap is 200mm.
Chimney should come out above the roof according to the recommendations of the
showed in image. (Figure 9.4)
If some other objects are near the chimney, take this into account, and then increase the
height of chimney.
The chimney must have a connection to extract condensation and an inspection door.
The door should always be sealed well during the operation.
Situation 2:
In this situation flue pipe must go at least 1.5 meters vertically upwards in the very room
where the boiler is placed, and then penetrate through the wall and be connected onto the
chimney.
Flue pipe must have a T piece for condensation at the outlet from the boiler and the
possibility of dismantling for cleaning.
WARNING: Failure to follow the rules during the execution of flue and chimney can lead
to malfunction of the boiler and endangering to human health and even to endangering of
their lives. The biggest danger is from the toxic gases which are the products combustion
process. In these situations where no flue, chimney and combustion air have not been
constructed the way it was proposed in the instructions, Co. Radijator Engineering can not
take responsibility for unintended consequences.
