A chimney is properly functioning, if it meets the following conditions (Fig. 3):
-
If it extends the height of the rooftop (ridge, highest point) by at least 0.5 m,
-
If it extends the height of the house adjacent to the chimney, tree or other barrier,
-
If it is built inside house walls or, if the chimney is built on the outside walls, it must be well insulated,
-
If the chimney connection is tightly connected to the chimney, if the connection is extended,
-
If it is properly cleaned and free of birds nests, dirt and soot,
-
If the flue pipe does not enter deeply inside chimney opening, since this reduces the space for the
smoke to exit,
-
If all other required openings and cleaning access plates are well shut (sealed) to prevent generation of
“false” air,
-
If its duct is independent from other installation and has no cap on top.
