This type of installation (See Fig.4) requires an insulated
chimney pot, even if the entire smoke conduit is installed
outside the building.
In the lower part of the chimney there is a "T" type fitting
installed with inspection cap.
It is prohibited to install a 90° bend for the initial segment,
since the ashes would quickly obstruct smoke passage,
causing draught problems in the stove. (See Fig.2)
This type of installation (See Fig.5) requires an
insulated chimney pot, since the entire smoke
conduit is installed inside the building, and the part is
located inside a pre-existing chimney pot.
In the lower part of the stove there is a "T" type fitting
installed with inspection cap just like for the chimney
pot.
It is prohibited to install a 90° bend for the initial
segment, since the ashes would quickly obstruct
smoke passage, causing draught problems in the
stove. (See Fig.2)
