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 appliance. (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 appliance 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 appliance. (See Fig.2)

pot, there is a "T" type fitting installed with inspection cap, in the
same was as the chimney pot opening.
It is prohibited to install a 90° bend for the initial segment, since
the ashes would quickly obstruct smoke passage, causing draught
