This type of installation (See Fig.1) requires an insulated
chimney pot, even if the entire conduit is installed inside
the building. Besides, the structure must be inserted into a
properly ventilated skylight shaft.
In the lower part of the chimney pot there is an inspection
cover, properly isolated from wind and rain.
It is possible to use an existing chimney or a shaft via ducting.
For this type of installation the standards on ducted smoke
evacuation systems must be complied with. In the lower part
of the chimney pot, inside the home, there is a "T" type fitting
installed; externally there is another one installed, so that the
outside section can be inspected.
It is prohibited to install two 90° bend, since the ashes would
quickly obstruct smoke passage, causing draught problems in
the stove. (See Fig. 2)
