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 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)
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
appliance. (See Fig. 2)
