6.3. Installation without chimney
The installation of the pellet stove when there is no chimney must take place, as in
Figure 9, by bringing the smoke exhaust pipe (with a minimum internal diameter of
80 mm for the air version and 100 mm for the water version) directly outside and
above the roof.
Properly anchored double-walled insulated stainless steel pipes should be used to
prevent condensation phenomena.
Provide at the base of the pipe a T for periodic inspections and annual maintenance,
as exemplified in Figure 9.
In Figure 10, the basic requirements for the installation of the compact chimney are
represented.
