2.4 Fume exhaust
The fumes can be exhausted through a connection to a conventional flue or an external duct with double wall or
insulated pipe.
The fume exhaust connections must guarantee a minimum draft of 10 Pa so that the evacuation of fumes is ensured
in case of a temporary power failure.
- The installer must check the efficiency and state of the flue and its conformity with the
local, national and European regulations.
- Certified pipes and connections with adequate seals guaranteeing their tightness must be used.
- Clean the flue and respective connection at least once a year.

or air gap;
- it must preferably have a constant, free and independent round internal
section;
- it is advisable for the flue to have an inspectionable chamber for the
collection of solid materials
