INSTALLATION
2.10 Combustion gas exhaust
The ue pipe (1) and the connection to the stack (2) must conform
to applicable national and local laws and standards. Flue pipe
must be rigid, impermeable to fumes, able to withstand mechan-
ical strain, heat, and the action of combustion gases and the con-
densate formed by them.
The stack must be tted with a condensate trap and drain and the
ue gas exhaust pipe must be installed at a slope of at least 2° to-
wards the boiler. All condensate should be treated through a neu-
tralization media before being eliminated to the oor drain (3).

The boiler takes in combustion air from the boiler room. Room
vents must therefore be compliant with the relevant technical
standards.

Do not obstruct or restrict the air vents in the room where the
boiler is installed. Adequate ventilation is essential for correct
combustion and functioning.
