Combustion Gas Exhaust - Riello RTC-80 Series Installation, Operation And Service Manual

INSTALLATION

2.12 Combustion gas exhaust

The flue 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 fitted with a condensate trap and drain and the
flue gas exhaust pipe must be installed at a slope of at least 3° to-
wards the boiler. All condensate should be treated through a neu-
tralization media before being eliminated to the floor drain (3).
(*) See "Draining the condensate".

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.
