2.6 Flue connection

Important
The unit is a B23-type with combustion air drawn from the place of installation, and fume exhaust by means of a fan
(operation with flue pressurised), and must be connected to one of the discharge systems indicated below. Before pro-
ceeding with installation, check and carefully comply with the local regulations and provisions. Also, comply with the
provisions on the positioning of wall and/or roof terminals and the minimum distances from windows, walls, ventilation
openings, etc.
Manifold, ducts and flue must be suitably sized, designed and made in compliance with the current regulations. They
must be made of suitable materials, i.e. resistant to heat and corrosion, smooth on the inside and tight. In particular,
joints must be condensate proof. Also, provide for adequate condensate drainage points, connected to a trap to prevent
the condensate formed in the flues from running into the generators.
Connection
To calculate the maximum length of the fume ducts,
refer to the maximum available head indicated in
table 5.
B
Before making the flue connec-
tion fill the condensate trap
with approx. 0.5 liters of water
through the flue connections.
