2.6 Fume ducts

THE BOILER MUST BE INSTALLED IN PLACES THAT MEET THE FUNDA-
B
MENTAL REQUIREMENTS FOR VENTILATION. OTHERWISE THERE IS A
DANGER OF SUFFOCATION OR INTOXICATION.
READ THE INSTALLATION AND MAINTENANCE INSTRUCTIONS BEFORE
INSTALLING THE UNIT.
ALSO FOLLOW THE DESIGN INSTRUCTIONS.
IN CASE OF PRESSURES ABOVE 200 Pa INSIDE THE FUME EXHAUST PI-
PES, CLASS "H1" FLUES MUST BE USED.
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.

Before installation, make sure the maximum permissible length has not been exceeded, by means of a simple calculation:
1. Establish the layout of the system of split flues, including accessories and outlet terminals.
2. Consult table 3 and identify the losses in m
position.
3. Check that the sum total of losses is less than or equal to the maximum permissible length in table 2.
