Fume Ducts - Ferroli FORCE W Instructions D'utilisation, D'installation Et D'entretien

2.6 Fume ducts

THE BOILERS MUST BE INSTALLED IN ROOMS THAT MEET THE FUNDA-
B
MENTAL VENTILATION REQUIREMENTS. OTHERWISE THERE IS A DAN-
GER OF ASPHYXIA OR POISONING.
READ THE INSTALLATION AND MAINTENANCE INSTRUCTIONS BEFORE
INSTALLING THE UNIT.
ALSO RESPECT THE DESIGN INSTRUCTIONS.
IN CASE OF PRESSURES EXCEEDING 200 Pa INSIDE THE FUME EXHAUST
PIPES, THE USE OF CLASS "H1" FLUES IS MANDATORY.
Important
If installation of the unit is type B23,, with combustion air intake from the installation room and fume evacuation by
means of a fan (operation with pressurized flue), it must be connected to one of the exhaust systems indicated below.
Before proceeding 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, ven-
tilation 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.
Fume pipes connection
Before installation, make sure the maximum permissi-
ble head has not been exceeded, by means of a sim-
ple calculation:
1. Completely define the layout of the flue system.
2. Consult the table 4 and identify the losses of each
component.
3. Check that the sum total of losses is less than or
equal to the maximum permissible head in table 4.
