2.2.10 - FLUE GAS DISCHARGE
AND AIR SUCTION WITH
DUAL DUCTS WITH 80 mm
DIAMETER
NB: The maximum allowable pressure loss,
irrespective of the type of installation, must
not exceed 50 Pa (for per IVEN 04 RTFS 24 /
CTFS 24 F) and 60 Pa (for IVEN 04 RTFS 28
/ CTFS 28 F)
For all installations with a pressure loss of the
ducts not exceeding 20 Pa, the diaphragm
supplied with the boiler must be installed insi-
de the flue gas outlet pipe (see fig. 16).
WARNING! In case the flue duct
has to cross walls or floors, or if
it is easily reachable, it is ne-
cessary to foresee a convenient
insulation of such a duct. The
flue duct, during the operation
of the boiler can reach tempera-
tures higher than 120°C.
