1.1.16. INSTALLATION MODES
For this type of boiler are available the following
fumes discharge configurations: B23P, B33, C13,
C33, C43, C53, C63, C83 e C93 (see Fig. 1).
› B23P-
Indoor suction and outdoor
discharge.
› B33- Indoor suction and fumes exhaust duct
discharge.
› C13- Concentric wall discharge. The tubes can
be split but the outputs must be concentric or
close enough to each other to undertake similar
wind conditions (within 50 cm).
› C33- Roof concentric discharge. Outputs as for
C13.
› C43-
Discharge and suction in common
separated fume exhaust ducts, subjected to
similar wind conditions.
› C53-
Roof or wall separated discharge and
suction, in areas with different pressures. The
suction and discharge inlets should not be
placed on opposite walls.
› C63-
Discharge and suction systems made
with tubes commercialized and certificated
separately.
› C83-
Discharge in single or common fume
exhaust duct and wall suction system.
› C93- Discharge through an intubated conduct to
a vertical terminal. The technical compartment
in which is housed the discharge, also plays the
role of combustion air suction duct through the
gap that will be formed.
DISCHARGE OF COMBUSTION PRODUCTS FOR
C63-TYPE DEVICES
Each flue fitting has a resistance factor that
correspond to a certain tube length (of the same
diameter) expressed in metres. These data are
provided by the flue fittings distributor. Each
boiler has a maximum allowed resistance factor,
expressed in Pascal, corresponding to the
maximum tubes length with any type of Kit. The
maximum allowed strength factor of the ducts
installed in this boiler, that should not be exceeded,
is specified in the ‘TECHNICAL SPECIFICATIONS’
section. All this information allow us to perform
the necessary calculations to check the
possibilities of realizing the most diverse flue
fitting configurations.
The ducts must be certified for this specific use and
for a temperature greater than 100 °C.
