6.12.5 Separate ducts (Ø 60mm and Ø 80mm)
Constructing outlets for separate ducts indicates the use of
the "air-smoke split pipe system". This is to be ordered sep-
arately from the boiler and when connected to the other ac-
cessories, from those listed in the table below, completes the
smoke-outlet/ combustion air inlet assembly.

NOTE:
the ducts can be reduced from Ø80 to Ø50 by using
the reducer with code 8089941, to be ordered separately, as
shown in "Fig. 17".
m
CAUTION
–
The maximum total length of the ducts
, obtained by
adding the lengths of the inlet and outlet pipes, is
determined by the load losses of the individual ac-
cessories used and
must not exceed 16.5 mm H2O
for
Edea 25 T
and
30.0 mm H2O
for
Edea 35 T
.
–
For all boiler versions, the total extension
must not
in any case exceed 25 m (inlet) + 25 m (outlet) for
ducts Ø 80 mm. For Ø 60 mm ducts, the total ex-
tension must not exceed, respectively, 18 m (suc-
tion) + 18 m (discharge) for model
Edea 25 T
and 16
m (suction) + 16 m (discharge) for model
Edea 35
T
, even if the total load loss is below the maximum
applicable level.
m
CAUTION
For model
Edea 25 T
, beyond a total load loss between
discharge and suction of
9 mm H2O
, remove the dis-
charge diaphragm as illustrated in “Fig. 27”.
For model
Edea 35 T
, beyond a total load loss between
discharge and suction of
12 mm H2O
, remove the dis-
charge diaphragm as illustrated in “Fig. 27”.
