Twin outlets (ø 80)
Twin ducts can be placed in the most suitable direction
for installation requirements but special care must be
taken as regards the temperature of the installation site
and the length of the fumes
To install, follow the instructions supplied with the
In the event of installation with external discharge
sections, to calculate the maximum permitted
length without a condensate collector, refer to the
external temperature instead of that of the installation
site of the boiler.
If the appliance works at temperatures lower than
50°C (e.g.: installations with external probe), the
maximum permitted length without condensate col-
lector must be decreased by 0.85
The condensate collector can only be applied to the
fumes outlet, within 0.85 m from the boiler; connect
the trap of the condensate collector to a waste water
drain.
The fumes outlet duct must slope by 1% towards the
condensate collector.
The boiler automatically adapts ventilation according
to the type of installation and the length of the ducts.
Do not obstruct or narrow the ducts in any
If the length of the ducts is different from that
indicated in the table to the side:
- for model 26 MIX C.S.I., the sum of the lengths
of the inlet and outlet ducts must be less than
30 metres, but the length of a single duct must
not exceed 18 metres
- for model 30 MIX R.S.I., the sum of the lengths
of the inlet and outlet ducts must be less than
28 metres, but the length of a single duct must
not exceed 17 metres
- for model 35 MIX C.S.I., the sum of the lengths
of the inlet and outlet ducts must be less than
12 metres, but the length of a single duct must
not exceed 8 metres
