Twin ducts can be placed in the most suitable direction for instal-
lation requirements but special care must be taken as regards the
temperature of the installation site and the length of the fumes duct.
To install, follow the instructions supplied with the kit.

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 len-
gth without condensate collector must be decreased by 0.85
metres.
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 conden-
sate 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 way.
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 models 30 MIX C.S.I. - 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. - MIX R.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.
