2.8 - Gas connection
The connection of the START CONDENS Kis boiler to the gas supply
must be carried out in the respect of current installation standards.
Before carrying out the connection, it is necessary to ensure that:
• The gas type is suitable for the appliance
• The piping is thoroughly clean.
9 The gas feeding system must be adapted to the boiler output
and must be equipped with all the safety and control devices pre-
scribed by the current standards. The use of a filter of adequate
dimensions is recommended.
9 Once the installation is done, check that the junctions carried
out are sealed.
2.9 - flue gas outlet and combustion air suction
9 The maximum lengths of the ducts refer to flue systems availa-
ble in the catalogue.

9 The straight length measurement is inclusive of the first bend
(boiler connection), terminals and joints; with the exception of
the vertical coaxial duct Ø 60-100 mm, where the straight length
does not include the bends.
9 It is compulsory to use specific pipes.
9 The non insulated flue gas outlet pipes are potential sources of
danger.
9 The use of a longer pipe causes a loss of output of the boiler.
9 Make sure the flue gas discharge pipe is tilted 3° towards the
boiler.

The appropriate adaptor kit must be installed for this configuration.
The concentric pipes can be fitted in most suitable direction in rela-
tion to installation requirements. For installation, follow the instruc-
tions supplied with the specific kit for condensing boilers.
