Connecting the discharge pipe to the condensate collector box siphon
Connect the siphon discharge, located below the boiler, to the discharge of the home using a flexible pipe in accordance with
prevailing standards and regulations. The discharge pipe must have a gradient of at least 3 cm per metre, with a maximum
horizontal length of 5 metres.
Warning
Fill the water siphon before starting the boiler to avoid combustion products from the boiler being emitted into the
room.
Caution
Do not drain condensation water into a roof gutter at any time.

Gas connection
Caution
Close the main gas cock before starting work on the gas pipes. Before installing, check that the gas meter has
sufficient capacity. To do this, you should keep in mind the consumption of all domestic appliances. If the capacity
of the gas meter is insufficient, inform the local energy supply company.
Remove the protective plug on the boiler gas fitting.
Connect the gas connection pipe to the boiler's gas inlet fitting.
Fit a gas isolation valve on this pipe, directly under the boiler.
Caution
Carefully tighten the boiler gas fitting (maximum torque 30 Nm).
Important
Connect the gas pipe in accordance with prevailing standards and regulations. Make sure that no dust, water etc.
enters the gas pipe. In this case, blow inside the pipe, shaking it vigorously. It is recommended to install a suitable
filter on the gas pipe to prevent the gas valve from being clogged.
