Important
Flush the system with a volume of water equivalent to at least
three times the volume of the system.
Flush the DHW pipes with at least 20 times the volume of the
pipes.
Important
Due to the presence of an aluminium heat exchanger, suitable

Connecting the heating circuit
1. Remove the dust cap on the central heating flow connection
.
2. Remove the dust cap on the central heating return connection
.
3. Fit the outlet pipe for CH water to the CH flow
.
4. Fit the inlet pipe for CH water to the CH return
.
5. In the supply directly above the boiler, establish a connection for a
overpressure valve of sufficient capacity.
6. Connect the pump to the boiler's return connection.
Always connect the boiler in a way that will guarantee the water flow
through the unit during operation. When the boiler is used in a system with
two return pipes, the return pipe must be used as a cold return. The
second return pipe is then used as a hot return. Contact us for more
information.
