Warning
The boiler must be installed by a qualified installer in accordance
with local and national regulations.
6.2.1

Rinsing the system

The installation must be cleaned and flushed in accordance with BS 7593
(2006) and BSRIA BG 33/2014.
Before a new boiler can be connected to an existing or new system, the
entire system must be thoroughly cleaned and flushed. This step is abso­
lutely crucial. The flushing helps to remove residue from the installation
process (weld slag, fixing products etc.) and accumulations of dirt (silt,
mud etc.)
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 a
volume of water equivalent to at least 20 times the volume of the
pipes.
Important
Due to the presence of an aluminium heat exchanger, suitable
chemicals and the correct use of these chemicals should be dis­
cussed with specialist water treatment companies.
6.2.2

Connecting the heating circuit

1. Remove the dust cap on the CH flow connection terminal.
2. Remove the dust cap on the central heating return connection.
3. Attach the outlet pipe for central heating water to the central heating
flow.
4. Attach the inlet pipe for central heating water to the central heating
return.
5. Connect a safety valve to the boiler's flow connection.
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 sec­
ond return pipe is then used as a hot return. Contact us for more informa­
tion.
