6 Installation
6.1 General
Warning
The boiler must be installed by a qualified installer in accordance
with local and national regulations.
6.2 Hydraulic connections
6.2.1 Rinsing the system
Installation must be carried out in accordance with the prevailing
regulations, codes of practice and the recommendations in this manual.
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
absolutely 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 at least 20 times the volume of the
pipes.
6.2.2 Connecting the heating circuit
Important
For C 630 ECO: the properties described and the instructions
apply to each boiler module.
1. Remove the dust caps from the CH flow connection and CH
return connection .
2. Fit the outlet pipe for CH water to the CH flow .
3. Fit the inlet pipe for CH water to the CH return .
4. Connect a safety valve to the boiler's flow connection.
5. 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 (if connected) is then used as a hot return. Contact us
for more information.
The flow pipe is fitted with the following components:
1 Immersion tube for a temperature sensor for an external control
(½").
2 Air vent (⅛").
3 Safety valve connection (1½").
4 Pressure gauge (½").
5 Flow sensor (M6).
6 High-limit thermostat (M4).
