2.1.1. INTEGRATION INTO AN OPEN CENTRAL HEATING SYSTEM
If the boiler should be connected to an open central heating system, we recommend the
system to be constructed according to the diagram 1., depending on the type of the boiler.
Connection to an open central heating system requires the implementation of an open expanding
vessel (OPC), which level has to be above the highest positioned radiator. If the expansion vessel
is situated inside a non heated room, it has to be insulated. If connected to the BIO-PEK B model,
the circulation pump can be installed on the inlet as well as on the outlet.
2.1.2. CONNECTION TO THE CLOSED CENTRAL HEATING SYSTEM
If the boiler should be connected to an closed central heating system, there
has to
be built
in a
tested safety valve
calibrated to 2,5 bar opening pressure and an expansion vessel for
closed central heating systems. Between boiler, safety valve and the expansion vessel there
should be no stop valves. It also
has to be built in a thermic valve
fixed on preinstalled
connection points of the boiler. Recommendation for the connecting to the closed central heating
system is displayed on the diagram 2., depending of the boiler's model.
