• System shut-off valve kits with or without
inspection filter (on request). The boiler is
designed for installation of system interception
cocks to be placed on flow and return pipes
of the connection assembly. This kit is very
useful for maintenance because it allows to
empty just the boiler without having to empty
the entire system. Moreover, the version with
filter preserves the functioning characteristics
of the boiler thanks to its inspectionable filter.
• System zone control unit kit (on request). If
the heating system is to be divided into several
zones (max. three), in order to interlock them
with separate adjustments and to keep water
flow rate high for each zone, Immergas supplies
zone system kits by request.

polyphosphate dispenser reduces the formation
of lime-scale and preserves the original heat
exchange and domestic hot water production
conditions. The boiler is prepared for applica-
tion of the polyphosphate dispenser kit.
• Relay board (on request). The boiler is prepared
for the installation of a relay card that allows
to increase the features of the appliance and
therefore functioning possibilities.
• Cycloidal filter kit (on request). The magnetic
cycloidal filter is able to detect the ferrous resi-
dues present in the system's water. Thanks to
the two cocks in the kit, it facilitates mainte-
nance by cleaning the filter without having to
empty the circuit.
