1.14.5 Hydraulic connections scheme with closed expansion system for the FI-GS boilers
with accumulator, cooling coil and 4 ways valve.
1.14.6 Hydraulic connections with open expansion tank for the FI-GS boiler with accumulator,
accumulator tank, cooling coil, re-circulation pump with thermostat controlled (this type with
an accumulation tank is recommended if the boiler operates more than 50% on wood manual
feeding)
1.14.7 Hydraulic connection scheme with closed expansion tank for the FI-NSP boilers with
accumulator, accumulator tak, cooling coil and 4 ways valve (this type with accumulating tank
is recommended if the boiler operates more than 50% on wood manual feeding)
