The CF/CFU models 22 and 29 can be equipped with the MY445 hydraulic kit which includes an 18 l expansion vessel, a high energy efficiency modulating heating circulating pump EEI < 0.23, a non-return valve, an air vent, a heating safety valve and a manometer. The boilers are basically supplied in chimney execution (B23). For the 22 and 29 execution horizontal forced flue connection (HOR - homologation C13) or vertical forced flue connection (VER - homologation C33) can be done by adding the kit MY921.
