2. Technical characteristics and dimensions
2.1. Technical characteristics
The boiler is equipped with a fully pre-mixed gas burner. The following models are available:
KC
: condensing boiler with sealed chamber and forced draught, supplying CH water and instant DHW;
KR : condensing boiler with sealed chamber and forced draught, supplying CH water;
Both models are available in the following heat outputs:
KC 24 and KR 24 = 23.7 kW.
KC 32 and KR 32 = 31.4 kW.
Both models are equipped with electronic ignition and ionization flame sensing device.
The boilers meet local applicable Directives enforced in the country of destination, which is stated on their data plate.
Boiler installation in a different country from specified may endanger people, animals and objects.
The main technical characteristics of the boilers are listed below:
