3. TECHNICAL fEATURES AND DIMENSIONS
3.1. Technical features
The boiler is equipped with a fully pre-mixed gas burner. The following model is available:
- KC: condensing boiler with sealed chamber and forced draught, supplying CH water and for instant DHW production;
This version is available with two power ratings:
- KC 24:
with heat input of 24.9 kW
- KC 28: with heat input of 27.9 kW
Both models are equipped with electronic ignition and ionisation flame sensing device.
The boilers meet local applicable Directives enforced in the country of destination, which are stated on their rating plate.
Installation in any other country may be a source of danger for people, animals and property.
The key technical features of the boilers are listed below:
