Boiler body made of assembled G20 cast iron sections, generously insulated by a rockwool layer externally lined with tearproof material

Atmospheric burner with AISI 304 steel heads, electronic ignition with intermittent pilot flame and safety device detecting the ionisation current produced by the flame

Variable heat input, with two-stages operation

Flues collector with semi-integrated antirefouleur and flues test point

For smaller boilers (67÷107 kW) element with factory name "B.A.G. 21" is used, whereas for higher outputs (119÷289 kW) a bigger element (namely "LS3") is used   

Efficient operation thanks to the large heat exchange surface of the cast-iron section, and the generous insulation of the boiler body

Possibility to install the modules in cascade with a side-by-side or back-to-back layout

Steel casing painted white by anaphoresis using epoxy powder paint

Control board is preset for integration of an electronic controller
