GENERAL INSTRUCTIONS
The EXA series is a highly-efficient boiler for domestic and industrial heating, suitable for operation with
burners of liquid and/or gas fuels.
The boiler body is comprised of cast iron elements, assembled with steel bicones and ties, whose profile has
been specially cured with an optimal distribution of flaps allowing high thermal effectiveness and consistently
high energy savings.
The aesthetic and complete insulation are ensured by an elegant instrument panel, a painted casingt pressure-
assembled and a glasswool lining of considerable thickness, reducing the dispersion of heat into the atmos-
phere to a minimum.
