1 GENERAL
The boilers of the MONOLITE series have a horizontal through-flame combustion chamber and a vertical
condensing section of a special design, in stainless steel type AISI 316 Ti. These elements are immersed in
water contained in a horizontal boiler drum with a vertical column to which the system inlet and outlet con-
nections are fitted.
These boilers reach very high efficiency levels (nearly 108% referred to the Lower Calorific Value LCV) as
the flue gases not only are released at a temperature little higher than that of the system return water, but
also a large part of the water vapour contained in the flue gases is condensed, recovering the latent heat of
condensation.
The particular flame path (through the combustion chamber without inversion) limits as much as possible the
formation of Nitrogen Oxides (NOx) that form when the flame remains at high temperature in the combustion
chamber for long periods.
The MONOLITE series boilers place no limit on the return water temperature, and reach the highest per-
formance when used with floor panel heating systems in which the return temperature is lower than 58C. At
higher temperatures, condensation does not occur and so the recovery of the latent heat contained in the
water vapour, present in the flue gas, is impossible. The efficiency of the boiler remains in any case high
(97%) even with traditional high-temperature heating systems (

t 80/65° C ) .
The very high efficiency due to the complete recovery of the heat content of the fuel and to heavy
thermal insulation of the boiler, using high density glass wool, allow classification of the MONOLITE
series boilers as “4-Star - very high efficiency” as to the Efficiency Directive 92/42/CEE..
