of optional modulation kit and probe.
They are composed by: fan at high pressurisation and combustion head with adjustment at high efficiency and high
flame stability.
Compact overall dimensions and disposition rationalized of the components with accessibility facilitated for the
operations of setting and maintenance.
Available in the versions METHANE (natural gas) or L.P.G. (to specify at the order) on demand specific versions for
town gas, coal gas or biogas.
Gas train completely assembled and tested; complete of working valve with flow adjustment, safety valve, minimum
gas pressure switch and gas filter.
Complete of flange and gasket for installation on generator.
Available also special versions with INVERTER and ELECTRONIC BURNER CONTROL.

The firing rates has been obtained based on test boilers in accordance with EN267 standards and are indicative of matching the burner to the boiler.
For the correct operation of the burner, combustion chamber dimensions must be in accordance with current regulation. In case of non-compliance,
contact the manufacturer.

FLAME TUBE LENGTH
Flame tube length must be selected based on the specifications supplied by boiler manufacturer and, in any case, it
must be greater than the thickness of the boiler door included its insulation.
In case of boilers with flame inversion or front flue combustion chambers, it is necessary to insulate the area between
the flame tube and front door with refractory material. This protection material must not impede flame tube extraction.
