GAS BURNERS TWO STAGES
GAS X1/2CE - GAS X2/2CE - GAS X3/2CE - GAS X4/2CE - GAS X5/2CE
Gas burners two stages with: aluminum body, fan at high pressurisation and combustion head with adjustment at high
efficiency and high flame stability and protection cover with noise reduction plate.
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, electrically linked and tested; complete of two stages working valve with flow
adjustment, safety valve, minimum gas pressure switch and stabiliser filter of gas pressure.
Versions F with cover of protection in steel and specific features for the application on industrial ovens and bakery
ovens.
Complete of connector plug / socket 7 poles, flange and gasket for installation on generator.

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.
