GAS X5/MCE-EL
Burners for gas modulating (PID fully modulating) if equipped with addition of optional modulation kit and probe.
Composed by: die-cast aluminum body, fan at high pressurisation, 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 operations of setting and
maintenance.
Available in the versions METHANE (natural gas) or G.P.L. (to specify at the order) on demand specific versions for
town gas, coal gas or biogas.
Gas train complete of: one-block valve class A (1st stage slow opening + safety), minimum gas pressure switch,
filter, stabiliser of gas pressure.
Complete of flange and gasket for installation on generator.
Electronic control box Lamtec BT3 with microprocessor and two servomotors for air and gas adjustment.
Interactive set-up LCD display.
The fuel / combustion air curve, with electronic cam device, is fully exploited, guaranteeing excellent
performance in terms of accuracy and speed, even during the calibration phase. A microprocessor monitors
the different stages of the process and allows the correct repetition of the sequences of operation.

The firing rates has been obtained based on test boilers in accordance with EN676 standards and are indicative of matching the burner to the
boiler. For the correct operation of the burner bruciatore, 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.
