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.

of optional modulation kit and probe.
DETAILED SPECIFICATION
Burner for gas two stages progressive (hi-low flame) or modulating (PID fully modulating) if equipped with addition of
optional modulation kit and probe; composed by:
• Fan at high pressurisation;
• Combustion head with adjustment at high performance and elevated flame stability equipped with steel blast tube and steel
flame disc;
• Flange and insulating gasket for fixing at boiler;
• Three-phase power supply;
• Safety air pressure switch to stop the burner in lock-out in case of failed or anomalous fan operation;
• Gas train with safety valve class A, adjustment valve class A and valve proving system;
• Ionisation probe for flame detection for natural gas versions;
• UV probe for flame detection for L.P.G. versions;
• IP 54 electric protection level for natural gas versions;
• IP 40 electric protection level for L.P.G. versions;
• Spherical gas valve servo-controlled; progressive start and free way passage with total opening;
• Servomotor for air shutter and for the spherical gas valve;
• Moving shutter with total closure when idle in order to reduce at the least energy losses related to boiler cooling down;
• Easy extraction of combustion head without get off the burners by bolier;
• Maximum gas pressure switch to stop the burner in lock-out in case of the gas pressure is higher then the set point value;
• Fan motor start-up with star/delta system;
• Set up for the additional specific kit that transforms burner operation as modulating i.e. the modulating kit allows to supply any
power between the minimun and the maximum value based on instantaneous loading request.
