BURNERS
The burners that can be installed on the
ASX
boilers must be CE marked according to European Directives:
–
Gas Directive 2009/142/EC
–
Electromagnetic Compatibility Directive 2014/30/EU
–
Low Voltage Directive 2014/35/EU
–
Machinery Directive 2006/42/EC (for liquid fuel burners)
Since the optimal operation of the boiler depends on the correct selection of the burner and its adjustment, find below some
points to take into account:
–
The burner to be combined with the boiler must be of two-stage or modulating type; so that excessive flow temperature
variations can be avoided.
–
The burner firing range must include the point of operation of the boiler (flow rate-back pressure in combustion chamber
considering also any resistance/draught of the smoke duct)
–
the length of the combustion head must be adequate to the penetration into the combustion chamber provided by ICI and
shown in the table
–
the length and shape of the flame must be suitable to the flame inversion combustion chambers. The burner manufacturers
have this information as they are required by certification.
