DESCRIPTION
These are forced-draught burners with gas/air mix at the combustion head: one and two-
stage ignition versions, as well as modulating versions are available. The burners are com-
pletely automatic and equipped with controls assuring maximum safety. They can be combi-
ned with any type of chamber whether in negative or positive pressure, within the foreseen
working range.
The burners are supplied without a gas train and must therefore be completed with the train
most suitable for the system in which the burner is to be fitted. The gas train is therefore
chosen by consulting the diagram; this illustrates pressure loss as a function of mains gas
pressure, required gas delivery at the appliance and the back-pressure in the
combustion chamber. All the components can be easily inspected without having to discon-
nect from the main gas supply. The burners are equipped with a cover which means they are
particularly compact, soundproof and safeguarded.
