• Do not touch the burner with parts of the body wich are wet or when in bare feet.
• Do not pull (stretch) the mains cables and keep them well away from heat sources.
• The length of the cables used must enable the burner to be opened, as well as the boiler
door.
• After removing the packaging materials, check the content integrity and make sure that no
damages have occured during transportation. In case of doubt, do not use the burner and
contact the supplier.
• The packaging material (wooden cages, cartons, plastic bags, foam, clips, etc...) are po-
tential sources of pollution and danger, if left lying around; they should be collected up and
disposed of in the correct way (in a suitable place).
DESCRIPTION
These are forced-draught burners, with gas/air mix at the combustion head. They are suita-
ble for operating with high pressure or vacuum chambers according to relevant operational
fields. The long draught tube slides on a flange to satisfy every possible application.
These burners combine great flame stability with total safety and high performance. They
feature a regulator/stabilizer which keeps the gas/air ratio constant even in the presence of
normal causes of combustion process disturbance such as voltage fluctuations (which cause
alternations in the motor rpm), deposits on the fan, etc.
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 disconnect from the
main gas supply. The burners are equipped
with a cover which means they are particularly compact, soundproof and safeguarded.
