Always check that the combustion head dimensions are compatible with the burner nozzle.
To connect it to the gas supply ramp, consult the burner technical sheets and select the fittest
model on the basis of the thermal power and of the fuel pressure available in the network. The
mentioned documents also specify the relevant fittings, if any.
The availability of new burner models is in continuous evolution. For specific needs, consult the Manufacturer.
ATTENTION
If the unit operates on gas, the EC certification is valid only if it is combined with the burner
indicated in the table. For different combinations, consult the Manufacturer.
The minimal gas supply pressure should be such as to offset the friction losses of the supply ramp
increased by an approx. 30% safety coefficient.
The gas supply pressure should always be stable and never exceed the max. value specified in
the instructions of the burner.
COMBUSTION AIR
The warm air heater should be installed in compliance with the Regulations in force and it should be used only
in an adequately ventilated room.
Check that the combustion air inlet is always free from any obstacles (leaves, sheets of paper, nylon pieces,
etc.).
Proper air openings should be made, in compliance with the relevant Regulations.
