CONDITIONS FOR CORRECT
INSTALLATION
Before proceeding with the installation make certain that:
• The chimney (cross section and height) complies with the boiler
manufacturer's instructions and legal provisions.
• When it is necessary to cover the combustion chamber with
refractory material (if the boiler type requires it), perform this
operation by following the instructions provided by the boiler
manufacturer.
• The burner power supply line must be made according to the
wiring diagram provided by us and any electrical connections
on the burner must be suitable for the power supply voltage.
• Fuel pipes must be laid out according to our diagrams.
• The nozzle or nozzles fitted on the burner must be suitable for
the boiler capacity. If necessary, replace them with suitable
ones. In no case should the quantity of fuel delivered exceed
the maximum amount required by the boiler and the maximum
amount allowed for the burner. Remember that the combustion
head is designed for nozzles with a 45° spray angle. There are
only special cases where nozzles can be fitted with a different
spray angle; in these cases, however, make sure that the nozzle

BURNER CONNECTION TO THE BOILER

1 Boiler plate
2 Flange made of insulating material
3 Insulating cord
4 Burner coupling flanges
5 Stud-bolts, washers, and nuts for anchorage to boiler
6 Sleeve to flange retaining nuts, screws and washers
HEAD UNIT ASSEMBLY
Remove the combustion head end part to insert the insulating
flange 2 between the burner and the boiler plate 1.
• Loosen the screws 6 to adjust the position of the
connection flange 4, so that the combustion head
penetrates the furnace as recommended by the generator
manufacturer.
• Position the insulating seal 3 on the sleeve.
• Fix the head unit to the boiler 1 using the supplied stud-
bolts, washers and nuts 5.
• Use suitable material to completely seal the space
between the burner sleeve and the hole on the refractory
material inside the boiler door.
with a different spray angle will not cause any problems (flame
separation, disc or combustion head fouling, violent ignition,
etc.).
• When removing the protective plastic cap from the nozzle seat
be careful because if the sealing surface is indented (a slight
scoring would be enough) it will cause fuel dripping.
• Make certain that the burner head penetrates into the combustion
chamber according to the instructions of the boiler manufacturer.
• Before connecting the flexible pipes, remove the protective
plastic caps inserted in the pump fittings.
