HYDRAULIC CONNECTIONS
The pipes that connect the tank tothe burner should be in perfect tight condition; we recommend the use of copper
or steel pipes of an adeguate diameter (see table and drawings).Fuel gate valves should be fitted at the end of
the rigid pipelines.Fit the filter to the suction pipeline after the gate valve. Connect the flexible fitting to this, which
in turn should be connected to the suction of the burner pump. Connect the flexible fitting to the return pipe after
the gate valve, and then connect it ot the burner pump return. Filter, flexible pipes and relative connecion nipples
are standard burner accessories. The pump is provided with special connection points (see drawing 0002900480,
and 0002900680) for the insertion of control instruments (manometer and vacuumeter).To ensure reliable and
silent operating conditions, the vacuum in suction should not exceed 35 cm Hg equal to 0,46 bar.Maximun suction
and return pressure 1,5 bar.
ELECTRIC CONNECTIONS
The electrical lines should be at an adeguate distance from hot parts.It is advisable to make all the connections
with flexible elecric wire. Conductor’s minimun section 1,5 mm

FITTING THE BURNER TO THE BOILER
The burner is fitted with a sliding attachment flange on the combustion head.
All the components supplied must be mounted following the burner instructions.

Insulating flange
Aluminium flange
Sheet metalring
Insulating Cord
When the burner is being mounted on the boiler it is necessary to place this flange in the right position to have the
combustion head enter the combustion chamber according to the boiler manufacturer’s requirements.
Light oil pipes must be connected to the burner after it has been properly mounted on the boiler.
