APPLICATION OF THE BURNER TO BOILER

for model BT 75 - 100 - 120 DSPG (steel fixing flange)
1 - Boiler plate2 - Insulating gasket
3 - Burner fixing flange
4 - Elastic collar
5 - Stud bolt
6 - Locking nut with washer
7 - Nut and washer for fastening the first flange
for model BT 180 - 250 - 300 DSPG
1 Burner securing flange
2 Seam with insulating materials
3 Flange with insulating materials
4 Boiler plate
5 Stud bolts,
6 washers and nuts for astening to the boiler
7 Nuts screws and washers to fasten flange the sleeve
When tightening the flange, it is important to do it evenly
!
so that the inner faces are parallel between them. Since
the locking system is highly efficient, do not tighten the
nuts too much. During this operation (tightening of the
flange locking nuts) keep the body of the burner lifted
so that the combustion head is kept in a horizontal
position.

FUEL FEED SYSTEM

The burner pump should receive fuel from a feed circuit which has
an ancillary pump and, in some cases, a pressure regulator capable
of modifying the pressure value from 0,2 to 1 bar (see drawing N°
0002901120).
In this case, the value of the fuel feed pressure at the burner pump
(0,2 ÷ 1 bar) should not vary when the burner is at a standstill or
when it is operating at the maximum fuel delivery required by the
boiler.
Normally it is possible to realise a circuit without a pressure regulator
as shown in drawing BT 8666/3).
The feed circuit must be realized according to drawing N°
0002901120 or to drawing BT 8666/3.
The dimension of the pipelines should be in function with their length
and with the output of the pump utilized. Our instructions cover the
basic requirements needed to ensure efficient operations. All rules
and regulations existing in the country of installation should be strictly
complied with and the local fire brigade should be consulted.

ELECTRICAL CONNECTIONS

The burner's electrical connections are reduced to a minimum.
It is advisable to make all connections with flexible electric wire.
The electric lines should be at an adequate distance from hot
parts.
Make sure that the electric line to which the unit will be connected
has frequency and voltage ratings suitable for the burner.
Check that the main line, the relevant switch with fuses (essential)
and the current limiter (if required) are capable of with standing the
maximum current absorbed by the burner.
For details, refer to the specific electric diagram for every burner.
