GAS SUPPLY LINE
The general gas supply situation is
illustrated here alongside The gas
train is EN 676 certified and is sup
-
plied separately from the burner.
A manual stop valve and a damper
joint must be installed as indicated
in the diagram.
If the gas train has a pressure
regulator not incorporated in a mo-
noblock valve, we recommend you
following this practical advice on the
installation of accessories on the
gas piping close to the burner:
1) To prevent large pressure drops
on ignition it is best if there is
a 1.5 to 2 m length of piping
between the point of application
of the stabilizer or pressure re-
ducer and the burner. This pipe
must have a diameter equal to or
greater than the connector to the
burner.
2) For the better working of the
pressure regulator it is advisable
to attach it to horizontal piping
after the filter. The gas pressure
regulator must be adjusted while
working at the maximum capa-
city actually used by the burner.
The delivery pressure must be
adjusted to a figure slightly lower
than the maximum obtainable.
(that which is obtained when the
regulation screw is turned almost
to the end); in the specific case,
tightening the regulation screw
the regulator delivery pressure
increases and when it is loose-
ned it decreases.
1 Boiler plate
2 Flange with insulating materials
3 Seam with insulating materials
4 Burner securing flange
5 Stud bolts, washers and nuts for fastening to the boiler
6 Nuts screws and washers to fasten flange to the sleeve
COMBUSTION HEAD ASSEMBLY
To put in place insulation flange 2, which must be posi
-
tioned between the burner and the plate of boiler 1, the
end of the combustion head must first be removed.
a) Adjust position of connector flange 4 by loosening
screws 6 so that the combustion head penetrates into
the combustion chamber the amount recommended
by the generator’s manufacturer.
b) Position seal insulation 3 on the tube unit.
c) Fasten the combustion head assembly to the boiler 1 using the stud bolts,
washers and the nuts provided 5.
d) With suitable material, completely seal the space between the tube unit of the
burner and the hole on the refractory plate inside the boiler door.
