Blast tube length
The length of the blast tube must be selected according to the
indications provided by the manufacturer of the boiler, and in any
case it must be greater than the thickness of the boiler door
complete with its fettling. The range of lengths available, L (mm),
is as follows:
Tab. G
For boilers with front flue passes 13) or flame inversion
chambers, a protection in heat-resistant material 11) must be
inserted between the boiler refractory 12) and the blast tube 10).
This protection must not compromise the extraction of the blast
tube.
For boilers with a water-cooled front piece, a refractory lining 11)-
12)(Fig. 11) is not necessary, unless expressly requested by the
boiler manufacturer.
5.5.3
Securing the burner to the boiler
Separate the combustion head from the rest of the burner
(Fig. 11):
disconnect the light oil pipes unscrewing the two unions 4).
remove screw 14) and extract the cover 15).
remove screws 2) from the two slide bars 3).
remove screw 1) and pull the burner back on slide bars 3) by
about 100 mm.
Disconnect the wires of the electrodes and then pull the
burner completely off the slide bars, after removing the split
pin from the slide bar 3).
ATTENTION
The burner is set up to operate only in
positions
1, 2, 3
and
4
(Fig. 9).
Installation
1
is preferable, as it is the only
one that allows the maintenance operations
as described in this manual.
Installations
2, 3
and
4
permit operation but
make maintenance and inspection of the
combustion head more difficult.
DANGER
Any other position could compromise the
correct operation of the appliance.
The installation

is prohibited for safety
reasons.
