4.5 Blast tube length
The length of the blast tube must be selected according to the indi-
cations provided by the manufacturer of the boiler, and it must be
greater than the thickness of the boiler door complete with its insu-
lation.
The range of lengths available, L (inch), is as follows: Tab. I
For boilers with front flue passes 13)(Fig. 9) or flame inversion
chambers, protective insulation 11) must be inserted between the
boiler refractory 12) and the blast tube 10).
This protective insulation must not compromise the extraction of
the blast tube.
For boilers having a water-cooled front the insulation 11)-12) is not
required unless it is required by the boiler manufacturer.
4.6 Securing the burner to the boiler
Before securing the burner to the boiler, check through the blast
tube opening to make sure that the flame sensor probe is correctly
set in position, as shown in Fig. 11.
Now detach the combustion head from the burner, (Fig. 9):
–
remove screw 14) and withdraw the cover 15).
– Disengage the swivel coupling 4) from the graduated sector 5).
– Remove the screws 2) from the slide bars 3)
– Remove screw 1) and pull the burner back on slide bars 3) by
about 4”. Disconnect the wires from the probe and the elec-
trode and then pull the burner completely off the slide bars, af-
ter removing the split pin from the slide bar 3).
Secure the flange 9)(Fig. 9) to the boiler plate, inserting the head
gasket 6)(Fig. 9). Use the 4 screws, also supplied with the unit, af-
ter first protecting the thread with an anti-seize product.
The seal between burner and boiler must be airtight.
If you noticed any irregularities in the positions of the probe or igni-
tion electrode during the check mentioned above, remove
screw 1)(Fig. 10), extract the internal part 2)(Fig. 10) of the head
and set up the two components correctly.
