Securing the burner to the boiler (Fig. 7)
Disassemble the blast tube 9) from the burner 6) by proceeding
as follows:
– Loosen the four screws 3) and remove the cover 1).
– Remove the screws 2) from the two slide bars 5).
– Remove the two screws 4) fixing the burner 6) to the flange 7).
– Withdraw the blast tube 9) complete with flange 7) and slide
bars 5).
COMBUSTION HEAD CALIBRATION
At this point check, for model RL 130/M, whether the maximum
delivery of the burner in 2nd stage operation is contained in area
B or in area C of the firing rate. See page 9.
If it is in area B then no operation is required.
If, on the other hand, it is in area C:
– Unscrew the screws 1) (Fig. 7) and disassemble the blast tube
5)
– Unscrew the screws 3) and remove the shutter 4)

The length of the blast tube must be selected according to the in-
dications provided by the manufacturer of the boiler, and in any
case it must be greater than the thickness of the boiler door com-
plete with its fettling. The range of lengths available, L (mm), is as
follows:
Blast tube 9):
RL 70/M
• short
272
• long
385
For boilers with front flue passes 12) or flame inversion cham-
bers, protective fettling in refractory material 10) must be inserted
between the boiler fettling 11) and the blast tube 9).
This protective fettling must not compromise the extraction of the
blast tube.
For boilers having a water-cooled front the refractory fettling 10)-
11)(Fig. 6) is not required unless it is expressly requested by the
boiler manufacturer.
– Tighten the screws 3) on the rod 2)
– Now refit the blast tube 5) and the screws 1)
Once this operation has been carried out (if it was required), se-
cure flange 7) (Fig. 6) to the boiler plate interposing the supplied
gasket 8). Use the 4 screws provided after having protected the
thread with antiscruffing products.
The burner-boiler seal must be airtight.
