INSTALLATION

BOILER PLATE (A)
Drill the combustion chamber locking plate as
shown in (A). The position of the threaded holes
can be marked using the thermal screen sup-
plied with the burner.
BLAST TUBE LENGTH (B)
The length of the blast tube must be selected
D455
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:
Blast tube 10): RLS 70
• short
• long
For boilers with front flue passes 13) or flame
inversion chambers, protective fettling in refrac-
tory material 11) must be inserted between the
boiler fettling 12) and the blast tube 10).
This protective fettling must not compromise the
extraction of the blast tube.
For boilers having a water-cooled front the
refractory fettling 11)-12)(B) is not required
unless it is expressly requested by the boiler
manufacturer.

SECURING THE BURNER TO THE BOILER

D1172
(B)
Detach the combustion head from the burner,
fig. (B):
- Disconnect the oil pipes by unscrewing the two
connectors 6).
- Loosen the 4 screws 3) and remove the cover 1).
- Remove the screws 2) from the slide bars 5).
- Remove the 2 screws 4) and pull the burner
back on slide bars 5) by about 100 mm.
- Disconnect the electrode wires and then pull
the burner completely off the slide bars.
COMBUSTION HEAD CALIBRATION
D1192
At this point check, for model RLS 130, whether
the maximum delivery of the burner in 2nd stage
operation is contained in area A or in area B of
the firing rate. See page 5.
If it is in area A then no operation is required.
If, on the other hand, it is in area B:
-

-
Once this operation has been carried out (if it
was required):

unscrew the screws 1)(C) and disassemble
the blast tube 2).
Move the fixing of the rod 3)(C) from position
A to position B, thereby causing the shutter
4) to retract.
Now refit the blast tube 2)(C) and the screws 1).
secure the flange 9)(B) to the boiler plate,
interposing the thermal insulating screen
7)(B) supplied with the burner.
Use the 4 screws, also supplied with the unit,
after first protecting the thread with an anti-
locking product.
The seal between burner and boiler
must be airtight.
