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)
D455
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:
Blast tube 9): RL 70/M RL 100/M RL 130/M
• short
• long
For boilers with front flue passes 12) or flame
inversion chambers, protective fettling in refrac-
tory 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)(B) is not required
unless it is expressly requested by the boiler
manufacturer.
SECURING THE BURNER TO THE
D1219
BOILER (B)
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 is
contained in area B or in area C of the firing
rate. See page 4.
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)(C) and disassemble
the blast tube 5);
- Unscrew the screws 3) and remove the shutter
4);
- 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), secure flange 7)(B) to the boiler
plate interposing the supplied gasket 8)(B). Use
the 4 screws provided after having protected the
thread with antiscruffing products.
The burner-boiler seal must be airtight.
