INSTALLATION

BOILER PLATE (A)
Drill the combustion chamber mounting plate as shown
in (A). The position of the threaded holes can be marked
using the head gasket supplied with the burner.
BLAST TUBE LENGTH (B)
The length of the blast tube must be selected according
to the indications provided by the manufacturer of the
D455
boiler, and it must be greater than the thickness of the
boiler door complete with its insulation. The range of
lengths available, L (inch), is as follows:
Blast tube 9):
• short
• long
For boilers with front flue passes 12) or flame inversion
chambers, protective insulaton material 10) must be
inserted between the boiler refractory 11) and the blast
tube 9).
This protective insulation must not compromise the
extraction of the blast tube.
For boilers having a water-cooled front the insulation
10)-11)(B) is not required unless it is required by the
boiler manufacturer.
SECURING THE BURNER TO THE BOILER (B)
Disassemble the blast tube 9) from the burner 6) by pro-
ceeding as follows:
- Loosen the four screws 3) and remove the cover 1).
D1219
- 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 5.
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 required),
secure flange 7)(B) to the boiler plate inserting the sup-
plied gasket 8)(B). Use the 4 screws provided after hav-
ing protected the thread with an anti-seize product.
The burner-boiler seal must be airtight.
