4.5 Preparing the boiler
4.5.1 Boring the boiler plate
Drill the combustion chamber locking plate as shown in Fig. 11.
The position of the threaded holes can be marked using the ther-
mal screen supplied with the burner.
4.5.2 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 in any case
it must be greater than the thickness of the boiler door complete
with its fettling.
For boilers with front flue passes 1)(Fig. 18 on page 23) or flame in-
version chamber, a protection in refractory material 5) must be in-
serted between the boiler fettling 2) and the blast tube 4).
The refractory can have a conical shape (minimum 60°).
This protective fettling must not compromise the extraction of the
blast tube.
For boilers with a water-cooled front piece, a refractory lining 2)-
5)(Fig. 18 on page 23) is not necessary, unless expressly request-
ed by the boiler manufacturer.
