5.4 Operating position
5.5 Preparing the boiler
5.5.1 Boring the boiler plate
Drill the combustion chamber locking plate as shown in Fig. 13
(Tab. I). The position of the threaded holes can be marked using
the thermal screen supplied with the burner.
5.5.2 Blast tube length
The length of the blast tube must be selected according to the indica-
tions 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. 14) or flame inversion
chamber, a protection in refractory material 5) must be inserted
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. 14) is not necessary, unless expressly requested by the
boiler manufacturer.
