5.5.3
Blast tube length
The length of the blast tube must be selected according to the in-
dications provided by the manufacturer of the boiler, and in any
case it must be greater than the thickness of the boiler door com-
plete with its refractory.
The range of lengths available, L (mm), is as follows:
For boilers with front flue passes 13)(Fig. 13), a protection in re-
fractory material 11) must be inserted between the boiler refractory
12) and the blast tube 10). This protection must not compromise
the extraction of the blast tube.
For boilers with a water-cooled frontal, a refractory lining is not
necessary 11)-12) unless expressly requested by the boiler man-
ufacturer.

then pull the burner completely off the slide bars, after
removing the split pin from the slide bar 5).
