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. 12) or flame inversion
chambers, protective fettling in refractory material 5) must be in-
serted between the boiler fettling 2) and the blast tube 4).
This protective fettling must not compromise the extraction of the
blast tube.
For boilers having a water-cooled front the refractory fettling 2)-
5)(Fig. 12) is not required unless it is expressly requested by the
boiler manufacturer.
4.6
Securing the burner to the boiler
Prepare an adequate system of hoisting by hooking onto the rings
3)(Fig. 12).
Slip the thermal protection (standard equipment) onto the
blast tube 4).
Place entire burner on the boiler hole (arranged previously,
see Fig. 11, and fasten with the screws given as standard
equipment.
4.7
Accessibility to the interior of the combustion head
Proceed as follows:
open burner at hinge (Fig. 13) after removing the 4 screws 1).
Disconnect the wires 2) from the electrodes.
Disconnect the oil pipes by unscrewing the two connectors 3).
While unscrewing, some fuel may leak out.
Unscrew the under part of the elbow 4) until it comes free of its
slot.
Extract the internal part 5) of the combustion head.
