Installation
5.4 Operation position
The burner is designed to operate only in the positions 1 , 2, 3 and
4 .
Installation 1 is preferable, as it is the only one that allows the
maintenance operations as described in this manual.
Installations
2 , 3 and 4 permit operation but make maintenance
and inspection of the combustion head more difficult.
Any other position could compromise the correct operation of the
appliance.
Installation
5 is prohibited for safety reasons.
5.5 Removal of the locking screws from the shutter
5.6 Preparing the boiler
5.6.1 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.
5.6.2 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 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.
