INSTALLATION
!
THE BURNER MUST BE INSTALLED
IN CONFORMITY WITH LEGISLATION
AND LOCAL STANDARDS.
OPERATING POSITION (A)
!
The burner is designed to work only in
the positions
1 , 2 , 3 and 4 .

Installation 1 is preferable, as it is the
only one that allows performing maintenance
operations as described in this manual. Instal-
lations
2 , 3 and 4 permit operation but make
maintenance and inspection of the combus-
tion head difficult, page 14.
Any other position could compromise
the correct working of the appliance.

Installation 5 is prohibited for safety
reasons.
BOILER PLATE (B)
Drill the combustion chamber locking plate as
shown in (B). The position of the threaded holes
can be marked using the thermal screen sup-
plied with the burner.
BLAST TUBE LENGTH (C)
The length of the blast tube must be selected
according to the indications 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. The range of
lengths available, L, is as follows:
