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.
