3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.
3.1 WORKING POSITION
The burner is designed for operation in positions 1 and 2 only.
Installation 1 is the preferred option as it is the only one that enables maintenance to be performed as described
later on in this manual.
Operation is possible with installation option 2 though maintenance cannot be performed with the burner
connected to the boiler. Note that any other installation position is likely to hinder the unit's proper operation.
Installations 3, 4 and 5 are prohibited as safety is compromised.
