ASSEMBLY ONTO THE BOILER
Fix flange 2 to the boiler using 4 screws 3 interposing the insulation gasket 4 and the possible
insulating cord 5. Insert the burner in the flange so that the draught tube penetrates into the
combustion chamber by the length suggested by the boiler manufacturer. Tighten screw 1 to
lock the burner in position.
ELECTRODES ADJUSTMENT
The position of the electrodes should always be checked after any work on the combustion
head. They should be positioned according to the indications supplied in the figure below.
IMPORTANT: the ignition electrodes and the control electrode must never touch the
diffuser, the draught tube or other
metallic parts. If this were to happen they would no longer work, thus impairing opera-
tion of the burner itself.
