Air flow adjustment in High Flame (2nd Stage):
WARNING: When the burner is working in High Flame, the presence of oil under pressure in the hydraulic jack could
make difficult the turning of the adjusting screw 1. As a consequence, the adjustment of fuel flow rate shall be made
through said screw with the burner in Low Flame, whilst the combustion control shall be carried out once switched to
High Flame.
1 – Open thermostats TAB1 and TAB2 (see wiring diagram).
2 – Loosen locking ring nut 2.
3 – Increase or decrease fuel flow rate through the adjusting screw 1 (turn clockwise to increase and counterclockwise to
decrease).
4 – Tighten ring nut 2.
5 – Manually switch to High Flame by closing thermostat TAB1 and check combustion values.
Air flow adjustment in 3rd Flame (3rd Stage):
WARNING: When the burner is working in 3rd Flame, the presence of oil under pressure in the hydraulic jack could
make difficult the turning of the adjusting screw 3. As a consequence, the adjustment of fuel flow rate shall be made
through said screw with the burner in Low Flame, whilst the combustion control shall be carried out once switched to 3rd
Flame.
1 – Open thermostats TAB1 and TAB2 (see wiring diagram).
2 – Loosen locking ring nut 4.
