4.3 AIR DAMPER ADJUSTMENT,
First start-up must always be performed, adjusting screw (12), so
st
that the 1 stage air damper position pointer is beyond mark 1,
(factory setting mark 1).
To adjust, proceed as follows:
nd
Take the burner to 2

in the 4-pin plug (X4, wiring on page 8).
Fan thrust causes the air damper to go to the 2

reference to the factory setting (screw 8 on mark 3).
Loosen nut (9) and turn screw (8) to adjust 2

automatically under its own weight until maximum negative flue
pressure is 0.5 mbar.
