1.11 SETTING THE SWITCH ON AND OpERATING TEMpERATURE FOR
AppLIANCES WITH GAS SYSTEM
ADJUSTING THE GAS SYSTEM (optional)
After switching on the gas burner, make sure that it is burning correctly. If the flame has a yellow tip,
increase primary air suction. If the flames tend to move away from the burner, reduce primary air suction.
Primary air is adjusted by moving the mixer axially (Pict 7).
At the end of this operation, fasten the mixer fixing screw.
SETTING THE OpERATING TEMpERATURE
When the machine reaches its operating temperature, set the gas pressure switch as follows: loosen lock
nuts (C and D - Pict 7). Fully loosen screw (A - Pict 7): if the burner blows down, loosen the screw (B - Pict
7) by approximately two turns and then turn on the burner again.
Again, with the same screw (B - Pict 7), adjust the gas minimum corresponding to a flame about 5 mm
high and fasten the lock nut (C - Pict 7). Now slowly fasten nut A until you notice that the minimum flame
tends to increase; lastly, tighten the lock nut (D - Pict 7). To check the gas pressure switch, wait for half
an hour and make sure that operating pressure has not changed in the meantime.
