ADJUSTMENTS IN MAIN BURNERS
Air shutter adjustments are preset at the factory. These adjustments may need to be redone and/or fine tuned by
the installer. These adjustments are normal and can be regulated and fixed with a screw by adjusting the air shutter.
In the “Burners technical data” table are the approximate values of parameter “h” (air shutter). The volume flow of
primary air (air shutter) must be regulated so that the flame does not tend to come away from the burner when it is
cold or backfire when the burner is hot, The flame should be almost all blue all the time. Lowest setting adjustment
can be made by turning the bypass screw by a 1/4 of the turn at time, see table below for values, note that for LPG
the screw position should be closed.
GAS A = Natural gas (pressure at the outlet of the regulator) = 10 mbar (4 inch water)
GAS E = Propane gas (pressure at the outlet of the regulator) = 24.9 mbar (10 inch water)
