5.2Adjusting for bottled gas
Undo the screw A and push the support B fully down. Remove the nozzle C with a spanner and fit the suitable one following the instructions in the tables referring to the type of gas to be used. The nozzle must not be tightened with a torque of more than 3 Nm. Return the support B to its original position, so that the nozzle C is perfectly covered.
Regulate the air flow by moving the Venturi pipe D until the distance “X” stated in point "5.5 Adjusting the primary air flow” is obtained and secure it with the screw A. When the adjustments are complete, restore the seals with wax or an equivalent material.
