OPERATION WITH DIFFERENT TYPES OF GAS

CONVERSION FROM NATURAL GAS TO B/P
A specific burner is not previewed.
Should you wish to convert the burner from natural gas to other types of gas, bear in mind that it is necessary
to move the ring nut A situated on the supply pipe B towards the diffuser C, so as to close the gas outlet holes
in models JM 3/JM 6 and to reduce their section in model JM 9.
GAS DELIVERY
As far as the gas delivery is
concerned, considering that in
general it is not possible to
carry out a direct check up
(meter) it is possible to proceed
empirically using the values of
the boiler fumes temperature.
