OPERATION WITH DIFFERENT TYPES OF GAS
CONVERSION FROM NATURAL GAS TO B/P
A specific burner is not previewed. Should you wish to adapt a burner to a certain type of
gaseous fuel, bear in mind the following: since different conditions ca arise the use of B/P it is
necessary to eplace head assembly included in the supplied KIT.
EM 16/M-E
Loosen the screws D, remove the diffuser
ring E and replace it with another ring of
type F, which differs from type E in that
there are less gas outflow holes.
EM 26/M-E
Remove the electrodes G from the
head assembly. Loosen the screws H
and replace the head assembly I. Fit
the electrodes as per the instructions
given in the manual.
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 boi-
ler fumes temperature.
