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 natural gas burner for combu-
stion of other gases observe the following instructions.
EM 16-E - EM 16/L-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-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.
PORTATA GAS
Per quanto riguarda la portata del gas, mancando in genere la possibilità di controllo diretto
(contatore), si può empiricamente procedere attraverso i valori della temperatura fumi della
caldaia.
