Adjustment possibilities
P
gas inlet pressure (5 ÷ 36 mbar).
PL
air pressure (0.4 ÷ 30 mbar).
PF
pressure at the combustion head (-2 ÷ + 20 mbar).
PBr
gas pressure to burner (0.4 ÷ 50 mbar).
Effective burner pressure:
pBr = PBr - PF
Effective air pressure:
pL
= PL - PF (min. 0.4 mbar)
To have stable pressures at the output of the val-
ve, the pressures in the combustion chamber
need to be constant.
WARNING
If not, the maximum and minimum outputs of the
burner will vary.

Electrical wiring
Notes on safety for the electrical wiring
The electrical wiring must be carried out with the electrical supply disconnected.
Electrical wiring must be carried out by qualified personnel and in compliance with the regulations currently in
force in the country of destination.
The manufacturer declines all responsibility for modifications or connections different from those shown in the wir-
ing diagrams.
Check that the electrical supply of the train corresponds to that shown on the identification label and in this man-
ual.
The electrical safety of the device is obtained only when it is correctly connected to an efficient earthing system,
DANGER
made according to current standards. It is necessary to check this fundamental safety requirement. In the event of
doubt, have the electrical system checked by qualified personnel. Do not use the gas tubes as an earthing system
for electrical devices.
Do not touch the device with wet or damp body parts and/or in bare feet.
Do not pull the electric cables.
The gas train is factory set to be connected according to the wir-
ing scheme shown in Fig. 5.
