DISABLING THE PRESSURE REGULATOR
For the boiler to work with LPG fuel, the pres-
sure regulator on the valve group needs to be
disabled. To do so, proceed as follows:
- Screw the pressure regulator screw (1) all
the way in (fig. 3.9).
- Unscrew the pressure measurement point
screw (A) about 3 turns and connect up the
pressure gauge (fig. 3.9).
SMOOTH IGNITION
- Turn the ignition adjuster screw (B) to obtain
the correct pressure for smooth ignition (fig.
3.10).
Start up the boiler as instructed on page 21.
NOZZLE PRESSURE

supply until the pressure gauge reads out
