WARNING: make sure that the feeding line is properly dimensioned and is in compliance with the local safety rules and code of practise in
the country of installation
INSTALLATION
Oil connection
OIL PRESSURE CONTROL (FEED)
The feed pressure is controlled by means
of the pressure regulator installed in the
pump and should be set at 25 bar. The
pressure regulator is operated by turning
its screw. Make sure to fill the pump with
oil prior to taking into operation.
PUMP BLEEDING
Open the feed and return stop valves and
ensure the ring line (if any) is in operation.
Reduce the oil pressure at the pressure
regulating valve. Turn on the pump by
pressing the contactor.
Check the pump for proper direction of
rotation. Check for proper oil delivery and
absence of leaks in the hydraulic oil
system. For bleeding the pump open the
pressure gauge connection, for example.
When taking the burner into operation pro
ceed by gradually increasing the pressure
to operating level (25 bar).
CHECKING THE PRESSURE
(OIL SUCTION PRESSURE)
The maximum permissible vacuum is 0,4
bar. At higher vacuum levels the fuel oil will
tend to separate air from oil which may
lead to operating trouble. In the ring line
mode of operation the recommended oil
pressure is 2 bar.
OIL CONNECTION
Hoses are used for connection to the oil
lines and stop valves. The hoses must be
installed according to the applicable
standards (relieved of tensile load, free of
distortion) to avoid kinking and exclude the
danger of breakage. Take care when
mounting the oil lines to bring their ends as
close to the burners as possible and to
arrange them in a way that the boiler door
and the burner can be swing out without
any obstruction.
Refer to the technical documentation for
the line dimensions for the feed and return
lines from the stop valves to the tank.
OIL FILTER
A filter must be installed upstream of the
pump to protect the oil pressure pump and
the hydraulic system.
INSTALLATION OPTIONS
• Two-line installation (separate feed and
return lines without delivery pump).
• Ring line system (with delivery pump and
gas-air separator).
