Fuel oil filters
Problem
Possible reason
Repair
Oil cannot be sucked in
or steady flow keeps
being interrupted
Small leaks at the screw
connections between
the withdrawal fitting at
the tank and the burner
allow air to get into the
suction line. This is also
the case during idle
times until the vacuum
no longer exists. This
generates an air cush-
ion in the suction line
Use cylindrical screwed
pipe connections at the
housing and seal them
with flat copper gaskets
(air-tight)
Use a stiffener in the
case of soft or semi-soft
copper pipes
Check all sealing sur-
faces for damage
Close the shut-off valve
at the withdrawal fitting
and perform a vacuum
test (at least 0.6 bar) at
the flow connection of
the oil vent
Burner pump does not
generate a sufficient
vacuum
Perform a suction test at
the pump. The pump
must generate a pres-
sure of at least -0.4 bar
