Fuel-oil supply
Careful installation of the fuel-oil supply
to DIN 4755 standards, along with full
observance of any local rules and
regulations that might apply, is
necessary in order to ensure the safe
operation of the system. The burner is
equipped with a self-priming geared
pump, which should be connected via a
ventilation filter to function as a
two-pipe pump.
Please observe the following points:
· Max. admission pressure at pump < 2bar.
· Max. suction vacuum at pump < 0,4bar.

· Connect the fuel-oil hoses supplied to
the fuel-oil pump and lead in via the
lateral opening in the housing.
· Locate fuel-oil filter with venting
function (recommended mesh width :
70 µm) in such a way as to ensure
that the fuel-oil hose connections are
not placed under strain or kinked.
· Observe the correct connection of
infeed and return hoses.
All electrical installation and
connection work MUST be carried
out by a suitably qualified service
engineer. VDE and EVU rules and
regulations must be observed when
doing so.
