a two-line pump via an oil filter.
Please observe the following
points:
· Max. supply pressure at pump
< 2 bar.
· Max. suction vacuum at pump
< 0.4 bar.

· Connect the supplied oil hose to the
oil pump and pass it through the
opening of the housing.
· Position the oil filter with venting option
(recommended mesh filter: 70 µm)
in such a way that the fuel-oil hose
connections are not placed under

Regulating the oil pressure
The oil pressure and thus the burner
power is adjusted with the oil pressure
regulator 6. Turn to
right: pressure increase
–
left: pressure reduction.
–
Connect a pressure gauge at point 4
(with R1/8" thread).
Checking negative pressure
The vacuum meter for the negative
pressure check is to be connected to
connection 5, G1/8. Maximum permissi-
ble negative pressure 0.4 bar. Higher
negative pressure will cause the
heating fuel-oil to turn to gas, leading to
scraping noises in the pump.
Before initial start-up, prime the
fuel-oil pump by hand and check
all fuel-oil conduits for leaks.
