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.
Oil supply
To ensure the operating safety of the
system, the oil supply must be installed
carefully in accordance with DIN 4755,
and in compliance with local regulations.
The burner is fitted with a self-priming
gear pump, which must be connected as
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.
Systems with a suction intake for EL
fuel-oil must be designed and
dimensioned in accordance with Elco
brochure, Item No. 12002182.
•
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
strain or kinked.
•
Observe the correct connection of
infeed and return hoses.
m
Before initial start-up, prime the
fuel-oil pump by hand and check
all fuel-oil conduits for leaks.
