Electrical connection
·
Check to ensure that the power
supply is as specified (230 V, 50 Hz)
Burner fuse rating: 10A
Electrical plug connection
The electrical plug-and-socket
connection, burner and heat generator
(boiler) are linked via one 7P. and one
4P. plug-and-socket connection.
The connection cable is fed through the
connection clamp and secured.
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.
For details of project planning and
dimensions of systems with suction
installation for EL heating fuel-oil,
please be sure to refer to ELCO
brochure no: 12002182.
·
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.
