out by a suitably qualified service
engineer. VDE and EVU (RGIE-AREI
for Belgium) rules and regulations
must be observed when doing so.
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.
m
Before initial startup, prime the
fuel-oil pump by hand and check
all fuel-oil conduits for leaks.

Checks before startup
The following points must be checked
before first use.
·
Correct installation of burner as per
instructions supplied.
·
Correct pre-adjustment of burner as
per data given in table of settings.
·
Adjustment of burner head, the
correct nozzle must be installed. The
heat generator must be installed and
ready for operation, the operating
instructions of the heat generator
should be observed.
·
All electrical connections must be
carried out correctly.
·
Heat generators and heating systems
are to be filled sufficiently with water,
with circulation pumps in operation.
·
Temperature controllers, pressure
regulators, low water-level detectors
and any other safety or limiting
devices that might be fitted are
correctly connected and in operation.
·
Exhaust conduits must be
unobstructed, draught stabilizers - if
fitted - must be functioning.
·
Ensure that there is an adequate
supply of fresh air.
·
The heat dissipation system must
function correctly.
·
Fuel storage tanks must be filled.
·
Fuel conduits must be correctly fitted,
checked for leaks and purged of air.
·
A standard-compliant measuring
point must be available for the
metering of emissions, the exhaust
conduit upstream of this measuring
point must be free of leaks in order to
prevent outside air from causing
measurement errors.
