Installation
Electrical connection
Fuel oil connection
Fuel oil connection
To ensure the operating safety of the
system, the fuel oil supply must be
installed carefully in compliance with
local regulations.
Important:
• Maximum pressure at the pump intake
< 1.5 bar
• Maximum vacuum pressure at the
pump
< 0.4 bar
• Before commissioning, draw oil in
using a hand pump and check the oil
lines for leaks.
All electrical installation and
connection work must only be carried
out by a suitably qualified service
engineer. All applicable regulations
and directives must be observed.
Electrical connection
• Check to ensure that the power supply
is as specified (230V, 50 Hz single
phase with neutral and earth).
Boiler fuse: > 6.3A
Electrical connection
It must be possible to disconnect
the burner from the mains using an
omnipolar shutdown device
complying with the standards in
force. The burner and heat
generator (boiler) are connected
by a 7-pin Wieland connector
1
and a 4-pin Wieland connector
2
(
not supplied
).
Fuel oil connection
The fuel oil connection must be made
via a bleed filter. The filter must be
located to ensure that it does not impair
the correct hose routing.
The hoses must not kink.
The fuel oil pipes used must be in DN6
or DN8 copper pipe.
CH: Polyamide fuel oil line DN6,
DIN 16773.
For the maximum values of the suction
lengths and heights, see the directive for
carrying out and sizing installations with
suction. This directive forms an integral
part of the elements on which ELCO
planning is based.
The suction line is passed up to 5 cm
above the tank floor in cubic tanks, and
up to 10 cm above the tank floor in
cylindrical tanks.
