8 - OIL CONNECTION
A double tube is used for the fuel connection to the
burner. It is possible to make a monotube connec
-
tion. - Please refer to the technical instructions sup-
plied with the burner.
Note :
- Fitting an oil filter to the burner oil inlet is recom-
mended.
9 - ELECTRICAL CONNECTION
- The electrical connection and all the equipment
used to make this connection must be in confor
-
mity with the codes of practice in force, particular-
ly with French standard NF C 15-100,
- the premises must be suitable in terms of boiler
protection (IPX0D),
The boiler is connected to the network at the con-
nection terminal block (4) located behind the control
panel (1) (
fig. 48 - page 31).
- power supply: 230 V - 50 Hz (single phase),
- earth connection obligatory,
- the electrical supply must contain a cut-out switch
(preferably bipolar), with a circuit-breaker or 6A
fuse.
- respect the Live-Neutral polarities.
The electric connection of the boiler is carried out in
the connection terminal box (item no. 4) located
behind the control panel.
- remove the top of the casing (item no. A),
- unscrew the 2 screws (item no. K) of the protec-
tion plate (item no. 9),
- remove the terminal box protection plate (item no.
9),
- make the electrical connection to the terminal box
(item no. 4),
- be sure to pass the electrical cables and sensor
cables through the channels provided for this
purpose (item no. O).
The sensor cables must not pass throu-
gh the same duct as the 230V cables.
The different electrical connections
vary depending on whether the installa-
tion conains a regulator or not.
Remarks:
- Digital regulation is the best method of regulation.
-A 2
nd
heating circuit can be connected in all the
cases below (see dotted lines).
- With underfloor heating, a safety thermostat
(TLS) is to be installed in the flow of the 2
nd
cir-
cuit output.
- All the thermostats are represented on heat re-
quest. The various components external to the
appliance (valves, circulating pumps, etc.) will be
connected to the earth on the boiler terminal box.
