Installation
Assembly
The burner is secured on the boiler with
the flange supplied. Holes are drilled as
shown in the drawing. The flange gasket
can be used as a template.
• Mount the flange and its gasket on the
boiler. Check for leaks.
The burner is installed in position
1
.
If necessary, it may be installed in
position
2
or
3
.
• Insert the connecting nozzle into the
flange (insertion: see boiler manual).
• Tighten the clamp, raising the burner
slightly.
To fit it in position
2
, reverse the
display. To do this while the burner is
operating:
Hold buttons
BP1
and
BP2
down at
the same time, until you notice a
change.
Fuel oil connection
When connecting R 3/8 hoses to the
piping, allow for the burner to be
removed.
Two-line connection
The illustration opposite allows the
diameter (Ø) and the length (L) of the
piping to be determined from the suction
height (H+) or load (H-) (for fuel oil with
a density of 0.84, to a temperature of
10°C, in an installation which includes
one valve, one non-return valve and four
elbows, at the most).
Single line connection
(for a charged tank only)
Remove the return hose, remove the
connection and the bypass cap. Plug it
using a cylindrical cap and a seal.
Electrical connection
The electrical setup and the burner
connection must be performed in
compliance with the standards in force.
The burner is supplied with a 7 pin male
connector, to which the single-phase
230V-50Hz power supply with earth and
the thermostat are connected (diagram
opposite).
NB: External connection of an alarm
between S3 and N and an hour meter
between B4 and N.

e.g.: altitude 1100m. Theoretical H = 1m actual H 2m.
Corrected H for suction 2 + 1 = 3m
Corrected H for charging 2 - 1 = 1m
Choose the Ø of the piping from the table, based on the
length expanded between the tank and pump.
If corrected H for suction exceeds 4m; make provisions for
a transfer pump (max. pressure 2 bar).
