Select in the table the Ø of the pipework depending on the
actual length between the tank and the pump.
If H corrected for induction exceeds 4m, allow for a transfer
pump. (max. pressure 2 bars).

Assembly
Burner to boiler fixing is standardized.
If there is no hole drilled, the flange seal
can be used as a gauge.
• Position the flange and its seal on the
boiler.
The burner is assembled in position 1. If
necessary, it can be assembled in
position 2 or 3.
• Insert the burner's end piece into the
flange (penetration: see Boiler
Instructions).
• Tighten the collar while gently lifting
the burner
Fuel-oil connection
When linking the flexible hoses to
pipework, remember to allow for
removing the burner.

Electrical connection
The electrical installation and the
burner's connection must be carried out
in accordance with the standards in
force.
The burner is delivered with a 7-pole
male plug into which are connected the
230V-50Hz single-phase power supply
with ground and the thermostat. (Figure
opposite).
Note: connection of an alarm between
S3 and N and of an hour counter
between B4 and N.
