OIL SUPPLY
System construction and installation must be in accordance with
DIN 4755. Local regulations must be followed.
Oil pipes must be brought sufficiently close to the burner so that the
tubes can be connected without strain. On the aspiration side of the
line, fit a filter with a quick closing valve. Install a check valve on the
return line.
The Burner can operate with a 1 or 2 line system.
In series, the burner is designed to operate with a two-line system.
The vacuum in the aspiration line should not exceed 0.4 bar.
Refer to the ACV BMV1 and BMV2 burner manual
supplied with them.
