Fuel supply

The burner is designed to allow entry of the flexible oil lines on
either side of the burner. 

6.1.1

Pump

The pump is supplied for use with a one pipe system.
For use on a two pipes system, it is necessary to screw the by-

 supplied with kit code 

3000970

 (Fig. 9).

Before starting up the burner, make sure that the return pipeline
is not clogged. 
An excessive back pressure (

 1 bar) would cause the damage

of the pump seal, with subsequent fuel leaks inside the burner.

Explosion danger due to fuel leaks in the pres-
ence of a flammable source.
Precautions: avoid knocking, attrition, sparks and
heat. 
Make sure the fuel interception tap is closed be-
fore performing any operation on the burner.

WARNING

The fuel supply line must be installed by qualified
personnel, in compliance with current standards
and laws.

WARNING

It is necessary to install a filter on the fuel feed
line.

WARNING

The suction line plug 1)(Fig. 9) is made of plastic.
Once removed, it must not be used again.
In single-pipe installations, the plug in the return
line must be totally in steel.
