11. Lifting unit 

 

A lifting unit (pic. 12) has a gear pump with its own electric engine, a flange to connect fine fuel 

filter and a set of flexible tubes one of which has a sieving fuel inlet on the end.  

 

  

 
 
 
 
 
 
 
 
 

 
 

 

Pic. 12 Lifting unit with a fine fuel filter 

 

Instead of a fine fuel filter any car oil filter with standard rim diameter and screw can be used. 

Cargo vehicle filters are more long-lasting because of their large volume. 

Before  installing  an oil filter fill  it  with fuel  and put  some  on  a  rubber  o-ring. Assembling and 

dismantling the filter should be done with a catch hook that can be bought in a car parts shop. 

 

The lifting unit has to be installed on the main fuel box, if it is placed in the room next to the 

burner, or on the waste fuel box next to it, if the main box is not placed in the room. In the latter 

case the fuel flow from the main box to the waste one has to be organized. 

Electric connection of the lifting unit is done according to the burner electric diagram (pic.10 and 

11) 

 

 

 

The base box of the lifting unit must be grounded! 

 

 

NB!

 To keep fuel clean, a sieving fuel inlet needs to be installed so that its lowest part 

was no less than 15-20 cm from the bottom of the fuel box. It will prevent water and 

solid dregs from getting into the burner. 

 
It is better to have a floating fuel inlet. For this purpose, any suitable float (sanitary or an empty 

plastic bottle) can be adjusted to it. It is recommended to use a limiting chain or wire which will 

not let the fuel inlet to go down to the bottom of the box. (pic. 13)
