If any electrical connection is used other than that recommended by Enertech, there may be a risk of 

damage to property and personal injury.

3.2  Delivery inspection

Make sure everything is delivered and the goods have not been damaged 

during transit. If something is wrong with a delivery, report it to the supplier. 

Transport damage must be reported to the shipping company.

3.3  Preparing for installation

Check that the burner’s dimensions and capacity range are suitable for the 

relevant boiler. The power data on the rating plate refers to the burner’s 

minimum and maximum power.

3.4  Oil distribution

In order to achieve good reliability, it is important that the oil distribution 

system is designed correctly.

Take the following into account:

-

Selection of pipe diameter, pipe length and height difference; see 
Pump instruction.

-

Pipelines are to be laid with the fewest possible number of glands. 

-

The pipes are to be laid so that the oil supply hoses are not subjected 
to tensile stresses or become excessively bent when the burner is 
swung out or removed for servicing.

-

The oil filter should be installed so that the filter cartridge can easily be 
replaced or cleaned. 

-

Parts in contact with oil must be selected in materials that are capable 
of withstanding the medium’s physical properties.

-

When installing oil hoses, check that the inlet and return hoses are 
fitted to the appropriate connection on the oil pump. The hoses must 
be located so that they do not bend or become subject to tensile 
load. 

-

Bleed the oil system. The oil pump/oil preheater may be damaged if 
run dry. The vacuum in the suction line should not fall below 0.3 bar 
during start-up.

!

Be sure to fill the 
burner oil system 
before starting it for 
the first time.

3.5  Electrical connection

•  Before work on the electrical connection, the current must be 

disconnected so that the installation is isolated.

•  Electrical connection must be done in accordance with the applicable 

regulations.

•  Burners must be connected to an all-pole switch.

•  Connection must conform to the wiring diagram.

•  Use appropriately sized fuses.
