GENERAL INSTRUCTIONS

General rules

The installation of an oil burner should 

be carried out in accordance with local 

regulations. The installer of the burner 

must therefore be aware of all regula-

tions relating to oil and combustion.

Only oil suitable for the burner should 

be used and then in combination with 

a suitable oil fi lter before the oil pump 

of the burner.

If the burner is replacing an existing 

burner make sure that the oil fi lter is 

replaced or cleaned. The installation 

must only be undertaken by expe-

rienced personnel. Care should be 

taken by the installer to ensure that no 

electrical cables or fuel/gas pipes are 

trapped or damaged during installation 

or service/maintenance.

Installation instructions

General installation instructions ac-

company the burner and should be 

left in a prominent place adjacent to 

the burner.

Adjustment of burner

The burner is from the factory pre-set 

to an average value that must then 

be adjusted to the boiler in question. 

All burner adjustments must be 

made in accordance with the boiler 

manufacturer´s instructions.These 

must include the checking of fl ue gas 

temperatures, average water tem-

perature and CO

2

 or O

2

 concentration. 

To adjust the combustion device, start 

by increasing the air volume and the 

nozzle assembly somewhat.When the 

burner starts it is  burning with excess 

air and smoke number 0. Reduce the 

nozzle assembly adjustment until 

soot occurs, and then increase the 

adjustment to make the soot disap-

pear again. Then the volume of air 

is reduced until soot occurs and in-

creased again to reach a combustion 

free of soot.

By this procedure an optimum adjust-

ment is obtained. If larger nozzles are 

used the preadjustment of both the 

air volume and the nozzle assembly 

must be increased.

A whistling sound may be heard 

which can be eliminated or reduced 

as follows: Increase the nozzle as-

sembly adjustment somewhat. The 

CO

2

-content and consequently the air 

volume will then be reduced.

Oil supply

The oil line should be dimensioned 

in accordance with the pump 

manufacturer´s instruction. In the 

suction line to the burner a fi lter should 

be mounted to prevent any particles 

in the oil from reaching the burner. 

If the installation consists of several 

burners each one should have its own 

suction line from the tank or a circula-

tion system should be used. 

The temperature in the oil line should 

be kept as constant as possible. Avoid 

exposing the line to excessive cold 

which may cause blockages of paraffi n 

deposits.

The oil pipe and electric cable should 

be  fi tted  so  that  the  burner  can  be 

placed on the fl oor for inspection of 

the combustion device.

Condensation in chimney

A modern burner works with less ex-

cess air and often also with smaller 

nozzles than older models. This 

increases the effi ciency but also the 

risk of condensation in the chimney. 

The risk increases if the area of the 

chimney fl ue is too large. The tempera-

ture of the fl ue gases should exceed 

60°C measured 0,5 metres from the 

chimney top.

Measures to raise the temperature:

Insulate the chimney in cold attics

Install a tube in the chimney

Install a draught regulator (dilutes the 

fl ue gases during operation and dries 

them up during standstill)

Increase the oil quantity

Raise the fl ue gas temperature by re-

moving turbulators, if any, in the boiler.

Pump adjustment

See separate description.

Maintenance

The boiler/burner should be examined 

regularly for any signs of malfunction 

or oil leakage.
