General

Adjustment of burner

The burner is from the factory preset to an average value 

that must then be adjusted to the boiler in question.

All burner adjustments must be made in accordance with 

boiler manufacturers instructions.These must include 

the checking of lue gas temperatures, average water 

temperature and CO2 or O2 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 disappear again. Then the volume of air is 

reduced until soot occurs and increased again to reach a 

combustion free of soot.

By this procedure an optimum adjustment 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 

assembly adjustment somewhat. The CO2-content and 

consequently the air volume will then be reduced.

Condensation in chimney

A modern burner works with less excess air and often 

also with smaller nozzles than older models. This 

increases the eficiency but also the risk of condensation 

in the chimney. The risk increases if the area of the 

chimney lue is too large. The temperature of the lue 

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 lue gases 

during operation and dries them up during 

standstill)

•  Increase the oil quantity

•  Raise the lue gas temperature by removing 

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. Any boiler/burner that 

uses FAME (RME) as fuel must be serviced at least twice 

a year.

Installation instructions

General installation instructions ac company the burner 

and should be left in a prominent place adjacent to the 

burner.

Oil supply

The oil line should be dimensioned in accordance with 

the pump manufacturer´s instruction. A ilter designed for 

FAME (RME) that prevents any particles in the oil from 

reaching the burner is mounted in the burner’s suction 

pipe.  If the installation consists of several burners each 

one should have its own suction line from the tank or a 

circulation 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.  

The oil pipe and electric cable should be itted so that 

the burner can be placed on the loor for inspection of 

the combustion device.

Oil hoses must be of a quality designed for FAME (RME).
