As not all the effects caused by the equipment 

are known, setting the burner using the pressure 
values is only approximate. It is possible to set 
the burner precisely by measuring the flow rates 
or flue gas.

Restrictors

 

The air volume required for the low-fire rate at a 

given air pressure is determined by the ignition 
position of a butterfly valve, a bypass hole in the 
air valve or an external bypass with restrictor.

Hot-air compensation

 must be in-

creased in hot-air operating mode (lambda =

Low fire:

 

The burner must only be ignited at low fire (be-

tween 10 and 30% of the rated capacity Q

max

 – 

see type label).

  • 

 Reduce the air supply on the air control valve 

and set the desired low-fire rate, e.g. using a 
limit switch or mechanical stop.

 

On air control valves with bypass, the bypass 
orifice should be determined on the basis of the 
required flow rate and the existing supply pres-
sure if required.

High fire:

  • 

  Set the required air pressure p

air

 on the air restric-

tor upstream of the burner.

  • 

 When using air restricting orifices: check the air 

pressure p
