Ignition lance:

 p

gas

 = 30 – 50 mbar,

 p

air

 = 30 – 50 mbar.

 

Check flame stability and ionization current.

 

The gas and air pressure of the ignition lance 

must be higher than the gas and air pressure of 
the main burner.

Commissioning

Igniting and adjusting the burner

 WARNING

Ensure adequate ventilation of the furnace chamber 
before each burner start!

 

The burner housing will become hot during op-

eration with preheated combustion air. Provide 
protection against accidental contact as required.

  • 

  All valves of the installation must be checked for 

tightness before ignition.

Setting the low-fire rate:

  • 

 Set the valves to ignition position.

  • 

 Limit the maximum gas volume.

 

Should an adjustable gas restrictor be installed 
upstream of the burner, open the restrictor by 
approx. a quarter.

  • 

 Open the gas supply.

  • 

 Ignite the burner.

 

The safety time of the automatic burner control 

unit starts to elapse.

  • 

  If no flame forms, check and adjust the gas and 

air pressures of the start gas adjustment.

  • 

 In the case of operation with bypass (e.g. when 

using an air/gas ratio control): check the bypass 
nozzle and adjust if required.

  • 

 In the case of operation without bypass (e.g. 

when using an air/gas ratio control without by-
pass):

 

increase the low-fire rate setting.

  • 

  Check the basic setting or bypass of the air con-

trol valve.

  • 

  Check the position of the restrictor in the air line.

  • 

 Check the fan.

  • 

 Reset the automatic burner control unit and re-

ignite the burner.

 

The burner ignites and proceeds to normal op-

eration.

  • 

 Check flame stability and ionization current at 

low fire. Switch-off threshold – see automatic 
burner control unit operating instructions.

  • 

 Monitor flame formation.

  • 

 Adjust the low-fire rate settings if required.

  • 

 If no flame forms – see page 11 (Assistance 

in the event of malfunction).
