TWO-STAGE GAS BURNERS: TROUBLE-SHOOTING GUIDE

POSSIBLE CAUSE

1)  Disturbance to ionization current from 

ignition transformer.

2)   Flame sensor (ionization probe) ineffi

-

cient.

3)  Flame sensor (ionization probe) position 

incorrect.

4)  Ionization  probe  or  relative  earth  ca-

ble.

5)  Electrical  connection  cut-off  by  flame 

sensor.

6)  Inefficient  draught  or  fumes  passage 

blocked.

7)  Flame disk or combustion heads dirty 

or worn.

8)  Equipment fault.
9)   No ionization. 

1)  Fault in ignition circuit.

2)  Ignition transformer cable discharges to 

earth.

3)  Ignition  transformer  cable  discon-

nected.

4)  Ignition transformer faulty.
5)  The  distance  between  electrode  and 

earth is incorrect.

6)  Isolator  dirty,  so  electrode  discharges 

to earth. 

1)  air/gas ratio incorrect.

2)  Gas pipe has not been properly bled of 

air (in the case of first ignition).

3)  The  gas  pressure  is  insufficient  or 

excessive.

4)  Air  flow  between  disk  and  head  too 

narrow. 

SOLUTION

1)  Invert the ignition transformer power 

supply (230V side) and check using 

an analog micro-ammeter.

2)  Replace flame sensor.

3)  Correct the position of the flame sen

-

sor, and then check its efficiency by 

inserting the analog micro-ammeter.

4)  Check visually and using the instru

-

ment.

5)  Restore the connection.

6)  Ensure that the boiler fumes passage 

and chimney connection are free.

7)  Visually check and replace, if neces

-

sary.

8)  Replace.
9)  If the “earth” of the apparatus is not 

efficient, do not check the ionization 
current.  Check  the  efficiency  of  the 

“earth”  at  the  terminal  concerned 
of  the  apparatus  and  at  the  “earth” 

connection of the electric system.

1)  Check the ignition transformer power 

supply (230V) and high voltage circuit 
(electrode to earth or isolator broken 
under locking terminal).

2)  Replace.

3)  Connect.

4)  Replace.
5)  Position at the correct distance.

6)  Clean or replace isolator and electro-

de.

 

1)  Correct the air/gas ratio (there is pro-

bably too much air or very little gas).

2)  Bleed the gas pipe again, taking great 

care.

3)  Check  the  maximum  gas  pressure 

value 

at the time of ignition

 (use a 

water pressure gauge, if possible).

4)  Adjust the disk/head opening. 

DETAILS OF PROBLEM

The apparatus goes into “lock-out” with 

the flame (red light on).

flows out, but there is no flame (red light 
on).Fault restricted to ignition circuit.
