7  Servicing 

 

 

 

A suitably qualified and competent engineer such as a Gas safe/ACS Registered Installer must 
carry out all the maintenance operations discussed in this section at least once a year.  
In the case of seasonal servicing, it is recommended that the service operations be carried out at 
the end of each heating season.  
In the case of continuous operation, the service operations should be carried out every six months.  

 

 

 

Before removing the burner from the appliance: 

 

1.  Ensure you have a replacement burner mounting gasket for re-fitting the burner afterwards. 
2.  Prepare an appropriately sized and relatively clean and tidy work area to conduct the 

maintenance operation.

 

 

7.1

 

Service Inspection 

 

Isolate and disconnect both the gas and electrical supplies from the burner. 
Supporting the weight of the burner, carefully remove the fixings securing it to the appliance and 
withdraw it from the chamber.  

 
7.1.1 

The condition of the burner head 

some discolouration of the burner material is normal, but the material should not be cracked or 
open. Under no circumstances should any of the perforated holes in the burner tube beneath the 
material be visible. Inspect the flange of the burner for any signs of cracking or severe overheating, 
which may indicate leakage.  
Any serious burner head defect would constitute an ‘

Immediate Danger’

 and the burner system 

SHOULD NOT

 be put back into operation until adequately repaired. 

 

7.1.2 

The condition of the electrodes 

Check the ceramics are not cracked or damaged and check that the wire head is still approximately 
4mm gap between the Ignition electrode and the burner surface. 

 

 

DO NOT 

clean the electrodes and if adjustment is required always try and adjust the wires near to 

the ceramic

 

and preferably using a blowtorch to pre-heat the wire.  

 
7.1.3 

The condition of the electrical circuits 

Check the condition and integrity of the internal burner wiring harness and plugs, ensuring that all 
connections are secure. Check that both the ignition and detection leads are in good condition.
