Each of the burners will have a burner cap, a lighting plug, a thermocouple and a triple-flame cap.

  • Wash the flame caps and burner caps often with hot water and detergent
  • The hob pan stands can be washed in a dishwasher
  • For stubborn deposits, use an ordinary non-abrasive detergent or specific commercial products. Do not use scouring pads, steel wool or acids to clean your hob

Looking out for any warning signs that your gas appliance is not working optimally means you can operate it safely within the specifications. Some signs to look out for:

  • Burning yellow flames: this means there is too much oxygen during combustion, which means the hob may be getting blocked.

Problems and Corrective Measures


A problem with the ignition may present as a badly ignited flame or no ignition at all. There are many causes of this and investigation and repair by a certified gasfitter is required. Probable causes range from badly assembled parts, blocked or clogged parts and broken or faulty parts.

Ignition with incomplete combustion 

This issue presents if the fire goes out as soon as you release the control knob, if the flames go out unexpectedly or if the fire turns off whilst in use. This can indicate issues with the flame supervision device or draughts near the appliance. In this case, it is best to call in a certified gasfitter to investigate the issue and repair or replace the parts. 

Incomplete combustion

This problem can present in several ways:

  • The noise made when combusted and ignited
  • Yellow flame
  • Unstable flame
  • Lifting
  • Backburn

Most of these issues are related to gas supply and the correct type of gas for your assembly type. Calling in a gasfitter to check whether you have the right type of gas should be your first port of call.
