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

Warning signs to look out for
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:
- Difficulty in starting: this can mean that there may be a blockage preventing the pilot from lighting properly. This should be inspected by a certified gasfitter
- 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.
This problem can present in several ways:
- The noise made when combusted and ignited
- Yellow flame
- Unstable flame
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.
If you can smell gas, gas is leaking from the pipes or the appliance itself due to faulty connections. In this instance, it is safest to contact your local gasfitter to investigate and rectify the issue.
