The Leisure A028173 flame supervision device (FSD) plays a crucial role in the safety of your gas appliance. Should a flame extinguish accidentally, the FSD will ensure your gas supply is cut automatically.
The signs your FSD has stopped working is the presence of a gas smell or leak with no flame. Left unfixed, this could be extremely dangerous and could cause injury.
If you're not confident you are able to fit this part, we suggest you use a Gas Safe registered engineer to ensure it is fit correctly.
