How flame rectification works
WebFor gas appliances, a flame supervision device ( FSD) – alternative name: flame failure device ( FFD) – is a general term for any device designed to stop flammable gas going to the burner of a gas appliance if the flame is extinguished. This is to prevent a dangerous buildup of gas within the appliance, its chimney or the room. [1]
