What does a flame safeguard system in gas appliances do?

A flame safeguard system in gas appliances is crucial for ensuring safety during operation. Its primary function is to continuously monitor the presence of a flame during the combustion process. If a flame failure occurs—due to reasons such as a draft, malfunction, or interruption in fuel supply—the flame safeguard system acts by shutting off the gas supply to prevent the release of unburned gas, which can lead to hazardous situations like explosions or fire hazards.

This system incorporates sensors that detect the flame and are connected to control mechanisms that can quickly respond in the event of an emergency. Hence, the focus of the flame safeguard system on maintaining safe operation and preventing incidents makes it an essential safety feature in devices like gas boilers, furnaces, and water heaters.
