Thermal fuse

Thermal fuse

All gas hobs are equipped with a safety thermal fuse, which prevents gas leakage in the event of the flame going out accidentally. The burners are equipped with rotary selectors with a safety system, which automatically stops the gas supply in the event of the flame going out accidentally, thus preventing the risk of gas leakage into the room.
The safety thermal fuse is a metal roller located in close proximity to each burner, in case, that the flame goes out unexpectedly, the gas supply will be shut off in less than 30 seconds.
