The electro thermal link is designed to be installed in a position where it is possible for a fire to occur. This location will usually be above a burner of an air heater or boiler. If a fire occurs, this will melt the fusible metal link and interrupt the electric supply. The thermal link consists of a purpose built steel casing with a perforated cover containing a temperature sensitive fuse. The unit should be mounted so that the perforated cover faces downward. It is important that the ventilation holes in the sides are not obstructed.
