ABSTRACT:
The safety valve of a fan heater is operated by a detector pipe, the outlet of which is shielded from its inlet and communicates with the warm wind circulating fan of the heater to forcibly draw burned gas into the detector pipe for stable flow therethrough. A timed delay stops operation of the fan only after the flow of gas has been shut off by the safety valve for a time sufficient to discharge combusted gas from the detector pipe.
