HEATING APPARATUS AND METHOD |
摘要 |
A purging system for a heating apparatus according to the present invention includes a pair of three-way valves interposed serially between a burner head and a supply of combustible fluid. Each valve is connected to a switch for switching between two modes of conduction. One of the valves is controlled by a remote switch so that the burner may be flushed manually by an operator. The other switch senses whether the heating apparatus is operating and flushes the burner automatically when the apparatus is inoperative. |
