摘要
A radiant gas heater includes a first ceramic plaque burner and an adjacent and larger second plaque burner. A valve spindle is movable to establish in series "Low," "Medium" and "High" heat positions by first supplying gas in the vicinity of the first burner, then supplying gas in the vicinity of the second burner while momentarily maintaining the flow of gas to the first burner, next discontinuing the flow of gas to the first burner and finally by reestablishing the flow of gas to the first burner while maintaining the flow of gas to the second burner.
