GASEOUS FUEL BURNER SYSTEM

摘要

A gaseous fuel burner system wherein a single burner is designed to operate at dual rates in accordance with the fuel flow supplied by a combination control device which is operated thermostatically and which includes the features of a manual on-off valving mechanism and a burner flame responsive safety valving mechanism. A single conduit between the control device and the burner supplies the fuel flow at both rates of flow to the burner that provides two flame patterns with each flame pattern impinging on the flame responsive element of the safety valving mechanism.
