Abstract

A control device for burner apparatus having a differential pressure operated diaphragm valve controlled by an internal bleed system which is subject to pressure regulation and to on-off control by sequentially operated bypass and bleed valves which are actuated by a heat motor operator. Initial actuation of the heat motor operator opens the bleed valve to provide a step input at a reduced rate under pressure regulation to the main burner for assuring good ignition without "roll-out." Subsequent control of the bypass valve enables flow modulation, and full input is delayed until the bypass valve is fully closed.
