ABSTRACT:
A thermostat assembly for a gas fired oven including an integral control valve having a rotatable tapered valve member with axially spaced valving grooves, separately valving fuel gas flow to the standing pilot and main burner lines from separate inlet ports in a tapered bore in the valve block. In the "OFF" and "PILOT" valve positions, fuel gas is permitted to flow only to the pilot burner line. In the range of "ON" position, fuel gas is permitted to flow to both the main burner and pilot lines. Rotation of valve to any of the "ON" positions varies the setting of a thermostat which responds to ambient temperature to substantially reduce main burner flow when a desired ambient temperature has been reached.
