Patent ID: 7654820

Claim:
A control valve assembly for gas heaters and gas fireplace devices, the assembly comprising: a housing defining: an inlet for accepting fuel from a fuel source; a first outlet for delivering fuel to an oxygen depletion sensor; and a second outlet for delivering fuel to a burner; a valve body configured to selectively provide fluid communication between the inlet and one or more of the first outlet and the second outlet; an actuator configured to move the valve body relative to the housing, the actuator configured to transition between a resting state and a displaced state; an igniter comprising a sensor, the igniter electrically coupled with an electrode and configured to repeatedly activate the electrode when the sensor senses that the actuator is in the displaced state; and a first shutoff valve electrically coupled with the oxygen depletion sensor and configured to operate in response to an electrical quantity communicated by the oxygen depletion sensor; wherein the housing further defines a first passageway and a second passageway through the valve body and to the second outlet, and in a first mode the valve body will permit flow through the first passageway from the valve body to the second outlet and prevent flow through the second passageway from the valve body to the second outlet and in a second mode, the valve body will permit flow through the second passageway from the valve body to the second outlet and prevent flow through the first passageway from the valve body to the second outlet.
