Abstract
In certain embodiments, a control valve assembly for gas heaters and gas fireplace devices includes a housing. The housing can define 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. The assembly can include a valve body configured to selectively provide fluid communication between the inlet and one or more of the first outlet and the second outlet, and can include an actuator configured to move the valve body relative to the housing. The actuator can be configured to transition between a resting state and a displaced state. The assembly can include an igniter that includes 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. The assembly can include a 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.
