Abstract
A heating apparatus may include a control valve assembly. A control valve assembly can have a housing and a valve body positioned within the housing. The housing can define an inlet and first and second outlets. The control valve assembly can also include an igniter having a sensor for firing an electrode. An extension can be used to activate the sensor and to thereby activate the igniter.
Claims19
A control valve assembly for use in a heater comprising:
- a housing having an inlet, an oxygen depletion sensor (ODS) outlet, and a first burner outlet;
- a valve body positioned within the housing and configured to rotate relative to the housing so as to selectively permit fuel to flow from the inlet to one or more of the outlets, the valve body having an OFF position, a Pilot Position, a Manual Position, and an Automatic position;
- an igniter comprising a sensor, the igniter capable of repeatedly firing an electrode when the sensor is activated;
- a shaft coupled to the valve body and configured to move the valve body between the OFF, Pilot, Manual, and Automatic positions;
- an extension coupled with the shaft and extending radially outward therefrom and configured to activate the sensor and thereby to activate the igniter, wherein the extension is configured to contact the sensor and activate the igniter when the shaft is depressed regardless of whether the valve body is in any of the OFF, Pilot, Manual, and Automatic positions;
- and
- a solenoid valve configured to control fuel flow into the control valve assembly in response to an electrical input.
