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.

1. 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; anda solenoid valve configured to control fuel flow into the control valve assembly in response to an electrical input. 2. The control valve assembly of claim 1, wherein the sensor comprises a button sensitive to pressure actuation configured such that contact of the extension with the sensor results in multiple firings of the electrode. 3. The control valve assembly of claim 1, wherein the sensor comprises a magnetometer. 4. The control valve assembly of claim 1, wherein the extension is substantially disk-shaped. 5. The control valve assembly of claim 4, wherein the extension has a radius larger than the distance between an axial center of the shaft and the sensor of the igniter. 6. The control valve assembly of claim 5, further comprising a selector knob coupled with the shaft. 7. The control valve assembly of claim 6, wherein the extension is configured to contact the sensor and activate the igniter when the knob is depressed, regardless of the rotational orientation of the knob. 8. The control valve assembly of claim 6, further comprising a biasing member configured to bias the shaft and knob to an upward position away from the housing. 9. The control valve assembly of claim 1, further comprising a protrusion on the shaft and a plurality of recesses on the housing, the protrusion configured to fit within one of our recesses on the housing after the shaft and valve body have been rotated, each recess corresponding with one of the OFF position, Pilot Position, Manual Position, and Automatic position of the valve body. 10. The control valve assembly of claim 9, further comprising a stop configured to prevent rotation of the protrusion past the stop. 11. The control valve assembly of claim 1, further comprising the electrode, the electrode being electrically coupled to the igniter. 12. The control valve assembly of claim 11, wherein the electrode comprises a piezoelectric material. 13. The control valve assembly of claim 1, further comprising a thermocouple wherein the solenoid valve is coupled to the thermocouple. 14. The control valve assembly of claim 1, further comprising a second burner outlet. 15. The control valve assembly of claim 14, further comprising a plug positioned in one of the burner outlets. 16. The control valve assembly of claim 14, wherein the second burner outlet is positioned on the housing 90 degrees off set from the first burner outlet. 17. The control valve assembly of claim 1, further comprising a temperature regulator having a thermostat configured for regulating a fuel flow through the valve assembly based on a temperature outside of a heater. 18. The control valve assembly of claim 17, wherein the temperature regulator further comprises a battery. 19. The control valve assembly of claim 17, wherein the temperature regulator further comprises a power interface for coupling with a power source.
