Abstract
A method of controlling a gas powered water heater includes attempting to pick a main gas valve of the main burner using a first pick method. The first pick method includes closing a switch of a valve pick system to couple a capacitor of the valve pick system to the main gas valve for a first length of time to discharge energy stored in the capacitor to the main gas valve, and opening the switch of the valve pick system after the energy stored in the capacitor is discharged to the main gas valve. The controller determines if the main gas valve is open after using the first pick method. When the controller determines the main gas valve is not open, the controller attempts to pick the main gas valve using a second pick method different than the first pick method.
