Abstract: A coaxial gas valve assembly includes a gas inlet, a gas outlet, a valve tube, and a shaft member. A main valve is movable between a closed position and an open position (broadly, openable and closable). A main spring is positioned to resiliently bias the main valve in its closed position. A redundant valve is movable between a closed position and an open position (broadly, openable and closable). A redundant spring is positioned to resiliently bias the redundant valve in its closed position. A solenoid coil is positioned to electromagnetically move the shaft member within the valve tube. A balance diaphragm is connected to the valve tube. A gas path through at least the valve tube allows gas flow from a first side of the balance diaphragm to a second side of the balance diaphragm to reduce a pressure difference between the first and second sides of the balance diaphragm.

Abstract: An automatic pilot lighting system for unattended automatic lighting of a standing pilot may include a powered (e.g., battery powered, etc.) circuit. The powered circuit may include an analog timer circuit including a timer switch. A spark ignitor may be coupled with the timer switch. A temperature knob pilot momentary switch may be coupled with the timer switch. An ON/OFF switch may be coupled with the temperature knob pilot momentary switch and the timer switch. The ON/OFF switch may be configured to be operable for selectively disabling and enabling a power source. The analog timer circuit may be configured to be selectively activatable for applying voltage from the power source via the ON/OFF switch for pilot hold voltage and spark ignition for an amount of time sufficient to allow for unattended automatic lighting of the standing pilot and sufficient voltage generation to support standalone operation.

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.

Abstract: A control system for a gas powered appliance includes a power source to provide electrical power to control at least one electrically actuated gas valve, a valve control system to selectively couple electrical power from the power source to the electrically actuated gas valve, and a controller. The valve control system includes a first switch and a second switch. The first switch and the second switch are electrically connected in series between the power source and the electrically actuated gas valve. The controller is operatively connected to the first switch and the second switch and configured to control the first switch and the second switch to selectively couple power from the power source to the electrically actuated gas valve.

Abstract: A safety system for use with a thermoelectric generator is described. The safety system includes a safety switch operatively connected to the thermoelectric generator output. The safety switch has a first state in which the thermoelectric generator can provide a first voltage to a load, and a second state in which the thermoelectric generator cannot output the first voltage to the load and in which the thermoelectric generator can output a second voltage to the load. The second voltage is a non-zero voltage having a magnitude less than the first voltage.
