Abstract
A method for calibrating a position of a control valve within a gas valve assembly for controlling fuel flow to a combustion appliance. The method may include moving the control valve to a second end stop, moving the control valve from the second end stop to a first end stop while counting a number of steps traveled by a stepper motor driving the control valve, and comparing the counted number of steps traveled from the second end stop to the first end stop to a reference value stored in a memory of the controller. If the counted number of steps does not match the reference value, the gas valve assembly may be placed in a lockout mode.
