Abstract
A valve unit includes a valve member that moves relative to a valve seat in response to a magnetic field generated by a coil. An input signal to the coil controls the extent of movement of the valve member relative to the valve seat, to control a gas flow rate therethrough. The gas valve unit also includes a setting adjustment device that provides a setting adjustment input utilized for calibrating or adjusting at least one gas flow rate. A valve controller is configured to receive an activation signal and to responsively send an input signal to the coil to move the valve member and establish at least one desired gas flow rate corresponding to the activation signal, wherein the valve controller is configured to adjust the input signal to the coil based on the setting adjustment input, to thereby enable field adjustment of at least one gas flow rate.
