1. A gas-powered heating system comprising:
a burner;
a peripheral component programmed to receive a valve offset; and
a modulating gas valve assembly connected between a gas source and the burner, the gas valve assembly including:
a modulating gas valve to variably control a flow of gas through the gas valve assembly; and
a control circuit including a valve memory storing a calibration table for the modulating gas valve, and a valve processor communicatively coupled to the peripheral component, the calibration table including a plurality of control settings for the modulating gas valve, each control setting being associated with a different gas flow rate, the valve processor programmed to:
receive a command to open the gas valve; and
control the gas valve to a target control setting in the calibration table adjusted in accordance with the valve offset.
