1. A gas-powered heating system comprising:
a burner;
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 controller and a valve memory;
a mobile device including a mobile communication interface, a mobile processor, and a mobile memory, the mobile memory storing instructions that program the mobile processor to:
receive a valve offset from a user; and
output the valve offset of the modulating gas valve using the mobile communication interface; and
an integrated furnace controller (IFC) including a processor, a memory, and a communication interface, the IFC communicatively coupled to the modulating gas valve assembly and the mobile device, the memory storing instructions that program the processor to:
receive, using the communication interface, the valve offset output from the mobile device;
store the valve offset in the memory;
receive a call for heat; and
output one or more commands to the modulating gas valve assembly in response to the call for heat, the one or more commands causing the modulating gas valve assembly to control the modulating gas valve based on a desired gas flow rate and the valve offset.
