TL;DR
The International Fuel Gas Code is the model code governing natural gas and propane systems in buildings, from the meter or tank outlet through piping, sizing, venting, combustion air, and appliance connections. Its tables size pipe by BTU load, length, and material, CSST, black iron, or copper where allowed, and its venting chapters dictate flue categories and clearances that keep carbon monoxide out of living space.
What it means
The International Fuel Gas Code is the model code governing natural gas and propane systems in buildings, from the meter or tank outlet through piping, sizing, venting, combustion air, and appliance connections. Its tables size pipe by BTU load, length, and material, CSST, black iron, or copper where allowed, and its venting chapters dictate flue categories and clearances that keep carbon monoxide out of living space. Gas fitters work to the locally adopted edition, and inspectors pressure-test new piping against its standards before the meter is set.
