What is a potential consequence of improper sizing of gas piping?

Improper sizing of gas piping can lead to insufficient gas supply to appliances, which is a significant concern in gas fitting. Gas piping must be sized correctly to ensure that there is adequate flow and pressure to appliances when they are in operation. If the piping is too small, it can restrict the flow of gas, leading to appliances receiving less gas than needed for optimal performance.

This insufficient gas supply may cause appliances to operate inefficiently or not at all, resulting in issues such as incomplete combustion, poor heating performance, or even failure to ignite. In contrast to properly sized piping, which allows for efficient gas distribution and appliance performance, improperly sized piping creates a range of operational problems and could lead to hazardous situations.
