What is the maximum length allowed for a flexible connector?

The maximum length allowed for a flexible connector in gas systems is critical for ensuring safety and proper function. The correct answer indicates that a flexible connector can be up to 2 feet long. This limitation is established because flexible connectors are intended to accommodate movement, vibration, or thermal expansion between components, such as appliances and gas piping.

Allowing a longer flexible connector could introduce additional risk factors, such as increased friction, pressure drops in the gas line, or potential damage from movement. By restricting the length to a maximum of 2 feet, regulations help maintain the integrity of the gas system while still allowing the necessary flexibility for installation and operation.

Other lengths provided are not permissible, as they exceed the limits set by safety codes which govern gas installation practices. Adhering to these standards is essential for preventing gas leaks and ensuring the safe operation of gas appliances.
