Question: 1 / 400

What is the maximum allowable length for a gas appliance connector in residential applications?

4 feet

6 feet

The maximum allowable length for a gas appliance connector in residential applications is established to ensure safe and effective operation of gas appliances while minimizing the risk of leaks or other hazards. The correct answer, which is 6 feet, reflects the industry standards set by safety codes such as the National Fuel Gas Code in Canada.

This 6-foot limit ensures that the connector is long enough to allow for some flexibility in positioning gas appliances but short enough to maintain tight connections and prevent excess movement that could loosen fittings or cause wear. Proper connector length is crucial because longer connectors can introduce additional risk factors like kinking or damage, which may lead to gas leaks.

In many installations, this regulation helps to ensure that gas appliances operate safely and efficiently, maintaining both user safety and appliance function.
