What is the required distance within which a union must be installed for gas appliances connected by rigid metallic piping?

2 feet
3 feet
4 feet
6 feet

The correct answer is: 3 feet

The correct answer of three feet is based on safety regulations that govern the installation of gas appliances. When connecting gas appliances using rigid metallic piping, a union must be installed within three feet of the appliance. This requirement is crucial because it allows for easier maintenance and disconnection of the appliance without needing to disassemble extensive lengths of piping. The three-foot distance serves as a standard to ensure that the union is accessible, facilitating repairs or replacements without compromising the integrity of the gas line. This practice helps maintain safety standards and ensures that gas appliances can be serviced effectively while minimizing the risk of gas leaks or issues that could arise from inadequate accessibility to the piping.
