Journeyman Plumber ExamGas PipingEasy
A plumber is installing a gas clothes dryer and a gas range in a residential kitchen. Both appliances will be connected using flexible appliance connectors. What is the maximum allowable length for a flexible gas appliance connector, according to most plumbing codes?
- A6 feet
- B4 feet
- C3 feet
- D2 feet
Show answer & explanationAnswer & explanation
Correct answer: A. 6 feet
Most plumbing and mechanical codes limit the length of flexible gas appliance connectors to a maximum of 6 feet. This restriction is in place to minimize the risk of damage, kinking, or accidental disconnection, while still allowing for appliance mobility.
Why the other options are wrong
- B. This length is also common but not the maximum permitted by code.
- C. While a common length for some connections, it is not the maximum allowable.
- D. This length is too short and generally impractical for most appliance installations.
Flexible Gas Connector Length
Flexible gas appliance connectors have a maximum allowable length specified by code to ensure safety, prevent damage, and maintain proper gas flow to the appliance.
- Used for connecting movable appliances.
- Must be approved for gas service.
- Length limit prevents kinking and damage.
Memory trick: Flexibility is good, but 'Six' feet is the 'Max' for gas connections.
