How much gas pipe has to stub out of the floor not including threads

• A. 3"
• B. 2"
• C. 1"
• D. 4"

Answer: (B)

In gas pipe installations, the stub-out length from the finished floor is chosen to give enough clearance for a connector or flex line while keeping the pipe accessible and protected. The standard stub-out length, not including threads, is two inches. This provides enough room to connect the appliance supply without crowding the base of the appliance or requiring awkward angles, while still keeping the end of the pipe above the floor surface for protection and ease of future maintenance. If the stub were shorter, you’d risk insufficient room to engage the connector properly or misalignment during installation. If it were longer, it could create clearance issues with the appliance or cabinetry and be unnecessarily exposed.
