The assessment will be conducted before the connections are made between the exterior and interior portions of the system.

• A. True
• B. Not specified
• C. N/A
• D. False

Answer: (D)

Testing the system after completing the connections between exterior and interior portions is essential. The purpose of the assessment is to verify that all joints, fittings, and boundaries between the exterior piping and the interior appliances are leak-free once the system is assembled. If you tested before making those connections, you wouldn’t reveal leaks at the critical interface where exterior supply meets interior components, which is exactly where leaks could cause gas to escape into occupied spaces. By performing the leak test after everything is connected, you confirm the whole system is safe to operate.

That’s why the statement is false—the proper sequence is to conduct the assessment after the connections are made, not before.
