The approved ductwork specification requires all joints to be sealed. Inspection finds an unsealed joint. What action meets that stated requirement?
- Seal the joint using the specified approved method.
- BLeave it open if the gap is under 1/4 inch.
- CLeave it open if the gap is under 1/2 inch.
- DIgnore the joint if the fan still runs.
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why A is correct
An unsealed joint does not meet the stated sealing specification and must be corrected using the specified method. This does not assert that every installed duct system has literally zero leakage or replace applicable leakage testing.
