Describe the opening in relation to the rooms
A picture of the whole wall helps an inspector place an old connection relative to a fireplace on the other side or an appliance on another floor. Record the room, approximate height and any accessible appliance records. A photograph from before the cupboard was built is useful. Avoid pulling a cover, probing the hole or using smoke to discover where it comes out.
Request a connection inventory before selecting a closure
CSIA's masonry chimney inspection procedure covers flues and their connected appliances. Ask which flue the opening communicates with, what serves that flue now, and whether any part of the assessment was inaccessible. An unused stove location is not proof of an unused passage. Keeping an appliance connected elsewhere in service may depend on how an old opening was addressed.
Tie the finish decision to a documented finding
If the proposal calls for correcting an old connection, ask who will specify the closure for that construction and how the completed condition will be recorded before cabinetry is installed. If the future plan is to add a stove, tell the inspector before choosing a finish. Reusing an old opening involves the proposed appliance and venting requirements; the size of a circular plate cannot approve that project.
