Service questions
Details worth understanding.
Final specifications depend on the inspected conditions, appliance listing, selected manufacturer and applicable local requirements.
Can the throat damper remain in place?+
Sometimes, depending on its condition and the selected system. It must not obstruct operation or create confusion during fireplace use.
Does a top damper replace every chimney cap?+
It protects its flue opening, but multi-flue crowns or other vent terminations may still need separate protection.
