Question: 1 / 400

The fireplace throat or damper must be located above what height relative to the top of the fireplace opening?

6 inches

8 inches

The correct height for the fireplace throat or damper is indeed 8 inches above the top of the fireplace opening. This specification is essential for ensuring proper airflow and smoke management while minimizing the risk of smoke entering the living space. When the damper is set at this height, it helps to create a more effective draft, which is crucial for efficient burning and preventing smoke from backing up into the room.

Setting the damper too low can lead to improper combustion, inefficient burning, and increased creosote build-up, which raises the risk of chimney fires. Thus, the 8-inch guideline serves as a practical measure that balances functionality with safety in fireplace design and operation. This understanding is vital for anyone involved in chimney construction, maintenance, or inspection, underpinning the broader goals of safety and performance in chimney systems.
