What is correct regarding fireplace chimneys?

  1. A closed control damper in a fireplace prevents heat from escaping through the chimney.

  2. A chimney cap is not required with a chimney built with bricks and mortar.

  3. Two fireplaces can share the same flue.

  4. All fireplaces require a vertical chimney that extends above the roof.

  5. Chimneys need to be cleaned every five years, regardless of usage.

  6. A chimney spark arrestor is required for all chimneys.

The correct answer is: A closed control damper in a fireplace prevents heat from escaping through the chimney.

A closed control damper in a fireplace allows the homeowner to control the amount of air that is allowed to escape through the chimney, helping to prevent heat loss and ensuring a more efficient use of the fireplace. This is especially important when the fireplace is not in use to prevent drafts and heat loss. Additionally, having a closed control damper can also help improve indoor air quality by preventing outdoor pollutants from entering the home through the chimney. Therefore, option A is correct. Regarding the other options: B. A chimney cap is actually recommended for all chimneys, regardless of their construction material, as it helps to prevent moisture, debris, and animals from entering the chimney and causing damage. C. Two fireplaces typically should not share the same flue due to the risk of backdraft or other safety hazards. D. While many fireplaces do have vertical chimneys that extend above the roof, there are also fireplace designs that utilize different types of venting systems, such as direct vents, that do not require a traditional vertical chimney extending above the roof. E. The frequency of chimney cleaning depends on usage and the type of fuel burned. It is recommended to have chimneys inspected and cleaned annually for wood-burning fireplaces and every two years for gas fireplaces. F. While a chimney spark arrestor can be beneficial in certain situations, it is not a mandatory requirement for all chimneys.
