Gas Fireplace Service questions, answered by experts

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

The damper, located just above the firebox, can open or close the chimney flue. The damper should remain closed unless there’s a fire burning in the fireplace. Closing the damper prevents energy loss through the chimney and cold air from seeping into the home during the winter. Opening the damper helps maintain airflow when there is a fire and prevents smoke and gases from venting into the house.

Some homes with wood-burning fireplaces don't have ash pits due to design choices, construction practices, or the age of the house. Many older abodes don't have them because ash pits weren't a standard feature when they were built. Additionally, in smaller homes or homes with less frequent fireplace use, builders might have opted to forgo an ash pit to reduce costs or simplify maintenance.

You can control the flame on a pellet stove by using a damper, often located on the back of the pellet stove. While the damper function varies by model, you can open the damper slightly to let in more air or close it slightly to provide less oxygen, with the ultimate goal of providing a steady flame.

Both wood-burning stoves and fireplaces can emit smoke and other combustion gases that are harmful to human health. According to the American Lung Association, wood smoke can lead to coughing and wheezing as well as long-term health impacts like increased risks for heart attacks and stroke. 

Newer models meet the modern efficiency standards set in 2020 by the Environmental Protection Agency for cleaner burning, more efficient wood stoves. Regular maintenance can also minimize smoke.
