Fireplace System 101: Parts of Your Chimney and Heating System

• Damper: Located above the fireplace, the damper keeps warmth in when you don’t have a fire burning and is a panel that either tilts or slides into place to block the way between the fireplace and chimney.
• Smoke chamber: The area directly above your fireplace, the smoke chamber is an area where smoke collects from the fire before proceeding up the chimney and out of your home or business.
• Flue: The flue is the inside of the chimney. It can be finished using flue tiles, which are hollow fired clay tubes that have a smooth interior finish to help prevent creosote or debris from building up.
• Lining: In cases where the flue is damaged or is too large for a new appliance, a lining may be inserted to allow for better efficiency, superior draft, or other reasons, helping improve safety and efficiency.
• Masonry: The bricks on the outside of many chimneys and the mortar that holds them together keep moisture from entering the interior of the chimney structure, where it can cause severe damage.
• Crown: The wider part at the top of the chimney, the crown is often made of cement. Its job is to keep moisture from dripping down the sides of the masonry, preventing wear and tear on the mortar joints.
• Cap: At the very peak of the chimney is a small roof, typically of metal, and in most cases a screen that encloses the top of your chimney. This allows smoke and vapor to exit while keeping rain, animals, and debris out.
