• Ash Pit - Space below the fireplace where the ashes are stored

• Firebox - Area in which the combustion of the fuel occurs

• Lintel - Reinforced masonry or steel angle that supports the fireplace face

Fireplace Terms

• Throat - Opening at the top of the firebox that opens into the chimney– At least 8” above the fireplace opening

– Minimum of 4” in depth

• Damper - Across the throat to prevent heat from leaving when there is no fire

Fireplace Terms

• Smoke Chamber - Acts as a funnel between firebox and chimney

• Smoke Shelf - Prevents downdrafts from the chimney into the firebox

• Chimney - Upper extension used to carry off the smoke from the fire

Fireplace Terms

• Flue - Opening inside the chimney– Required to be 1/8th or 1/10th of the opening

• Chimney Liner - Built into the chimney to provide a smooth surface to the flue wall and reduce width of the chimney wall

Energy-Efficient Fireplace

• Providing Air Supply– Outside air must be provided to the fireplace

or air from the room will leave through the chimney

– Closable vents are commonly used to allow air to enter the fireplace

– Air can also be taken from cold air returns

12

Energy-Efficient Fireplace

• Using Heated Air Efficiently– Locating the chimney inside the structure will

allow for radiant heat after the fire is out

– Increasing the size of the firebox will allow more heat

– Mechanical blowers are designed to pull air from the room and return it warmer

Energy-Efficient Fireplace

• Decreasing Chimney Heat Loss– Dampers allow heat to stay in room when

there is no fire

– Doors on the outside of the fireplace reduce the amount of air flow up the chimney

Chimney Reinforcement

• At least four vertical 1/2” bars should extend from the foundation to the top of the chimney

• Rebar is added when the vertical steel is bent for a change in the chimney

• Steel anchors connect the fireplace to framing members
