Flue – Empty space inside your chimney that allows combustion gases to vent.
Flue lining – Stainless steel lining system for venting.

Smoke Chamber – To gently compress the byproducts of combustion into a smaller space (the chimney) without causing backdraft. The use of sloping walls, in conjunction design and maintenance.
Damper – Lever or pulley activated doors within your chimney that can be closed to prevent energy loss when your fireplace isn’t being used.
Smoke Shelf – Located right behind the damper to catch falling debris and rain water and to help with the transition of large volumes of smoke into the small chimney.
