How to Open a Damper ? 3 types The damper is the small metal flap you can open and close when looking up inside your fireplace and into the chimney flue system. Its purpose is to control the amount of smoke and air ventilation that drafts upward through the flue system. You must open the damper every time you start a fire. Use the directions below to help with opening your damper, depending on the one that matches the fireplace. There's three types of dampers: Poker Damper (aka Banana Handle) Poker Damper This kind damper, Poker dampers, we commonly refer to as a banana handles. This is because of the banana shape arch in the handle. These dampers are open by lifting the handle up, pushing the damper upwards, and pinning the damper in the upward position by setting one of the notches on the handle onto the mounted ratchet on the frame of the fireplace. To close it, you simply lift the handle up again, pull the damper shut, and set the handle back into position on the ratchet. Rotary Damper Rotary Damper Number two we call a rotary damper. The dampers are operated using a metal rod that screws open and shut. Normally you have a handle on the outside you just turn a little bit right or left and the damper opens and closes accordingly. Sometimes they get a little warped rod in there and that causes a lot of problems of opening and closing. It can be a nightmare. Double Pivot Double Pivot Then the last one is what we'll call a double pivot. Its a little more complex but no harder to fix than the others. A double pivot is a lot like a poker damper, except instead of setting the handle on a separate ratchet on the frame, a ratchet with notches is already mounted to the handle AND the frame. You simply pivot the handle back and forth along the notches, allowing the handle to prop the damper open and close as you pull and set the handle into position. I can't open my damper! If you're still having problems opening your damper, its possible there may be deeper issue that needs addressing. For example, debris may have fallen from inside the chimney chase and is now sitting on top of the damper, weighing it down and preventing it from opening.
