Top- Mounted, Drop-IN Liner Dampers, Chimney Pipe
The ultimate replacement for warped, worn out, or defective factory-built fireplace dampers, and for use in most pre-fab, class A, round terra cotta and stainless steel chimneys. The drop-in liner damper is easy to open and close from inside the firebox. Made of heavy stainless steel construction.
- Replaces missing, rusted or broken dampers
- Installs approx. 6″ below top allowing existing cap to be reused
- Prevents heat and air conditioning loss
- Does not induce additional resistance or turbulence and is not affected by wind
- The drop-in liner dampers can be used on:
- Class “A” solid pack
- Pre-fab fireplace
- Single-wall round
- Flexible flue liners
- Air-insulated and any pipe type chimney in size 6-16 inch round diameter.
Installation is simple, and damper is recessed approximately 6 inches below and inside the top of flue — ideal for restoration projects where an exposed damper is unwanted. The existing or new rain cover can be installed without fear of a freezing or sticking damper.
The top-mounted, drop-in liner damper is all 316-L stainless steel construction and will withstand repeated fires with no problems. It offers a spring-loaded damper that allows unlimited adjustment to open position of the damper.
Installation of drop-in liner dampers is usually about $55.00-75.00 (Raleigh, NC area only). Call Chimney Keepers at 919-772-8110 for more info.
Each damper kit comes with a 32-ft. stainless steel cable, stop spring, bracket, anchors, masonry drill bit, and cable attachment with chain handle.
$11.95 shipping on drop-in liner dampers in the U.S.! Extra shipping cost to Alaska and Hawaii of $6.95.
Other sizes are available. For more information, call (919) 772-8110 or email firstname.lastname@example.org with the size you need and your zip code.
**For proper fit, measure the inside of the flue and get a damper that matches that number. The actual damper is smaller by 1/4- 1/2″ so it slides inside the flue.
If you have a 13″ or 15″ flue, adapters are available (special order – nonrefundable). Example: Your flue is 15″. You can order a 14″ damper with an adapter that will allow it to fit inside the 15″ liner. It’s not perfect but will work most of the time. Adapters are $125.00 each. They can be made up to 20″ in diameter.
You can install one yourself with simple hand tools and an electric or battery-operated drill. Complete instructions are in every box.
Note: These dampers are specifically designed for woodburning fireplace flues and should not be used on fireplaces with gas logs. For regular rectangle or square dampers for masonry chimneys
