This is an energy saving damper that can eliminate as much as 90% of the air loss of a traditional damper. It is mounted on top of a flue tile and seals tightly with silicone rubber so that you save both energy and money. A leverage of 143 lbs. opens the damper easily. The kit includes the hardware, 32' cable, silicone sealant and full instructions. Top-sealing dampers are not recommended for use with gas logs because a failure in opening could cause carbon monoxide to build up inside the house.

How do you put a chimney cleaning brush down the chimney to clean the inside of the chimney walls?
How do you put a chimney cleaning brush down the chimney to clean the inside of the chimney walls?

First, we always recommend having a professional chimney sweep perform such cleaning. Typically, they would clean from the top-down, pushing the brush down through the flue to the smoke chamber.

Had a Draft...Nevermore!

My parents house was built in the early 60's and while getting work done through out the house, we found that the original damper was dilapidated and was not operable anymore. Our searches on the Internet led us to eFireplaceStore and I ordered 2 each to close off the double flues. 4 days later they arrived and my contractor installed them! We are very well satisfied with the way they operate. They're easy to install and they look very good from the curb. Thanks for the timely order and well made material!!!

Every chimney should have one!

I have a wood stove in my 1956 fireplace, with black pipe going up through the existing top-of-the-fireplace cast-iron damper/flue. So, the damper is permanently open and as such, even though I've sealed around the black pipe, I get drafts coming down through the stove (when it's not running). At times, I would come home and the house would smell like chimney/fire even though I hadn't used the wood stove for days. Similarly, with my well-insulated house, when I ran the strong exhaust fan in my kitchen, ice-cold, smelly air would be drawn down the chimney and through the dormant wood stove. Not good. This damper was PERFECT for this situation and frankly should replace every one of the old cast-iron dampers in every fireplace in America since they don't do much to seal off what's basically a wide open HOLE to the great outdoors. It was easy to install - the hardest part is getting on the roof, seriously. You drop the cable down the chimney, check that it swings right when it's sitting on top, and then smear the included goop on top of the clay liner and plop the damper on top. Climb back down, wait for the goop to set and put in a couple of screws for the included bracket to hold the cable out of the way. I can't recommend this highly enough. Seriously; every chimney without one is just a hugely inefficient part of any home.

Perfect

Installation very simple. Forms a tight seal. We're very pleased.

Pros

Easy installation Stops all airflow through the chimney Blocks ambient noise Prevents cold air escaping

Cons

When the damper is opened after being closed for a few days, small pieces of dirt and (perhaps) leaf debris float down into the fireplace.

Appropriate

Good workmanship. Some better guidance on installation would be helpful. As it was, we had to figure out the placement, the way to get the rivets into the chimney, the right sealant.

Pros

Craftsmanship good

Cons
