Lock Top Damper Cable

Q: Jason, I have a 113-year-old house with 6 fireplaces … they were originally coal-burning units .. they all have the lymance lock top damper on the top of the chimney … will the Chimney Balloon work with that configuration? – GB

A: GB, WOW 6 fireplaces! that has to be some kind of record! It is very wise that you have a chimney top damper on these chimneys, however the chimney top damper still allows the warm air of your home to rise up into the chimney and cool in the chimney and sink back down. You may notice a slow cool release of air from your fireplaces. That cool air is likely not outside air, but just cooled inside air sinking back down again. We have had customers with chimney top dampers that have used the Chimney Balloon on the bottom of their chimney in addition to their top damper and it has made a difference. With 6 chimneys the difference would be significant.

Q: Jason, thanks for the response … one of my concerns is if the damper cable will interfere with the Chimney Balloon sealing property. And if I am using a Chimney Balloon and a lock top damper … could I just use a Chimney Balloon, and not bother with the lock top damper? – GB

A: GB, Recently a homeowner in Detroit asked me the same question you are asking when he ordered 3 Chimney Balloons for his home. He had Lock-top dampers just like you, on all three chimneys as well. After he installed the Chimney Balloon he reported that it sealed just fine despite the chain or cable. The Chimney Balloon simply presses the chain or cable against the flue wall if the cable is relaxed. Or if the cable or chain is tight, the Chimney Balloon will envelop and expand around the cable causing no noticeable leak or draft.

Lock top damper cable

Q:  Jason – I currently have a chimney cap installed with a stainless steel wire and handle on the end which is mounted to the side of the firebox on the face of the brick. The metal damper is removed and this wire extends up through the smoke chamber and up the flue to the cap. Can I still install a Chimney Balloon? – JR

A: JR – This type of damper is often referred to as a Chimney Top Damper. Many are made by a company by the name of Lymance or Seal tight.

 Yes, you can use a Chimney Balloon in this configuration. As the Chimney Balloon inflates it will envelop the wire (as in the picture above). You will find the double draft protection of the chimney top damper and the Chimney Balloon together to be very effective.

Clean Your Own

This is a summary of a phone conversation I had with a very nice older woman in a North suburb of Chicago. I will refer to her as Mrs. G:

Mrs. G: Thank you for the information on the Chimney Balloon. I hired a chimney sweep to come to my home so I could have him measure to fit a Chimney Balloon.

Jason: That is a great idea. I know you expressed concern about getting your old damper open as it has rusted closed. How did that work out for you?

Mrs. G: It went well but the chimney sweep suggested an Exhausto Chimney Fan so I can seal up my chimney. He said it would cost about $900 to install one.

Jason: Exhaust makes a very good product Mrs. G. but I thought you said you do not use this fireplace at all?

Mrs. G: I never use this fireplace but the sweep told me this was a good way to stop heat loss through the chimney.

Jason: Well the Exhausto does have a feature that tops the chimney when it is not blowing, but if you really want to top your chimney it would be best to just have the sweep cap the chimney with a top cap plug.

Mrs. G: The sweep told me that the Exhausto will keep me from losing heat out the chimney and act as a top sealing damper.

Jason: Yes, but primarily the Exhaust is made to draw air up the chimney. It is perfect if you had a chimney that did not draft well and you use it often. In my opinion, You would be better served to get a more economical top sealing damper, like the ones made by Lymance,  if you are looking to seal the fireplace at the top and you would like to still have the option of using it. If you don’t plan to use the fireplace and you never have, and if you have no known smoke draft problem, you would be wasting money by installing an exhausted. Is this Chimney Sweep someone that you know and trust.

Mrs. G: Well, this chimney sweep is from the yellow pages, I have not used him before. But he says he knows what he is talking about. He thinks this will work to create the right amount of air in my chimney so it won’t be cold anymore.

Jason: Mrs. G. I think this guy is trying to up-sell you and does not have your best interest in mind. I would call another sweep and have him look at your fireplace. Ask him if he thinks a Chimney Balloon or a top sealing damper would work best for you.

Mrs. G: Well I already have signed the estimate for the Exhausto so they are installing it tomorrow since they had a cancellation.

Jason: Mrs. G I would encourage you to call to see if you can have this guy let you out of that estimate. I really encourage you to have another person look at this first. We can look up some reputable chimney sweeps through the National Chimney Sweeps Association and get you another opinion.

Mrs. G: Maybe that would be good I will call him and call you right back

Jason: OK, in the meantime I will look up some reputable sweeps in your area. I will have you a few phone #s by the time you call back.

Mrs. G: OK Jason, thanks, goodbye.

Mrs. G never called me (Jason) back. I can only assume this chimney sweep talked her into the installation again. I didn’t care if she bought a chimney balloon or not. I actually thought a lock top damper may be what she wants. But I knew for sure an exhaust was going to be overkill.
