    Does this item have an option of being 34" x 28"?

    I noticed the Lock Top II damper attaches to the top of the chimney tile with silicone adhesive. How do you remove the unit in order to sweep the chimney from the top in order to clean it?
    3 Answers
    The cap attaches via a two step procedure that allows access to the chimney to sweep it after the fact. The cap will arrive with what is known as a Sweep's Ring. This is essentially a mounting plate and is the component that is secured to the chimney via the silicone sealant. Once the ring is attached, the remaining assembly is bolted to the outer part of the ring. Whenever you need to sweep, the cap is simply unbolted and set aside, with the ring remaining in position.

    Once the Lock-up II is installed by applying the silicone adhesive you cannot remove the chimney cap unless you are willing to reapply new silicon adhesive. Removing the cap is very easy with a putty knife. Make sure to scrape off all of the adhesive before reapplying the new stuff. You should definitely consider doing all of your chimney maintenance before installing the new cap.

    I just installed this exact unit about one week ago. It was very simple although I was skeptical about using only silicone adhesive to secure it but it seems to hold securely. To answer your question, you would have to remove the rain cap and mesh screen first by removing the four hex bolts that hold the assembly to the base frame which was glued to the chimney flue tile. Then, you might be able to clean the flue with the damper Lock-Top in the up position but you may have to remove that as well by removing the various screws that hold the spring wires to the base frame. None of this will be difficult, I wouldn't think, though I never removed the spring wires. I would recommend that, when you go to glue the base frame down to the top of the chimney flue tile, separate the rain cap / screen mesh, first, as this makes it much easier to handle the base frame and damper top when installing it. After the adhesive sets up for a bit, you can go back and re-bolt on the rain cap. Also, I did not install the cable bracket until 24 hours later because I did not want the pressure of the closed position to "squeeze" the silicone adhesive any more than what I applied to it during installation (and the natural force of gravity). The force required to securely close the Lock-Top is substantial which is probably a good thing in order to ensure that the top always tends to want to spring open upon releasing the handle as well as getting a good closed seal such that I was concerned it would squash down the adhesive if it had not fully cured yet. I simply let the cable dangle into the fire box and then, 24 hours later, I installed the bracket and adjusted the cable length to achieve the correct closed position for the Lock-Top. The whole process was easier than I anticipated. This is a great product which I needed in order to keep the fumes from the furnace flue from being drawn back down into the fireplace flue and down into my family room!

    from Atlanta, Georgia asked:
    December 3, 2013
    Can this be used with gas logs?
    1 Answer
    Manufacturers discourage the use of top mounted dampers with gas logs. The reason for this is due to instances where the damper was left closed by accident and combustion byproducts from the logs backed up into the room. Unlike a wood fire, there is no smoke to warn of a problem. Only use this damper if you have a guaranteed reminder system worked out to ensure the damper is opened each time. If there is any doubt that a reliable system can be worked out, I recommend avoiding this type of damper.

    We bought a house that the owner made the fireplace cap and we are wondering if it opens as far as it should. It appears to open a maximum of 5 or 6 inches. Is that OK?
    1 Answer
    The opening should have a minimum of 5 inches of opening height. As long as this measurement is met, the fireplace should draft properly.

    I installed this damper on my fireplace flue and I get a strong soot smell in my house when the damper is closed. Any idea what is causing the smell?
    1 Answer
    These dampers work so well at sealing your flue that the downside to them is that they allow any odors from your chimney to creep back into your room. A thorough cleaning of your flue should alleviate the soot smell that you are noticing.

    Eliminate cold drafts from your fireplace
    Installation was quit simple once you prepare and take things step by step....but I do have a single story home that can be walked on. Waiting for winter to use this yet.
    ProsStainless steel design and cage to protect the elevator cover should be an improvement in winter ice storm events.
    ConsFound difficult to get the hook adjusted for a complete seal. So I do have a tension spring I am going to install just above the handle a few inches so this should give a degree of variance for that hook with the cap in a sealed position.

    Best Product I've Come Across
    I have been in the business of construction for over twenty years, and this product is simply the best product out there of its kind. What was particularly impressive to me was the ease of installing it. Even more remarkable is how seamlessly the damper and handle are able to operate with one another. Probably the most amazing thing I found with regards to this unit is the price tag; in making the decision to purchase this product instead of other ones, I was able to save several hundred dollars and come away with a much better product.

    Eliminates Drafts
    If you are looking for a product that is able to function properly and live up to all of the promises as they are listed, then this item is just what you need to buy! Prior to installing it on our fireplace, we frequently had issues with drafts, all of which made our home uncomfortable. Once this was put in place, what amazed me is that all of the previous issues that we had with drafts immediately went away. Additionally, our heating bill literally plummeted.

    Very High Quality Product
    This product is a good one, and it possesses excellent quality overall. The design is such that you can expect for it to last many years of use; best of all, the service that it provides to our chimney in both eliminating unwanted drafts and keeping the rain out of the fireplace. One other arena that this unit has proven itself to be extremely useful is in keeping the heat inside the home and lowering heating (and electric) bills. The installation process is also one that is not cumbersome in the least. So efficient is the design that there is nothing included that needs to be fastened onto the chimney. My initial thought is that such a device as this would require something to fasten it to the chimney, and initially I was a bit apprehensive about this design. Thankfully, it has proven me wrong, as well as has proven itself to be an all around excellent product.

    What immediately stuck out in my mind is how effective the top chimney damper managed to lock into place. Best of all, the price is excellent and the quality of the stainless steel used to fabricate it is unsurpassed.

    Tight Seal on Damper
    This is a fantastic product that has done a terrific job. I installed it on one of my fireplaces, and because of the results I have managed to get, I really want to install it on my other fireplace. The choice to install this item on the fireplace has been so effective that I have found myself wishing that I had made the decision to purchase and install this product much sooner. The seal on this item is tight enough to ensure that it will not leak at all.

    Looks Amazing
    There are so many positive things to say about this product that it really is almost impossible to figure out where there best place to begin is. As a woman, I sensed that installing this on my own would be a little bit of a challenge, but amazingly so, it only took me about thirty minutes to do the entire installation. What really impressed me is that as soon as I was finished, the seal was so tight that I felt confident that it would not leak at all. Best of all, it looks quite nice as it sits on top of the chimney on my roof. All in all, it really is an outstanding asset.

    Very Efficient Design
    When it comes down to the installation process, this product is almost impossible to beat. It is extremely well made and all of the instructions needed to get the job done right were included. Even though I am happy with the results overall, there are a few things I definitely would recommend be changed. Primarily, there are some design flaws to be found in some of the framing and in the bracket. I basically would recommend a review of the materials that were selected for use to be sure that they are designed to work together in the most efficient manner possible, because that is not the perception that I have been left with as I work with it.

    Stopped the summer down drafts
    I have a ranch with a wood stove in the finished basement. In the summer I get stinky down drafts. This product solved that problem. Easy to install, it comes with everything needed. I would change the locking mechanism, thought. To close it you pull the cable and slide the chain into a bracket with a slot cut in it. The problem is, if you can't quite get a full link in the slot, you're forced to let open slightly to align the next link. Not a big deal but I'd change it to allow a positive closure every time.

    So far, so good
    It's a little early to review this item, since we just had it installed last week, but so far, so good. It seems to be made of quality materials, was simple to install & easy to use. Just be aware: we had someone install it for us. He glued it down, then came downstairs to set the pull-cord & show us how to use it. Wrong! The directions state that you should let the cement cure before you do anything. Unfortunately, the cap shifted from all this cord-tugging. When we looked at it later that day, it was no longer centered. My husband had to go back up & fix things as best he could. Couldn't move the cap, so all he could do was fill in the gaps with more cement. This is NO REFLECTION on the cap itself. Just telling you so that you won't make the same mistake we did. FOLLOW THE INSTRUCTIONS the company sends you.

    Damper Cap Combo does just what it is supposed to do.
    The original damper in my chimney was not functioning so I thought I would give this a try. Removing my old damper inside the chimney was just a dirty job. The existing chimmney cap was removed quite easily and still in great shape after a lot of years. (It was a quality stainless steel product similar to the construction of the Lock-Top). The quality of the new unit is excellent. Installation was a bit of a challenge as it was a windy day I suggest two people handle the install as you need to adhere the unit to the top of your chimney. Do not unwind the "cable unit" until you are ready to set the cap on the adhesive (it is a real pain to untangle). Instructions that were included could be much better written and clearer in overall content. I suggest only individuals who are handy attempt this as you need to prepare the surface for the adhesive and you will be working on a roof/ladder during the process. The selling price was best around and the unit functions just as it is designed. This is just the start of my first season with the item so I cant make any long term judgements at this point.
    ProsQuality of construction and Price
    ConsCable will tangle easily during install and instructions could use to be re-written with better graphics and directions.

    Instructions Could Be Clearer
    I am very happy with this product, specifically since it has managed to successfully eliminate all of the drafts that we had in our home. Overall, the room is significantly warmer now. One minor quibble that I have with this product is that the installation process was not at all straightforward. Thankfully, I did manage to locate a video on YouTube that did a great job of demystifying the installation process. One other minor problem I had was getting the coiled wire to cooperate and go where it needed to go. It took me almost a half an hour to get it all straightened out.

    As Anticipated
    I am quite thrilled overall with the quality of this product and the significant improvement it has given to my home as a result. This item arrived just as it had been described to me, and the installation was easy despite the fact that some of the instructions were not altogether clear. Our current home is a little unusual in that we actually live in an old farmhouse. Because of its design, it was quite easy to feel the drafts as they would come down our fireplace and into our home. However, once we had installed this product, we were able to notice a huge difference. Gone were the drafts that made our home very uncomfortable. Best of all, the heat was very easy to retain, keeping the house a comfortable temperature at all times.
