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?
By eFireplaceStore on January 2, 2015
Answer: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.

Answer: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.

Answer: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!

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?

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.

Does this item have an option of being 34" x 28"?
By Brennan W. on January 5, 2017
Answer:Unfortunately, we do not carry one of these caps with those measurements.

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?
By Collin C. - NFI Master Hearth Professional on October 29, 2013
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.

Can this be used with gas logs?
By Collin C. - NFI Master Hearth Professional on December 3, 2013
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.

Unfortunately, not. We currently only offer this item with the 30' of cable. We do offer an extra hardware pack. You may view it by following the below link.
