    Fireplace Chimney Dampers, Parts, and Accessories

    Your fireplace brings warmth and beauty to your home, but what you and many others may not realize is that your fireplace chimney can cause some major energy inefficiency in your home. That is why chimney dampers are so essential. Chimney dampers are an often overlooked device allow you to close off your chimney flue when your fireplace is not in use, which keeps the heat, and even air-conditioned air, from escaping up the chimney. One of our top sellers is the Vestal Cast Iron Fireplace Damper Plate, whose rotary styled controls are easily controlled and operated by one of your fireplace pokers. Your chimney damper is installed by simply sliding it into place. This particular model is for a standard 36-inch flue.

    Are there any electric dampers for gas logs designed with shielded wiring harnesses that can be ran through the chimney pipe instead of trying to feed wire through walls, etc?
    1 Answer
    We are not aware of any product matching this description. If you are installing vented gas logs in a masonry or prefabricated wood burning fireplace, you should remove or affix the damper open and not use any top-sealing damper system of any kind.

    I read that a lock top damper should not be used in gas log fireplaces. Why? Is that a requirement or a recommendation?
    1 Answer
    This is because a damper should never be used with a gas log set, as the house will fill with carbon monoxide if the set is turned on but the damper is accidentally left shut. All vented log sets come with a damper clamp to make sure that any operational damper is left open at all times.

    One disadvantage of a top mounted chimney damper is the possibility of it freezing shut during the winter. Some models have a special mechanism that helps break the ice and dislodge a frozen damper. Our Chimney Cap and Damper combos are made with the lip designed to keep water from pooling on top of your damper and lowering the risk of it freezing shut.

    I am looking for a replacement damper plate 35'' x7'' (right side handle).
    1 Answer
    The damper plates we offer are replacement plates for the full Vestal damper assemblies we also offer and will not have the same specifications as your existing damper.

    I removed a Buck Stove insert from my masonry fireplace. When this was removed it left an open "hole" for air to pass in and out of the chimney. How do I know if I need a damper or just a damper plate? The insert was in the fireplace when I purchased the house.
    1 Answer
    If the cast iron damper framework is already there, you would simply measure the opening of the damper assembly. We only offer replacement damper plates for the Vestal dampers we offer here, so there would be no way to ensure the plates we offer would be correct.

    I am in need of replacement throat damper for brick fireplace. The opening is 33.5" x 6". The location of the damper hinges has rusted.
    1 Answer
    If the actual damper frame is rusted out, it may be a good idea to simply replace the entire damper assembly. You may be able to use the Vestal Cast Iron Fireplace Damper Plate - For 42 Inch Dampers as a quick fix, but this is made to fit only the 42" Vestal damper assembly we also offer so it likely will not provide a snug fit.

    I have a home from the mid 1940's, and would like to add a top mount damper to the flue. The flue appears to be constructed of rectangular, verified clay. The dimensions are 15-3/8" inside to inside length (17" outside to outside length) and 6-3/4 inside to inside width (8-3/8 outside to outside width). Do you have a model that fits this arrangement?
    1 Answer
    The Lock-Top 8 in. x 17 in. Energy-Saving Chimney Damper would indeed work with these measurements.

    We have a missing damper plate in our fireplace. The actual opening measures 28 and 13/16" x 5 3/4". I assume we'd need something a bit longer on both measures, right? Do you have a replacement plate that might fit?
    1 Answer
    The Vestal Cast Iron Fireplace Damper Plate - For 36 Inch Dampers measures 7" D x 28 3/8" W, but please note that this product is a replacement damper plate for Vestal dampers and may not fit properly with your damper.

    I would like to control the damper from outside of the fireplace with a crank type of system, including a chain to pull down to close and open the top of the chimney cap. I need to pull down from inside of the firebox or fireplace. Is there a product out there for this application?
    1 Answer
    Unfortunately, I do not have access to a crank style damper system like the one you seek.

    I just bought a house with a decorative gas fireplace that has a 6 inch metal vent. It does not have any type of damper on it and when the wind blows it comes into the room. Is there something I can have installed to stop the air infiltration or do I just need to plug the vent and not light the fireplace? It is a Majco model GBU36 fireplace.
    1 Answer
    Unfortunately, many of the older B vent gas fireplaces suffered from this issue. There is a built in draft diverter that is supposed to cure the issue, but it is not entirely effective. A high wind cap can be added to the vent system or a custom draft diverter fitted over the cap, but if you do not plan on using the unit, you could indeed pack insulation into the vent opening. If you go that route, it will need to be made known to anyone who may try to burn the unit in the future.

    How do you determine what size damper you need? Can a novice replace the handle?
    1 Answer
    The damper throat should be sized to the width of the fireplace opening. If the opening is sized between the castings available, it should be sized to the closest casting step. The handle itself is usually simple to replace. Most models simply have a drive pin holding the handle in place, but it differs from design to design.

    Looking for a replacement damper plate. I do not have the old plate. The measurements inside the opening are 4 1/4" x 35 1/2".
    1 Answer
    We do carry replacement damper plates, but they are specific to the Vestal brand of dampers and as such, we do not have one that matches your size requirements. The plates we carry are not easily modified, as they are cast from grey iron. If you are not able to see a name on the damper throat, the best option would be to have a damper plate cut from 1/4 inch plate steel that matches your sizing requirements. The only other option would be to remove the entire damper throat and replace the assembly with a new one.

    I am renovating a house that has two fireplaces, but both lack dampers. Do you have, or can you recommend, a guide for the builder/owner on how to size and install dampers?
    1 Answer
    As a standard, the damper throat should be the same size as the front width of the fireplace opening. As such, a Vestal 36 Inch Cast Iron Throat-Style Fireplace Damper would be the proper size to use for a 36 inch fireplace. Most damper assemblies are held in position with a layer of parging mix. If you have an existing damper that has rusted badly or otherwise needs replacement, it will need to be removed by using a cold chisel and hammer to break the existing parging mix loose. After removing the existing damper and any remaining mortar, the new assembly can be put into position and new parging mix used to secure it. If the new damper does not sit upon a brick ledge, you may need to construct temporary 2 x 4 supports to hold the damper assembly in position while the parging mix sets. A good parging mix to use is the Ahrens Chamber-Tech 2000 Smoke Chamber Parging Mix.
