Yellow and Black is No Good for Chimneys
by: Clay Lamb

When you think of a bug problem in a home, some of the most frequently occurring images that come to the minds of homeowners are ants and termites. Although these pests are certainly a problem, bees that enter the home through a chimney can be of an issue as well. If you are having difficulties keeping such flying insects out of your home, you may want to consider installing a top sealing damper to your chimney.

Chimneys are a dry and safe place for bees, and if the chimney is not used often or at all, there is nothing inhibiting them from occupying it and eventually entering the home. A regular stainless steel cap will provide your chimney with the protection it needs to prevent critters from entering and keep birds from depositing flammable nesting material which can catch fire and cause a fire in the flue of the chimney.

Top Sealing Damper

These regular caps, however, will not prevent any insects from entering. Sometimes, the openings in the mesh wiring surrounding the chimney cap are wide enough to permit entry to insects such as bees and wasps. Getting rid of bees once they have moved into a chimney is difficult and requires professional workers. Often times pest control is needed, and a phone call to these companies usually comes with a very large bill.

Prevent all of these issues with a damper that will seal at the top when it is not in use. Not only will a top sealing damper help with climate control in your home by keeping heated and cooled air in the home, it will eliminate the possibility of bats squeezing through the openings in the mesh and prevent dangerous insects such as bees from making a home as well.

These top sealing dampers not only save you money on your energy bill, they allow you the peace of mind that comes with knowing that nothing is inserting dangerous nesting material into your chimney that could cause a fire to occur in the flue system of the chimney. If a chimney fire occurs, often times there will be damage to other parts of the home as well, making for a very costly repair that is life threatening to those who live inside the home.








    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If there is a terra cotta clay flue liner, does it protrude out of
    the top of the chimney at least 2 inches? If there are at least 2
    inches and the terra cotta clay is in good condition, you will use
    our stainless steel, terra cotta top plate that has a 1 1⁄2inch edge
    that goes all the way around (like a shoebox lid).

    *If your terra cotta clay flue is in bad shape at the top, you may
    need to just take a hammer and tap all around that terra cotta,
    taking it away to make the surface flat at the top of your chimney.
    In that case, you will simply use the flat top plate that comes with
    our liner kit.



    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If it is on the back of the stove, is it parallel with the back of the stove or is it at an angle, like 45 degrees?

    *If it is at an angle you will use an insert stove adaptor (an insert liner kit) rather than a two-part tee with cleanout cap.


    Usually pellet stoves have an exhaust hole id of 3 inches. However, if you are going up more than 15 feet to the top of your chimney you need to use a pipe and/or flex liner that is 4 inches diameter.





    If you are only venting a hot water heater then the exhaust hole diameter is probably 3 inch diameter. If it is 3 inch diameter and you are going up more than 15 feet to the top of your chimney, you must use a 4 inch diameter flexible liner or ridged pipe for proper draft. We also suggest to go ahead and use a 4 inch diameter flexible liner or ridged pipe even if the total length is 15 feet or less.


    Not the depth or any other dimension inside your fireplace.

    Most gas log fireplaces require an 8 inch liner kit or rigid kit. But do not assume that is the case for the gas log fireplace kit you are installing. Obey the requirements for that specific unit that are in your installation/instruction manual.
