A new stainless steel chase cover.

A chase cover is a metal covering designed to keep elements like rain and snow, from entering the home via the chimney chase.

Over time almost all non stainless steel pre-fab chimney chase covers rust due to the elements. Snow, ice and rain gets trapped on top of your chase cover and starts the decaying process. Leaves and pine straw also mixed with the moisture creates an acidic condition and breaks down the galvanized coating.

When this breakdown occurs the chase cover begins to pit. This will allow water to drip inside your chimney. Let this rust stain be your sign that it is time to replace your chase cover.

It is recommended when replacing your chase cover to use stainless steel. Stainless steel is more durable, stronger and will look new for a longer period of time. It is also recommended that it be designed with a cross break which creates a “dome” effect. This will prevent the snow, ice and water from pooling on top of your cover. Stainless steel chase covers may come with a lifetime guarantee against rust and corrosion.

If you want to protect your home from water damage it is highly recommended that you inspect the chase cover and if in an undesirable state, replace it immediately.








    *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.
