Chimney Liner Top Plate Options

When you buy a chimney liner kit, it includes a top plate.  These top plates can vary in style and size.  It is very important to purchase the size you need.  Sometimes you can “make it work” and others times you cannot.  So it is best to do your research before purchasing.

Flat Top Plate

Flat top plates are just that, flat.  It is designed to sit flat on top of the chimney.  These are to be used when you have no terra-cotta flue extending above the crown or when you plan on removing the existing flue.  This style of top plates is not designed to sit on top of the flue.  The standard size is 13″ x 13″.  These are the outside measurements of the top plates.    Our flat top plates are also available in 13″ x 18″ and 18″ x 18″.  But any size is available upon request.

Terra-Cotta Top Plate

When you have a terra-cotta flue that extends out of the chimney, a terra-cotta top plate is suggested.  The top plate will wrap around the sides of the terra-cotta and secure to the outsides of the flue using 4 bolts that are adjusted tight to the flue.  Using this top plate is recommended when the terra-cotta is extending above the chimney because many times if you try to break the flue, it may crack the crown. terra-cotta top plate, chimney liner top plate  Terra-cotta top plates are available for all common flue sizes.

Deluxe Top Plates

Deluxe top plates come in either flat or terra-cotta style.  The only difference is that is has a square chimney cap built in.  The cap is hinged on one side that makes it a breeze for cleaning.  The deluxe top plates are the best looking top plates on the market.

    *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.

    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.
