Do you have or are planning on installing a pellet stove into an existing chimney?  This is a great idea to take advantage of a chimney that already exists.  But you may think since the pellet stove has an exhaust fan there is no need for a stainless steel chimney liner.

Well for the stove to work properly, it needs to be vented into a proper sized chimney.   In most cases the vent pipe on a pellet stove is 3 inch.  If you are installing a stove and venting it into a masonry chimney a 4 inch liner is recommended.   Whenever you go vertical with a pellet stove, 4” is recommended.

The best chimney liner would be a 304L rigid liner.  This rigid chimney liner is specifically designed to handle wood burning appliances only.  Since it can only handle wood creosote, the price is considerably less than 316L chimney liner.

This rigid liner will be the best choice for your pellet stove.  It will be the easiest chimney liner to clean and give you the best performance possible.

In some cases it may not be possible to use a rigid chimney liner, for example when the chimney has a bend in it.  What is recommended in this case is smooth inner wall chimney liner.  A corrugated chimney liner that does not have a smooth inner wall will not give you the best performance for a wood burning appliance.








    *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.
