What Is The Vertical Measurement From Where Your Liner Will Start To The Very Top Of Your Chimney?
What Is The (ID) Inside Dimension Of Your Chimney Flue?
*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.

What is the (ID) inside dimension of the exhaust hole or collar?
Is the exhaust hole on the top of the stove or on the back of the stove?
*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.
Are you venting a hot water heater together?
What is the (ID) inside dimension of the exhaust hole or collar of your hot water Heater?
Are you venting a hot water heater only (no furnace or boiler)
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.
What are the height and width of the opening, front face of your fireplace?
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.
