To begin properly sizing a fireplace liner, you first measure the fireplace opening width and height. The proper term is firebox opening. Note: the measurements need to only include the actual opening, not any obstructions. To clear this up, think of a phone where if you measure the screen size and phone size they will differ. The second aspect that must be measured when sizing a fireplace liner is the liner height. Note: this is ONLY the height of the liner and does not include an extra distance in the smoke chamber, firebox or fireplace opening, or height added with a chimney cap. Once these measurements are finalized the numbers can be put into a fireplace sizing guide calculator. Our choice of the calculator is http://www.chimneylinersusa.com/info-sizeliner.shtml
Fireplace Liner Sizing Process
Fireplace Measurements
Let us do a test run on sizing a liner. We measured our firebox or fireplace opening by inches to the dimensions of 35” wide and 25” high. Additionally, we accurately measured the liner height by feet to the height of 25’. These numbers are then plugged into our liner calculator that is linked above. These numbers will generate the required square inch area of the liner opening that is required and simplified by what diameter your liner should be.
