What kind of Kit do I need?
If you are installing a fireplace insert then you need our Insert Kit which in most cases will be a 6 inch diameter kit.
If you are installing a liner for a furnace, boiler, or free standing stove then you need our Tee Kit. Most of the time this calls for a 6 inch diameter kit. If you are installing the liner in an 8×8 flue, give us a call at 1-866-941-5112 so we can help you make sure your liner is going to fit before you buy it.
