Furnace Cement
Putting in a chimney liner is a job. Installing an antique Fisher insert has had its challenges. I ordered the cement to seal the vertical connector to the stove. As I inspected the fireplace I saw that the lintel and brick facing where the flue metal meets, there was a gap that needed filling. Heat had risen and stained the drywall above the mantle. A pint was to much Furnace Cement for sealing the liner to the stove therefore I had enough to fill the gap. Its a good product and if you need cement, you ought to buy with your order.
