DO NOT USE HEARTH AND PATIO!!!! CHIMNEY FIRE NEW YEARS EVE. I have had my logs for less than two years. 1) purchase, glad to take my money 2) installation, two weeks late,and according to responders, improper flue installation, TWO times, causing heat to go up chimney (they didn't even use fire proof sealer) causing fire. When installer was ask about cleaning chimney, he said not necessary. Had them out to inspect for smell, then said i needed it cleaned, and more money. I HAVE NEVER BEEN SO UNSATISFIED just trying to enjoy a fire.
