OUR FIREPLACE HAD BEEN CLOSED UP FOR 30 YEARS & CHIMMY CLOSED. PUT THE INSERT IN & LOVE LOVE IT. LOOKS BETTER & MORE REAL THAN THE GAS FIREPLACES. LOVE THE WAY THE LOG EMBERS FLICKER. WE DON'T USE IT FOR HEAT, JUST LOOKS. WISH WE HAD HAD IT ALONG TIME AGO. WE HAVE THE DELUXE INSERT WITH LED LITES. HAVE HAD IT 4 MONTHS AND MAKES THE COLD WINTER SEEM SO WARM AND COZY!!!
