We design every fireplace using the best available technology and build each one to the highest-quality standards in Empire manufacturing facility in Belleville, Illinois. We make most of Empire components - from cutting steel to forming to welding to painting - and then hand assemble each fireplace to ensure the best fit and finish. For purchased parts, we give preference to North American suppliers - including Empire hand-painted log sets, Empire tempered and ceramic glass, the paint and powder coating, and even the packaging we use to protect Empire products until they reach your home. The result is a fireplace thats built to last by experienced craftsmen and craftswomen - a fireplace thats as deeply rooted in history as fire itself.Stainless Steel Slope Glaze Flair Burner Banded Brick Ceramic Fiber LinerAir Shutter Opening (LP): Full Open Air Shutter Opening (N): 3 16 BTU (LP): 27,000 - 35,000 BTU (N): 25,000 - 35,000 Fuel Type: Natural Gas, Liquid Propane KWH (LP): 7.30 - 10.15 KWH (N): 7.30 - 9.57 Weight: 112
