Instead of traditional logs, feast your eyes on the stainless steel fire tubes resting on ceramic fiber stones. The reflective black glass interior multiplies the fire and radiates the flames. There are two different sizes: The Lux 36 and the Lux 42 with 36″ and 42″ inch viewing areas – the largest in their class of zero clearance gas fireplaces. And if the stones as media don’t appeal to you, you have the choices of crystal glass (standard), cobalt glass, black glass or amber glass. Anti-reflective glass on the front provides 89% glare reduction. You also have two options for the front. Choose a firescreen front in black, graphite, or new bronze. There’s also the Modern front (pictured) available in black or light gray. Heat & Glo’s LUX36 zero clearance gas fireplace pumps out up to 38,000 BTUs and the LUX 42 puts out 49,000 . Both models have Heat & Glo’s IntelliFire Plus ignition system, so there’s no pilot to run up your gas bill. And the Lux zero clearance gas fireplaces are direct vent technology, meaning no room air is used for combustion. Rough framing specs: Lux36: 59 1/2″ wide x 56″ high x 24″ deep. Lux42: 65 9/16″ wide x 61″ h x 24″ deep.
