The Superior DRL4000 Series is a direct vent linear gas fireplace for natural gas, featuring ceramic glass, reflective black crushed glass media, and a clean-face design for contemporary installations. The DRL4000 Series brings a bold linear fire presentation to modern and transitional interiors. Flames rise across a wide burner through reflective black crushed glass media, creating a sleek and visually striking focal point. Its clean-face design and black painted interior keep attention on the flame display, while the large viewing area enhances the overall presence of the fireplace in open living spaces. Available in multiple large linear sizes, the DRL4000 Series can be integrated into a wide range of wall installations. Optional see-through configuration kits allow the fireplace to serve two rooms, creating a shared focal point between living areas. For select models, an indoor/outdoor see-through option allows the fire to be enjoyed from both inside and outside the home. Optional HeatFlo(TM) heat management kits help direct warm air away from sensitive wall décor placed above the fireplace. The DRL4000 Series uses a sealed direct vent system that draws combustion air from outside and vents exhaust gases outdoors. This system supports safe operation while maintaining indoor air quality. The fireplace features a clean-face design with integrated tile stops to simplify finishing around the installation. Optional see-through conversion kits allow installation between two interior spaces, while select models support indoor-to-outdoor viewing. Professional installation is recommended to ensure proper venting, gas connections, and compliance with local building codes. Electronic IPI/CPI ignition with seamless battery backup allows the fireplace to continue operating during power outages. The reflective crushed glass media creates a modern flame presentation, enhanced by the black painted interior and ceramic glass viewing area. Optional blower kits can help distribute warm air throughout the room, while optional multi-function remote controls provide convenient adjustment of fireplace operation. The durable powder coat finish supports long-term reliability and performance.
