The Contemporary features a linear burner, halogen lighting mounted beneath the burner, and a black porcelain liner. The rich liner reflects the flames and the lighting. Decorative ceramic glass panels, available as an accessory, add visual interest to the fireplace interior and complement the flames. Use the remote control to raise or lower the lighting levels and the panels glow red along their edges.Accent Light Ceramic Glass Contemporary burner operates at 32,000 Btu input Dimmer-controlled Halogen lighting beneath the burner Porcelain black reflective liner Decorative Glass Droplets are requiredAir Shutter Opening - Front (LP): Full open Air Shutter Opening - Front (N): 9 16 Btu (LP): 31,500 Btu (N): 34,500 Depth: 15-13 16 Fuel Types: Liquid Propane, Natural Gas Gas Inlet Shutoff Valve (Pipe): 1 2 NPT Height without standoff: 24-1 4 Ignition Types: Intermittent Pilot Width: 51-1 16Consult your local building code agency, prior to installation, to ensure compliance with local codes-including permits and inspections.
