The Dutch-designed Hwam 3055 Zero Clearance fireplace features a proprietary autopilot system that regulates three sources of combustion to achieve a 4.09-gram-per-hour emission rate. Intended for mid-height installations, the model sits nearly flush with the wall. The clear glass viewing area surrounded by a black glass frame opens upward, offering unobstructed access to the chamber. Hwam. 603.236.7045. www.hwamna.com.
