Duluth Forge Dual Fuel Ventless Gas Fireplace Mantel
The Duluth Forge Ventless Gas Fireplace combines high-efficiency heating with sophisticated home styling. Engineered with patented Dual Fuel Technology, this unit operates on either natural gas or liquid propane and delivers up to 32,000 BTU of warmth, heating spaces up to 139.4 sq m. The furniture-grade fireplace mantel is finished in an elegant slate gray with dual pilaster moldings and subtle distressing, offering an upscale architectural accent to any room.
Equipped with a built-in thermostat control, the burner automatically cycles to maintain your desired temperature while operating at 99.9% energy efficiency without the need for an outside duct or chimney. Six hand-painted ceramic fiber logs produce realistic, radiant flames, backed by safety features including an Oxygen Depletion Sensor with automatic shut-off and reliable battery-assisted piezo ignition.
