Green Mountain 90 Insert by HearthStone
Wood Burning Fireplace Insert
HearthStone’s large flush wood fireplace insert combines stylish cast iron with their signature soapstone lining. The GMi90 burns up to 20 inch logs in the soapstone lined firebox. Soapstone retains the maximum heat from you fire and radiates steady warmth as your insert burns. HearthStone’s non-catalytic wood insert is easy to use. A single lever air control lets you burn hot and fast or low and slow to keep warm through the night.
