Green Mountain 70 Insert
About the Green Mountain 70 Insert
The GMi70 has been designed to fit flush with your hearth. It has a clean yet traditional style that complements many styles of home decor.
The cast iron front of the GMi70 is designed to fit flush with your hearth for a clean and elegant look. Burn up to 20 inch logs in the soapstone lined firebox. Soapstone retains the maximum heat from your fire and radiates steady warmth as your insert burns. Our 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.
