Flush cast iron design

The cast iron front of the GMi70 is designed to fit flush with your hearth for a clean and elegant look.

Soapstone firebox

Burn 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.

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.
