Our large flush insert combines stylish cast iron with our signature soapstone lining.
The flush cast iron front of the GMI 90 is available in matte black or our brown enamel finish.
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.
