About the Green Mountain 40

Warm your living area with a clean, efficient, long-lasting fire in a clean-traditional Green Mountain wood stove.

Our GM40 wood stove is styled with clean lines and offered in traditional black cast iron. Built for the wood stove purist. Our Green Mountain stoves exceed EPA clean burning standards. You can be sure they will burn clean today and for many years to come. The GM40 is lined with soapstone blocks. Soapstone absorbs the heat of the fire to give you long-lasting comfortable heat.
