The Solution 1.8-I insert, as its name suggests, was developed from the same liner as Solution 1.8. The superior quality combustion and several other features are identical to its free-standing namesake. Solution 1.8-I comes standard with a powerful, heat-activated 120 CFM fan strategically positioned to redistribute the heat from the firebox into the room. It is designed to fit a face plate that can cover a masonry hearth up to 32 inches (81 cm) high and 50 inches (127 cm) wide. The door overlay can be matched to the face plate trims, which are available in black, brassy gold and nickel.
