Aspen Insert

The Aspen Insert is the perfect choice for improving the efficiency of your small fireplace. At just over 18″ tall, the Aspen will fit in most of the smallest fireplaces. The Aspen is approved for installation into both masonry and factory built (zero-clearance) firepalces with the use of a 6″ stainless steel flue liner. The full double-wall construction of the Aspen maximizes heat to the room by trapping the heated air around the firebox and only letting it escape to the front, inside the home. The adjustable depth surround panel eases the installation by adding flexibility, and the optional blower adds in more circulating power.
