The fire is started with our Auto-Start One-Touch Igniter, and the user-friendly digital Control Board helps you set the feed rate and blower speed to a setting that makes your home feel the most comfortable. The hopper holds a full, 40-lb. bag of pellets (plenty for overnight burns), and the unique, cast auger feed system feeds a firebox that can heat up to 1,500 sq. ft. It is also Mobile Home approved. Outside air hook-up is mandatory, and an Outside Air Kit is included with the unit (a value over $60). Window trim is also included.
