Named for the historic bay where Lewis and Clark wintered on the Pacific, the Astoria Bay™ large pellet insert is the ultimate culmination of design and function. Easy to start, easy to operate and easy to maintain. The Astoria Bay is designed to turn your inefficient open fireplace into a power house home heater (45,100 BTU/Hour). Adjust the feed rate to low and with the maximum fuel load (82 lbs.), you can expect up to 52 hours of continuous heating. Use the provided wall thermostat and stretch the burn time even longer.
