Fuel Considerations SHELLED CORN (Dry, preferably corn with 11% or less moisture content) • Optimum moisture content of corn should be 11% or less. Wet corn will rapidly deteriorate furnace components, reduce efficiency and void all warranties. Purchase a moisture tester if in doubt. • Corn must be clean and free from debris. Never burn corn right from the field. Damage caused by dirty corn is not covered by the product warranty. Ask for clean filtered bagged corn only. Stalk parts, excessi

Installation THROUGH THE WALL INSTALLATION (RECOMMENDED INSTALLATION) To vent the unit through the wall, connect the pipe adapter to the exhaust motor adapter. If the exhaust adapter is at least 18-inches above ground level, a straight section of pellet vent pipe can be used through the wall. Your furnace dealer should be able to provide you with a kit that will handle most of this installation, which will include a wall thimble that will allow the proper clearance through a combustible wall.
