Green wood can produce more creosote--a black sooty liquid which deposits and hardens on the inside of your chimney and can ignite, causing a chimney fire. When you stack your wood, you should stack it in an open location where the summer sun can warm it and breezes can help remove moisture. Be sure to cover the top of the wood pile to keep the rain out. It is important that you do not stack unseasoned wood in an unventilated area for it will not dry properly. You shouldn’t allow your firewood to lay on the ground for more than a couple days before stacking , or it will start to mold and rot quickly. Once your wood is seasoned, store it in a dry location before burning. CHIMNEY REQUIREMENTS A Class “A” HT 2100 All Fuel 6” Chimney Pipe and Base Plate should be used for the installation. See Illustration. Place the Base Plate over the flue outlet of the furnace and drill eight(8) pilot holes into the Cabinet Top. Apply a generous amount of high temperature sealant to the bottom of the base plate, and around the flue outlet. Position the base plate over the flue and secure with the eight(8) screws provided. Then attach the flue pipe sections. A minimum chimney height of 6 feet is required not including the rain cap. In order to determine proper chimney height above the roof, measure from the side of the chimney horizontally. As you move up the chimney, the length increases. Once this measurement reaches 10 feet, this is the base height of the chimney. The chimney must be 2 feet taller than the base height. If the chimney is closer than 10 feet from the peak of the roof, the chimney must be 2 feet taller than the peak of the roof. The 2 feet measurement does not include the rain cap. Once correct chimney height is achieved, check the chimney draft. It should not exceed 0.06 inches of water column. Then secure with three screws at each joint and attach guy wires down to the rings located around the top of the furnace cabinet. See illustration. CLEARANCES 22” 12” 20” 15” COMBUSTIBLE WALLCOMBUSTIBLE WALLFLUE(TOP VIEW) MINIMUM CLEARANCES TO A COMBUSTIBLE WALLCAUTION: DO NOT storecombustible orflammable materials or liquids near thefurnace. Sides of furnace, 12”; Rear of furnace, 15” (allow approximately 20” for the return box); Front of furnace, 36”; Heat Duct, 2” for the first 9 feet then 1” thereafter. CONNECTING HOT AIR DUCT TO FURNACE We strongly recommend that the hot air duct work be installed by a home heating specialist. If doing the installation yourself, before you decide which installation will best suit your needs, consult a qualified heating technician and follow his recommendations as to the safest and most efficient method of installation. The warm-air supply-duct system shall be constructed of metal in accordance with NFPA 90B, 2-1.1. The plenums installed to the furnace be constructed of metal in accordance with NFPA 90B, 2-1.3. Outside the house you must use 10 inch galvanized pipe, wrapped with weather proof, UV resistant insulation. The 12 inch return may be galvanized pipe and attached to the home so as to not pressurize the home. NEVER reduce the 10” hot air or the 12” return air as this will result in restricted air flow and cause the furnace to not operate properly. NEVER draw cold outside air into the blower housing. By doing so, the furnace’s heat chamber will not reach the necessary temperature to heat the home. The duct work should be designed so the external static pressure does not exceed 0.2 inches water column while developing air velocities of 600 to 1,000 feet per minute in the main trunk duct and 400 to 600 feet per minute at the registers. The heat outlet should never be less than ten inches (10”) round or 79 square inches. This furnace must be installed with a cold air return system. The system must be a minimum of twelve inches (12”) to readily transfer the cold air from the home back to the furnace. If desired, a cold air filter box may be constructed with a minimum opening of 225 square inches. The warm-air supply outlet of the outdoor furnace must not be connected to the cold-air-return inlet of an existing central furnace because the possibility exist of components of the existing furnace overheating and may cause the central furnace to operate other than intended. TYPES OF INSTALLATION NO DUCT WORK INSTALLATION Cold air return must be installed in all installations, even those without an air duct system. If you do not, the furnace will not be able to heat the home. A filter should be installed in the cold air return. Furnace filters should be checked and cleaned/replaced regularly. When there is no duct system to connect the furnace to, keep the following in mind: 1. You must separate the hot air duct from the cold air return. Ideally, locate each at opposite ends of the home. This method will work well in homes that are built on concrete slabs and should create a good air flow. If you do not, air will not flow evenly through the home. 2. In homes with a basement, you may ...
