SETTING THE FLOOR FURNACE Lay aside the grill and package containing the thermostat, wires, etc., grasp two opposite sides of the outer casing and lower the floor furnace gently through the opening. Support the furnace evenly by the flange at the top of the outer casing. Trim back carpet, padding, and other types of floor covering so that the entire flange rests directly on the floor. If not evenly supported on all four sides, stresses may be created that cause excessive expansion and contraction noises as the floor furnace heats and cools. Anchor the floor furnace in place by driving two galvanized roofing nails through each side of the outer casing into the double headers approximately 1 inch below the flange. Place the grill into position making sure it lays flat against the outer casing flange. Leave the grill in place until time to light the furnace to keep occupants from falling into the furnace. Page 5 FURNACECASING GASKET MATERIAL DRAFT HOOD FIGURE 6 INSTALLING THE DRAFT HOOD The draft hood must be installed in the same atmospheric pressure zone as the combustion air inlet. The draft hood is packed in its own carton within the master pack. Make sure the draft hood received is the correct one for the floor furnace being installed. Included in the carton are two rope-like gaskets and 7 sheet metal screws. Begin by pressing the rope-like gasket material into the groove provided around the two male vent outlets on the floor furnace. See Figure 6. Slip the two female couplings in the draft hood over the male outlets extending through the outer casing, making sure the gaskets remain in place. Press the draft hood tight against the casing and use the 7 sheet metal screws to secure it tightly. All 7 screws must be used to prevent leakage of vent gases. Never install or operate a floor furnace without a draft hood. To do so could result in serious injury, property damage or death. CONNECTING THE VENT Refer to the specifications on Page 2 for the correct vent pipe size. Familiarize yourself with local codes or contact authorities to determine the approved material and method of installing the vent. NOTE: An existing vent that has worked for years may not be adequate for todays design because of higher efficiency requirements that result in lower stack temperatures. Improper or unsafe venting presents a hazard that may result in property damage, bodily injury or loss of life. Listed below are some guidelines to observe when installing the vent system. 1. Never reduce the vent pipe to a size smaller than the outlet on the draft hood. 2. Never run pipe more than 15 feet horizontally. 3. The total horizontal run of a vent plus the horizontal vent connector shall be not greater than 75 percent of the vertical height of the vent. 4. Slope horizontal pipe upwards at least . inch per lineal foot. 5. Do not use more than one elbow. An elbow restricts the flow of vent gases by approximately 10%. 6. Use a noncombustible thimble when connecting vent pipe to a masonry chimney. 7. Do not insert vent pipe farther than . inch into the interior of the chimney. 8. Single wall pipe must not be used. 9. Never connect the vent pipe to any chimney or vent system serving a solid fuel-burning appliance. 10. If another appliance is being vented through the vent system with the floor furnace, the vent pipe must be increased to compensate for the additional load. 11. Never install any kind of damper in the vent system. 12. Do not use transite or any other type of ceramic pipe for venting. Class “B” double wall pipe is acceptable to most codes, and if installed in accordance with the pipe manufacturers instructions provides the safest and most efficient vent system. Class “B” pipe has an integral lock for securing sections together. These locks must be properly fitted together. Fasten pipe to draft hood using at least three self-tapping sheet metal screws at equal intervals around the circumference of the pipe. Support horizontal pipe at three-foot intervals with metal strapping attached to joists. The floor furnace you have selected was carefully designed to operate both safely and efficiently when vented with the proper size vent listed for each furnace on Page 2 of these instructions. We do not recommend doing so, but if you must vent into a masonry chimney use the following instructions. Continued – next page Page 6 CONNECTING THE VENT - Continued 1/4” SAFE UNSAFE RECOMMENDED FIGURE 7A FIGURE 7B FIGURE 7C If the floor furnace is vented into a masonry chimney, the chimney must be inspected to determine that it is clear and free of obstructions and that it is safe for the intended use. The inside of the chimney must be at least 6 inches in diameter or 6 inches by 6 inches if rectangular. Insert the vent pipe into the chimney through a masonry or noncombustible corrosion-resistant thimble of the correct diameter. Do not push the pipe farther than . inch into the inside of the chimney. See Figure 7A. Pushing the pipe farther into the in...
