The line contact is only permissiblebetween lines that are formed by the intersection of the top and twosides of the furnace and the building joists, studs or framing. This linemay be in contact with combustible material. Refer to Figure 10.When moving or handling this furnace prior to installation, always leavethe doors on the furnace to provide support and to prevent damage orwarping of the cabinet. When lifting the furnace, support the ends of thefurnace rather than lifting by the cabinet flanges at the return air open-ings (bottom or sides) or supply air opening.It is acceptable to use the primary heat exchanger tubes as a liftingpoint provided that the tubes are lifted at the front of the heat exchang-ers where attached to the vestibule panel. Do not use the top returnbend of the heat exchangers as lifting points as the tubes may shift outof position or their location brackets/baffles.SUSPENDED FURNACE / CRAWL SPACEINSTALLATIONThe furnace can be hung from floor joists or installed on suitable blocksor pads. Blocks or pad installations shall provide adequate height toensure that the unit will not be subject to water damage.Units may also be suspended from rafters or floor joists using rods, pipeangle supports or straps. In all cases, the furnace should be supportedwith rods, straps, or angle supports at three locations to properly sup-port the furnace. Place one support at the supply end of the furnace,one support located approximately in the center of the furnace near theblower shelf, and the third support should be at the return end of the fur-nace. Maintain a 6” (15.2 cm) minimum clearance between the front ofthe furnace and the support rods or straps.All six suspension points must be level to ensure proper and quiet fur-nace operation. When suspending the furnace, use a secure platformconstructed of plywood or other building materials secured to the flooror ceiling joists. Refer to Figure 11 for details and additional information.When moving or handling this furnace prior to installation it is recom-mended to leave the doors on the furnace to provide support and toprevent damage or warping of the cabinet.
