C (0902) LOCATOR BRACKET _ NAI L_,AFLEATHEAD SC R EWS FLOOR SUPPLY DUCT FIGUREtl : Duct Connector Screw Attachment INSTALLATION OF SCREW A'B'ACHMENT DUCT CONNECTOR 1, Make floor cut out as shown in Figure 9. 2. Determine the depth of the floor cavity from the surface of the floor to the top of the supply air duct and select the appropriate duct connector from the chart. 3. Place locating bracket (supplied with the duct connector) to the back edge of the floor opening. See Figure 11. 4. Apply a water based duct sealant to the 1/2"supply duct attachment flange of the duct connector. 5. Determine which of the four positions the duct connector best centers over the supply duct and insert it through the floor cutout. 6. When propedy aligned with the supply duct, secure the duct connector to the floor with nails, flat head screws or staples. 7. Use screws as required to secure the duct connector to the supply duct. 8. Cut out the opening to the supply duct. If sealant was not used, the instaner should tape the mating flanges to provide s good air seal. NOTE: Duct sealant and tape must be classified as meeting HUD Standard 3280.715, U.L. Standard 181A. If tape is used to provide a better air seal, it should be a type approved by the applicable national or local codes. NAILS, FLAT HEAD SCREWS OR STAPLES BEND TABS UNDER OPENING TO SECURE TO THE SUPPLY DUCT SUPPLY DUCT FIGURE t2 : Duct Connector Tab Attachment INSTALLATION OF TAB ATTACHMENT DUCT CONNECTORS 1. Make floor cut out as shown in Figure 9. 2. Determine the depth of the floor cavity from the surface of the floor to the top of the supply air duct and select the appropriate duct connector from the chart. 3. Place locating bracket (supplied with the duct connector) to the rear of the floor area for the furnace. See Figure 12. 4. Determine which of the four positions the duct connector best centers over the supply duct and insert it through the floor cutout. 5. Mark cut-out location on the supply duct and remove the duct connector. 6. Cut out the opening to the supply duct. 7. Bend tabs down through and back up under the supply duct. 8. Secure the duct connector to the floor with nails, flat head screws or staples. The duct connector is designed for use on ducts down to 12" in width. When using the connector on smaller width ducts, there will not be sufficientclearance to bend the tabs on two sides of the duct connector. In such cases the tabs may be attached to the sides of the duct by using sheet metal screws or other suitable fasteners. Holes for sheet metal screws are provided inthree (3) tabs on each side of the duct connector. If more than 3 tabs need to be used to provide a more secure and air tight connection, the remaining tabs can also be fastened to the duct with screws after drilling the required screw holes.

FIGURE 13 : Installation of Furnace INSTALLATION OF THE FURNACE Remove the front panels and set the fumaca onto the duct connector. Slide it back until the rear of the unit engages the Iocator bracket. 2. Secure the front of the furnace with two screws at the mounting holes provided. 3. Secure the top of the furnace to a structural member using screw through the strap at the back of the furnace. Strap may be moved to any of the holes located along the top back of the furnace. Installer may provide an equivalent method, such as screws through the casing side. COMBUSTION LA, CAUTION] The inner flue pipe must...
