SAFETY CONSIDERATIONS Installation and service of heating equipment can be hazardous due to gas and electrical components. Only trained personnel should install or service heating equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils, or cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on heating equipment, observe precautions in literature, and on tags and labels attached to the unit. Follow all safety codes. Wear safety glasses and work gloves. Have a fire extinguisher available. 7. Remove 2 screws securing vent enclosure and remove enclosure. 8. Loosen hose clamp at vent pipe connection; disconnect vent pipe. Position vent pipe out of way. 9. Remove and discard mounting screws securing inducer assembly (motor and housing). Remove inducer assembly from furnace. The removal of the inducer assembly from the unit will require some amount of force to break the RTV sealant between the housing back and the collector box. 10. Loosen rectangular clamp on outlet elbow which secures it to inducer assembly and remove elbow. 11. Remove screw securing top mounting bracket and motor ground wire to cover plate. Save mounting bracket. 12. Lay inducer assembly on flat surface and remove left and right mounting brackets. 13. Remove remaining screws (7) securing motor assembly to inducer housing. Step 2–Installation of New Inducer Housing 1. Carefully clean old sealant from collector box outlet. 2. Lay new inducer housing on flat surface and install new cover plate gasket in groove around front opening. Before beginning any installation or modification, be sure the main electrical disconnect switch is in the OFF position. Electrical shock can cause personal injury or death.
