ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONSPROCEDUREElectrostatic discharge can affect electronic components.Take precautions during furnace installation and servicing toprotect the furnace electronic control. Precautions will pre-vent electrostatic discharges from personnel and hand toolswhich are held during the procedure. These precautions willhelp to avoid exposing the control to electrostatic dischargeby putting the furnace, the control, and the person at the sameelectrostatic potential.1. Disconnect all power to the furnace. DO NOT TOUCH THECONTROL OR ANY WIRE CONNECTED TO THE CON-TROL PRIOR TO DISCHARGING YOUR BODY’S ELEC-TROSTATIC CHARGE TO GROUND.2. Firmly touch a clean, unpainted, metal surface of the furnacechassis which is close to the control. Tools held in a person’shand during grounding will be satisfactorily discharged.3. After touching the chassis you may proceed to service thecontrol or connecting wires as long as you do nothing thatrecharges your body with static electricity (For example: DONOT move or shuffle your feet, DO NOT touch ungroundedobjects, etc.).4. If you touch ungrounded objects (recharge your body withstatic electricity), firmly touch furnace again before touchingcontrol or wires.5. Use this procedure for installed and uninstalled (ungrounded)furnaces.6. Before removing a new control from its container, dischargeyour body’s electrostatic charge to ground to protect thecontrol from damage. If the control is to be installed in afurnace, follow items 1. through 5. before bringing the controlor yourself into contact with the furnace. Put all used ANDnew controls into containers before touching ungroundedobjects.7. An ESD service kit (available from commercial sources) mayalso be used to prevent ESD damage.INTRODUCTIONThe models 58UHV and 58UXV Series 100 Furnaces are availablein sizes 60,000 through 117,000 Btuh input capacities.These furnaces use variable-speed motors manufactured by Gen-eral Electric (GE) and known as ICM2+ motors. They areintegrated control motors, which include a pre-programmed micro-processor-based control to precisely control the selected airflowrates. The motor will be referred to as ICM2+ in the rest of thisdocument.The design of the upflow/horizontal gas-fired furnace is A.G.A.and C.G.A. design-certified for use with natural and propane gasesand for installation on combustible wood flooring, in alcoves,attics, basements, closets, or utility rooms. The design of thisfurnace line is not A.G.A. and C.G.A. design-certified for instal-lation in mobile homes, recreation vehicles, or outdoors.Before installing the furnace, refer to the current edition of theNFGC. Canadian installations must be installed in accordance withNSCNGPIC and all authorities having jurisdiction. For furtherinformation, the NFGC is available from National Fire ProtectionAssociation Inc. Batterymarch Park, Quincy, MA 02269; Ameri-can Gas Association, 1515 Wilson Boulevard, Arlington, VA22209; or from Literature Distribution.Installation must conform to the regulations of the serving gassupplier and the local building, heating, and plumbing codes ineffect in the area in which the installation is made, or in theabsence of local codes with the requirements of the NFGC orNSCNGPIC.Application of this furnace should be indoors with specialattention given to vent sizing and material, gas input rate, airtemperature rise, and unit sizing. Improper installation ormisapplication of the furnace can require excessive servicingor cause premature component failure.Table 1—Minimum Clearances To CombustibleMaterials (In.)UNIT SIZE 060 080—120UPFLOWFurnace Sides Single-Wall Vent 1 0Type B-1 Double-Wall Vent 0 0Furnace Back 0 0Plenum Top 1 1Furnace Front(See Notes)Single-Wall Vent 6 6Type B-1 Double-Wall Vent 3 3Vent Single-Wall Vent 6 6Type B-1 Double-Wall Vent 1 1HORIZONTAL POSITION (IN ALCOVE, ATTIC,AND CRAWLSPACE)Sides*‡ 1 1Back 0 0Top Single-Wall Vent 1 1Type B-1 Double-Wall Vent 1 1Furnace Front†(See Notes)Single-Wall Vent 6 6Type B-1 Double-Wall Vent 3 3Vent Single-Wall Vent 6 6Type B-1 Double-Wall Vent 1 1HORIZONTAL POSITION (IN CLOSET)**Sides*‡ 1 1Back 0 0Top Single-Wall Vent 2 2Type B-1 Double-Wall Vent 2 2Furnace Front(See Notes)Single-Wall Vent 6 6Type B-1 Double-Wall Vent 3 3Vent Single-Wall Vent 6 6Type B-1 Double-Wall Vent 1 1* The supply side must maintain 6-in. clearance from flue to combustiblematerials when using single-wall vent.† 18-in. front clearance required for alcove.‡ Indicates supply or return sides when furnace is in the horizontal position.Line contact only permissible between lines formed by intersection of top andtwo sides of furnace casing, and building joints, stud, or framing. Clearance toreturn side is a minimum of zero in.** J-box must be installed on lower (bottom) inside of furnace.NOTES:1. Provide 30-in. front clearance for servicing. An open door in front of thefurnace can meet this requirement.2. A minimum clearance of 3 in. must be provided in front of the furnace forcombustion air and proper operation.2
