Apply joint compound (pipe dope) sparingly and only to the malethreads of each joint. The compound must be resistant to the actionof propane gas.Install an accessible manual shutoff valve upstream of the furnacegas controls and within 72 in. of the furnace. A 1/8-in. NPTplugged tapping is provided on the gas valve for test gageconnection. Installation of an additional 1/8-in. NPT pluggedtapping, accessible for test gage connection, installed immediatelyupstream of the gas supply connection to the furnace and down-stream of the manual shutoff valve, is not required. Place groundjoint union between the gas control manifold and the manualshutoff valve.Use the proper length of pipes to avoid stress on the gascontrol manifold. A failure to follow this warning can causea gas leak resulting in a fire, explosion, personal injury, ordeath.Use a backup wrench at the furnace gas control whenconnecting the gas pipe to the furnace to avoid damaging gascontrols or manifold.Never purge a line into a combustion chamber. Never usematches, candles, flame, or other sources of ignition for thepurpose of checking leakage. Use a soap-and-water solutionto check for leakage. A failure to follow this warning cancause a fire, explosion, personal injury, or death.Step 7—Electrical Connections115-V WIRINGRefer to the unit rating plate or Table 5 for equipment electricalrequirements. The control system requires an earth ground forproper operation.Do not connect aluminum wire between disconnect switchand furnace. Use only copper wire.Make all electrical connections in accordance with the NationalElectrical Code (NEC) ANSI/NFPA 70-1996 and local codes orordinances that might apply. For Canadian installations, all elec-trical connections must be made in accordance with CSA C22.1Canadian Electrical Code, or authorities having jurisdiction.Fig. 11—Heating and Cooling Application Wiring Diagram 1-Stage Thermostat and Condensing UnitA95236115-VOLT FIELD-SUPPLIEDFUSEDDISCONNECTJUNCTIONBOXCONTROLBOX24-VOLTTERMINALBLOCKTHREE-WIREHEATING-ONLYFIVEWIRENOTE 2NOTE 11-STAGETHERMOSTATTERMINALS FIELD-SUPPLIEDFUSED DISCONNECTCONDENSINGUNITFURNACECOMRW C Y R GGNDGNDFIELD 24-VOLT WIRINGFIELD 115-, 208/230-, 460-VOLT WIRINGFACTORY 24-VOLT WIRINGFACTORY 115-VOLT WIRINGConnect Y/Y2-terminal as shown for proper operation.Some thermostats require a "C" terminal connection as shown.If any of the original wire, as supplied, must be replaced, usesame type or equivalent wire.208/230- OR460-VOLTTHREEPHASE208/230-VOLTSINGLEPHASEWHTBLKWHTBLKW/W1W2Y/Y2GNOTES: 1.2.3.Table 5—Electrical DataUNIT SIZEVOLTS—HERTZ—PHASEOPERATINGVOLTAGE RANGE MAXUNITAMPSMINWIREGAGEMAX WIRELENGTH (FT)‡MAX FUSE ORHACR-TYPECKT BKR AMPS†Max* Min*060-12 115—60—1 127 104 10.1 14 36 15080-16 115—60—1 127 104 10.6 14 34 15100-20 115—60—1 127 104 12.6 14 29 15120-20 115—60—1 127 104 13.9 14 26 15* Permissible limits of the voltage range at which the unit will operate satisfactorily.† Time-delay fuse is recommended.‡ Length shown is as measured along wire path between unit and service panel for maximum 2 percent voltage drop.9→
