Knockouts are provided in box and cabinet to run wiring. See figures 26 and 27. 2-Remove cap from knockout in blower deck on the same side as the installed make-up box. iii::i:: i................. j A IMPORTANT A field make-up box is provided for line voltage wiring. Line voltage wiring to unit is done through the J69 jack from the field make-up box to plug P69 from the control box. See figures26 and 27 for make-up box installation. Page 16 3-Electrically ground unit in accordance with local codes or, in the absence of local codes, in accor dance with the current National Electric Code (ANSI/ NFPA No. 70) and in Canada with the current Canadian Electric Code part 1 (CSA standard C22.1). The ground wire is provided in the field make-up box. To ensure proper grounding of the furnace, two star washers are included in the electrical make-up box bag assembly. Place the star washer on secudng screw before installing the make-up box. Make sure the star washer breaks the paint on the cabinet so that the washer is touching metal. Unit is not properly grounded if paint has not been removed by star washer. 4-An optional 120 volt accessory wira is provided with G32 units. Install the brown accessory wire into J69 jack plug by inserting the pin of the brown wire into the open socket of the INSYALUNG BROWN jack. See figure 25. Any ACCESSORY WIRE TO J69 accessory rated up to 4 BROWN amps can be connected to this wire. Connect the neutral leg of the accesso- NEUTRAL ry to the neutral white wire in the make-up box. The BLAC accessory terminal is en-WNIT_ ergized whenever the blower is in operation.

If furnace is being used with heat pump refer to FM21 installation instruction. NOTE -W2 thermostat connection (pigtail) must be made at two-speed control board. SureLight TM board is not equipped with a W2 terminal 10 -Install a separate disconnect switch near the unit so power can be turned off for servicing. 11 -Complete wiring connections to equipment using wiring diagrams provided with unit and in figures 32 and 33. Use 18-gauge wire or larger for thermostat connections. 12-The two-stagerelay board controls first-and second- stage furnace operation providing maximum comfort and efficiency. The furnace may be controlled by either a single-or two-stage room thermostat. 13 -The blower will run on continuous fan speed with the low speed tap connected to the (ACB LOW) 120 volt terminal and the thermostat set to "FAN ON" when there is no call for heating or cooling.
