Note 1: For American Standard/Trane, York PCLU and York P3UR furnaces: Install the black wire labeled "10" from pin 5 to pin 11 of the
12-pin harness which is connected to the furnace.
Note 2: There are some Rheem/RUUD furnace models which performed flame sense differently. Please read the information below before
testing the furnace!
1. Rheem/RUUD furnaces without a separate flame sensor will require the purchase of a Rheem flame sensor kit (62-24044-71) to be wired to
pin 7 of the 9-pin harness which is connected to the furnace.
2. Rheem/RUUD furnaces with a separate flame sensor which is NOT routed through the 9-pin harness will require removal of the flame
sensor wire from the existing connection and rewiring it to pin 7 of the 9-pin harness which is connected to the furnace.
3. Rheem/RUUD furnaces which have a separate flame sensor already routed to pin 7 of the 9-pin harness will not require this modification.
Connect the other end of the furnace harness into the ICM2812 harness labeled "2", connect the other end of this harness to the ICM2812
circuit board and connect the orange wire to the "FS" (flame sensor) terminal.
