Critical Characteristic

1.If any of the original wire, as supplied, must be replaced, use the same equivalent wire. Wiring must comply with applicable codes, ordinances and regulations.

2.Field wiring must comply with applicable codes, ordinances and regulations. Use only Class 1 wiring inside furnace compartments.

Line voltage wiring:

UL AWM 1015/1230, 600V, 105°C, VW-1,12AWG; CSA TEW 600V, 105°C, FT1, 12AWG.

Low voltage wiring: same ratings as high voltage except 18AWG.

For the use of a two-stage heat thermostat or an outdoor thermostat, connect between W1 and W2. Make sure that the Season Select switch is set to the Mild Position.
