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.
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.
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.
