electric circuit. The furnace must be electrically grounded in accordance with local codes or in the absence of local codes with the National
Electrical Code, ANSI/NFPA 70 , if an external electrical source is utilized. The integrated furnace control is polarity sensitive. The hot leg
of the 120V power supply must be connected to the black power lead as indicated on the wiring diagram.
