Notes:
1. Ratings are shown for elevations up to 2,000 feet above sea level. Above 2,000 feet, input must be derated 4 percent for each 1,000 feet above sea
level.
2. Standard motors are 115V 60 Hz, single-phase open drip-proof.
3. The flue vent fan motors used on all high efficiency units are 115/60/1; 1/20 hp and 1.5 amps. All other voltages will require an additional
transformer.
4. SPH = Split Phase; CS = Capacitor Start
5. 0.2” maximum external static pressure.
