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 115/60/1 open drip-proof motor.
3. Thermal efficiency for the 003 and 004 units are based on stack in horizontal position.
4. The flue vent fan motors used on all high efficiency units are 115/60/1; 1/20 hp and 1.5 amps.

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.

Notes:
1. For high altitude installations above 2,000’, reduce ratings 4% for each 1,000’ above sea level.
2. Multiply standard unit by correction factor to get actual input and required rpm and hp.
