Table 8. Correction factors for high altitude installations
Altitude Above Sea Level (ft) 0 2,000 3,000 4,000 5,000 6,000 7,000
Gas Heating Capacity 1.00 0.92 0.88 0.84 0.8 0.76 0.72
Fan rpm 1.00 1.04 1.06 1.09 1.12 1.15 1.19
Fan bhp 1.00 1.07 1.12 1.18 1.25 1.33 1.41
Notes:
1. For high altitude installations above 2,000 feet, reduce ratings 4 percent for each 1,000 feet above sea level.
2. Multiply standard unit by correction factor to get actual input and required rpm and hp.

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. CS = Capacitor Start; SPH = Split Capacitor
3. Standard motors are 115/60/1 open drip-proof.
4. 0.2 maximum external static pressure.
5. Unit amps are based on hot surface pilot ignition.
