NOTE: For high altitude conversion, an orifice change may also be required. See Form 035-14447-001 for application information.
Annual Fuel Utilization Efficiency (AFUE) numbers are determined in accordance with DOE Test procedures.
Wire size and over current protection must comply with the National Electrical Code (NFPA-70-latest edition) and all local codes.
The furnace shall be installed so that the electrical components are protected from water.
* ESP (External Static Pressure) .5" WG is at furnace outlet ahead of cooling coil.
NOTES:
1. All filters must be high velocity cleanable type.
2. Air flows above 1800 CFM require either return from two sides or one side plus bottom.
