¹ Natural Gas BTU/h; for altitudes above from 0’ to 4,500’ above sea level, reduce input rating 4% for each 1,000’ above 4,500’ altitude. Low-fire rate is 70% of high-fire rate.

² DOE AFUE based upon Isolated Combustion System (ICS).

³ Minimum Circuit Ampacity = (1.25 × Circulator Blower Amps) + ID Blower amps. Wire size should be determined in accordance with National Electrical Codes. Extensive wire runs will require larger wire sizes.

⁴ Maximum Overcurrent Protection Device refers to maximum recommended fuse or circuit breaker size. May use fuses or HACR-type circuit breakers of the same size as noted.

Notes:

• All furnaces are manufactured for use on 115 VAC, 60 Hz, single-phase electrical supply
• Gas Service Connection ½” FPT
• Important: Size fuses and wires properly and make electrical connections in accordance with the National Electrical Code and/or all existing local codes.
