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. DOE AFUE based upon Isolated Combustion System (ICS) Minimum Circuit Ampacity = (1.25 x 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. 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 FPT Important: Size fuses and wires properly and make electrical connections in accordance with the National Electrical Code and/or all
existing local codes.

C = If placed on combustible floor, the floor MUST be wood ONLY.
Notes: For servicing or cleaning, a 24 front clearance is recommended. Unit connections (electrical, flue, and drain) may necessitate greater clearances than the minimum clearances listed above. In all cases, accessibility clearance must take precedence over clearances from the enclosure where accessibility clearances are greater. Refer to the appropriate USA and Canadian codes:
In the USA: the National Fuel Gas Code NFPA 54 / ANSI Z223.1 In Canada: the Canada National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B142.2

All furnaces ship as high speed for cooling. Installer must adjust blower speed as needed. For most jobs, about 400 CFM per ton when cooling is desirable. Do not operate above .5 w.c. ESP in heating mode. Operating CFM between .5 and .8 w.c. is tabulated for cooling purposes only.
