¹ Natural Gas BTU/h; for altudes above from 0’ to 5,500’ above sea level, reduce input rang 4% for each 1,000’ above 5,500’ altude. Low-re rate is 75% of high-re rate.
² DOE AFUE based upon Isolated Combuson System (ICS)
³ Vent diameter may vary depending upon vent length. Refer to the latest edions of the Naonal Fuel Gas Code NFPA 54/ANSI Z223.1 (in the USA) and the Canada Naonal Standard
of Canada, CAN/CSA B149.1 and CAN/CSA B142.2 (in Canada).
4 Minimum Circuit Ampacity = (1.25 x Circulator Blower Amps) + ID Blower amps. Wire size should be determined in accordance with Naonal Electrical Codes. Extensive wire runs
will require larger wire sizes.
5 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 Connecon ½” FPT
• Important: Size fuses and wires properly and make electrical connecons in accordance with the Naonal Electrical Code and/or all exisng local codes.

Notes
• CFM in chart is without lter(s). Filters do not ship with this furnace, but must be provided by the installer. If the furnace requires two return lters, this chart assumes both lters
are installed.
• All furnaces ship as high-speed cooling and medium-speed heang. Installer must adjust blower cooling and heang speed as needed.
• For most jobs, 400 CFM per ton for cooling is desirable.
• INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLATE.
• This chart is for informaon only. For sasfactory operaon, external stac pressure should not exceed value shown on the rang plate.
• The dashed (----) areas indicate a temperature rise not recommended for this model.
• At higher altudes, a properly derated unit will have approximately the same temperature rise at a parcular CFM, while ESP at the CFM will be lower.
