Low-fire rate is 75% of high-fire rate. ² DOE AFUE based upon Isolated ombustion System (IS) ³ Vent diameter may vary depending upon vent length. Refer to the latest editions of the National Fuel Gas ode NFPA 54/ANSI Z223.1 (in the USA) and the anada National Standard of anada, AN/SA B149.1 and AN/SA B142.2 (in anada). 4 Minimum ircuit Ampacity = (1.25 x irculator Blower Amps) + ID Blower amps. Wire size should be determined in accordance with National Electrical odes. Extensive wire runs will require larger wire sizes. 5 Refers to maximum recommended fuse or circuit breaker size. May use fuses or HAR-type circuit breakers of the same size as noted. Notes All furnaces are manufactured for use on 115 VA, 60 Hz, single-phase electrical supply.

Filters do not ship with this furnace, but must be provided by the installer. If the furnace requires two return filters, this chart assumes both filters are installed. All furnaces ship as high-speed cooling and medium-speed heating. Installer must adjust blower cooling and heating speed as needed. For most jobs, 400 FM per ton for cooling is desirable. INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPEIFIED ON THE RATING PLATE. This chart is for information only. For satisfactory operation, external static pressure should not exceed value shown on the rating plate. The dashed (----) areas indicate a temperature rise not recommended for this model. At higher altitudes, a properly derated unit will have approximately the same temperature rise at a particular FM, while ESP at the FM will be lower. SS- 5
