DOE AFUE based upon Isolated Combusꢀon System (ICS).
Vent diameter may vary depending upon vent length. Refer to the latest ediꢀons of the Naꢀonal Fuel Gas Code NFPA
54/ANSI Z223.1 (in the USA) and the Canada Naꢀonal Standard of Canada, CAN/CSA B149.1 and CAN/CSA B142.2 (in
Canada).

Minimum Circuit Ampacity = (1.25 x Circulator Blower Amps) + ID Blower amps. Wire size should be determined in ac-
cordance with Naꢀonal Electrical Codes. Extensive wire runs will require larger wire sizes.
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.

Important: It is required to size overcurrent protecꢀon device and wires properly and make electrical connecꢀons in ac-
cordance with the Naꢀonal Electrical Code and/or all exisꢀng local codes.

For servicing or cleaning, a 24” front clearance is recommended.
Unit connecꢀons (electrical, ꢁue, 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:

Notes
•
CFM in chart is without filter(s). 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 heaꢀng. Installer must adjust blower cooling and heaꢀng speed as needed.
For most jobs, about 375 - 400 CFM per ton when cooling is desirable.
INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLATE.
This chart is for informaꢀon only. For saꢀsfactory operaꢀon, external staꢀc pressure should not exceed value shown on the raꢀng plate.
The above chart is for U.S. furnaces installed at 0-2000 feet. At higher alꢀtudes, a properly derated unit will have approximately the same
temperature rise at a parꢀcular CFM, while ESP at the CFM will be lower.
•
•
Factory Motor Speed Seꢂng: T1 = 1st Stage Ht, T2 = 2nd Stage Ht, T5 = Cooling
Tempertaure rise data is based on 2nd-stage heat. First-stage heat is 75% of rise indicated above.
