1 Natural Gas BTU/h. For altitudes above 2,000', reduce input rating 4% for each 1,000' above sea level.
2 DOE AFUE based upon Isolated Combustion System (ICS)
3 Vent and combustion air diameters may vary depending upon vent length.
Refer to the latest editions of the National Fuel Gas Code NFPA 54/ANSI Z223.1 (in the USA) and the Canada National 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 National Electrical Codes.
Extensive wire runs will require larger wire sizes.
5 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.
NOTES:
* These furnaces are manufactured for natural gas operation. Optional Kits are available for conversion to propane gas operation.
* For elevations above 2000 ft. the rating should be reduced by 4% for each 1000 ft. above sea level. The furnace must not be derated, orifice changes should only
be made if necessary for altitude.
* The total heat loss from the structure as expressed in TOTAL BTU/HR must be calculated by the manufactures method in accordance with the "A.S.H.R.A.E.
GUIDE" or "MANUAL J-LOAD CALCULATIONS" published by the AIR CONDITIONING CONTRACTORS OF AMERICA. The total heat loss calculated should be
equal to or less than the heating capacity. Output based on D.O.E. test procedures, steady state efficiency times output.
Unit specifications are subject to change without notice. ALWAYS refer to the unit's serial plate for the most up-to-date general and electrical information.
