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– Installer must supply one or two PVC pipes: one for combustion air (optional) and one for the fl ue outlet (required). Vent pipe must be either 2” or 3” in
diameter, depending upon furnace input, number of elbows, length of run and installation (1 or 2 pipes). The optional Combustion Air Pipe is dependent on
installation/code requirements and must be 2” or 3” diameter PVC.
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.
