¹ Natural Gas BTU/h
² DOE AFUE based upon Isolated Combustion System (ICS)
Note s
• All furnaces are manufactured for use on 115 VAC, 60 Hz, single-phase electrical supply.
• Gas Service Connection ½" FPT
• For bottom return: Failure to unfold flanges may reduce airflow by up to 18%. This could result in performance and noise issues.
³ Installer must supply one or tw o PVC pipes: one for combustion air (optional) and one for the flue outlet (required). Vent pipe must be either
2" or 3" in diameter, depending upon furnace input, number of elbow s, 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.
?
Minimum Circuit Ampacity = (1.25 x Circulator Blow er Amps) + ID Blow er amps. Wire size should be determined in accordance w ith
National Electrical Codes. Extensive w ire runs w ill require larger w ire sizes.
?
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.
• Important: Size fuses and w ires properly and make electrical connection in accordance w ith the National Electrical Code and/or all existing
local codes.
• For servicing or cleaning, a 24" front clearance is required. Unit connections (electrical, flue and drain) may necessitate greater clearances
than the minimum clearances listed above. In all cases, accessibility clearance must take precedencee over clearances from the enclosure
w here accessibility clearances are greater.
