Installer must supply one or two 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 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 Electric 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 1/2" FPT
Important: Size fuses and wires properly and make electrical connections in accordance with the National
Electrical Code and/or all existing local codes.
For bottom return: Failure to unfold flanges may reduce airflow by up to 18%. This could result in performance
and noise issues.
For servicing or cleaning, a 24" front clearance is required. Unit connections (electrical, flue and drain) may
necessitate greater clearances than minimum clearances listed above. In all cases, accessibility clearance must
take precedence over clearances from the enclosure where accessibility clearances are greater.
