Nomenclature

¹ Natural Gas BTU/h
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 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 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.
• 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 the minimum learances listed above. In all cases, accessibility clearance must take precedence over clearances from the enclosure where accessibility clearances are greater.

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 heating. Installer must adjust blower cooling and heating speed as needed.

NOTES:

1. SET HEAT ANTICIPATOR ON ROOM THERMOSTAT AT 0.7 AMPS.
2. MANUFACTURER’S SPECIFIED REPLACEMENT PARTS MUST BE USED WHEN SERVICING.
3. IF ANY OF THE ORIGINAL WIRE AS SUPPLIED WITH THE FURNACE MUST BE REPLACED IT MUST BE REPLACED WITH WIRING MATERIAL HAVING A TEMPERATURE RATING OF AT LEAST 105v C. USE COPPER CONDUCTORS ONLY.
4. UNIT MUST BE PERMANENTLY GROUNDED AND CONFORM TO N.E.C. AND LOCAL CODES.
5. TO RECALL THE LAST 6 FAULTS, MOST RECENT TO LEAST RECENT, DEPRESS SWITCH FOR MORE THAN 2 SECONDS WHILE IN STANDBY (NO THERMOSTAT INPUTS)
