¹ Natural Gas BTU/h: for altitudes above 2,000’, reduce input rating 4% for each 1,000’ above sea level. Low-ﬁ re

rate is 75% of high-ﬁ re rate.

² DOE AFUE based upon Isolated Combustion System (ICS).

³ Vent diameter 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 Permanent ﬁ lter size based on 600 FPM. Check with ﬁ lter manufacturer for speciﬁ c details.

5 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.

6 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: It is required to size overcurrent protection device and wires properly and make electrical connections

in accordance with the National Electrical Code and/or all existing local codes.

Notes:

For servicing or cleaning, a 24” front clearance is recommended.

Unit connections (electrical, ﬂ ue, and drain) may necessitate greater clearances than the minimum clearances 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 ﬁ lter(s). Filters do not ship with this furnace, but must be provided by the installer. If the furnace requires two return

ﬁ lters, this chart assumes both ﬁ lters are installed.

For most jobs, about 375 - 400 CFM per ton when cooling is desirable.

INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLATE.

This chart is for information only. For satisfactory operation, external static pressure should not exceed value shown on the rating plate. The

shaded area indicates ranges in excess of recommended maximum heating static pressure.

The above chart is for U.S. furnaces installed at 0-2,000 feet. At higher altitudes, a properly derated unit will have approximately the same

temperature rise at a particular CFM, while ESP at the CFM will be lower.

Factory Motor Speed Setting: T1 = 1st Stage Heating; T2 = 2nd Stage Heating; T5 = Cooling

Temperature rise data is based on 2nd-stage heat. First-stage heat is 75% of rise indicated above.
