THE PERFORMANCE 80 GAS FURNACE

The 58CTW/58CTY Two-Stage, Variable--speed, 4-way Multipoise Gas Furnaces offer unmatched comfort in their class with ComfortHeatt technology in an 80% AFUE gas furnace. You get the benefits of a ComfortHeatt technology furnace: reduced drafts, reduced sound levels, longer cycles, less temperature swings between cycles, and less temperature differences between rooms. Its exclusive, intelligent microprocessor control adapts to the heating needs of the home by automatically adjusting high and low heat times to maximize comfort. The 58CTW/58CTY furnaces are approved for use with natural or propane gas.

Venting Notes

1. For common vent, vent connector sizing and vent material: United States, latest edition of the National Fuel Gas Code (NFGC), ANSI Z223.1/NFPA 54.

2. Immediately increase to 5-in. (127 mm) vent connector outside furnace casing when 5-in. (127 mm) vent connector required, refer to Note 1.

3. Side outlet vent for upflow and downflow installations must use Type B vent immediately after exiting the furnace, except when Downflow Vent Guard is used in downflow position.

4. Type B vent where required, refer to Note 1.

5. 4--- in. (102 mm) single wall vent must be used inside furnace casing and the Downflow Vent Guard Kit.

6. Accessory Downflow Vent Guard Kit, required in downflow installations with bottom vent configuration.

7. Chimney Adapter Kit required for exterior masonry chimney applications. Refer to Chimney Adapter Kits for sizing and complete application details.

8. Secure vent connector to furnace elbow with (2) corrosion-resistant sheet metal screws, space approximately 180° apart.

9. Secure all other single wall vent connector joints with (3) corrosion-resistant screws spaced approximately 120° apart. Secure Type B vent connectors per vent connector manufacturer’s recommendations.

1. Nominal 350 CFM/ton cooling airflow is delivered with SW1-5 and SW2-2 set to OFF.

Set both SW1-5 and SW2-2 to ON for +7% airflow (nominal 370 CFM/ton). Set SW1-5 to ON and SW2-2 to OFF for +15% airflow (nominal 400 CFM/ton). Set SW2-2 to ON and SW1-5 to OFF for -7% airflow (nominal 325 CFM/ton).

2. Maximum cooling airflow is achieved when switches SW2-6, SW2-7, SW2-8 and SW1-5 are set to ON, and SW2-2 is set to OFF.

3. All heating CFM's are when low heat rise adjustment switch (SW1-3) and comfort/efficiency adjustment switch (SW1-4) are both set to

OFF

4. Ductwork must be sized for high-heating CFM within the operational range of ESP. Operation within the blank areas of the chart is not

recommended because high-heat operation will be above 1.0 ESP.

5. All airflows on 21" casing size furnaces are 5% less on side return only installations.

6. Side returns for 24.5" casing sizes require two sides, or side and bottom, to allow sufficient airflow at the return of the furnace.
