THE PERFORMANCE 80 GAS FURNACE
The 58CTA/CTX Two-Stage, 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
ComfortHeatttechnology 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 58CTA/CTX furnaces are approved for use
with natural or propane gas, and the 58CTX is approved for use in
Low NOx Air Quality Management Districts.

AND ZONING
Available in programmable and
non-programmable models, Carrier
thermostats maintain a constant
temperature level in the home.
For the ultimate in home comfort,
Carrier’s 2, 4, and 8-zone systems
allow temperature control of
individual “zones” of the home.
This is accomplished through a
series of electronic dampers and
remote room sensors. The 4-zone
system is shown.

MODEL HUMCCLFP
HUMIDIFIER
By adding moisture to winter-dry
air, a Carrier humidifier can often
improve comfort and keep
furniture, rugs, and draperies in
better condition. Moisturizing
household air also helps to retain
normal body heat and provides
comfort at lower temperatures.

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.

NOTES:
1. Two additional 7/8 ---in. (22 mm) diameter holes are located in the top plate.
2. Minimum return---air openings at furnace, based on metal duct. If flex duct is used, see flex duct manufacturer’s recommendations for equivalent diameters.
a. For 800 CFM---16---in. (406 mm) round or 14 1/2 x 12---in. (368 x 305 mm) rectangle.
b. For 1200 CFM---20---in. (508 mm) round or 14 1/2 x 19 1/2---in. (368 x 495 mm) rectangle.
c. For 1600 CFM---22---in. (559 mm) round or 14 1/2 x 22 1/16---in. (368 x 560mm) rectangle.
d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data literature for specific use of single side inlets. The use of both sideinlets,
a combination of 1 side and the bottom, or the bottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.
