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
58CTA/CTX
individual “zones” of the home.
This is accomplished through a
series of electronic dampers and
remote room sensors. The 4-zone
system is shown.

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.
