to attach any portion of return-air duct. Bypass humidifier connec- tions should be made at ductwork or coil casing sides exterior to furnace.

Step 5ÐDownflow Installation

NOTE: This furnace is approved for use on combustible materials or wood flooring. A factory accessory floor base, as listed on the furnace rating plate, MUST be used. A factory accessory floor base is not required when this furnace is installed on manufactur- er's Coil Assembly Part No. CD5 or CK5, or Coil Box Part No. KCAKC is used.

1.Determine application being installed from Table 3.

2.Construct hole in floor per dimensions specified in Table 3 and Fig. 5.

3.Construct plenum to dimensions specified in Table 3.

4.If downflow subbase (KGASB) is used, install as shown in Fig. 6.

If coil assembly CD5, CK5, or Coil Box KCAKC is used, install as shown in Fig. 7.

Step 6ÐHorizontal Attic Installation

Do not install the furnace on its back; safety control operation will be adversely affected. Never connect return-air ducts to the sides or back of the furnace. Failure to follow this warning could result in fire, personal injury, or death.

The furnace can be installed horizontally on either the left-hand (LH) or right-hand (RH) side. A typical attic installation is shown in Fig. 8.

CONSTRUCT A WORKING PLATFORM

Construct working platform on location where all required furnace clearances are met. (See Fig. 2 and 8.)

58ZAV specifications

The Carrier 58ZAV is a high-efficiency gas furnace that exemplifies Carrier's commitment to innovation and performance in residential heating solutions. Designed to provide optimal comfort, the 58ZAV boasts a range of features that cater to the needs of homeowners seeking reliable and energy-efficient heating systems.

One of the standout characteristics of the Carrier 58ZAV is its impressive Annual Fuel Utilization Efficiency (AFUE) rating, which often exceeds 95%. This high AFUE ratio means that the furnace converts a significant portion of its fuel into heat, ensuring minimal energy waste and lower utility bills. This efficiency aligns with modern energy standards and reflects Carrier's dedication to environmentally conscious engineering.

The 58ZAV employs a two-stage heating process, which allows for better temperature control and more consistent comfort levels throughout the home. The furnace operates on low capacity for most of the heating cycle, ensuring that it does not overheat the living spaces. When a quick boost of heat is needed, it can switch to high capacity, providing the necessary warmth efficiently.

Additionally, this gas furnace features a variable-speed blower motor. This motor adapts its speed according to the heating demand, delivering more even airflow and maintaining consistent humidity levels within the home. This adaptability not only enhances comfort but also contributes to a quieter operation, minimizing disruptive noise levels typically associated with traditional furnaces.

Incorporating advanced technology, the Carrier 58ZAV is compatible with smart thermostats and can be integrated into a home automation system. This feature allows homeowners to monitor and control their heating system remotely, optimizing energy usage and comfort from anywhere.

The furnace is designed with durability in mind, featuring a corrosion-resistant heat exchanger and other robust components that ensure long-lasting performance. Moreover, Carrier offers a range of warranties, providing peace of mind to homeowners investing in this heating solution.

Overall, the Carrier 58ZAV is a top-of-the-line gas furnace that combines efficiency, advanced technology, and comfort. With its high AFUE rating, two-stage heating process, variable-speed blower motor, and compatibility with smart home systems, it represents a modern heating solution that meets the demands of today's environmentally aware consumers. Whether for new installations or replacements, the 58ZAV stands out as a reliable choice for residential heating needs.
