Step 3ÐSupply Air Connections

DOWNFLOW FURNACES

Connect supply-air duct to supply-air opening on furnace. The supply-air duct attachment must ONLY be connected to furnace supply/outlet or air conditioning coil casing (when used), when installed on non-combustible material. When installed on combus- tible material, supply-air duct attachment must ONLY be con- nected to an accessory subbase or factory approved air condition- ing coil casing. DO NOT cut main furnace casing to attach supply side air duct, humidifier, or other accessories. All accessories MUST be connected external to furnace main casing.

HORIZONTAL FURNACES

Connect supply-air duct to supply air opening on furnace. The supply-air duct attachment must ONLY be connected to furnace

supply/outlet or air conditioning coil casing (when used). DO NOT cut main furnace casing to attach supply side air duct, humidifier, or other accessories. All accessories MUST be connected external to furnace main casing.

Step 4ÐReturn Air Connections

Do not install the furnace on its back or sides. Safety control operation will be adversely affected. Never connect return-air ducts to the back of the furnace. A failure to follow this warning can cause a fire, personal injury, or death.

The return-air duct must be connected to return-air opening provided as shown in Fig. 1. DO NOT cut into casing sides or back

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.
