SAFETY CONSIDERATIONS

Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified person- nel should install, repair, or service heating equipment.

Untrained personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be performed by trained service personnel. When working on heating equipment, observe precautions in the literature, on tags, and on labels attached to or shipped with the unit and other safety precautions that may apply.

In the United States, follow all safety codes including the National Fuel Gas Code (NFGC) NFPA 54-1996/ANSI Z223.1-1996 and the Installation Standards, Warm Air Heating and Air Condition- ing Systems (NFPA 90B) ANSI/NFPA 90B.

In Canada, refer to the CAN/CGA-B149.1- and .2-M95 National Standard of Canada, Natural Gas and Propane Installation Codes (NSCNGPIC).

Wear safety glasses and work gloves. Have fire extinguisher available during start-up and adjustment procedures and service calls.

Recognize safety information. This is the safety-alert symbol . When you see this symbol on the furnace and in instructions or manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, CAUTION, and NOTE. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard which could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances, these instructions exceed certain local codes and ordinances, especially those that may not have kept up with changing residen- tial construction practices. We require these instructions as a minimum for a safe installation.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

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.
