Product Data 58YAV Energy-Efficient Upflow Furnace Sizes: 070 thru 155 Advanced Technology for Energy-Efficient Gas Furnaces Carrier leads the industry with its new 58YAV Induced-Draft Gas Furnace. This furnace is built for venting into many exterior tile-lined masonry chimneys. It has the most advanced manufacturing equipment, processes, and technology available in order to ensure top quality. Packed into the cabinet are the industry’s foremost dealer and homeowner features.
The 58YAV Upflow Furnace is the newest addition to Carrier’s list of product leadership in the gas furnace industry. These induced-combustion, gasfired furnaces offer not only low installation costs, but fuel economy as well — delivering an Annual Fuel Utilization Efficiency (AFUE) rating of 78.0 percent. The Carrier 58YAV utilizes a hot surface, silicon carbide ignition system to save energy and increase reliability. Our design uses the patented S-shaped 4-pass heat exchanger, our soft mount inducer assembly, and a slow opening gas valve to improve sound level. The heat exchanger is constructed of aluminized steel and is backed by a 20-year Limited Warranty. The Carrier 58YAV Gas Furnace will meet your home heating requirements. The superior attention to cabinet detail is obvious. This Carrier furnace features 1-piece, seamless, wraparound construction. There are no spot welds on the exterior surfaces of the furnace. There is also double protection for the cabinet. First, a galvanized steel substrate provides resistance to rusting. Then the cabinet is constructed of prepainted steel–the 1998 Carrier Corporation Form No. 58YAV-2PD same high-quality finish found on refrigerators and dishwashers. Perhaps the most advanced feature of the 58YAV is the microprocessor control. The simplified electronics in this control provide high reliability while performing many of the functions of older, electro-mechanical devices in other furnaces. Advanced features of the control show true leadership in furnace technology. The control provides blower delay at start-up and shutdown, while monitoring furnace operations and functions. In the unlikely event of a service call, in less than a minute, the technician can use the self-test feature to determine if a major component has failed. The control will check itself, then the inducer, silicon carbide ignition, heating- and coolingspeed blower, and the electronic air cleaner connections. The control also features a 3-amp fuse that protects the transformer and control. Another feature on the control is an LED status indicator light to ensure top furnace performance. Our induced-combustion furnace has a patented draft safeguard. The draft safeguard will stop furnace operation if the vent system becomes blocked or is not operating properly. Best of all, the Carrier 58YAV is made to be easily installed. Many features make this furnace the easy choice for replacement or new construction markets. Left and right connections are provided for gas and electrical supplies. An easy-to-remove bottom, blower speed selector, cased or uncased cooling coils, low-voltage humidifier, and electronic air cleaner terminal connections are among other features.
