The American Standard 92 is a single-stage gas furnace with an efficiency rating of 92.1% AFUE. The unit features an aluminized steel primary heat exchanger which is crimped instead of welded to prevent cracks, and a stainless steel secondary heat exchanger. A hot-surface igniter provides efficient, reliable operation, and multi-port in-shot burners improve efficiency by maximizing heating while using less fuel. It has a multi-speed blower motor which improves comfort while reducing noise levels, and a heavy steel insulated cabinet which is designed to reduce operating noise levels and heat loss.
