Recognizing the fact that the heat exchanger is the most crucial component of the gas furnace, Amana's stainless steel heat exchangers are made using:

409 Stainless Steel

  • Proven durability and safety
  • Offers maximum thermal characteristics
  • Provides maximum corrosion resistance

Tubular Design

  • A patented process that far surpasses the efficiency and durability of other heat exchanger designs
  • Offers superior mechanical properties
  • Effective design
  • Efficient design

Wrinkle Bend Process

  • Wrinkle bend process is a manufacturing process that originated at Amana in 1988 to maximize the strength of the heat exchanger
  • Reinforced tubing at all bends
  • Improved efficiency

Dual Diameter Tubing

  • A proven method of achieving the greatest efficiency per square inch of every heat exchanger

Leak Resistant Muffler Joint

  • Automatic process joins the two tubes together and then provides pressure at approximately 2,000 pounds of hydraulic pressure (16,000 psi) to form a tight, leak-resistant seal
