The low-profile, Quiet-Comfort™ IIS 90 gas furnace offers a 90% efficiency rating, with the comfort of two-stage operation and conventional, multispeed PSC blowers, says the manufacturer. According to the company, the furnace’s two-stage heating contributes to more evenly heated homes, using the quieter first-stage operation 70% to 80% of the time. Suitable for tight spaces, this 40-in., low-profile, multiposition furnace can be installed in upflow, downflow, horizontal-left, or horizontal-right configurations.
