In the coming weeks, changes will be made within our existing S9X2 model family. This family will be upgraded to a 9-tap constant torque ECM blower motor and will also include a new heat exchanger design that reduces noise levels in liquid propane (LP) and natural gas applications. With these changes, 4 additional models now reach 96% AFUE! Only one model saw a reduction from 96% to 95% AFUE.
