AHRI recently required that we update the model number of the S9X2 and S9V2 furnaces within the directory. Normally this type of update would duplicate all existing ratings, and would have been invisible to our customers. However, due to new federal regulation requirements, many of the preexisting ratings were changed, or were inadvertently not re-rated, resulting in some missing rating combinations. We are working to correct this issue, and apologize for any inconvenience.
