ACTION: Request for information.
AGENCY:

The U.S. Department of Energy DOE is undertaking an early assessment review to determine whether amendments are warranted for the test procedure for consumer furnace fans.
DOE has identified certain issues associated with the currently applicable test procedure on which DOE is interested in receiving comment. The issues outlined in this document mainly concern: Test settings selection of airflow control settings and external static pressure ESP requirement for airflow settings other than the maximum setting; incorporation by reference of the most recent industry test method; clarifications for testing of certain products, including furnace fans with modulating controls, furnace fans and modular blowers tested with electric heat kits, certain two-stage furnaces that operate at reduced input only for a preset period of time, dualfuel furnaces, and certain oil-fired furnaces; and issues related to test procedure repeatability and reproducibility. DOE welcomes written comments from the public on any subject within the scope of this document, including topics not raised in this request for information RFI.

I. Introduction DOE established an early assessment review process to conduct a more focused analysis that would allow DOE
to determine, based on statutory criteria, whether an amended test procedure is warranted. 10 CFR part 430, subpart C, appendix A, section 8a. This RFI
requests information and data regarding whether an amended test procedure would more accurately and fully comply with the requirement that the test procedure produce results that measure energy use during a representative average use cycle for the product, and not be unduly burdensome
