  standards that are currently incorporated by reference. DOE is also establishing a new metric, 
Thermal Efficiency Two (TE2), and corresponding test proced ure. Use of the newly established test 
procedure would become mandatory at such time as compliance with amended energy conservation 
standards based on TE2 is required, should DOE adopt such standards. DOE also is adopting 
additional specifications for CWAF s with multiple flue outlets or small flue outlets.  
DATES: The effective date of this rule is 3 July 2023. These amendments will be mandatory for 
CWAF equipment testing starting 28 May 2024. The incorporation by reference of certain material 
listed in this  rule is approved by the Director of the Federal Register on 3 July 2023.
