§ 431.87 Energy conservation standards and their effective dates.
(a) Each commercial packaged boiler manufactured on or after January 1, 1994, and before March 2, 2012, must meet the following energy efficiency standard levels:
(1) For a gas-fired packaged boiler with a capacity (rated maximum input) of 300,000 Btu/h or more, the combustion efficiency at the maximum rated capacity must be not less than 80 percent.
(2) For an oil-fired packaged boiler with a capacity (rated maximum input) of 300,000 Btu/h or more, the combustion efficiency at the maximum rated capacity must be not less than 83 percent.
(b) Each commercial packaged boiler listed in Table 1 to § 431.87 and manufactured on or after the effective date listed in Table 1 of this section, must meet the applicable energy conservation standard in Table 1.

      Final rule.
      The effective date of this rule is July 13, 2015. Compliance will be mandatory starting one year after the publication in the Federal Register of a mathematical conversion factor to convert from the existing efficiency ratings to efficiency ratings under the test procedure adopted by this final rule, or December 31, 2015, whichever is later. The incorporation by reference of certain publications listed in this rule is approved by the Director of the Federal Register as of July 13, 2015. Other publications referenced were approved on March 23, 2009, and May 16, 2012.
