For wedge cases in equipment classes for which a volume metric is used, the MDEC shall be the amount derived from the appropriate standards equation in Table A-4, Table A-5, or Table A-6 of this Article. For wedge cases of equipment classes for which a TDA metric is used, the MDEC for each model shall be the amount derived by incorporating into the standards equation in Table A-4, Table A-5, or Table A-6 of this Article for the appropriate equipment class a value for the TDA that is the product of:

1. The vertical height of the air-curtain (or glass in a transparent door), and

2. The largest overall width of the case, when viewed from the front.

(1) In General. The manufacturer shall equip each gas, oil, and electric hot water boiler (other than a boiler equipped with a tankless domestic water heating coil) with automatic means for adjusting the temperature of the water supplied by the boiler to ensure that an incremental change in inferred heat load produces a corresponding incremental change in the temperature of water supplied.

(2) Single Input Rate. For a boiler that fires at one input rate, the requirements of this subparagraph may be satisfied by providing an automatic means that allows the burner or heating element to fire only when the means has determined that the inferred heat load cannot be met by the residual heat of the water in the system.

(3) No Inferred Heat Load. When there is no inferred heat load with respect to a hot water boiler, the automatic means described in subsections 1605.1(e)(2)(A)1. and 1605.1(e)(2)(A)2. of this Article. shall limit the temperature of the water in the boiler to not more than 140°F.

(4) Operation. A boiler described in subsections 1605.1(e)(2)(A)1. and 1605.1(e)(2)(A)2. of this Article. shall be operable only when the automatic means described in clauses subsections 1605.1(e)(2)(A)1. and 1605.1(e)(2)(A)2., 1605.1(e)(2)(A)3 of this Article is installed.

(B) EXCEPTION to Section 1605.1(e)(2) of this Article: A boiler that is manufactured to operate without any need for electricity or any electric connection, electric gauges, electric pumps, electric wires, or electric devices shall not be required to meet the efficiency standards or design standard that take effect for models manufactured on or after September 1, 2012. Boilers described in this EXCEPTION are required to meet the efficiency standards in effect prior to September 1, 2012, as applicable.
