To properly define and distinguish between decorative hearth products and vented hearth heaters.

Amends the Energy Policy and Conservation Act to exempt decorative hearth products from consideration as direct heating equipment subject to the Act's energy efficiency standards.

Defines a "decorative hearth product" as a vented gas fireplace, stove, gas fireplace insert, or gas log set that: (1) is not certified to the ANSI Z21.88 standard and, in the case of vented gas fireplaces, fireplace inserts, or stoves, is certified to the ANSI Z21.50 standard; (2) is sold without a thermostat and with a warranty provision expressly voiding manufacturer warranties in the event the product is used with a thermostat; and (3) contains no energy efficiency representations other than P.4 efficiencies required for products sold in Canada.

Adds the product category "vented hearth heater," defined as a vented gas fireplace, fireplace insert, or stove: (1) for which any AFUE (annual fuel utilization efficiency) representation, or representation with respect to P.4 efficiencies required for products sold in Canada, is made in any manufacturer advertising or literature; (2) certified to the ANSI Z21.88 standard or identified in any manufacturer literature or advertising as a "heater-rated" product; or (3) equipped by the manufacturer with a thermostatic control.

Deems a vented gas fireplace, fireplace insert, stove, or gas log set that is not a decorative hearth product to be direct heating equipment for purposes of the Act.
