Description

1 Scope

1.1 These requirements cover commercial pollution control unit assemblies that are intended to be installed in line with commercial grease ducts used to exhaust heat, smoke, and grease-laden vapors from commercial cooking operations to the outdoors as specified in the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, NFPA 96, the International Mechanical Code, and the Uniform Mechanical Code.

1.2 These requirements include modular pollution control assemblies, unwelded connections between adjoining parts, fittings, access doors, and the like.

1.3 These requirements do not address NFPA 96 and the International Mechanical Code requirements for pollution control unit fire resistive enclosures. Pollution control units covered only by these requirements are intended to be installed in a fire resistive enclosure when required by NFPA 96 or the IMC.

1.4 Requirements used to evaluate the effectiveness of the combination of a pollution control unit and an enclosure as a fire rated enclosure system and through penetration firestop system, as well as the enclosure's effect on the pollution control unit are contained in Standard for Tests of Fire Resistive Grease Duct Enclosure Assemblies, UL 2221, and ASTM E 2336, Standard Test Methods for Fire Resistive Grease Duct Enclosure Systems.

1.5 This Outline does not measure the efficacy of the pollution control unit to remove grease-laden effluent from the air stream, nor other factors that do not directly affect users or electrical and fire safety.
