Grease Ducts


AMPCO – All pipe models are UL 1978 grease duct rated to their relative clearance to combustibles (single-wall, double-wall air or blanket insulated). Zero Clearance grease duct models Z3 & Z4 are additionally UL 2221 rated to zero clearance to combustibles and have an integral 2 hour fire rated enclosure, not requiring a separate fire rated shaft. Alternatively, the Z3 can be used for other hourly rated integral shaft needs. Just call to inquire.
