ABSTRACT:
An access door (10) for cleaning grease from duct runs (26) in exhaust systems for kitchen cooking equipment (16). The access door (10) includes a collar (32) which is mounted at a selected location in a run of duct to provide an opening (46) for accessing the interior surfaces (30) of the duct. A fireproof cover (54) is releasably secured to the collar (32) by securing devices for selectively closing the collar opening. A seal (70) is interposed between the collar the cover, proximate the juxtaposed portions to prevent fire from escaping the duct through the collar opening when the cover is mounted thereon.
