Product Description

This recall involves DuraTech Anchor Plates with Dampers and DuraChimney II Anchor Plates with Dampers. The products are intended for use as a starter section for chimneys in fireplace applications. The dampers allow the chimney to be closed when the fireplace is not in use. Each damper is a short sheet metal vent pipe fitted with a circular damper plate within the vent pipe, and attached to a square anchor plate. The damper plate rotates around an axis rod to control the flow of air through the vent pipe. The damper plates have a weight attached to one side, and a chain attached to the other side. When installed in a fireplace application, the square anchor plate is generally not visible. The DuraTech Anchor Plate with Damper was manufactured in five sizes, as follows: Dura-Vent Product Description Dura-Vent Product Number 10" diameter DuraTech Damper 99142 12" diameter DuraTech Damper 99242 14" diameter DuraTech Damper 99342 16" diameter DuraTech Damper 99442 18" diameter DuraTech Damper 99542 The DuraChimney II Anchor Plate with Damper was manufactured in four sizes, as follows: Dura-Vent Product Description Dura-Vent Product Number 10" diameter DuraChimney Damper 10DCA-APD 12" diameter DuraChimney Damper 12DCA-APD 14" diameter DuraChimney Damper 14DCA-APD 16" diameter DuraChimney Damper 16DCA-APD

Reason for Recall

When the consumer attempts to open/close the damper, it can become stuck in its current position. In addition, some of the dampers were assembled backwards and are set to the closed position when the consumer attempts to open the damper. Both pose risk of carbon monoxide poisoning to the consumer.

Remedy

Consumers should ensure that their damper is in the open position when the fireplace is in use. Consumers or distributors with defective fireplace dampers should contact Dura-Vent to schedule a free repair. The remaining unlocated recalled dampers were distributed in Washington, California, and Colorado. Consumers and distributors whose dampers were previously inspected and repaired do not need to schedule an additional inspection.
