Effikal Recalls Gas Vent Dampers Due to Carbon Monoxide Hazard

Effikal LLC, of Orion, Mich., in cooperation with the U.S. Consumer Product Safety Commission, has announced a voluntary recall of its Automatic Gas Vent Dampers.

The automatic gas vent damper could fail, and if the blocked vent switch does not activate, the vent could leak carbon monoxide (CO), posing a risk of CO poisoning to consumers. No incidents or injuries have been reported.

The dampers were manufactured in the United States and were sold by plumbing and heating wholesale distributors to plumbers and contractors nationwide from August 2007 through July 2008 for between $1,000 and $4,000 for the boilers. Gas vent dampers were sold as part of the gas boiler systems.

The recall involves approximately 45,000 Effikal RVGP-PC Gas Vent Damper size 4, 5, 6, 7, 8, 9, or 10 which are installed with the gas boiler systems listed below. The vent damper date code is located on a sticker under the motor assembly cap on the plastic base. Serial numbers are located on a label on the side of the damper's cap. All sizes and models of the RVGP-PC have the same motor assembly with black Effikal caps and black plastic bases.
