Plain-English summary
Controlled Energy Corporation (CEC) is recalling approximately 320 AquaStar natural gas water heaters, model number AQ38B NG. The heaters were made in Portugal and sold nationwide in the United States through plumbing supply stores and plumbing contractors from March 1997 to January 2001 for about $440, plus installation. The units are off-white with the word "AquaStar" in red on the front, and the model number is located on the rating plate on the right side of the water heater.
The recall is being issued because the heaters can produce dangerous levels of carbon monoxide in the exhaust gas. CPSC and Controlled Energy have received reports of two deaths and two injuries in Manitoba, Canada, reportedly caused by the release of carbon monoxide from the water heater.
Consumers who have the recalled AquaStar unit should turn off the water heater immediately and call Controlled Energy Corporation. CEC is offering consumers a free on-site repair conducted by a licensed professional plumber. Consumers may call Controlled Energy Corporation toll-free at (800) 642-3111 between 8:30 a.m. and 7 p.m. ET Monday through Friday.
