Navien in conjunction with the U.S. Consumer Products Safety Commission has issued a recall for certain of the company's condensing tankless water heaters and combination boilers. A kit installed on the tankless water heaters and boilers to convert them from natural gas to propane can cause the unit to produce excessive amounts of carbon monoxide, posing a risk of carbon monoxide poisoning to consumers.
This recall involves only Navien condensing tankless water heaters and combination boilers with model numbers NPE-180A, NPE-180S and NCB-180E that have been or will be converted from using natural gas to propane gas. The recalled water heaters and combination boilers were manufactured between July 9, 2018 through October 14, 2018. The manufacturing date is identified within the serial number. The serial number is printed on a label which is affixed to the side of the unit and on the product packaging. The first two digits identify the year, the next single digit identifies the month, and the last two digits identify the day. (For example, 18709 stands for July 9, 2018. X stands for October.) The recall affects about 3,400 units.
Consumers should immediately stop using the recalled water heaters and boilers that are using propane gas and contact Navien for a free replacement conversion kit. Consumers who continue use of the water heaters and boilers while awaiting repair, should have a working carbon monoxide alarm installed outside of sleeping areas in the home.
The U.S. Consumer Product Safety Commission is charged with protecting the public from unreasonable risks of injury or death associated with the use of thousands of types of consumer products under the agency’s jurisdiction. Deaths, injuries, and property damage from consumer product incidents cost the nation more than $1 trillion annually. Visit the CPSC web site at https://cpsc.gov.
