Navien Inc., of Irvine, Calif., is recalling about 3,400 Navien 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.
No incidents or injuries have been reported.
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.
