Ultra-Low NOx Water Heater Recall

Brands being recalled include American Water Heater, A.O. Smith, Kenmore, Lochinvar, State, Reliance, U.S. Craftmaster, Whirlpool. Most of the affected water heaters were sold and installed in California between April, 2011 and December, 2016 to meet strict emission standards.

According to the CPSC’s release, the Ultra-Low NOx water heater’s burner screen may develop tears. If this happens, the water heater’s burner can develop excess radiant heat. If the water heater stands directly on a wood floor (or similar combustible material), this poses a fire hazard. A.O. Smith has received 6 reports of fires occurring from this issue. No injuries have been reported to date.
