Product Recalls

A. O. Smith Recalls Ultra-Low NOx Water Heaters Due to Fire Hazard

Hazard:

The water heater’s gas burner screen develops tears. The water heater’s burner can then create excess radiant heat, posing a fire hazard if the water heater is installed directly on a wood or other combustible floor.
