"Protecting "some" has caused me HUGE problems"
Having rental property, I have purchased about 6 of these water heaters in the past 5 years. When they are first installed, they work great but due to the design of the "flame arrestor" and the "air intake screen" it is not long before the flame will not stay lit in the Natural Gas Models. I sent away for the special attachment that is supposed to fit on to a vacuum cleaner to clean the flame arrestor, but it did not work. I have spoken to my plumber, people that work for the company I bought it from and representatives of a o Smith and not much has changed in the design of these units and I continue to have constant problems at my home and at the rental properties with the flame not staying lit. I understand that this design was what they came up with after politicians required changes to protect people from themselves after people were injured or killed doing things like using cleaning solvents near the open flame of the old style units. I don't know what regulations or laws were put into place, but I do know that these units do not function properly or dependably as heaters of water under normal conditions.
