Question about RTO W4 A.O Smith Gas Hot Water Heater Draft Inducer
The Cold air screen on the bottom of the water heater is partially plugged. That is if the pilot light can be lit and stay on, but goes out when the heater should be functioning normally. This is not the removable plastic screen but a round white-yellow grid with 1/32" holes. You can try to clean it through the bottom but you may have to remove the gas line from the controller to the burner, pilot gas line, and thermocouple connection to remove that complete assembly to get access to the screen. The AO Smith booklet warns of this but they pretend the plastic screen will keep this second screen clean but it won't. After three years it was two thirds plugged.

SOURCE: gas pilot wont stay on
they are universal, the only thing youi need to know is how long it should be, most will take a 30inch, just to make sure you have enough, our oyu can take the one out that you have and match it up, the one you take out will actually measure a little shorter then the new one which is ok, just make sure you put the burner assembly back in the perch correctly, if not you will have bigger problems then you want to have
