A: I am sorry I can’t answer that definitively. I would need and I would refer you to the specific parts breakdown for your heater based on its specific model and serial number. I say that because AO Smith and other water heater companies may produce the same model for years but depending on when it was made the design may have changed. So, you need the parts break down that refers to your serial number. If you don’t have this check AO Smiths web site or give them a call. Have the complete Model and Serial number available as you will need it. It can be found on the heaters rating plate.
A: I am sorry I can’t give you a definitive answer as I am not in possession of your heater’s parts breakdown. A O Smith does not produce igniters, they source them from different producers. Therefore, depending on when your unit was produced it could have a different ignition system. You first want to identify the A O Smith part number for the igniter you need. There should be a part breakdown I your installation manual. If you do not have that you can contact A O Smith. Have the complete model and serial number handy. They can be found on the units rating plate. Based on that information the people at Smith should be able to tell you the part number for the igniter used on your specific version of that model. Once you have the A O Smith part number you can see if that is one of the part numbers that this unit replaces. If you scroll down the Home Depot product listing page you fill find a section entitled Product Details. If you expand that section you will find PDFs of the product documents which include part number cross references.
A: I do not think so. From informaion on A.O Smiths web site that model does not utilize a hot surface igniter. Instead it has a standing pilot. It appears to have a pieze igniter to light the pilot durring installation. But it does not appear to have a powered intermitent ignition system. In fact the unit does not appeart to utilize a electric power supply. Although I am not an experpert on A.O Smith, so you would want to comfirm in your owners manual, I would assume this unit utilizes a thermal couple not a hot surfase igniter.
A: Yes it will
