Comes off a Rheem 40 gal natural gas powervent 2 water heater.
Was a replacement for 4 years tops and salvaged the assy, so lots life left yet. Bring your electrical tester to verify if you desire.
Don't ask me to cross reference please as I know what this was on and you need to be aware of proper fitment for your protection. No returns that's why if you need to test for yourself I guarantee the unit to work upon your testing good. Or buy at will
