Upon arrival called Bradford white customer service and let the support tech know that the water heater is lighting up every two minutes and that i smell gas coming from the control valve. Bradford white tech support said there might be soot in the burner. Next replaced diaphragm and pilot assembly. Also cleaned out soot in burner area. Upon replacing diaphragm also installed gas drip leg at control valve. Turned gas back on and pilot light right up. Then went to kitchen sink ran hot water to make sure the burner will light back up and it did.
