Have any of you changed out the temp control dial? It has a thermostat wire that screws into the HX. Question is.......does it screw into a dry well, or directly into the HX water flow? It has the temp bulb, with a brass washer on the top, and a brass screw-in retainer nut. What type of seal does this use? I have an extra, but it doesn't have a seal or packing. I want to change it out tomorrow, but don't want to tear into it before knowing what I need to seal this connection.
