Hey smarter guys than me... I'm trying to figure out what exactly needs to happen here. I have a high pressure (2lb) service to my house with a dual outlet box in my patio. I want to convert my new LP smoker to Natural Gas so I don't need to worry about running out of Propane. Based on the pressure and the two 10000 btu burners my internet searches have landed me around a 15/64" drill bit for the orifice. New hose and that's it? I've seen the kits that come with new knob controls is that necessary?
