OK so a neighbor gave me an old smoker that was sitting around in his side yard. this is great news since i was ruining my dads grill trying to smoke meats in it. i am now the proud new owner of a Char-Broil Smoker h2o electric. i have some questions that hopefully you guys can answer. wondering also if i have everything this originally went with this. OK first question is about the thermometer. this one needs to be replaced and I'm wondering what the best way to do that is. this is the inside of the thermometer i dint know how to take that out without doing damage. the second is there is no vent on the top for smoke to release. should i put one in? and there is also this... I'm worried about that gap there. should i be? any information on this guy would be helpful as far as refurbishing it and how to use it.
