Hello all, I recently found an old smoker that was my grandfathers who has since passed away. I am unsure about how this thing works, or what is needed to operate it. The smoker is a Masterbuilt 7-1 Hitch-Haul which I'm sure is about 20 years old. I have a couple of questions about the equipment. 1. Do I place the wood chunks directly above the heating element (see photo 1)? 2. The water bowl has a hole in the bottom from corrosion, is the water bowl necessary for the operation of the smoker? Any input or advice will be appreciated, I have no experience using a smoker. Thank you in advance!
