It's got the grates that lift up to add fuel.
The guy actually was using his to smoke with and bought a new smoker.
I'm just gunna clean it, season it and probably add a thermometer. And den we gunna smoke
nice pick up i hope you didnt pay over 80-100$ wally world sells them 100 brand new... Also if thats going to be used alot as a smoker might want to consider ordering a smokeanator or a vortex for your kettle they look like handy tools but i dont know for sure. i mainly use my kettle for grilling but i may get a wild hair and throw some ribs or maybe a brisket on there soon.
a charcoal chimney or 2 full of coals would likely be sufficient for cleaning it but you could also use white vinegar and spray it around and do it a bit of scrubbing. just make sure you do a dry run before cook food on it the vinegar could impart a nasty flavor. as for using bricks in the grill yes red would work but pretty much any brick or rock would work it would not only keep the coals in place but act as a diffuser to keep the direct heat off the meat which with smoking low n slow is what you want.
