Bought a Brinkmann Offset Smoker & Grill about a month ago. Used it for smoking babybacks two weeks ago and though the ribs turned out great the firebox got so hot that the paint peeled off the bottom of the firebox and the door assembly. I added the recommended amount of charcoal along with chunks of wood. But I think the coals may of got on the sides and the bottom of the firebox and maybe this caused it to get too hot. Well I took it back to Home Depot and they exchanged it and I plan to use charcoal basket this time. But are there any other modifications that I can use to prevent this from happening again?
