Hi all, new to the site. I am a novice and just got a Brinkmann Vertical/Rectangle Smoker with the top and bottom doors. I have followed the instructions regarding curing it and used brickets. While I was doing that I could not get the temp any higher them 150 degree's. Today I thouhght I would try again before I actually smoked anything and used hardwood charcoal and was able to get the temp up to 200 degree's for a while. What do I have to do to get to to 200 to 250 and maintain that heat?? Help
