Hello... I just bought a Master Forge propane smoker. I seasoned it last night and have my first batch of ribs in there now. My problem? There's hardly any smoke coming out of the chimney. The side vents are almost all the way closed and the chimney is wide open. but, I just don't see a lot of smoke. I soaked my wood chips for about 3 hours...What am I doing wrong? Thanks in advance!!
