    I've been using this smoker for about 5 or 6 months and really like it.  But I just ran into an issue.  I tried calling customer service, but that was a complete waste of time.

    Here is my issue and I'd appreciate any advice or help.

    The last time I tried to smoke some pork loin, I got everything going, but the metal nozzle that hooks into the burner, it has a few holes in it for excess propane to escape (at least I imagine.)  Well that area is igniting on me.  I know all the propane isn't getting to the burner, the burner is igniting, but is a yellowish flame.  I don't know if I have a clog somewhere, or if my nozzle that hooks into the burner is bent a little was bent a little when I got the thing, but it's never done this before.

    Thanks for your help.

    The metal nozzle is the venturi tube and the holes are not for excess propane but the draw air in for a proper fuel mixture.

    I had a yellow flame problem - cleaning the venturi tube fixed it. Try it. Just be careful when doing it-use a flexible brush.

    Atomicsmoke is correct. The holes are for drawing in air. and they commonly have an adjustable shutter for tuning tha air amount. So remove the burner tube and run a brush up through the center. A soft brass or stif nylon. You can use a gun cleaning rod for a small caliber or a bristle brush for a coffee pot stem. Fuzz or a spider web inside. If you have to remove the air shutter to access the end make sure and put a reference mark for re-assembly. That way you do not have to reset your system to get a proper flame. Works the same for round burners with a tube inlet and straight tube burners.
