Draft flow/top vent calculations...

[Gwanger]

Hey Gwanger...
Turn your burner on and count how many individual propane jets it has. Then take 15,400 and divide it by that number. Now you know how many BTU's you are reducing with each one you cover with a screw. This is how you dial the heat in. I recommend spreading them out, don't bunch them up all on one side of the burner or you will get uneven heat and hot spots in your smokehouse.

Indaswamp thank you again I will do the math b4 closing off jets in burner.I will check the temps again tomorrow, maybe Mon. my daughter and husband just bought first house and need help moving stuff on Sunday. Thnx again.George, I thought gator would taste like chicken. LOL

The jets need to be close enough together to light one another... Not like lighting 70 birthdays candles..

Dave thnx for info,I will look b4 I leap.

AND... the orifice in the venturi of the burner also regulates the total BTU output of the burner......

Thnx for added info Dave

The area of the inside cross section of the pipe between the venturi and the burner plays an important part as well. It needs to be the correct size and length for proper fuel mixture and to pull in enough air for proper combustion. If it is too large, the venturi will not work properly.
