    I started this thread in the wood forum as I had planned on going the wood route. During the freezer build, I decided that installing a propane burner would be too easy to do. So, I installed it. The burner is a small burner from a table top grill. When I have it set on low, my temps stay a steady 290 degree's.

    My exhaust vent is 3 inches. How big should I go to help get my temps down by 60 degree's? I don't want the exhaust so big that I lose my smoke etc.

    If you go larger with your exhaust you can always adjust the opening to fine tune your temperature with a baffle, as simple as using aluminum foil to abstruct part of the exhaust opening.

    I do not know where you live but remember temperatures will be dropping as winter closes in on us.

    Another thought on lowering your temperature without changing your exhaust is the add a regulator on your propane gas line to lower the amount of propane reaching your burner.

    How big are your intake vents?

    I would go with a larger exhaust and several intake vents. The intake vents should be adjustable.

    From there it will be trial and error. Let us know what you find out!

    Well, I increased the exhaust hole from 3 inches to 6 inches and boy, what a difference it made!! After running for a solid hour my temps remained a steady 233 degree's! Just about perfect!

    I think it's time to get my shelving installed so I truly see what kind of results I get with this!
