What are your opinions on a single 4" exhaust? No adjustment, just a capped/uncapped sort of situation.

Actually, let me rephrase that. I took the vent out of the lid I have for this UDS (it was a 22.5" Charbroil dome). I made a hole out of it and put in a 4" 90* ducting because that is what fit. I can make some little adjustments to the opening inside the lid to shrink it down if necessary, but there are no plans to make it adjustable on the fly.

The intake is 3 3/4" pipe nipples with removable caps and 1 3/4" pipe nipple with a ball valve on it. Will the intake adjustment be enough to tame a 4" opening or do I need to plan on making the exhaust a little smaller?


For the record, the ducting is galvanized. I've read all I can on the subject and feel confident that it will be just fine after hitting it with the weed burner.
