Yoder YS640 Damper Placement

djqualls · 03-16-2012, 11:45 AM

Im curious to learn where users of the 640 set their damper. My 640 cooks hotter on the left side and about the same temps on both shelves and the right side cooks cooler in same fashion as well regardless of whether the damper is pulled all the way in or out. I had my cooker set at 250 and probe read 250 but leaf side would only peak at about 235. Right side would run about 275

Here is an overall graph of some temp I ran with my stoker. There are about 5 different snap shots of the same run in my album. Keep in mind the YS640 was set at 250 for duration.

The top Line is the top shelf Right Side of cooker
Second Line is bottom shelf right
third line down is top left rack
4th line is bottom left rack
and the 5th line that starts about 3/4 way thru the cook was I probe I placed adjacent to the factory pit probe

You say it runs hotter on left but the graph shows higher temps on the right, or am I miss reading this?

I have been running mine with the damper "open", pulled all the way to the right. I havent done really any grilling with it but from what I understand that is where the baffle makes the most impact, at the higher temps.

The top & bottom left look like they have very tight range. Right top and bottom not quite as tight. Is right about 40° hotter? What was the position of the baffel on this graph?

I do not see a 5th line.

I started the cook around 19:15 with the baffel closed (rod pushed in)
Then at 20:00 I opened full Open
Then at 21:15 I Closed Again
Then at 22:00 I opened back Up

The 5th temp graph is in one of the other pics that I didn't save, I thought it was on this one. It ran very very close to the Left Side Graphs.

Thanks!

Was there any meat on when you did this.

No. It was a test to map the convection.
