Added a 273 cfm squirrel cage blower to my arch. The arch is not an airtight, it’s natural draft. Any thoughts on whether the draft door should be open or closed when the blower is on? Thanks in advance for any feed back

Keep it closed. The blower will give it all it needs, better than the draft door, and if you leave the draft door open you could lose some of the blower air which could blow out the open door rather than go up to give air to the fire.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
You will be making your arch air tight. I have seen some awful smokey sugar shacks from the smoke that will blow out from the smallest of cracks around pans and doors. You are pressurizing the inside of the arch and the smallest of cracks will puff out smoke.

I guess smoke escaping would depend on how good the draft is on your rig. I never had smoke escaping mine and it is not airtight. Mine has almost a 1/4" space between the feed doors and when I just had a 400+ CFM blower it did not smoke, nor does it ever with my high pressure OAF/AUF. If you get smoke, add more stack height. Mine is 19' high with my 3x8, it was also the same height back when I had a 2x6 because I have 10' walls, a steep roof and it extends at least 2' above the cupola which is only about 2.5' away..

I'm with Dave on the door being closed. Every rig will act differently and only time will tell if yours will billow out smoke. I have seen a brand new major manufacture with non air tight doors become impossible to run at high fire because of the gaps in the doors. He has plenty of stack and we slammed the doors with fire blanket in them to help get thru the season.
You can adjust your AUF until it doesn't have any smoke escape by restricting intake. As the evaporator heats up about an hour into the boil it will also draft better. If you adjust your air you can also feed wood without shutting the air down.

If using a low pressure blower (squirrel cage) put it on a dimmer switch so you can adjust the amount of air put in. I us a sharpie to mark high end, and low end (I leave blower on turned down when I add wood). After a season you will get to know where you need the switch to be at for the hottest fire. Some days will be different then others.
