Let me try and re explain the oven used
No other setting would start at the 145 setting. They were all like 200 degrees or higher.
Which operating temperature of all the units were up to approx 140 or higher.
We could not start at 200. Limitation of equipment we used.
Also other settings were going to make it harder to mount equipment in there as there would be burners turned on above or below. Which in turn we might as well used a normal oven. Which we were not prepared to do.
We did the best we could do with the equipment we got.
