Thanks for the info, George. That is exactly what I needed to know. My used ovens are older and need the external regulator. Go figure. Even these oldies are gonna be an improvement for my operation. . . if I get them in and running.
I think I have a 1.5" line running from the meter into the kitchen in the shop, which is then dropped with three splits (each with shutoffs) for cook line appliances. Would that be adequate, or do I need to get a separate line from a separate meter run for the oven?
