Thanks To All Who Helped
It has been months and months since I have checked in with the group - we never thought we would see the day when appliances would arrive.
Certainly not complete but the Modernaire Hood (nothing fancy) was installed today and the Bluestar ranges arrived (we did three - a 36 all burner, 24 charbroiler and 24 griddle).
Thanks to all who patiently answered my questions over and over and then over and over again. ;-)
PS. Shout out to Trevor who took care of the hood and worked with the GC and HVAC guy who were baffled on how to install a hood this large.
