If your inner cover is made of masonite, place two "sticks" on top of the
frames
to prevent inner cover BENDING from weight, and then place the gallon jar
feeder directly over the inner cover hole.

Only in extremely cold weather have I ever had to put the jar directly on top
of the frames, and those wooden top bars of frames would not warp even if the
jar weighed 100 pounds.

I saw your note about the predicted 15 days of cold weather and your arriving
bees.
Me thinks you worry too much!  You can hold those bees in a cool room and
dark for
several days until you get a couple of hours of SUN and 50° weather to
install them.
Just MAKE SURE they have sugar syrup to eat upon installation.
