Support arms

Select one of the four larger (1-1/4" ) element arms. Install the arm between the two plates
using two 10-24 x 1-3/4 inch bolts, split washer and nuts. If you Wish to use the top support
arm, now is when you need to install the u-bolt bracket on the top plate using the same bolts
that hold the arms in and the plates together. Pick any 3 of the 4 holes used to mount the
end of the element tubes. Snug the nuts but do not tighten. If you do not do this now, you
can still do it later, but you will have to remove three of the bolts that hold the element tubes
in the bracket.
Install the remaining three and the shorter feed tube (has mount holes) in the same manner.
