Install the braces the proper width apart as shown above (Dimension C). Secure them in place
using pop rivets or self tapping screws. You will need four pieces, two on the top and bottom.
Slide the heat exchanger carefully into the plenum to check the fit again. Once proper fitting is
verified, you can seal off the ends of the heat exchanger and the hole you made in the plenum
with foil tape made for ductwork.

Installing a Heat Exchanger in a Small Plenum
You can install a heat exchanger in a plenum that is smaller than the length of the heat
exchanger, as follows. Make cuts at the top and bottom of the plenum, usually 4 inches long (the
width of the heat exchanger) as shown below. You may need to do this on both sides of your
ductwork depending on your heat exchanger size.
Cut another line vertically, between the other two cuts, right in the middle as shown.
