STEP 2
Thumb screw hole location
(This step is necessary only if thumb screws were
not previously used.)
1. Slide the new transition duct into place. Push it all
the way in until it stops. Make sure the transition
duct is straight and not "cocked" relative to the
lateral duct adapter.
2. Center punch the transition duct mounting screw
hole locations into the lateral duct adapter.
Use the holes in the flanges at each end of the
transition duct as a template. Make sure that
the transition duct is all the way back when the
center punch impressions are made.

3. Test fit seals as described below before removing
paper backing.
4. Remove paper backing from each seal and place
as shown. Seal at right side should be located
towards left side of metal flange. It should be
flush with the top rear and extend over the lower
edge of flange. Seal at left side should be located
towards the right side of the metal flange. It
should be flush with the top rear and extend over
the lower edge of flange (as shown in illustration).
Be sure both seals are pressed into place on
the metal flanges (seals should be as close as
possible to screen without overlapping onto it).
