1. Disconnect power.
2. Remove blower bolt (use 5/16" socket with long
extension). Pull back on motor to remove.
3. Remove flapper (2 bolts - use 5/16" socket).
4. Inspect flapper. Upper tabs on flap must seat in
notches. When laying flat with flap closed, tabs must
not be higher than flush with frame surface. Check
with a straight edge; also check if flap in closed
position makes an air tight seal. Also check flap
opening setting, gap should be 3/8" (10 mm) for
the Empyre Elite XT 100 and 3/4" (19 mm) on the
Empyre Elite XT 200.
5. Generously apply oil to the flap on the sealing
surfaces.
6. To install make sure flap will not fall out of flapper
unit. If this is a problem simply apply tape at flap
tabs before installing.
7. Bolt the flapper unit into place, then bolt the blower
into place.
