Step 3:
Install Blower to Base
•Position the blower so that the holes in the back plate
fit over the studs on the base.
•Verify that the duct extending through the structure is
positioned over the round flange extending from the
back plate of the blower. The inbound duct must
make contact with the back plate to provide a seal.
•Secure the blower to the base with the four nuts
provided.
•Install the remainder of the ductwork to the
downdraft vent in the house.
Step 4:
Connect Electrical
•Cut the blower leads approximately 3" from the plug
on the end of the blower conduit. See Fig. 4.
•Remove the wire box and conduit fitting from the end
of the blower conduit by loosening the screw on the
fitting. See Fig. 5.
•Save the wire box and plug to complete the connec-
tion at the downdraft vent in the house.
•Use electrical cable and connectors that conform to
local codes (14 gauge min. is recommended). Attach
the wire box removed from the blower conduit to the
end of the wire run at the vent. Attach the plug and 3"
leads to the cable at the downdraft vent. Insert the
plug into the mating plug on the vent. Attach wire box
with screws to the vent.
•Check that the red plastic anti-short bushing is se-
cured in the end of the conduit. Install the blower
conduit into the conduit connector on the wire
compartment and tighten the screw. See Fig. 6.
•Attach the green ground leads from the wire compart-
ment, connecting one to the green ground lead on
the blower and the other to the ground lead of the
wiring from the downdraft vent.
•Connect the neutral and power leads from the blower
to the leads from the downdraft vent.
Step 5:
Finalize Installation
•Install the outlet panel to the base plate with 3 screws.
•Fasten the damper assembly to the outlet panel with
4 screws.
•Install the cover with 16 screws.
