PLAN THE INSTALLATION
1.
Locate the blower so the length of the duct run and number of
elbows and transitions needed are kept to a minimum.
Please note = when using blower with the Broan Eclipse
Downdraft: The downdraft has a 31A'' x 10" discharge.
Transitions are available to connect it to the 10" round
inlet on this exterior=mounted blower.
2. Where possible, blower should be centered between wall
studs or roof rafters.
3. Avoid pipes, wires, or other ductwork that may be running
through the wall.
4. Be sure that there is enough space for any transitions that may
be needed between the blower and the connecting ductwork.
5. For best performance, locate transitions nearest to ventilator
(i.e. downdraft).
NOTE: Horizontal discharge requires relocation of the duct open-
ing cover plate. See hood manual for instructions.
