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.
