Downdraft Ventilators

1. The interior

down-

draft blower system is

designed for use with

3-1/4" x 10" ductwork

(can be transitioned

to 6" round). Three

different discharge

directions are avail-

able with side-to-

side adjustment for

accurate alignment of

ductwork.

2. For best performance:

Choose the ducting

option which allows

1. The exterior downdraft

blower system is designed

for use with 10" round duct-

work.

2. For best performance:

Plan ducting which has the

shortest length of ductwork

and a minimum number of

elbows. Check location of

3. The system will operate most efficiently when the ductwork

does not exceed 40 feet of equivalent duct. The chart, above,

shows equivalent feet of elbows and transitions. The number

of feet of straight duct plus the equivalent feet of transitions

and/or elbows to be used should equal 40 feet or less.

NOTE: The equivalent feet of various roof and wall caps has

been taken into consideration. Do not include them in this

calculation.
