PLAN THE DUCTWORK

Interior Blower Installation

Exterior Blower Installation

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.

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 floor joists, wall studs, elec- trical wiring or plumbing for possible interference.

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
