Installing the Floor Register

Breakoff Tabs

Tilt Blower Box

Mounting Screws

The blower box mounting bracket is designed to allow mounting into an existing floor. However, it is easier to in- stall all components at the time of house

construction. The mounting bracket as- sumes that floor joists are on 16” cen-

ters. The mounting bracket has break-off tabs that are to be left on only if the floor joists are too far apart to be reached with- out them. To break off the tabs simply bend them back and forth until they break. The following instructions are for installing in an existing floor.

1.Cut a 71/2 x 137/8 hole in the floor at the proper location. The hole must be perpendicular to the floor joists.

2.Place the mounting bracket in the hole as shown. The tapered end of the bracket must be opposite to the side where the air will enter the blower box.

3.Place the blower box with blower assembly removed, down into the bracket, angling it as shown. Slide the blower box down into the bracket as far as needed to tilt it level. Then slide the box in position and attach the duct work (not shown). Install the box mounting screws.

4.Insert the electrical wires for the blower into the box through one of the two holes provided.

5.Using wire nuts, connect the wires to the motor and speed control as shown on the wiring diagram.
