Wiring the Hood with an Inline Blower

To minimize noise in the kitchen, these blowers are

mounted along the duct line anywhere between the kitchen

and the exterior wall. If there is easy access to duct line (in

an attic, for example), this may be an appealing option.

1. Remove junction box channel covering the wires (see

Figure 9 on page 11).

2. Remove circular knockouts (Figure 9 on page 11).

3. Install 1” (25.4 mm) conduit connectors.

4. Run black, white, and green wires (#12 AWG) in 1”

(25.4 mm) conduit from power supply to junction box.

5. Connect the power supply wires to the hood wires in

the following order: black to black, white to white, and

green wire to green ground screw on chassis. Use

spring type wire nuts.

• Wire nuts should be spring type wire nuts rated for

a minimum of two (2) #18 gauge wires and

maximum of four (4) #14 gauge wires, UL & CSA

rated to 600V and 302°F (150°C).

6. Connect the “pigtail” to the connector inside the

junction box.

7. Run five (5) wires (#14 AWG) in 1” (25.4 mm) conduit

from the inline blower to the second conduit connector.

8. Connect the inline blower to the pigtail wires as per

Figure 20. Connect the inline blower green (ground)

wire to the ground screw in the junction box.

9. Reinstall the junction box channel.
