HOUSING IS PROPERLY GROUNDED.

TO INSTALL IN EXISTING HOMES

1. Determine location of ventilator. Check wall for studs

and obstructions.

2. Working inside wall first, draw a circle 9

⁄

” in diameter

at determined location. Be sure opening is at least one
inch from studs. (See Figure 2.)

3. Carefully saw opening in plaster. Remove just enough

insulation to allow sleeve to pass through, exposing
sheathing. Mark center of the hole on the sheathing. At
this point, drill small hole to outside.

4. Now work from the outside. Using hole as a center

point, draw a circle on outside wall 9

⁄

” in diameter.

Saw opening. In case of brick or stone, use hammer
and chisel to make opening. (See Figure 6.)

5. Install door and outside sleeve assembly from outside.

Caulk and level before nailing tight. Remove tape, per-
mitting damper door to open. (See Figure 3.)

6. Working from inside the house, slide inside sleeve into

place temporarily. Determine whether to remove one or
both knockouts from outside sleeve, permitting outlet box
to drop through. Remove knockouts from outside sleeve.
(See Figure 4.)

7. Slide inside sleeve into place again and pull power

cable through outlet box opening. This will determine
length of power cable to ventilator. Power line should be
run to switch box holding toggle switch. For more efficient
operation, an optional timer is available. Attach cable to
outlet box, using approved connector, and splice cable to
receptacle leads in outlet box cover. Ground wire may be
attached to grounding bolt in outlet box. (See Wiring
Diagram, Figure 5.)

8. Adjust inside sleeve so that flange is flush with finished

wall. Using metal screws, fasten inside housing to
outside housing. Screws are supplied with ventilator.

9. Perform Steps 6-8 as for new homes to finish

installation.
