INSTALLATION INSTRUCTIONS
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
SECTION 1
Preparing the Exhaust Fan
1. Unpack from carton and confirm that all pieces are present. You should have:
1 - Grill
1 - Grill Knob
1 - Wiring Compartment and screws
1 - Motor
1 - Housing
1 - Instruction/Safety Sheet
NOTE: This fan is designed to mount between exterior walls 4-1/2” to 9-1/2” in thickness.
2. Remove the motor bracket assembly from the fan housing by loosening the two screws
which secure the bracket in place (Figure 1).
3. Slide the inner housing out from the outer housing and set aside in a safe place (Figure 2).
SECTION 2
Mounting the Housing
1. From inside the house, choose the best location to mount the housing on an exterior wall.
Make sure to locate the housing where there are no studs, electrical/mechanical utilities,
or any other obstructions.
2. Once you have selected the best location from inside the house, transfer the location to
the exterior of the house and confirm that there are no obstructions in the location and
the fan has proper clearance to operate.
3. Once the installation location has been confirmed, cut a 8-1/4” diameter hole in the
interior wall where the fan is to be located (Figure 3).
4. Drill a small hole through to the outside in the center of the 8-1/4” diameter hole, so you
can properly locate the exterior housing (Figure 3).

5. On the siding of the outside wall, layout a 14-1/2” x 14-1/2” square using the small hole
drilled in Step 4 as the center point and cut out the square hole (Figure 4).
CAUTION: ONLY CUT THE EXTERIOR WALL SIDING. DO NOT CUT INTO
THE SHEATHING (PLYWOOD) UNDERNEATH.
6. Once the siding is cut, nail down all the loose ends of the siding (Figure 4).
7. In the center of the 14-1/2” square cut in step 5, mark and cut a 8-1/4” diameter hole
through the wall sheathing (Figure 5).
8. Install 1” x 2” casing strips (not included) for support on the edges of the 14-1/2” square
hole. Secure casing strips to plywood sheathing with screws or nails (not included) and
seal where the strips meet the plywood with caulk (Figure 5).
CAUTION: IF SHEATHING IS NOT PLYWOOD, YOU WILL HAVE TO ADD
ADDITIONAL SUPPORT FOR THE INSTALLATION.
9. If the wall is less than 8” thick, remove one or more of the electrical compartment
clearance knockouts located on the housing (Figure 6).
10. On the interior flange of the housing, apply a generous amount of caulking and install the
housing through the hole and onto the casing strips and secure in place using screws or
nails (not included) through the predrilled holes on the four corners of the housing. Seal
the flange where the housing meets the wall with caulk (Figure 7).
