VH1-3 & VH1-4 VENT HOOD INSTALLATION TEMPLATE
1. Attach the Vent Hood Mounting Template to the interior of the wall the vent hood will be penetrating.
2. Ensure that proposed vent termination clearances are met before attempting to cut opening through exterior wall.
3. Verify that wall penetration will not come in contact with concealed wiring or plumbing. Using a 1/2” drill bit, drill two pilot holes
where noted on the template. The drill bit must be long enough to penetrate to the building exterior.
4. Attach the template to the building exterior aligning the pilot holes on the template with the pilot holes drilled in step 3.
5. Using a reciprocating saw, cut an opening through the building siding, wall board, etc., following the appropriate lines of the template.
6. Slide the Vent Hood through the opening and fasten to exterior wall using provided screws.
7. Once Power Venter is completely installed and secured, apply a bead of exterior rated caulk between Vent Hood flange and
exterior of building.
