3.1 Garnish Installation Steps
- Prepare the Opening: Ensure the 14" x 14" roof opening for the Fan-Tastic Vent is clean, dry, and properly sealed around the exterior vent unit.
- Position the Garnish: Align the KX2040-81 ceiling garnish with the interior opening of the Fan-Tastic Vent. The garnish is designed to fit snugly against the interior ceiling surface.

Ensure screws are driven straight and tightened sufficiently to hold the garnish firmly without overtightening, which could crack the polycarbonate material.
