- Page 8 INSTALLATION – CARPENTRY The 3.5e/4.4e WHF has been designed to fit a 22½" x 26½" wall or ceiling opening, which corresponds to 24” on-center (O/C) framing. With a few extra steps, the 3.5e/4.4e WHF can be installed in situations with 16" O/C framing.
- Page 9 Cut the opening with a drywall cutter. The opening should be 22½" x 26½". Position the 3.5e/4.4e WHF damper enclosure on top of the joists. Rotate the enclosure as required so that there is easy access to the electrical box and so that the damper doors are centered over the opening (this can be checked from below by depressing the yellow clutch releases located on the side of the actuators and opening the damper doors manually).
