Completing the Installation
1. Use a sealant appropriate for contact with the building materials
present and for the temperature requirements of the installation to
prevent air leakage from unconditioned spaces is recommended. If
gaps between unit housing and ceiling are great, additional material
(backing rod, ceiling material) may be required.
NOTE: This fan is rated for direct insulation contact (Type IC) and it is
recommended that this fan be completely covered by insulation in order to
reduce heat loss or gain to unconditioned space.
2. Reinstall the fan's wire compartment cover. Rotate the blower wheel
by hand to ensure it spins freely. Plug the fan's quick connect motor
cord into the receptacle. This cord will only fit one way into the
receptacle (Figure 11).

into position (Figure 12).
