Flex inner liner not pulled over collar fully
The inner liner must be pulled over the collar and secured/sealed. The outer jacket is not the air seal.
Stop if
- Is the inner liner fully seated and sealed on this collar before I pull the jacket back?
Watch out
- Do not clamp or tape only the outer jacket.
Check
- Pull insulation/jacket back enough to see the liner.
- Seat the inner liner fully on the collar.
- Secure and seal the liner per approved method.
- Pull insulation/jacket back over after inner liner is right.
- Tug-check gently before ceiling close.
