Outer jacket on flex disconnected from boot/collar

The outer jacket is not the air seal. On flex, the inner liner connects to the collar; the jacket protects insulation after the air connection is secure.

Stop if

• Can you verify this flex connection before I finish the outer jacket? I want to make sure the inner liner is actually connected.

Watch out

• Do not zip-tie only the outer jacket and call it connected.

Check

• Check that the inner liner is pulled over the collar/boot.
• Verify clamp/tie/seal method on the liner first.
• Then bring insulation/jacket back over the connection.
• Inspect for gaps or exposed insulation at the boot.
