Maximum flex duct

[NJinspector]

Flexible polyethylene ducting - I'm pretty sure the maximum length allowed (in NJ) is fourteen feet. Does anyone have the code reference for this?

thanks much

You're thinking of "air connectors." Their length is limited to 14 feet.

Flexible "air ducts" can be any length.
