I believe the design intent is to employ Exception 3 to Section 717.5.2 however that exception requires continuous No. 26 gage ductwork with no flexible ducts or terminal connections. Please clarify. I believe this email to be more expedient than a formal letter for just one comment. Let me know if I can answer any further questions. Thank you, Tony CELEBRATING Tony Lee 125 Building Official I Permit Services Y E A" R 5 425.257.8812 13200 Cedar Street, 2nd Floor, Everett, WA 98201 A story worth telling everettwa.gov/permits I Facebook I Twitter Note: Emails and attachments sent to and from the City of Everett are public records and may be subject to disclosure pursuant to the Public Records Act.
