"?For ducted systems, visually verify that all necessary calculations are completed. ?For nonducted systems, visually verify that each room has a flow-control valve."Change to "A. Forced-Air Systems? For EQ 6.2, part (a), verify conduct on-site verification that every room has a return, transfer grille, jump duct, or door undercut."? For EQ 6.2, part (b), conduct pressure differential test between closed rooms and adjacent spaces and confirm minimal pressure difference is less than 2.5 Pa.B. Radiative Systems? Verify that each radiator or radiative heating segment has a flow control installed."
