Such surfaces shall be prepared to provide an acceptable substrate by attaching minimum 5/8 inch (158 mm) exterior grade or pressure treated plywood. Attach as required for structural integrity.
		H.	All round rigid pipe penetrations ranging in size from 1 inch (25 mm) outside diameter to 6-1/2 inches (165 mm) outside diameter shall be flashed with EverGuardm EPDM Universal Pipe Boots. If it is not possible to fit an EverGuard EPDM Universal Pipe Boot onto the pipe due to the site conditions, the pipe shall be covered with a field-fabricated flashing in accordance with EverGuard EPDM Details.
		I.	Do not install pre-molded and field-fabricated flashing around flexible pipes or conduits.
		J.	The following types of penetrations require the installation of a penetration pocket:
			1.	Rigid pipes with an outside diameter less than 1 inch (25 mm).
			2.	Clusters of pipes.
			3.	Unusual shapes, e.g. structural beams, channels or angles.
		K.	A minimum clearance of 1 inch (25 mm) between penetrations, pipes, conduits, etc. and on all sides of the penetration pocket, is required to assure adequate space for the application of EverGuard EPDM Pourable Sealant around each penetration.
		L.	Flexible penetrations shall be installed in a sheet metal gooseneck.
		M.	Flash all perimeter, curb, and penetration conditions with coated metal, membrane flashing, and flashing accessories as appropriate to the site condition.
