Flashings are used to seal the opening where the Direct-Temp pipe penetrates the roof and to divert rain and snow down from the roof and away from the venting system. It is important to choose flashing that matches the pitch of your roof. This adjustable flashing works for 6 12 to 12 12 pitch. Direct-Temp system features stainless steel inner and heavy duty galvanized steel outer walls. Heavy duty centering brackets keep inner pipe centered and chamfered edges allow for easy slide-together assembly. The free-floating inner liner allows the pipe to expand and contract under high temperature, without creating gaps or stress points. The LockTab(r) is a unique design that allows for 360° rotation while securely locking the sections of pipe together with just a push of the tab.Siliconozed fiberglass seal LockTab security Pipe rotates easily to align system components No sealant required High efficiency performanceBase Length: 31-7 8 Base Width: 27 Finish: Stainless Steel Galvanized Steel Painted Black Fuel Type: Gas Height: 4 Inner Wall: 304 Stainless Steel Joint Connection Overlap: 1-5 8 Joint Connection Type: Twist-Lock standard on all diameters Material: Galvanized Steel, Stainless Steel Outer Wall: Heavy duty galvanized steel Pipe Class: Direct Vent Pipe Inside Diameter: 5 x 8 Pipe Shape: Round Pitch: 6 12 - 12 12 UL Listed: Yes Vent Construction: Double Wall
