Apply high temperature sealant W573-0007 (not supplied) to theouter edge of the inner sleeve of the air terminal. Slip the innercoupler a minimum of 2” (50.8mm)over the sleeve and secure using3 screws.D. Apply high temperature sealant W573-0002 (not supplied) to theouter edge of the of the outside sleeve of the air terminal connector.Slip the outer coupler over the sleeve and secure as before. Trim theouter coupler even with the inner coupler end.E. Thread the air terminal connector / vent pipe assembly downthrough the roof support and attach, ensuring that a minimum 16”(406.4mm) of air terminal connector will penetrate the roof when fastened. If the attic space is tight,we recommend threading the Wolf Steel vent pipe collar or equivalent loosely onto the air terminalconnector / vent pipe assembly as it is passed through the attic.
