DuraVent DuraTech LDC Tee with Cap: the outside turn with access for chimney cleaning
The DuraVent DuraTech LDC Tee with Cap is the fitting where a chimney coming through the wall turns upward outside. A bar and bolts hold its bottom cap, which opens for cleaning and inspection from outdoors. DuraTech LDC is DuraVent’s large diameter chimney, an insulated double wall pipe made in 10 to 24 inch sizes for big fireplaces, furnaces, and boilers. Choose a tee diameter from 10 to 24 inches in 2 inch steps. DuraVent documents this wall route for 10 to 16 inch chimneys. The required wall sleeve and tee support bracket come in those four sizes. Wall straps are also needed.
Pick the outer metal before the size. The tee, pipe, and elbows offer galvalume or stainless steel exteriors. Stainless steel is the usual choice outdoors. There is no stovepipe this large. The chimney starts on a support plate on a masonry fireplace, in a round ceiling support box above an appliance, or at an outside tee. A separate finishing collar joins it to the appliance’s connector pipe. Need the wall sleeve? See the DuraVent DuraTech LDC Wall Thimble sleeve. The DuraVent DuraTech LDC Tee with Cap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
