DuraVent DuraTech LDC Storm Collar: the rain guard above your roof flashing
The DuraVent DuraTech LDC Storm Collar is a cone shaped ring that clamps around the chimney above the roof flashing, the cover around the roof opening. It keeps rain running down the pipe from entering the flashing. Every DuraTech LDC flashing requires one, sold separately. The collar’s inner edge and the pipe’s vertical seam above it need high temperature sealant that stays soft. Choose the diameter to match your chimney, from 10 to 24 inches in 2 inch steps.
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. Pipe lengths are 6, 12, 18, 24, and 36 inches. The 18 to 24 inch chimney pipe is made to order and cannot be returned. Stovepipe isn’t available this large, so the chimney starts on a mounting plate on a masonry fireplace, in a round ceiling support box above an appliance, or at a tee outside the wall. A separate finishing collar provides the connection for the appliance’s connector pipe. Need the top piece? See the DuraVent DuraTech LDC Chimney Cap. The DuraVent DuraTech LDC Storm Collar ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
