Storm collar - 0.4 mm stainless steel flue pipe

👉 The storm collar provides theseal between the roof flashing and the flue (rigid single-wall stainless steel flue liner). It is a metal ring that fits around the flue just above the cone of the flashing: its role is to divert the water running down the flue towards the cone of the flashing, thus preventing any ingress. A bead of refractory silicone must be applied where it meets the flue.

🔥As a reminder, flue pipes must be installed in the direction of the condensates, i.e. male end downwards.
