If you are using DuraVent Dura-Vent Type B gas vent systems with a 3-inch diameter and are looking to properly seal and complete the venting project, it is necessary to purchase this Dura-Vent Type B gas vent storm collar. It makes a strong seal between the pipe and the flashing so that rainwater will not get into your pipe and venting system, and therefore, into your chimney and ruin your fireplace's venting system. Just this little accessory plays such a major role in the long-term protection of your vent system by preventing potential water damage with a proper seal.
