Duravent 05SC B-vent Storm Collar 5 Inches Adjustable

Product Description

The DURAVENT 05SC is an adjustable storm collar designed for B-vent installations at roof penetrations. It seats above the roof flashing and forms a weather-resistant seal around the vent pipe, blocking water intrusion at the point where the flue exits the structure. Built for 5-inch B-vent pipe, this collar is a standard flashing accessory in Category I gas appliance venting systems. HVAC technicians and gas appliance installers fit this collar as part of a complete venting assembly on residential and light commercial jobs.

This storm collar is intended for use at roof penetrations on Category I gas appliance venting systems, including natural draft furnaces, water heaters, boilers, and similar atmospheric-vented equipment. It pairs with corresponding B-vent roof flashings and 5-inch DVP pipe assemblies. The adjustable design accommodates variation in installation angle and flashing gap, making it practical across a range of roof pitches and field conditions.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance installer familiar with local venting codes and NFPA 54 requirements. Shut down and allow the appliance and venting system to cool completely before working at the roof penetration. Seat the collar firmly over the vent pipe above the roof flashing and secure it according to manufacturer guidelines to ensure a continuous weathertight seal.
