It prevents water infiltration around the pipe opening, protecting the surrounding roof deck and interior structure from moisture damage. Licensed HVAC technicians and roofers install this component as part of a complete venting system on residential and light commercial applications. The collar fits over the vent pipe and is secured against the roof surface to form a weather-tight barrier.\u003c\/p\u003e\n\u003cp\u003eThe S4RVSC is used where a 4-inch vent pipe, B-vent, or flue exits through a roof. Typical installations include gas furnace flues, water heater vents, and similar single-wall or double-wall vent systems that require a finished, weatherproof roof penetration. It is suited for both new construction and retrofit service calls where an existing collar has deteriorated or was never properly installed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch nominal pipe size for precise fit on standard 4-inch vent and flue pipe\u003c\/li\u003e\n  \u003cli\u003eDesigned to block wind-driven rain and debris from entering around roof penetrations\u003c\/li\u003e\n  \u003cli\u003eSuitable for use with B-vent and single-wall vent pipe applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with both new construction installs and retrofit replacements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement storm collar for 4-inch residential and light commercial vent pipe roof penetrations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified roofer.
