This hanger keeps B vent sections properly aligned and suspended along their run, maintaining the clearances and slope required by venting codes. It is a straightforward mechanical support component installed by HVAC technicians and plumbers during new B vent installations or vent system repairs. At 0.39 pounds, the 4vph is lightweight and easy to handle on the job site. Its steel construction provides the rigidity needed to hold round B vent pipe securely over the life of the venting system.\u003c\/p\u003e\u003cp\u003eThe 4vph is used wherever 4-inch B vent pipe requires intermediate support along a horizontal or near-horizontal run. B vent systems are common in residential gas furnace, boiler, and water heater applications where natural draft venting through an interior chimney or dedicated vent chase is required. Proper hanger spacing is critical to maintaining the required rise per foot of horizontal run and preventing sag that could restrict flue gas flow or allow condensate to pool. This hanger is installed during rough-in or service work on these vent systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSized for 4-inch B vent round pipe\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigid, durable support\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.39 pounds for easy single-technician handling\u003c\/li\u003e\n\u003cli\u003eDesigned to maintain proper pipe alignment and slope along vent runs\u003c\/li\u003e\n\u003cli\u003eStandard pipe hanger form factor compatible with typical vent installation workflows\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style support hanger for 4-inch B vent round vent pipe systems in residential and light commercial gas appliance venting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with NFPA 54 and the appliance manufacturer venting requirements. Shut down and allow the connected gas appliance to cool completely before working on any section of the vent system.
