Duravent 05T B-vent Tee 5 Inches Double Wall

Product Description

The DURAVENT 05T is a double wall air-insulated B-vent tee fitting designed for use in Category I gas appliance venting systems. This 5-inch diameter tee serves two functions: branching an existing vent run and providing cleanout access to the interior of the vent system. The double wall air-insulated construction maintains a safe outer surface temperature while channeling flue gases from natural gas or propane appliances. Licensed HVAC technicians and gas fitters install this fitting as part of a listed DVP B-vent system during new construction or vent system service work.

This tee fitting is used in residential and light commercial venting applications where Category I, fan-assisted or natural-draft gas appliances require a Type B vent system. Typical installations include furnaces, boilers, water heaters, and space heaters that vent into a common or dedicated B-vent riser. The tee is positioned within the vent run where a branch connection or cleanout point is required by system design or local code.

Key Features

• 5-inch diameter double wall air-insulated construction for safe flue gas handling
• Tee configuration supports both branch connections and cleanout access
• Designed for Category I gas appliance venting systems
• DVP series B-vent fitting for compatibility within a listed vent system

Compatibility

Installation Notes

Installation must be performed by a licensed HVAC technician or qualified gas fitter in accordance with NFPA 54, the National Fuel Gas Code, and applicable local codes. Shut off the gas supply and allow the appliance and vent system to cool completely before beginning work. All B-vent fittings must be installed following the vent manufacturer's listed instructions, and the completed system must maintain required clearances to combustibles as specified by the listing.
