Metal-fab MF-5D6 Direct Vent Straight Pipe 6 Inches

Product Description

The METAL-FAB MF-5D6 is a straight length pipe section designed for direct vent combustion appliance installations. Direct vent systems draw combustion air from outside and exhaust flue gases through a sealed, two-pipe or co-axial assembly, keeping combustion air isolated from conditioned living space. This pipe section measures 6 inches in length and serves as a building block for routing direct vent runs in residential and light commercial applications. Licensed HVAC technicians and gas appliance installers use components like this to complete sealed combustion venting systems on furnaces, boilers, and water heaters.

This straight pipe section is used in direct vent venting assemblies where a sealed flue pathway is required. It is suited for residential new construction and retrofit installations where the venting run requires a short straight segment to complete the layout. The 6-inch length makes it practical for tight routing situations, transitions near the appliance collar, or final connections at the termination point. It is compatible with other METAL-FAB direct vent components of the same diameter series.

Installation Notes

Installation must be performed by a licensed HVAC technician or qualified gas appliance installer in accordance with the appliance manufacturer instructions and applicable codes, including the International Fuel Gas Code (IFGC). Always shut off gas supply and disconnect power to the appliance before beginning any venting work. Verify that all joints are fully seated and sealed per the manufacturer specification before restoring the appliance to service. Do not mix direct vent components from different manufacturers or diameter series without confirming compatibility.
