Duravent Stove Pipe DVP 45° Elbow (galvanized) 5" x 8"

The DirectVent Pro 5x8 fixed-length rigid pipe range spans from the 6-inch and 12-inch short sections through to the 36-inch, 48-inch, and 60-inch longer sections. The 58DVA-24 at 24 inches nominal sits between the 12-inch and 36-inch sections and fills the planning increment that is too long for a single 12-inch section but shorter than the 36-inch section. It is particularly useful in vertical installations where the ceiling height creates a rise measurement that requires a 24-inch increment — for example, when two 24-inch sections and one 12-inch section together achieve the total vertical rise needed from the appliance top connection to the ceiling penetration after joint deductions are applied. Combined with the 8-1/2 inch adjustable extension for fine-tuning, the 24-inch section provides an efficient mid-length building block for a wide range of installation heights.

Yes. The 58DVA-24 is a straight pipe section that can be used in any orientation permitted by the appliance manufacturer's installation instructions — vertical, horizontal, or at any angle specified for the installation. DirectVent Pro is designed to allow most appliances to vent both vertically and horizontally per the appliance manufacturer's instructions, and the 58DVA-24 functions identically regardless of orientation. The appliance manufacturer's documentation specifies the permitted configurations, the maximum horizontal run length, the required minimum vertical rise, and any other orientation-specific limits that must be respected for the specific appliance being installed.

DirectVent Pro pipe lengths — including the 58DVA-24 — are generally compatible with DirectVent GS components except for the DirectVent Pro pipe extensions. DuraVent has published a Simpson DirectVent GS to DirectVent Pro Conversion Chart for cross-reference purposes when components from both systems need to interact in a renovation or repair situation. However, the pipe extensions — such as the 58DVA-08A — specifically do not fit DirectVent GS pipe. For any installation mixing DirectVent GS and DirectVent Pro components, confirm compatibility against the conversion chart and the appliance manufacturer's instructions before proceeding to ensure the system maintains its listed status and warranty validity.

The nominal length of the 58DVA-24 is 24 inches. DuraVent specifies that 1-1/2 inches must be subtracted per joint when calculating the installed length of a DirectVent Pro pipe section. For the 24-inch nominal section with one overlap connection, the installed length contribution is approximately 22-1/2 inches after the joint deduction. When planning a complete vent run, the joint deduction must be applied at every connection point throughout the run — a run of three 58DVA-24 sections connected together has three joint deductions of 1-1/2 inches each, giving a total installed length of approximately 67-1/2 inches from a nominal 72 inches. Accurate calculation of the total installed length is required to confirm the configuration remains within the appliance manufacturer's specified minimum and maximum vent run lengths.

The 58DVA-24 and 58DVA-24B are the same DirectVent Pro 5x8 24-inch rigid pipe section in all construction and performance specifications — the only difference is the outer wall finish. The 58DVA-24 has a galvanized steel outer wall, while the 58DVA-24B has a black painted outer finish with laser-welded exterior seams. The black finish is typically chosen for sections of the vent run that are visible in the living space, such as the vertical rise above a gas stove in a finished room, where the black exterior coordinates visually with the appliance and interior decor. The galvanized finish is equally functional and is generally used for sections inside wall cavities, chases, or attic spaces that are not visible from the room. Both finishes can be freely combined in the same vent run as their performance characteristics are identical.

A complete DirectVent Pro 5x8 installation using the 58DVA-24 typically combines it with other fixed-length sections — the 58DVA-12, 58DVA-36, 58DVA-48, and 58DVA-60 — to achieve the precise total installed length. The 58DVA-08A adjustable pipe extension provides the final fine-tuning increment. Elbow sections such as the 58DVA-E45 45-degree elbow and 58DVA-E90 90-degree elbow manage direction changes. A wall thimble is required at combustible wall penetrations. A ceiling support or firestop is needed at ceiling penetrations. A wall or roof termination cap provides the exterior termination. Wall straps support long sections of the vent run. All components must remain within the DirectVent Pro 5x8 system family and be confirmed as compatible with the specific appliance through the appliance manufacturer's installation documentation.
