The best direct vent termination kit depends on the appliance, vent-pipe diameter, and installation layout. For a low-profile 2-inch horizontal termination, compare the DiversiTech HVENT2 with the SP20285 kits from Folosem and Wosijm. The Obida SP20286 is the listed 3-inch option, while the Rheem RTG20280-1 includes a wall plate and angled elbow. Confirm the appliance manufacturer’s requirements and pipe compatibility before choosing: these kits are not interchangeable simply because they serve a similar purpose.

Folosem SP20285 Horizontal Vent Kit
The Folosem SP20285 is a horizontal termination kit described for high-efficiency fossil-fuel appliances, including tankless water heaters and furnaces. Its stated purpose is to terminate venting while concealing intake and exhaust pipework at an exterior wall.
Best for: Buyers looking for an SP20285-style horizontal kit supplied with screws. The included termination and screws may simplify sourcing the listed installation components, but the product details do not specify every pipe material or appliance model it fits. Verify those requirements before ordering.
Why it was selected: It is directly described as a horizontal termination kit for common high-efficiency appliance categories, which makes it more relevant to this search than chimney conversion or fireplace vent products.
Limitation: The supplied information does not state a pipe diameter or give a complete compatibility list. Do not assume it fits a particular system based on the SP20285 name alone.
Wosijm SP20285 2-Inch Vent Kit
The Wosijm SP20285 is described as a low-profile horizontal termination kit for high-efficiency furnaces and tankless water heaters. Its product details specify 2-inch PVC and ABS piping and a 4-inch center-to-center measurement. They also describe use through a wall or roof, so confirm that the proposed orientation is allowed by the appliance instructions.
Best for: Buyers whose system calls for the stated 2-inch PVC or ABS pipe and whose measurements match the listed spacing. The low-profile design is intended to conceal both intake and exhaust pipework rather than leave exposed pipes at the wall.
Why it was selected: Among the listed 2-inch options, its details provide explicit pipe-material and spacing information that buyers can compare with their installation.
Limitation: The listing says it is suitable only for 2-inch PVC and ABS pipes. Avoid choosing it if your appliance specifies another diameter or vent material.
DiversiTech HVENT2 Horizontal Termination
The DiversiTech HVENT2 is a 2-inch horizontal vent termination kit listed for tankless gas water heaters, high-efficiency furnaces, and other high-efficiency fossil-fuel appliances. The stated dimensions are 9.65 by 2.9 by 13.45 inches. Its low-profile design is intended to conceal intake and exhaust pipework for a more finished exterior appearance.
Best for: Buyers prioritizing a low-profile horizontal termination for a 2-inch system. The product description clearly identifies its horizontal use and appliance categories, making it straightforward to compare with other 2-inch choices.
Why it was selected: It combines a specified 2-inch size with a stated overall dimension and a concealed-pipe design. Those details help buyers assess space and appearance before purchase.
Limitation: The provided product information does not identify compatible pipe materials or list specific appliance models. Check both with the manufacturer before treating the diameter alone as proof of fit.
Obida SP20286 3-Inch Termination Kit
The Obida SP20286 is described as a 3-inch vent termination for 3-inch PVC or ABS piping. Its listing identifies it as a replacement part for Rheem SP20286 and says it is designed to support airflow and exhaust in a 3-inch vent system.
Best for: Buyers confirming that their system requires a 3-inch termination and that the SP20286 reference matches their equipment. It is a useful alternative to the 2-inch kits in this roundup when the appliance documentation calls for the larger stated pipe size.
Why it was selected: It provides a clearly differentiated 3-inch option and a specific replacement-part reference, helping buyers avoid assuming that every termination kit has the same diameter.
Limitation: The listing’s compatibility claim centers on the Rheem SP20286 part reference. Confirm the exact appliance model, pipe material, and termination requirements; the product description does not establish universal compatibility.
Rheem RTG20280-1 Tankless Termination Kit
The Rheem RTG20280-1 is a horizontal vent termination kit for tankless systems. The listed components include stainless steel parts, a 12-inch wall plate with mounting screws, and a 94-degree elbow to facilitate the venting configuration.
Best for: Buyers whose Rheem tankless appliance documentation calls for this termination kit or its specified configuration. The wall plate and elbow are useful details to compare when planning the wall opening and vent route.
Why it was selected: It is a manufacturer-branded tankless termination option with specific included components, giving buyers an alternative to the generic 2-inch kits.
Limitation: The supplied details do not state pipe diameter or provide a full model compatibility list. Confirm the part number and installation requirements against the appliance documentation before purchase.
Buying Guide: How to Choose a Direct Vent Termination Kit
What diameter does the appliance require?
Start with the appliance installation manual, not the appearance of the existing termination. The products above include stated 2-inch and 3-inch options, but a matching diameter is only one part of compatibility. Check whether the appliance specifies a particular termination, vent system, pipe material, or listed part number. Do not reduce or enlarge vent piping unless the appliance manufacturer’s instructions expressly allow it.
Is the kit for a wall or roof termination?
Many products in this roundup are described as horizontal wall terminations. The Wosijm listing also mentions vertical roof installation, but the chosen orientation must still match the appliance instructions and applicable requirements. A termination intended for a wall is not automatically suitable for a roof. Confirm the route, clearances, and terminal placement with the product documentation and a qualified installer.
Does the pipe material match?
Material matters as much as diameter. The Wosijm listing specifically identifies 2-inch PVC and ABS, while other supplied descriptions do not provide the same material detail. Check the appliance manual for approved vent materials and compare it with the exact kit documentation. Do not infer material compatibility from a product title or from another kit’s specifications.
Which option is better for a clean exterior appearance?
The Folosem, Wosijm, and DiversiTech products describe designs that conceal intake and exhaust piping or provide a low-profile finish. Compare their dimensions, pipe spacing, and mounting arrangement with the exterior wall and planned pipe layout. A concealed design can create a tidier appearance, but it should not take priority over correct venting, clearances, or the manufacturer’s approved configuration.
What should be included in the package?
Review the listed components before buying. Folosem states that screws are included; Rheem lists a wall plate, mounting screws, and a 94-degree elbow. The other product descriptions do not provide an equally complete component inventory. If the installation requires adapters or additional parts, confirm what is needed from the manufacturer or installer rather than assuming they are included.
When should an installer verify the selection?
Have a qualified professional check the kit when the appliance model, vent path, pipe material, or termination location is uncertain. Venting affects safe appliance operation, and local installation requirements may apply. A product listing is not a substitute for the appliance manual, building requirements, or professional review.
Frequently Asked Questions
Are all direct vent termination kits interchangeable?
No. Kits can differ in diameter, pipe material, layout, components, and appliance compatibility. Match the exact requirements in the appliance documentation.
Can I use a 2-inch kit on a system with 3-inch vent piping?
Do not assume that you can. Use the diameter and vent configuration specified by the appliance manufacturer. Ask a qualified installer if the system requirements are unclear.
Does a horizontal termination kit always install through an exterior wall?
Horizontal kits are generally described for wall terminations, but the approved installation depends on the specific kit and appliance. Follow both sets of instructions.
Are screws included with every kit in this guide?
No. The Folosem listing says screws are included, and the Rheem listing specifies mounting screws with its wall plate. Check the remaining product details for the exact package contents.
How can I confirm a replacement kit will fit my Rheem appliance?
Compare the appliance model and required part number with the kit documentation. The Obida listing identifies SP20286, while the Rheem listing names RTG20280-1; those references should not be treated as interchangeable.
