Description

Rheem SP20897 2" PVC Concentric Vent Termination Kit (often referenced as SP20897-2)
A Rheem concentric vent termination kit used to route both combustion air intake and exhaust through a single roof or sidewall penetration for compatible Rheem tankless water heater venting applications where the specified kit is required.

Key Features
  • Concentric vent termination kit for 2" PVC venting
  • Product type: Termination Kit
  • Material: PVC
  • Rheem states the concentric venting is system matched to the water heater for optimal performance
  • Rheem states it allows both the intake air and exhaust vent to pass through a standard roof or sidewall
  • Includes a California Proposition 65 warning (as listed by Rheem)

Compatibility & Applications
  • Listed under Rheem water heater venting parts; intended for applications where a 2" concentric termination is specified for the installation.
  • Must only be used where the manufacturer specifies this exact part number: SP20897 (2" kit).

Installation & Operation Notes
  • Installation should be performed by a qualified technician and follow the tankless water heater installation/service manual and any vent kit instructions included with the product.
  • Confirm roof vs. sidewall termination requirements per the appliance manual and local codes.
  • Q&A guidance notes there is no extended version of this kit; additional length would need to be added separately if required for snow/roof clearance.

Maintenance & Troubleshooting
  • As a vent termination component, issues are typically related to fit, required accessories, or site conditions (roof clearance, weather exposure, or animal/insect screening).
  • If you need protection from nesting/debris, Q&A guidance points to adding a concentric vent screen accessory sized for 2" venting.
  • If the termination location is exposed to weather, Q&A guidance indicates a rain cap may be necessary depending on the application.

User Reviews & Q&A Summary
  • Reviews (themes):
  • Frequently described as a clean, nice-looking installation and a good value compared with big-box options.
  • Common feedback notes easy installation, with some users mentioning they needed an additional fitting (e.g., a street elbow) to complete their specific connection.
  • Multiple reviews highlight fast shipping and that the kit arrived as described.
  • Q&A (themes):
  • Roof termination: Confirmed it can terminate through a standard roof or sidewall; rain cap may be needed depending on the install.
  • Snow/clearance: No extended version is offered; add lengths separately if you need additional height.
  • Nesting prevention: Add a 2" concentric vent screen accessory if you want mesh screening.

I would buy this product again.

The vent was exactly what I needed. One of the first ones that I got was missing parts and appeared to have been a return item. They quickly replaced the vent and sent a return shipping label.

Q: Is there an extended version, my application is for northern MN where the snow accumulation on the roof is well over a foot. I need a longer kit, or need to modify this kit to get above anticipated snow.

Hi Ed, thanks for writing in. This concentric vent kit does not come in an extended version, so any additional lengths would need to be added separately.

Q: Hi, can this kit be used to terminate through the roof? And if so does it require a rain cap? Thank you.

Hi Tom, thanks for writing in. This Concentric Vent Kit allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. A rain cap may be necessary depending on your application.

Q: What is a good mesh end cover rated for gas appliance/furnace venting that I could use with this to prevent bird nesting? I was looking for something with 90% airflow.
