Customer Reviews for Rheem 3 in. PVC Horizontal or Vertical Concentric Vent Termination Kit for High Efficiency Tankless Gas Water Heaters

I installed this myself but unless you can install a HVAC system, I wouldn’t recommend attempting this yourself. It runs great now that it’s online.

I returned it because it was 3" and I was using 2" PVC pipe. The other thing is it also says in installation exhausts and intake air should be a foot apart...

This PVC termination kit works with the Rheem tankless water heaters. I purchased two water heaters along with the connection link cable for the water heaters. I needed two of these to go along with the installation. Came in white, but I sprayed this "Copper Rose Metallic" since it's facing the exterior of my modern house. Everything worked out well with this product. Would recommend.

I am not a plumber or an electrician. I have no experience installing major appliances like a $4,000 tankless hot water heater (THWH) (Intellihot iQ251, First Gen). I was very concerned that this item might not work. And I had no idea if it would fit in the rather cramped space where I ideally wanted to locate it. It all worked perfectly. I can be completely taken apart to be sized, lengthwise to fit a location. I would recommend it to anyone who is installing a high efficiency gas appliance. I am going to replace the double pipes that are used for my furnace later this year. One hint, if you are self installing. Look carefully at the vent holes on your unit. The "straight-through" in this concentric vent for exhausting flue gases. The 45º fitting intake, combustion air. Your installation will be better if you have to 45) fitting pointing up. That way any humidity in the inlet air that might condense in the pipe will not trickle into the unit causing an error. Also be sure to angle the vent down to the heater. It seems counter intuitive (wouldn't you want the vent line to angle down away from the unit so condensate trickles out. But thats not the recommendation of any THWH manufacturers that I researched. In the picture of the vent as it appears outside of the house you can maybe see I hot-glued a piece of stainless steel screen to the end of the tube to prevent any critters from entering.

Arrived broken The fins on the back of the cone piece were broken off due to poor packaging and it arrived two days later than expected I superglued them back on however and the product functions as it should This is the second item I have ordered from Home Depot and both arrived in pieces

I wanted to utilize my existing roof vent from the old tank water heater

If you are installing this Concentric Vent in a "Vertical Configuration" an elbow of 45 degrees is REQUIRED for the fresh air side vent (see picture). I'm totally confused why Rheem/Home Depot would include a 90 degree elbow with the kit. Sure 90 degree elbows can be used elsewhere in custom venting configurations but they are not required. Rheem should include a 45 not 90 degree elbow (with the kit) then let custom installers add their own 90s and vent pipe to complete their custom installations. If they don't see the value in doing the above, they at least should sell a 3" Schedule 40 (45 degree) Elbow Part to fix the kit shortcoming......watch out!

Turned out the unit didn’t fit with our under sink space, and sent it back. Delivery and return service was good

ordered online. Part arrived damaged.

Exactly what we needed for a difficult installation.

Easy to assemble. Fit perfectly

This worket perfect for our tankless water heater install

Very easy to install, by using this, this prevents having to cut two holes , I mounted mine horizontal through my garage wall, i would use it again if I was mounting another tankless water heater.

2 1/2 weeks later and they still can’t give me a straight answer on where my product And now they can’t even give me a refund untill it finds its way to the store next business day is what I was told when I purchased it online

Excellent product, but if you are installing it into a side wall purchase a 45 & 90 degree angle pipes separately.

Very easy to work with.

Although it works fine I did ask if the two inch at 1/3 the price would work in the vertical position, your answer was that it would not, when I received my Rheem tankless water heater the instructions showed that the 2” could be installed vertically. This would’ve not only saved me money but a lot of undue labor and would’ve given a better appearance on the side of my house.

The 3” pvc looked like it was cut with a hatchet, but was covered and did not affect the workings of the device
