Rinnai224053 Vent Pipe Extension, 39 Inch

Worked perfect for my Rinnai tankless water heater. I measured a little long, ordered one extra to be sure I had enough. Seller build com quickly approved my return of the extra pipe. Cant say enough good things. Dont try to build your own vent, I dont even know if you can. But if you do have a long vent like I do. Be sure to read your installation manual because there is a small dip switch inside the rinnai tankless. I had to remove the front screws hidden under the side trim pieces, look inside and flip one of the dip switches to tell the heater to use a long vent instead of short vent. I couldn't find any documentation on what defines a long vent but I figured it was any length longer than about 5 feet which would be if it piped right out the wall it was mounted on.

I used this on a Rinnai Gas Tankless Water Heater. I ran the venting strait up through the attic and then the roof of my garage. I needed this to extend through the attic to the piece designed for the roof.This was just as described and fit perfectly. This is both the exhaust and intake in one and you don't need to worry about adapting PVC piping, etc, so it saves time at the hardware store!

worked great no problems

The pipe worked as expected. It went together easily and seems solid. I did not have to cut it, but it seems like it would be easy if I did. The directions were clear and well written.

Snaps together very easily

Great price and easy to make the proper size

Perfect for our install needs and a good price.

Perfect pipe just cut down to length needed

No problem work's good the color it is white good for me system

It came quick and installed easy. Too bad the home builders didn't do it right the first time, would have saved me from fixing it.

Fits exactly on my needs and expectations.
