Thank you for asking. That depends on the model of the water heater you are referring to. The venting listed above would all need to be the same 3x5 concentric stainless steel vent and can not use pvc. For any further questions please contact us directly 866-720-2076.

I installed mine on an inside wall and have 3 sections of pipe to reach the outside wall. All you need is a straight line from the heater to the outside wall. Read the instructions on how to slope the horizontal vent and there will be no problems.

can I use this as an exhaust system for my generator exhaust going through the wall of carport

Same vent kit was installed on my High efficiency Rheem 18 months ago, so I assume it’s not an issue. I have about 12 ft of horizontal run also.

Would it be okay to install in my unheated garage ?

The tankless heater would freeze if you are in an area that is very cold.

This was installed on our 2nd Rheem we have installed in our home. The 1st one used a straight up and captured air from inside the garage. The new Rheem vented directly through the wall to the outside, with the air draw coming in the same tube. Very clean design and easy to install. It would have been nice to have a 'template' about where to drill through the wall (it requires a drop), but, with some simple math, I was able to accomplish it.

The vent kit went in easy and we needed to buy an extension because of the thick walls in our 1880s home which was an easy addition.

Vent itself was fine. Unfortunately it didn't fit the water heater. I had to modify the pipe where it connects to heater. I was able to make it work but someone not capable to modify or have the tools needed to modify would have been out of luck. I had already disconnected the old heater and ready to install new one when I realized the vent didn't fit. I had no choice but to make it work or go without hot water until I could get another vent kit. Disappointed with the HD website that matches the vent kit fir the water heater.
