Can it be modified so the exhaust pipe makes a 90 degree bend after it exits the house? Is the hood necessary?

To be clear; you may install a 90-degree elbow before the fixture (hood) that is attached to the outside of your home. I think that's obvious. The hood is necessary for the product to work as intended, that is: it's designed to propel the exhaust away from the building with a rather small amount of airflow. The hood has two venturi slots on its sides. These entrain and mix outside air with exhausted air and are necessary to achieve the effect. You could eliminate the hood, but now you'd need more airflow to propel the exhaust away. This means more blower strength and more exhaust noise. If you're going to do that, I'm not sure it makes sense to buy this product. To be clear; you may install a 90-degree elbow before the fixture (hood) that is attached to the outside of your home.

Yes you can add a 90 degree elbow to piping. You would to need to build a chase or cabinet to install the blending head. Do not go up vertically ,you don't want to collect water in the pipe.

Just my opinion... I am not an airflow expert...I don't think it would have a major impact. Ours makes a 90% before exiting and it doesn't cause any issue. depending on your setup I would be most concerned with distance between the fan and exit point...

I don't think so. You can do that by using the roof vent with exhaust flapper.

You can definitley fit it... Hard to say what the minimum would be but as long as you're willing to alter the chimney height accordingly (Just cut it), the base of the exhaust hood would fit just fine - Looks great installed. Best of luck!

John... I had the same problem as I want to put the stove in my cabin and the chimney must extend higher than the roof. I know of no place to purchase the same size pipe as with the stove so my solution was to go to my local muffler shop and have him custom fabricate a section of 2 1/2 inch exhaust pipe to my specs. They were able to match the diameter of the pipe to the existing pipe by flaring the ends. Keep in mind though that in order to maintain the proper draft, especially in cold weather, the length outside the house must be insulated. This is very important. Wrap the chimney with fiberglass matting and protect it against rain water and you will be all set. Hope this helps you. Phil John...

I used it the way it is made. I don't think it can be changed to any other position. It is designed to fit between the joists, so exhaust outlet goes parallel to the joists.

no, it is made to be bent to help make it easier to install if the head room above the heater is limited.

Although the initial exhaust from the unit is 4", it can be reduced to 3" (Rinnai sells various termination exhaust adapter ends, depending on your house. We bought a right angle one that terminates at 3"). Although I am not a professional, I assume that if your exhaust vent pipe is at least 3" it is fine. If less, you should check with the company.

You don't need to install anything. The exhaust pipe is a short plastic pipe, but the air flow is not too strong. I have it in my kitchen and while it does warm up the area, it's not too bad and I never felt like I need to direct the airflow through the window.

The pipe is concentric with both intake and exhaust. If you had to you could fabricate something that would work. I doubt it would pass inspection without a lot of paperwork. If you decide to do it make sure to include slope in the pipe because there will be condensation. Either up or down slope will work.

Yes. The exhaust doesn't always fit perfectly.. I had to take it to a local exhaust shop and they altered one of the welds.. Only cost me 50$

You can change the orientation to make it either. Recirculate up out the top or exhaust out the back. I have a hole in my wall so I made mine an exhaust. It is pretty easy to change

Are you asking if you have to adjust the computer after installing this kit yes if you got after market pipes .. you will still run lean if all you do is install the breather kit but not enough to cause immediate damage but you need to do it asap

Not sure about your questions but here are some numbers that might help you. The tip is about 4" diameter circle on the outlet side and 3" on the inlet, that's outside dimensions. It's 9" long on the top and 8" long on the bottom since it's slanted down. And make sure you exhaust pipe is 1-3/4" diameter or bigger otherwise you won't be able to clamp it on without modification.

Of course you can attach PVC to it. Thats how Ive always done it, or the flex hose too. Its just common 2" threaded PVC piece you find at any home depot. Its a slip on the other side so you can glue in a 2" pipe and go from there. Both the intake and the exhaust are the same finer thread.

Honestly, I really don't know since I modified mine so I could just stick it on the hood. Sorry I can't answer your question.

No, This particular piece mounts to the top of the exhaust hood. It only redirects the filtered air back out through the louvers in the picture. The exhaust hood does need and an outlet though.

Yes. You'll need to have the clamped end expanded about 1/4". Any exhaust shop can do it. Also, there's no bracket to connect the exhaust to your foot pegs as the photo shows. You won't need it. Mine doesn't move.
