Can I put a Rinnai LP gas OUTDOOR model tankless water heater in my garage?

I am building a house and purchased a Rinnai 2532W LP outdoor tankless water heater. Can I install this model in my garage without venting it?

I also have a set of White Mountain Hearth ventless gas logs. I suppose those need to be vented as well?!

It’s a pain in the butt, but you really should vent it properly for various reasons.
Odorless noxious and deadly fumes built up in the garage, and if the unit is not operating with proper combustion, then the fumes could build up and cause an explosion.
Also the unit may not operate properly without the vent.
The newer models have a sensor in them that detects fumes building up and will shut down the unit if the fumes are detected.
I’m not exactly familiar with the model you have, but most models these days have a combination vent and air intake- in other words, the pipe that vents it to the exterior also has a fresh air intake on the inside of the exhaust pipe.

IT HAS TO BE VENTED TO THE OUTSIDE

Your Rinnai was designed to installed in the outdoors.
If you vent inside of the garage the worst thing that will happen is you will have carbon monoxide poisoning in your home and some one can die.
If you want a unit installed inside, get the indoor model with a direct vent kit.
Good luck.
