Yep. As you can see, all three of your valves are wide open (hot, cold and bypass).
Simply turn the bypass valve, (which you have correctly identified) to be perpendicular to the piping and you will be OK.

In fact, you may find that your water is too hot. If you want to adjust the temp down a bit, just play with opening the bypass valve a bit and use trial and error until you get the water temperature that you want.

Yes, that should be closed for normal operation. The other valves are fine.

See RV Water Heater Bypass Systems for a good reference.

Yes that is the bypass valve and needs to be closed for normal operation. Turn it perpendicular to the pipe.

We have found our heater is not hot enough, after reading here I searched and found my bypass valves. If you see the picture below I believe my bypass valve is wide open. The dealer never closed it and I didn't know to look before this. I am sure someone can confirm this and that it is the correct valve to close. Thanks.

Yep that is the bypass valve. Normally it should be closed. Some people leave it cracked open a little to mix a little cool water with the extremely hot water to temper it.

Thanks. I did as everyone said and WOW is it hot now. So I throttled back the hot a little and now it is perfect. I love this place!
