Installing propane heater into existing line

So, I finally finished this project and ended up plumbing with brass fittings into the existing T located inside one of the outside bays. I didn't want to use the one shown in my original plan because it would involve removing a drawer every time I wanted to use the shut-off valve.

I placed the yellow shut-off valve in a hard to reach position so it wouldn't be turned accidentally. I sealed the fittings with pipe dope and checked for leaks. It works great. Photo attached.


Thanks for all the advice.
