They are either side of the anode (#47) , They are clearly visible in your photo.

The heads are accessible with a socket wrench. Mine (below) is salt water motor so I get a lot of oxide around the anode which has to be cleaned away .but there is absolutely no need to remove the anode. ( I now almost certainly cannot )

I had to take my anode off as the socket didn't fit with it there. Maybe my socket was too fat. YMMV

That may have been the case. I used a small deep throat socket to get the bolts off. The bolts were on really tight. That's a great point I will run water up that copper pipe you're referring to. Thank buddy
