Nope, no screws on top only two hooks, looks like it should just pull from bottom then lift off. times ticking cause i just bought my hammer!

Remove screws ontop look down on boiler to the right and left. Same looking up from underneath.

Then slightly pull cover open by the wall, then pull cover towards you.

Precautions: Isolate power first, make sure no obstacles in way, boiler cooled down, and wear gloves for sharp edges!
