This is either a 47050 0r a 47582 [dep on if it's a .5 or .75 in pipe]
My unit was installed 11 yrs ago and does not get hot. Removed plate. A service guy by phone says there's a clip to remove before uninstall is possible.
I can't find that clip... the unit appears to be a continuous shaft running into a brass fitting on the pipes.
2 pics show the unit.
