If you break the combustion seal ie take the case off yes.
ok, this boilers combustion chamber has a internal casing and i've not removed that only the main case. I guessing your talking about the main casing..
I only wanted to descale the heat exchanger and i might have to change the diverter valve, I'm guessing this is a no no, then

like i say dont take the case off the combustion chamber 
my own personal opinion is you shouldn't touch boilers full stop unless your a RGI, sometimes when I have a boiler cover off I see things, the signs that things are not right. You can certainly work on it if your not touching anything gas related but sometimes it is not so clear cut, take circuit boards, some have setting for ignition and burner pressure which your average Joe wouldn't know about
