Use a broomstick inserted into the flue opening to line it up exactly
so it stays there by itself.  Do not depend on those tiny screws to
pull it into alignment as a) they quite likely won't, leaving you
with leaks, and b) they'll strip out.  They're meant to hold the
outer assembly on, not to manhandle the flue into correct alignment.

Any time the beast is out, have a thought for the O-rings holding the
flue pipes into the inside wall casting.  If they leak, the flame
will blow out.  They can either be replaced or sealed with silicone RTV.

Yrs,
