Don't put anything near the outlet or you could end up killing the occupants
of the house with carbon monoxide gas....this is the extreme end of the
spectrum...at the other end is the fact that your boiler won't function
properly, if at all with it's exhaust blocked - it takes only a small amount
of vegetation to block the outlet - half a dozen leaves is ample.

PS
The outlets on most modern boilers are also the inlet for fresh air to feed
the boiler too.
