If they are defects and enhancements they should already be excluded
from the burndown chart (through a bug really - but this may be a
feature for you)
As soon as we fix this, you will need to make sure that the tickets you
want to ignore from the burndown chart don't have a story_point or
remaining_time attribute.
To easily change the type of many tickets at once, I would recommend the
csv export and import on which you can find more in the help that
acompanies each agilo installation, for example here:

Hope this helps!
