I think that that's the point.
The limestone is intended to neutralise the acid.
The Viessmann link above also shows a neutraliser. You can get marble
chips for landscaping, which would do.
Can't you run the condensate in plastic down one floor below, or into,
a waste from a wash-basin or bath? The waste water should then dilute
the condensate enough to avoid a problem.
