What yeast/blend does it come with? If you add the puree directly to the primary after a few weeks the saccharomyces in the yeast blend could completely ferment out the added fruit sugars not allowing the brett and bacteria to have a turn. This is a case where you want the wild ones to do their work on any remaining sugars to increase the sourness/acidity/funk in the beer.
I would proabably let the beer sit in primary for about 3-4 weeks, then rack the beer on top of the puree into a carboy. At this point, I would also add some boiled/cooled maltodextrin (sacch. yeast cannot consume this sugar) to the secondary as well which will give the bugs/brett some extra residual fermentables plus the puree to work on and sour your beer. Good luck and most of all, be patient with this style of beer.
