puddle at new hearth stove

[luna]

We recently installed a dry multi-fuel stove (Glen Dimplex 8kw) with an external twin flue, set on a granite hearth (3ftx3ft).
So far we've been testing a selection of fuels and today we've used ecobrite coals, and briquettes.
Anyway - earlier I found a small puddle of water had formed on the floor along one edge of the hearth. I wiped it up assuming one of the kids had spilt something.
Tonight I have noticed the same thing though, in the same spot, after the fire had died down. There isn't any apparent reason I can think of. The room doesn't suffer from condensation and is vented.

Anyone have any ideas? I am stumped.

Check the water levels outside...

What do you mean? Or am I being a bit dense at this late hour?

I would say check for condensation on the stove or rain water coming down the flue and into the stove. It may leak at the elbow or enter the stove

In case of floods, high water tables, etc.
