Yes, I'd generally leave it for 10-14 days. I've brewed with Munton's Connoisseur range including the pilsner. I've never used the yeast they come with. I was using the pilsner as a base for a saison, so I was using a belgian saison yeast instead.
A quick question on dry hopping. I plan to dry hop for the last 4 days of the ferment. For those of you who use hop bags, do you boil the bag before putting the hops in it and introducing it to the fermenter? I'd hate to stuff the brew.
