Assuming by keg you mean you have transferred it out of primary fermentation, in which case there is no correct answer.
The general consensus seems to be to keep it a room temperature for the first few weeks (to encourage carbonation through secondary fermentation) then in colder temperatures after (garage/shed etc) for ideally as long as you can leave it.
Some kits clear faster, from my brief experience with st peters kits they do clear pretty quick, 3-4 weeks maybe.
Some kits take longer, Bulldog brews kits for example need as very minimum 6-8 weeks.
In any case, the longer they can be left the better.
