I am converting my dryer from LP back to NG. To do this I need to replace the orifice and remove the blocking pin which will be replaced by the limiter. I accidently turned the regulator, which is just below where the blocking pin was removed. Even though I think I just turned the regulator a few turns I would like to be sure it is set right before I put the limiter on top. Is there a standard number of turns that the regulator is set at the factory for NG?

Thanks,
