Cold enough (40s) tonight to light my break-in fire for the new Oslo. I understand that you need 3 fires - 200 - room temp - 300 - room temp - 400 - room temp. Does the last break-in fire (400) need to be done right after the second one or can I wait until tomorrow to do the last fire. Or do they all need to be done consecutively. Inquiring minds want to know.......
