How long did it take you to be comfortable with running your stove throughout the night and day when you were at work? I know that the first couple of weeks that I burned pellets over night I would sleep sort of lightly because I wanted to be able to react in case of a fire. We still do not feel comfortable with letting the stove burn when no one is in the house. On the rare occasion we will leave for at most 30 minutes without feeling the need to shut it down.
