Help please..I got my new Castle Serenity installed and running. I was so proud of myself. Got it up and running and got her burning nice and hot. After about 3 hours I turned her back to number 2. Shortly after, I was alerted to a low temp and the unit shut down. I have been unable to get the stove to reignite. I even manually loaded the pellets to try to trick it. This rookie needs some help. I'm tired of being a slave to heating oil.
