I just purchased a new Castle Serenity pellet stove. My previous stove was also a Serenity and lasted 10 years -- something electrical gave out last week that I wasn't able to fix. I set the new stove to the same settings as the old - manual on level 1 with the room blower voltage on max. The new stove is much hotter than the old and the flame is a lot higher than it was in the old. I messaged Ardisam to see if I could lower the feed rate and they said no. Any other suggestions or ideas? If I closed the air damper a little would that help?
