I have seen a lot of pictures of peoples stoves stacked to the gills and people saying they are getting 10 hour burn times, etc. I have an Avalon Zero Clearance Insert. I start the fire and get her up to around 600 degrees, then I put in a couple of splits every hour or so. The stove stays at 500 to 600 degrees and keeps the house at 75 to 78. But when I go to bed I do not wake up every hour to load it up again. I am worried that if I stuff the thing for an overnight burn that it would over fire. Am I missing something or doing something wrong? Can I fill her up or should I just stick to my couple splits per hour routine???
