I have a medium kifaru stove and I'm wondering if anyone has any tricks to keep the fire going longer. I've messed with the damper and tried different types of wood that is available but I can't seem to get a burn longer than 30 minutes. I've seen those logs that burn for extended time frames but I have hear they burn too hot for the stoves. Any tips would be helpful, I have an elk hunt this weekend and the temps are looking to be around 5 degrees
