I have read, from many sources, that the pipe should not glow red. Because I am a worrier by nature, I worry about a tent fire, and never let my pipes glow red. I am by no means an expert, but I think the door damper and the pipe damper can be used together to produce the desired amount of heat. The door damper controls the rate of burn, while the pipe damper helps to contain the heat within the stove. I am sort of winging this as I write. I would just play around with the dampers to achieve the desired effect. I like it hot when I’m lounging with a glass of wine. Dampers are open. I damp both down when I retire for the night. This means I don’t have to get up so soon to add more wood, and I don’t have to worry so much about a tent fire.
Those thermometer things are inexpensive, and can be placed right on the stove, or they can magnetically placed on the pipe. They show the temperature, and have a red zone that means, “Yikes. Better damp down.”
