RE: Wall tent stove question.
Talked with the experts at Davis Tent regarding the importance of the chimney damper. Basically, the chimney damper in conjunction with the stove damper gives one greater control over burn rate and heat output in the stove. Load up the stove at night before turning in and damper the fire down with the stove and chimney damper and you're more likely to still have a fire going in the stove come morning, than if you just used the stove damper (no chimney damper). It's not critical to have a chimney damper installed, but it does give you greater control over the fire in the stove.
Bugs.
