Caught this on the Woodstock blog. They sent a crew down to the Navajo nation to install some beta stoves. This picture from one replacement installation for a box stove shows why clearances are so important. These folks thought they had a shield so they could cut clearances. When the shield was removed the truth came out. These folks are very lucky, the folks at Woodstock may have saved this family's lives. (Yes, the flue setup is not pretty either.)
