The Expedition measures 15″W X 18″D X 30″H and weighs 40 lbs without an exhaust stack. The heater uses a vaporizing burner and is controlled by a fully adjustable fuel regulator. The heat output can be adjusted from 10,000 BTU/h to 30,000 BTU/h (0.3 US gal/h fuel consumption on high). The Expedition also incorporates multiple operational safety features such as a patented non flooding burner, fuel regulator with overheat protection, and a fuel shutoff valve. A galvanized heat shield is attached to the heater to protect the user from incidental contact.
