The GW1949 Wiseway from US Stove eliminates the need for electricity by utilizing a natural gravity feed system that eliminates all of the typical electrical and mechanical parts found in traditional pellet heaters. This patented revolutionary design is EPA certified and UL listed as a non-electric pellet stove. The Wiseway is simple to start and operate. Simply heat the burn chamber and flue with a propane torch and start the pellet flow. This stove uses a natural draft that will take over and ramp the stove up to temperature. Adjustments are simple by opening and closing fresh air intakes on the front of the stove. The window allows you to see the flame traveling up the body of the stove. Since it uses no electricity, heat is radiated off the 3.5 In. tubing and the steel baffles on the back.
