Abstract: A heat gun adapter is an apparatus that allows the use of a heat gun in order to ignite the fuel pellets within the combustion chamber of a pellet burner, specifically manually-ignited gravity-fed pellet burner. The heat gun adapter features a base plate that is placed over the combustion chamber access port after the combustion chamber end plate is removed. A nozzle port is present in order to allow a heat gun to be inserted through the base plate. The heat gun is guided through an annular guide that is positioned concentrically with the nozzle port. The annular guide additionally serves to hold the heat gun in place without user assistance after the heat gun is inserted. The heat gun adapter is held in place between a first track and a second track on the combustion chamber by a lip.
