Abstract
A combustor extension for a heat gun where the heat gun has a jet pump for mixing pressurized fuel with air to form an air/fuel mixture and a combustor attachment for combusting the air/fuel mixture. The jet pump has a first electrical connector for providing an electrical charge to an ignition device at the combustor attachment for igniting the air/fuel mixture. The combustor extension includes a hollow conduit having proximal and distal ends for extending between and coupling the combustor attachment to the jet pump. A second electrical connector at the proximal end of the conduit electrically couples to the first electrical connector of the jet pump. A third electrical connector at the distal end of the conduit electrically couples to the ignition device of the combustor attachment. The second and third electrical connectors are electrically connected together.
