Various embodiments utilize a novel approach to igniting the natural gas flame that is emitted from the end of the torch. According to one embodiment a rotary diverter within the ignition bell of the GrillGun is used to shunt a portion of the higher velocity gas flow to an area in the bell where the ignition spark is out of the direct burning gas stream. According to another embodiment the ignition bell has a plate that largely covers its open end that reduces the length of the flame that is emitted and focuses it. Still another embodiment has a check valve that operates to stop the flow of gas to the gas conduit when the GrillGun is dropped or tipped over or liquid propane is otherwise presented into the check valve by any other means.
