In an ignition assembly for a flare vent having an open terminal end for ventingwaste gases, a hollow tubular stripper is located adjacent a generally upright exterior wall of the flare vent and has a lower opening and an upper opening proximate to the terminal end of the flare vent. A conduit for diverting some of the waste gases from the flare vent to the stripper is located below both the upper opening of the stripper and the terminal end of the flare vent. A pilot has an ignition end to ignite the diverted waste gases in the stripper to produce an ignition flame at the upper opening of the stripper, which in turn ignites the waste gases exiting the terminal end of the flare vent. The pilot is housed in a sleeve having an open first end for receiving the pilot and an open second end for exposing the ignition end of the pilot to the waste gases in the stripper. The sleeve is insertable into the stripper and, when inserted, allows air flow through the stripper to produce the ignition flame and to cool the sleeve. A track is attached to the exterior wall of the flare vent for moving the sleeve and pilot between an inoperative position near the base of the flare vent and an operative position near the terminal end of the flare vent. In the operative position the second end of the sleeve and the pilot are located within the stripper below the stream of waste gas entering the stripper through the conduit.
