Impushana embozwe ngokubomvu futhi yenziwe nge-alloy ye-aluminium engasindi, ithoshi lokuconsa lomlilo weWildfire lidizayinelwe ukumelana nokuphathwa kabi okuvame ukubekezelelwa amathoshi aconsayo.Iluphu yokuphepha ikude nelangabi ngakho-ke ayikho ingozi yokuthi uphethiloli ku-loop (i-liquid seal) ihwamuke ekushiseni.Ivalvu yokukhipha umoya yohlobo lwesikulufu yethula umoya phansi ethangini ukuze ukhulule i-vacuum edalwe njengoba kusetshenziswa uphethiloli.I-wick yenziwe nge-fiberglass efakiwe.Isibambo "sokuphakamisa isandla" sinikeza ibhalansi enhle kunoma iyiphi indawo.
