Reviewed by dave - 21st Mar, 2018 duel fuel mantels generic mantles for use with Coleman duel fuel lanterns , with or without the second element there relatively straight forward to fit. the glass globe and header has to be removed for these to be put on but the easy slip on cover and pull off tags make it a 2 second job. after that just light them with a lighter or match and let them burn themselves out. make sure you do it outside as the gas coming off them isnt nice. when cool put your glass globe and header back on. lighting a lantern from that point is easy enough, just pump it up, crack the open valve and set alight to it revealing the most awesome and intense white glow and that old familiar sound of a lantern in the back ground. cant fault it at all. hope this helps
