This generated a huge amount of combustible gas while simultaneously extinguishing the gas flame. Eventually it heated up to the point that the gas ignited and it blew flaming fuel out of the top of the stove, around the room. A public education campaign tried to prevent exactly this sort of mis-operation.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Regards<u></u><u></u></p><p class="MsoNormal">Crispin<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Stoves mailing list</span><br><span></span><br><span>to Send a Message to the list, use the email address</span><br><span><a href="mailto:stoves@lists.bioenergylists.org" target="_blank">stoves@lists.bioenergylists.org</a></span><br><span></span><br><span>to UNSUBSCRIBE or Change your List Settings use the web page</span><br><span><a href="http://lists.bioenergylists.org/mailman/listinfo/stoves_lists.bioenergylists.org" target="_blank">http://lists.bioenergylists.org/mailman/listinfo/stoves_lists.bioenergylists.org</a></span><br><span></span><br><span>for more Biomass Cooking Stoves, News and Information see our web site:</span><br><span><a href="http://stoves.bioenergylists.org/" target="_blank">http://stoves.bioenergylists.org/</a></span><br><span></span><br></div></blockquote></div><br>_______________________________________________<br>
