But there are at least 2 Listservs involved, so it could easily split. I will discuss with my webmaster James about having summary information placed on my <a href="http://www.drtlud.com/">www.drtlud.com</a> website. (I do not want to have the interactive discussions there in the comments sections.)<br><br>3. The summary of what has already been communicated is in Erich's comments and Hans' photos (we will want to pull out the 4 photos that are numbers 0186, 0187, 0188, and 0192 .)<br><br>On 11/19/2012 8:56 PM, Erich Knight wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal> <o:p></o:p></p><div id=ygrp-mlmsg><div id=ygrp-msg><div id=ygrp-text><p style='margin-bottom:12.0pt'>Hi Paul,<br><br>The Patio heater conversion is in the same photo stream as the Weber Kettle TLUD, that Hans posted.<br>I had only posted the picture of the stainless steel patio heater previously, not the exploded view with the stainless steel cook pot and wire mesh & chimney replacing the propane gas cylinder. <br>So now I am keeping an eye out for a damaged Patio heater.
