<strong>Yahoo Message Number: 82236</strong>Does anyone have a document which descibes the items in the plumbing diagram for the Hurricane heater? The diagram I have has some items identified with numbers in sguares and these are listed in the diagram, but other items are labeled with numbers and letters in circles and I have no listing of what these are.<br/><br/>Don Smith<br/><br/>2002 Intrigue #11430
