Okay, all ye owners of these wonderful Shaver furnaces, did y'all opt for the hat/coat hanger on the front outside of your furnace?  Apparently I did and it works as it should.  Holds my hat and coat just fine.
Okay, now that I have everyone's attention.  Apparently I'm missing something here.  While I do understand the principle of a "shut-off" valve, maybe Shaver does it differently.  Yesterday, I wanted to make sure my water level was up in the furnace; I went down to the lower level and opened up the fill valve....came out the back door and heard the water running into the bucket.  "What's this I asked myself?  How can this be?"  The valve on the front of the furnace reads "OFF", yet the water is coming out as though it is "ON".  I turned the valve to "ON" thinking maybe some 4 yr. old kid plumbed it basackwards...and the water still cometh....   
 
So, what am I missing here???  Perhaps the valve is just that, a coat/hat hook?  When I go to "OPEN" the valve, like many do to check the water level...it can b e open for 30 minutes and NOTHING comes out!
And the saga continues.......Guess I'll be calling my favorite buddy again at Shaver...but will wait until I read back from you folks.
