Oops round two.
I had been burning the new 6" steadily for two days.
All the new brickwork was dry and warming up. The new stove itself is performing flawlessly!
Each time I added a fresh load of
wood. Thick billowing clouds of stinky grey steam would come rolling around the cap and out the chimney.
However despite cleaning all the yuck out of the first horizontal pipe I was still not getting good exhaust temperatures in the stack.
Temps would rise with a new load of wood... but never even getting to 100 F. As soon as the wood started coaling exhaust temps would fall.
Gain a little and then loose it all.
Yesterday after adding a fresh batch of wood. I was standing out in the
yard watching the grey cloud start pouring out of the chimney.
A sudden thought popped in my head... Its not raining , I should remove the cap from the chimney! Maybe get some better draft going!
Up the access ladder I go, trusty screw gun in hand.
The chimney cap is the old style . Commonly called a "coolie" cap. Basically wide open with 3 legs and a lid. Just
enough to keep out snow and rain.
4 screws hold the cap to the pipe. After removing the last screw and lifting the cap off... what did I see???
I saw the entire bottom of the cap covered in big fat drops of water!!! OH Shit!!! I'm evaporating the water out of the wet ash...
Sending it up the pipe in billowing stinky grey clouds... Where it was condensing on the bottom of the cap...
AND falling directly back down the pipe landing on the still wet ash!!! Keeping a fresh supply of sopping wet ash!!!
Its no wonder my exhaust temperatures won't come up and stay there!
The cap came off yesterday, we will see how long it takes now for the stack temps to rise!
