We just installed a new L&L kiln (Model e23T-208, Serial # 050916-B-CWK) and L&L Vent-Sure Downdraft Kiln Vent System with the Vent Doubler System so we could also vent our existing Skutt KM1023. My question involves the size of the central duct (which I understand to be the flue that exits the room). If I understand correctly, on page 6, the kiln vent manual states that for 2 kilns the central duct should be 6”. PLEASE KEEP READING! Our central duct is 4”, BUT we will ONLY BE CAPABLE OF FIRING ONE KILN AT A TIME. With the idle kiln dampered off, will the 4” central duct be adequate/acceptable for this situation?

*****************
The volume of air to be moved is actually for one kiln at a time only in this scenario so a 4" duct is perfectly acceptable. Some general thoughts: The table on page six of our instructions is meant as a general guideline in any case. The larger size of the duct reduces the static pressure which allows a higher volume of air to flow assuming the same input (our fan in this case).

So I’ve had a Skutt KM818 that I bought used a few years back that wasn’t in too bad of shape, but after changing the elements in it a few times, the bricks were getting so hammered & I had had a few mishaps in it & I was tired of using element pins and it was needing some TLC, so when this J18 appeared on our local want ads, I snagged it up. The top was the only part that looks used. Inside it looks brand new! I took the controller & S-tc out of the Skutt, took the manual controls off the J18 and voila!, you have a LLutt! Fires like a champ! Just thought I would share and I am so glad to not have to change the elements in that Skutt again! I might use it for Raku!!! Sincerely, one of your faithful L&L followers!! Jeff
