Venting

So, here is the set up for my Skutt.  On my Back patio.  In that corner, open to the yard with a wind operated vent in the roof.  Does the kiln need a vent if it is outside?  Do I need to cover the kiln when it's operating to keep it warm?  (Crazy question).

What about an Envirovent. Do I need one? Thanks , Tom

Depending on how close she places it, doesn't she need to put something like cement board up against her house to protect it from the heat of the kiln?

Nelle,

You don't need an Envirovent, but they are nice to get the gases out. I don't have one and my kiln is outside. I mostly bisque in it. Envirovent can be helpful with cone 6 glaze firings to keep the kiln even.

I would just read the instructions on the kiln and keep it about 24 from the wall. Or call them and get their recommendation. (Whatever they say though.) And then I might consider the cement board depending on the situation. I usually put up stringers and then mount the cement board to that.

It all depends on how exposed it is to the wind and rain. I might consider some lathing or a slatted wall in the front if the wind will bring in rain.

It needs to be protected from the elements.

Hope that helps.

Manufacturers suggest a minimum of 18" from the wall. You don't mention if this is a computer controlled kiln or a manual kiln. I would really hesitate to put a computerized kiln in this situation (outside even though covered). If you don't have the manual for the kiln, Skutt has a good web site with fairly detailed recommendations for setting up you kiln. They also have great techs at Skutt that can give you the scoop. Make sure putting your kiln outside doesn't in any way void your warranty if this is a new kiln! Also a kiln vent actually serves another purpose in addition to evening out firings. A vent draws out any caustic gasses which would normally seep out of the kiln through any holes. The gasses, over time, seep out through the place where the elements enter the kiln and the gasses can wreck havoc on the electrical components of the kiln significantly shortening the kiln's life. Good luck! Looks like a great place to make pots!

I can cover the kiln with a tarp when I'm not firing. I may put up some clear plastic sheeting that can roll up or down where the patio is open to the yard, if there is rain.

I will consider the cement board. The specs say 12" from the wall, but I'm hoping to get it 18" out. If I crack the lid open during the beginning of the firing, I believe that will help the fumes out and aerate the kiln until the fumes stop. What it the temp I should bring the kiln to before I close the lid. (Skutt recommends this as an alternative to an envirovent if the kiln is outside.)

You're right, Albert. 18". I have read the manual now, which I should have done to begin with. Unfortunately I don't have a completely enclosed space for the kiln. I will take as many precautions as possible to protect the kiln from the elements, and to be sure the fumes, heat etc. are vent out of the space, and beyond that, I'll pray. It couldn't hurt. Thanks, ya'll.

Oh, it is computer controlled but purchased barely used. I'll call Skutt and see if they can give me more info.
