I wrote a few weeks ago about how my basement studio was in a state of upheaval due to the installation of New Gizmo in the back part of the basement. Since New Gizmo replaced the boiler and hot water heater, does not use the chimney for ventilation, I decided to move my kiln and polymer convection oven to the back basement and install a ventilation system using the chimney. I already have a ventilation system in the front basement that I installed for soldering but which I found worked beautifully when I was cooking polymer and firing bronze clay. Read more about that one here.
I still haven’t decided whether to install a downdraft vent for the kiln or to go with a hooded vent that I can use for the kiln and the convection oven. I already made a plenum cup that fits into the kiln’s rolling stand right under the kiln, but I have hesitated to drill the small hole in the bottom of the kiln that the downdraft vent would need to function. If I made a downdraft vent for the kiln, I would have to be able to detach it from the inline fan and connect separate ductwork to hood to ventilate while the convection oven is operating. I think I am going to set up hooded vent first and see how it does before I make the final decision.
Here’s the inline fan I ordered from Amazon. It’s the same one I have in the front basement. It’s not too loud, has a variable speed controller, and does not require any special wiring. I will have to bolt it to a piece of wood to steady it. I could bolt it from the ceiling, too. I will need two 4″ to 6″ vent reducer/increasers to connect each side of the fan to the ductwork. I also ordered them from Amazon. One will connect to ductwork that hooks into the 4″ chimney opening behind the fan and the other one will connect on the other side of the fan to a longer section of ductwork and the vent hood.
My electrician installed an extra outlet for the fan and the convection oven. The Paragon Max 119 kiln runs on 120 volts but does require some additional wiring and a special outlet which Stubewan the electrician also installed. He also left me some metal tape and ductwork to use. Thanks, Stu!
I used a wok lid for the vent hood in the front basement. I will use a stainless steel mixing bowl for the vent hood in the rear basement.
At this point, I plan to attach the ductwork and hood to the wood beams in my basement ceiling and raise and lower the hood with a chain.
I plan to stow the kiln under the stairs and move it out to the middle of the floor for firing. I was hoping to get it all hooked up this week, but Amazon sent the wrong size reducers. Back they go and new ones ordered.
Wish me luck!
