Lola Rosier Posted November 8, 2022 Report Share Posted November 8, 2022 Hi there, I recently acquired a Duncan EA-820 and was curious as to a proper ventilation system for our circumstances. I’d be using it in the basement and can vent through part of glass block window, but I’m unsure the best method to vent considering the return vents for the HVAC. The Duncan has a single hole drilled in the top of the fiber lid. Considering our setup, what’s the safest route - downdraft vent or overhead? If downdraft, I could drill into the base, but there is a “hearth” shelf on the bottom and I can’t place posts on the fiber bottom between the hearth shelf and lame fiber bottom for airflow. Sorry if that’s too much info, but thanks in advance for your time! Quote Link to comment Share on other sites More sharing options...
neilestrick Posted November 9, 2022 Report Share Posted November 9, 2022 @Lola Rosier If you need to vent both heat and fumes, then go with an overhead hood, like the one Vent-A-Kiln makes. If you have a low ceiling get the wall mounted swing arm. If you're only worried about fumes then get a downdraft vent. The Orton vent is really cheap on Amazon right now. I'm not a big fan of the spring mounted cup since it can be difficult to get it to sit evenly against the bottom of the kiln and can easily be knocked out of alignment, so I prefer to screw the cup to the side of the kiln near the bottom. From a safety standpoint either one is a good choice. If you have a window and a fan that can bring cool air into the space, get the downdraft and use the window for cooling since the downdraft will be half the price of the hood.

Lola Rosier Posted November 9, 2022 Author Report Share Posted November 9, 2022 Awesome, thank you for the recommendation! I’m not so worried about heat up by the lakes in winter (call me foolish come summer, we’ll talk then), so downdraft sounds like the way to go. Should I just leave the little hole in the lid open, or plug it and drill the holes elsewhere? Quote Link to comment Share on other sites More sharing options...

The hole in the lid is probably bigger than you need. Plug it. Most kilns are leaky enough that they don't really need holes in the lid, so I would try it without making any holes first, you can always add them later.

Lola Rosier Posted November 10, 2022 Author Report Share Posted November 10, 2022 Good point, the previous owner said she stuffed ceramic fiber in the rim actually - I think heat was coming out by the handle. Ty again! Also thank you for the questions you’ve answered in another thread I found about troubleshooting this kiln - I see I’m potentially in for it… neilestrick 1 Quote Link to comment Share on other sites More sharing options...

Totally normal. Best not to mess with loose fiber unless you really need to. Lola Rosier 1 Quote Link to comment Share on other sites More sharing options...
