kd4zou Posted April 29, 2019 Report Share Posted April 29, 2019 I was just given this old kiln, it's from the electric hotpack company inc. , model 7009. I have been searching all day for information about it so I can try to get it working again , and can't find anything useful. Specifically, I'm looking for the electrical schematics and a user manual. Also, any other information about it would be great to know, things such as possible age, etc....

liambesaw Posted April 29, 2019 Report Share Posted April 29, 2019 Great thing about old kilns is that the schematics are about as simple as you can get. The hardest part about restoring one is probably going to be getting elements wound for it. I suggest contacting euclids and seeing if they know anything about your kiln and if they can wind elements for you. Link to comment Share on other sites More sharing options...
kd4zou Posted April 29, 2019 Author Report Share Posted April 29, 2019 @liambesaw The inside of the box itself looks fine other than a few hairline cracks , and the heating elements don't look as old as the rest of the kiln so they may have already been replaced. The power cord is dry rotted and crumbling , so I'll be replacing that for starters. I'm sure it will be simple inside, most likely just power to the switch, then switch to the elements. I'm not even sure what I'll do with it after I get it working. Link to comment Share on other sites More sharing options...
neilestrick Posted April 29, 2019 Report Share Posted April 29, 2019 You may not find schematics, but kilns are pretty simple. Power cord, switches, elements. Trace the power with a meter and figure out where it stops. Link to comment Share on other sites More sharing options...
kd4zou Posted April 29, 2019 Author Report Share Posted April 29, 2019 Ok, everything looks good inside other than the power cord, where would be the best place to order one from? 115v / 15a / 2 prong ...... yes it's an old kiln Link to comment Share on other sites More sharing options...
neilestrick Posted April 29, 2019 Report Share Posted April 29, 2019 For a kiln that size, you should be able to find a 20 amp appliance cord at the hardware store. FYI, you'll need to run the kiln on a 20 amp circuit. Link to comment Share on other sites More sharing options...

I have some heavy duty 20a extension cords that I could use but I wasn't sure they would handle the heat, but if an appliance cord can, they should be able to as well.

Mark C. Posted April 29, 2019 Report Share Posted April 29, 2019 The extension cord needs to be pretty short and #12 wire for sure.If they heat up they are not large enough or to long. Link to comment Share on other sites More sharing options...
neilestrick Posted April 29, 2019 Report Share Posted April 29, 2019 6 foot cord rated for 20 amps. Link to comment Share on other sites More sharing options...
liambesaw Posted April 29, 2019 Report Share Posted April 29, 2019 Do you know how hot this thing gets? It sounds like it's a laboratory oven from what I can see of the products they made. Link to comment Share on other sites More sharing options...

I was told it was being used as a jewelry kiln, that's why I've been searching for a user manual, I need to know more about it. Link to comment Share on other sites More sharing options...

liambesaw Posted April 29, 2019 Report Share Posted April 29, 2019 Looks perfect for pizza! Looks like an old casting furnace to me, we use them in the dental laboratory to melt metal in a crucible for casting. Doesnt look adjustable, so might make it hard to fire ceramics Link to comment Share on other sites More sharing options...
kd4zou Posted April 29, 2019 Author Report Share Posted April 29, 2019 Only adjustment it has is low/med/high on that dial. From the very little info I could find, it originally had a shelf , if I can find it, maybe I can make 2 small pizza's at the same time. That gauge that ended up to small to see , goes up to 2500f but that's in the red. Link to comment Share on other sites More sharing options...

Don't want to risk ingesting contaminants. -SD Link to comment Share on other sites More sharing options...

neilestrick Posted April 30, 2019 Report Share Posted April 30, 2019 Since we don't know the max temp of the kiln, once you get it running you should put in some cones and see what it can do. Judging by the shape of it, it was probably not made for ceramics, which means it may not get hot enough for clay work. Link to comment Share on other sites More sharing options...
KR76 Posted August 15, 2019 Report Share Posted August 15, 2019 I too have one of these kilns, which I have used for enameling. It works well. I am interested in selling it, but can’t find much info about it to pass on. Any info you have found would be greatly appreciated! Link to comment Share on other sites More sharing options...
