41flathead Posted November 17, 2014 Share Posted November 17, 2014 I'm considering building a forge next to my wood stove and building a Y-pipe to use the same stove pipe out of the shop. I'm not sure if this will work. Has anyone seen or heard of this being done? Any thoughts, opinions, or recommendations would be greatly appreciated. Thanks, 41flathead Quote Link to comment Share on other sites More sharing options...
Frosty Posted November 17, 2014 Share Posted November 17, 2014 I think I'd avoid headaches and just put in another stack, I don't know of any codes that allow more than one unit on a stack. Wood and coal are two very different fuels to exhaust. I'm no expert though. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
arkie Posted November 17, 2014 Share Posted November 17, 2014 I wonder if you would have the capacity for both? Your shop stove pipe probably was built to handle the volume of smoke from the stove. Adding more from the forge might or might not give you the necessary draw. Then again, the stove's pipe upward draw might pull your forge better...dunno...food for thought. Stove experts out there???

41flathead Posted November 17, 2014 Author Share Posted November 17, 2014 That was my original thought. That the stove draw would benefit. I don't know how I would test it without just doing it. Arkie, I noticed you are from NWA. Where about? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 17, 2014 Share Posted November 17, 2014 Twice the open area should cut the draw by about 1/2.Look at pictures of a side sucker system bending the flames horizontally and explain why it needs the extra help?

Frosty Posted November 18, 2014 Share Posted November 18, 2014 No, the smoke from the stove will fill the stack's carrying capacity. Both will draw worse, not better. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
41flathead Posted November 18, 2014 Author Share Posted November 18, 2014 You make a good point. Haven't really thought of that way. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted November 19, 2014 Share Posted November 19, 2014 A forge is an open hearth, or in other words a type of fireplace. A wood stove is a different kind of heating appliance a fire place draws a lot of air to insure the smoke makes it up the flue, wile the stove, being enclosed draws less air.

Smokin' Coke Forge Posted November 19, 2014 Share Posted November 19, 2014 Are you talking about installing a coal forge? You might want to consider that the chimey on a woodstove works a little different than one for a coal forge. Generally, a woodstove uses a 6"- 8" flue pipe, whereas a coal forge works best with a 10"-12"+ chimney. You'll likely find that the smaller pipe from the woodstove is inadequate for drawing the exhaust from a coal forge. Also, most building/fire codes that I have encountered don't permit sharing a flue pipe between 2 systems. Quote Link to comment Share on other sites More sharing options...
41flathead Posted November 19, 2014 Author Share Posted November 19, 2014 Yes I'm building a coal forge and it is a 6" stove pipe on the wood stove. I am a little concerned about the capacity of the pipe. I live in the country and it's my personal shop I don't think code violation will be an issue.

ThomasPowers Posted November 19, 2014 Share Posted November 19, 2014 Is your building insured? If so and you put in a non-code installation they will probably refuse to pay on it if *anything* happens. I was born in Fedvill, graduated from the UofA and married there; still drive through from time to time...lots of kin folk in NW AR; got a stepdaughter and twin grandkids in West Fork...

Charles R. Stevens Posted November 19, 2014 Share Posted November 19, 2014 Really better if you just back up and build a 12" pipe for your forge, dont plumb in your wood stove as it will still mess things up. You may consider a damper and make up air if you live in cold contry. Make up air is never a bad idea for a woodstove either, better to pull in temperd air from a controled sorce than cold air from anywar it can find a way in.

41flathead Posted November 21, 2014 Author Share Posted November 21, 2014 Thanks guys for all the advice. Thomas if you get back to the area let me know we'll go grab a burger or something. Better yet if I have all this built by then you can come over and show me a thing or two. :) I know I'll need all the help I can get.

41flathead Posted December 8, 2014 Author Share Posted December 8, 2014 Well guys I am very happy to say IT WORKED!!! I cheated just a little but I'm ok with that. I hook up an air line to help create a vacuum. It takes about 3-5 minutes for the flu to get hot and once it does I can shut the air off and it drafts GREAT.
