PHukill Posted October 31, 2017 Share Posted October 31, 2017 I am forging in a 10 by 14 foot metal shed. I am using an old outdoor city park grill for my forge. I need to vent this out doors. There are open doors and holes everywhere, and I live in Michigan, so it's cold. can I just put an 8 inch pipe over the top and vent this out the ceiling? Do I need an exhaust fan too, do I need a ventilation system for a small propane forge? Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted October 31, 2017 Share Posted October 31, 2017 if you read the other posts you will notice a common thread about needing 10 to 12 inch for a coal flue. This is because the smaller pipes dont draw enough. the open doors should be plenty for the gasser Quote Link to comment Share on other sites More sharing options...
JHCC Posted October 31, 2017 Share Posted October 31, 2017 Regarding the propane question, a number of folks have recommended getting a couple of carbon monoxide detectors if you're using a gas forge. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted October 31, 2017 Share Posted October 31, 2017 For a coal forge, you can't beat the super sucker with a 10 inch stack for venting it. Just putting a flue above it will not work even with a hood. BTW: if you edit your profile to show your location you may be surprised how many of the gang live close to you and we won't remember you are in Michigan after leaving this thread.

Daswulf Posted October 31, 2017 Share Posted October 31, 2017 Putting a flue above it with a hood will work if done right. As in proper height from the fire and limiting the amount of shop air entering. some of the other threads also discuss height of the pipe above the roofline and such for getting proper draw.
