Stack height on gasser
« on: July 05, 2014, 10:25:21 AM »
I just finished roofing my OWB/woodshed and was wondering if requirements for the distance above the roof/ridge were similar to a fireplace (2' above ridge within 10') or something else.  I put a metalbestos T off the boiler and installed the factory supplied 3' section of pipe.  This puts me 26" above the shed roof but I'm only 5'6" away from my garage roof.  The reason for the T was to install a barometric damper since I was adding more then the 3' pipe.  And for Slim's peace of mind, I will be installing a couple of pieces of Metal roofing above the boiler.  HaHa.  In all seriousness that is a good idea always.

Its 5' feet here for wood burning. Now that you changed draft, you should measure and make sure it meets manufacturer specs. You can find a manometer for around a$100

That's the beauty of the barometric damper, it can be adjusted!
