EGR 250 side clearances
« on: June 26, 2017, 06:29:35 AM »

Does anybody have any suggestions on the clearances needed to get to the sides of and EGR 250?

I am looking at putting it in a 3 sided building with the open side being the front of the OWB and a wall to the RH side of it. I will be stacking wood to the left side in the same building.

The manual calls for 18" on LH and RH side and 60" for front and back. Seems a little tight on the sides.....

Also is there any problem with adding more exhaust pipe to get out through the roof? How high above the roof would I need to extend it?

Far as the pipe, keep it as short as possible, gasifiers run cool enough on the exhaust that even with double wall insulated pipe condensation and buildup can be a problem. Straight shot if possible, use 30ís if a straight shot isnít possible.

I agree , keep the chimney as short as possible.
Does the EGR250 have anything you need to access on the sides? Cleanouts,  controls, etc.

Is the roof of this building metal or shingle? If it is metal I wouldn't worry about going more than a foot out the roof.  If it is shingle I would go 2 feet.  My shed is 14 foot tall to the peak and I have he chimney exit in the middle of the rear peak at 12 foot.  My stove stands 6 foot at the chimney exit and I have 8 feet of chimney pipe connected to it leaving 2 feel out of the roof.

Metal roof. Planning on making it a single slope. 3 sides of the building closed with one open side. Just to keep the wood dry for the most part.

So I do not need to be taller than the highest point of the roof for the draft to work correctly?

The draft inducer fan on the furnace takes care of the draft. The only reason to get higher is to avoid sweating if the exhaust touches the cold roof.
I've worked in tight places enough that I like to leave at least 36" space all the way around. Mine is outside, woodshed nearby.

Agreed, Iíve wiggled into some places that once there didnít have room to get a welding helmet on, held a piece of 4x6 lens instead. Inside combines are fun, its a real joy wiggling under a grain bin floor for any reason, really fun if you have 30,000 bushels on top of the floor.

Moral of the story, leave yourself plenty of room, youíll appreciate it more as you ah, mature.
