I’ve seen a handful of some very nice exhaust systems for outside wood burners that bring the smoke coming out the door outside through a wall or ceiling for the people like me who’s wood burner doesn’t have an exhaust set up on it. Is there a place to buy one or where do you get the parts? I like the ones that have the long skinny opening that mounts above the door!

I have a buddy who hooked up a leaf blower in a homemade shroud. Worked pretty darn good.

When I still had a wood furnace in the basement I just installed a bathroom vent fan in a joist bay directly above the door, 2’ spacing on the floor joists though so it caught a little more than 16” would.

I was pondering this in my head. I can pick up a small electric one for under 60 bucks that I could convert into 4” ductwork. I would just need to figure out how to make the piece over the door

That’s a good idea. I was looking at a vented and lighted under cabinet exhaust fan for 125 dollars from broan but I would have no where to mount it

I tried the 6" inline fans from Menards in a homemade hood. I had 3 or 4 of them and they lasted anywhere from 2 to 6 days each. Apparently the smoke pulls too hard and burns the motor out, I don't think it was a heat issue. Now I just smoke up the shed lol
-
Some 2x4s pieces to make a break. A cheap rivet gun and rivets and some metal tape make what ever you want with some aluminum roll flashing. That how I do my custom duct work around the house/shop. It is not quite as professional as the sheet metal guy but hundreds cheaper.

Thanks I will do that. Going to make a vent hood tomorrow

Here is my vent fan above my G200. Works absolutely awesome and I have about $25 into it.

One more picture from the front.

Heyyyy that looks really good schoppy! Looks like I have a new project to add to the list :photo:
-
Wait, why the hood schoppy, that stove has a smoke bypass on it that always worked very well for me, do you for some reason need a hood?
-
You're right Slim it does have the bypass but when I had the G400 and now the G200 I have always had smoke still come out the loading door. No where near the amount I had when I had my P&M boiler but it is still there. My unit is in an enclosed building so any smoke stays in the building and this vent hood works great at keeping it smoke free. Wife threatened me with physical harm so I had to solve the problem.
I will say the smoke when loading is mainly when I have a fair amount of wood left over from the previous filling and as the left over wood starts to burn off the accumulated carbon and creosote. If it is just coals left then almost no smoke comes out the loading door.
I had an Amish shop that does sheet metal work bend up the metal from plans I drew up. The fan is a circulating fan (all metal) from a junked out mobile home furnace and an 8 inch air duct to get it outside. Made a pendulum damper at the end of the duct that swings open when the blower comes on.
I replaced the door seal this summer and am drip free now. Started my G200 soonest ever this year, mid November, due to a good cold snap then. Love the endless hot water again with the breaker off to my electric hot water heater.
