Just built my first stove. Couldn't get it to draft properly with a vertical feed tube so I capped it at the base and have gone horizontal for now.
Now I'm onto the exhaust. What is the consensus on a direct line from the exhaust port to the outside stove pipe? My other option is a 90° and a short rise before a second 90° to a wall thimble and THEN to the outside stove pipe.
I need to get this installed this week- input is desperately needed
From your other post, you built a 4" J-tube RMH. This would be considered an advanced project, and has to be done exactly right to work well (or at all). It would also have a small output at best, only suitable for warming one room. What is your layout like: room size, connecting spaces, total house, chimney height above floor level, your climate...?
Asking about connecting to a chimney sounds like you don't have any such connection yet. If that is the case, it's no wonder you had issues. A 4" system would probably be incapable of functioning without a good chimney to add draft. Do you have any mass around the exhaust yet? Can you measure the temperature of your exhaust directly after the RMH barrel, and at the location of your chimney connection?
What is the length from the barrel to the chimney connection? A 4" system would have a short maximum run, and two 90s would further decrease the length it can handle.
