Still trying to figure out how to get this thing open so I can burn wood.

[Ontheroofs]

Any clue how to open this thing? Brick, rock and mortar haven’t been removed to place this block in the flue. It’s exactly 10 feet up from the ground I cant figure out how to get it open. So can’t get to it from outside or inside just this small shaft coming out the front which I assumed was for hanging stuff on but it’s exactly where the flue is blocked in the picture. I’ve put a pipe wrench on it but it doesn’t seem to want to move either way. Any ideas

Is it metal? Is it some sort of butterfly damper that has rusted in place?

So it’s a thick steel chimney? That’s a surprise.

I can’t tell muck from the pictures. Is be trying to spin it around the axis where that rod protrudes. I’d try banging on the rod and seeing if it spins. While a helper taps is it from above.

I was thinking of banging on the plate on either side of the rod. Could squirt some WD40 down on it, but it may stink up the house if it drips down into the fireplace.

Hard to tell what I'm looking at but yeah if it's a damper then that rod should spin 90 degrees.
If it's been closed for a long time, there could be a cake of debris sitting on top of it, impeding its movement.

I have the same type of T handle butterfly damper. Mine used to spin 360 degrees when it was in use. I can easily see how creosote /rust, dirt can jamb it up if it has not been used for a few years or more.

It looks like the metal pin you show was drilled for a T to be inserted in the end. Mine is a welded T. Yes try to spin it. Can u get a screwdriver in that hole to help you spin it?

And as Ebs said if you can tap the edges of the metal damper with a long pole that might help break up the debris.

It's hard to tell from the pics but it almost looks like someone may have sealed it with tar around the edges.
Hopefully not and that is just ash / creosote.

This is mine. It’s about 7 ft high off the floor. Built in the early 40’s I believe. The rectangle butterfly in this one is inside a rectangular terracotta liner.

OP said they put a pipe wrench on it and it didn't move.

Try harder 🤪

I don't see the bite marks of teeth on the jaws of vice grips or a pipe wrench.
I still suggest getting some penetrating oil on the circumference, let it sit for at least a few hours, then bang on the edges away from the center rod (you can faintly see where it is welded up the middle). Then, try the pipe wrench or vice grips to wiggle it free.

 

[bigealta]

Try pulling it too. it almost looks like it could be sitting just a bit above a lip on the top right? Doubtful this is how it works, but u never know.

Update everyone I finally got it free all the times I tried before didn’t work cause I don’t want to tear anything up but we got 22 inches of snow coming allegedly this weekend so it was time to send it. I put and 18” pipe wrench and a 14” and used both arms and a lot of my body weight to get this thing moving but since it broke lose it moved like butter. I know it’s been shut for at least 20 years from the timeline I know on the house. 9 of which I’ve lived here and never burned wood in it. A quarter turn and it’s fully open. Thanks for the help everyone I took the advice and “tried harder” I’ll post more once I get it up and running.

It’s got a hole through the side I assume it had some kind of handle or lever but they took it off for whatever reason.

Yeah it looks like some kind of thick industrial pipe. Cabin was built by a guy that owned a sawmill so a lot of stuff is over built. Curious to see how good it works since I got it open finally

It's probably well casing. Unfortunately, that will conduct heat more to the surrounding chimney and though durable, wouldn't pass modern code.

I would not be surprised if your fireplace smokes into the room.

looking forward to hearing more, now that you got it open.
