What is the proper way to seal liner to stove?

[herdbull]

So I've seen a few different ways that people do this. Some use cement, sealant, metal tape, other aeronautical tape.... so what is the proper way to get a draft free permanent seal?

I'm looking at relocating the blower on the 30 so it accessible for maintenance when this season is done. The liner will have to be loosened/raised to do this. So when I reconnect it what is the proper way to do this?

Also for those of us with a tight fitting liner that doesn't easily move up and down why don't they have some sort of slip joint at the stove that would make removal easier. This will be a small battle all in it's self to get the liner to raise 2"-3" to remove the stove.

I'm also thinking of an offset box but have yet to see one that is draft free or air tight. Any recommendations? Any reason these need to be stainless? I'm almost thinking a guy could weld one up out of steel if he could get his hands on some 6" round collars. Wouldn't be that hard to do?

There is really no real reason to use sealant on the stove connection. If you are using the proper adapter, it's a tight fit. It's just like stove pipe, no sealant is used on stove pipe. If smoke leaks from a joint, then that is a indication of a draft problem.

They don't make a slip piece for liners because the liner doesn't typically go into a stove that needs to be removed. They either are hooked to an insert, or there is a tee. But with a top exit stove, you don't have much choice. Is it pushed back into a fireplace?

I see, I guess my vision of a tight fit is different than most stove designers. Unless it's a press fit there's room for air to be sucked into it and up the liner. I dunno, just thinking out loud there. No smoke leaking, I just want to seal everything up as best I can. I guess you wouldn't run a stove with a leaky door gasket, why wouldn't you want everything sealed up tight?

The stove is pulled out as far as it can be before the liner touches the inside of the steel firebox. It has a step in it that is deeper into the firebox that is actually in the way. It could be pulled out more with an offset box. Maybe upwards of 4". Not earth shattering but it would put the stove 4" farther out into the room. Which is the whole idea. A tee would not be beneficial in this installation.

I used a stainless steel fixed elbow with mine. A bead of furnace cement in the flue collar and inside the end the liner clamps into. When I have to move it forward for blower maintenance I will disconnect the liner from the elbow to pull it up.

Most use furnace cement to seal any gap between the stove outlet and liner.

I wish I had enough room for the elbow but I don't . The elbow would at best gain me an inch, probably even less. I just don't have that kind of room between the top of the stove and the bottom of the steel box. As it is an offset box would be tight. Still think a guy could weld one up. I may try that if i can wrestle up the steel.

Where I got my liner they will make anything, adapters you want to your specs. If you want more info I will have to look back where I got it. (Online)

Are you using the legs or the pedestal? With the ped it is three inches shorter than with the legs. There are also six inch legs available, what I used. The ones that come with the stove are nine inch.

Edit: Never mind. I see in another thread that you have already whacked inches off the legs.

yeah I took a few inches off of them before install. I've got some inches to play with above the stove but not a whole lot. It's suppose to be almost 40 next weekend maybe I'll let it go out and cool down so I can take some measurements.

thanks tfdchief. I might be interested if I can't fab something up myself.
