Aluminum Chimney, wood insert

[Ko3n3k3]

it isn't mortared along it's length. Is insulating the galvanized pipe off limits, not a good idea, or just not preferable? (just trying to get a feel of what i should do)

I got 17" on the sides out to the start of the bench and 31" up to the mantle. Thanks for the specs begreen!

If that pipe is merely a single wall galvanized pipe, its got to go, period.
The only acceptable galvanized is double wall insulated rigid liner piping which has the galvanized outer shell with a S.S. inner shell and insulation in between.

I really doubt that's a galvanized pipe. It looks like an old rigid liner that's been very hot and out in the elements.

its a 6" pipe. i did circumference near the bottom and it was 19.75

2 π r = 19.75
π r = 9.875
r = 3.14

3.14 * 2 = 6.3 outer diameter right?

I'm thinking I can pull the existing stove. wrap the bottom of the pipe in insulation (pipe has smooth outside) and slide the insulation up for the next piece to wrap on the bottom. rinse repeat til its wrapped up. does this sound like its possible or am I crazy?

Also in my floor plan diagram i tried to show that the stove is gonna be back in a nook but i don't think that i communicated it well enough. is there anything i need to be concerned with those benches or just that its back in a ≈ 7' deep x 12' wide nook.

Wouldn't it have been easier to just measure the diameter of the pipe?

I would hire a pro to come and get some eyeballs on this install, find a CSIA ,NCSG, NFI or WETT certified tech to come take a look at it.

Nah I woulda had to go out to the "apple shed" about 200 yds from my house, get the tractor (i don't own a ladder lol), and have my girlfriend raise me up onto the roof to check the diameter. A stove was hooked up on the bottom end so all i could measure was circumference without pulling it out.


I'm going to try to get someone to take a glance at it soon. However, if it is "an old rigid liner" will I be alright to insulate it in place and go from there?

Sorry I keep asking hypotheticals but I just like to know my options before someone with a financial interest tells me I have to do something.

Guy came and said that the liner i have has to go. He also said that I don't need to insulate the new Stainless liner because it is in a masonry/rock fireplace all the way up. Do you guys agree with this or should i always insulate? Any help is appreciated. Thanks

Insulate doesn't hurt. So what did he estimate it would cost to rip out the old liner?

 

[Ko3n3k3]

he told me 800 on the install. I think i'm just gonna do it myself. It seems super straight-forward. Is there something I may be missing? (tricks/tips)

 

[mellow]

Had to reread pg 1, if this thing is only 16 feet I would insulate for sure.

As for tips, get as many of your buddy's to come help you as possible.

Haha yeah. I just got the old stove outta there. and started making a template for the block off plate. rather bummed that nothing is square in this house but I think i can make it work.

This may be a stupid question but how do you get that roxul insulation on top of the block off plate? Can u get it in all the corners and cracks or do you just put it on top of the block off plate as you push it up into position?
