Hey, new to this sight. Im installing a add on wood furnace in my basement for next winter. I'd like to drop in double wall down my existing single width brick chimney, which is in good shape. Any tips and suggestions on installation and supporting the double wall at the bottom would b appreciated. Oh and its about 30 foot tall. Will 6 inch draw good enough or do i need to go with 8 inch? Thanks

The size of the liner depends on the size of the furnace. If its 8" off the furnace, use 8". You wouldn't be installing a double wall chimney inside the brick. You would use a stainless steel liner with insulation wrapped around it.
The furnace has a 6 inch outlet. I didnt no i could use stainless single wall wrapped in insulation. That would definitely b lighter and easyer to install. Any suggestions on supporting it?

Liner systems are designed to be supported with the top plate. The top plate has a hose clamp welded onto a collar that supports the entire weight of the liner.

Single width brick, no clay liner. Actually in decent shape for being used for coal furnace back in the day.
Heres my next question, how good do the flex liners work? R they safe? Ive asked a couple people about em and was told not to use em. Im all about saving money and making installation easyer but i wana b as safe as i can.
Flex liners are in the majority of installs we see here. Do it right with a decent liner and it should last a long time.
pretty much all we use is flex liner but we usually use heavy wall flex not light wall. light wall is usually .005" or .006" thick while heavy flex is .015" or .016" I believe rigid is usually about .02". that being said there are a ton of light wall liners out there that work very well for a long time but no you don't have to shy away from flex liners at all especially in an old chimney that I am sure is not straight you might have problems getting rigid in.
Chimney is straight, would b a breeze dropping in a flex liner. Im gona look into all my options before i buy anything. Will i need to get everything inspected for my insurance company or do u just call em and tell em?
Oh i will, just wondering what ive got to look forward to. I asked my agent about putting a on in my garage, they said they'd probably drop me if i did, unattended fire they call it. So i put one in and didnt tell them. Kinda nervous about having them sniffing around.
Yes, garage stoves are generally against code. Considering you have already voided policy, why bother asking a second time?
Thats true, i no plenty of people that get away with both. I really dont c the difference between one in the garage and loading a wood burner up in the house in the morning before u leave for work, kinda a joke.

It has nothing to do with "unattended". There are a lot more explosive vapor producing things in garages than in dwellings.
They are not getting away with anything. If there's a fire it's the insurance company that will say sorry, no deal, you violated the contract.
Yes, it isn't simply HAVING insurance that's so important... it's having insurance that actually PAYS YOU (when something bad happens) that's important!
Don't think anybody's trying to do that. Just wanna know: if your house catches fire in any way that might be related to the stove in your garage, is your insurance company going to pay out?
And I'm serious in asking, cause I don't know if they will or not. But it seems like they wouldn't have to if they didn't want to. And if they didn't, wouldn't that kind of defeat the point of buying insurance? For myself, if it weren't for fire risk, I don't think I'd carry homeowners at all.
