It is hard to provide a quote without seeing the chimney, knowing how tall it is, what size it is, the type of furnace, difficultly of roof access, etc. Price could be 2 to 5 thousand dollars depending on all of the variables.Get 2 or 3 estimates from realiable contractors in your area.

If you are talking putting a gas insert fireplace inside your existing fireplace, then that would be part of the installation job - they run a double-walled stainless duct up the chimney, so the $200 or so installation cost for the exhaust stack is part of the installation cost.

If you are talking about using the existing fireplace chimney as a stack for a true whole-house gas furnace, in most jurisdictions that would be illegal. However, if legal then the metal double-wall stack duct would be run up and centered in the existing chimney flue with metal "spiders' (spacers), if the chimney is straight enough, so usually no additional cost compared to running exhaust stack up through a wood framed house - a bit of brick removal to gain access versus the hassle of running duct up through and fastening it to wood along the way, with required firestops, is about the same amount of work, if doable.

Usually, with modern fan-driven pulse rather than continuous-burn furnaces, rather than run up through a chimney they just direct vent outside the wall.

Hello,

It would be safe to say you can expect to pay $800.00 - $1200.00 for a typical 25' Installation

6" Lifetime Warranty Stainless Steel Liner, Components, And Installation.

Of course there are a number of factor that need to be taken into account, But for the purpose of given you a number without knowing all the details this would certainly be in the area you can expect to pay.


Hope this gives you an ideal, Keep in mind this is without know alot of information.



Great Day,
