I’ve got a half-finished house with a brick veneer and want to add a brick chimney for a wood stove to the exterior wall of the house. Can anyone suggest the best way to anchor the chimney to the existing brick veneer? I envision expanding metal masonry anchors in the wall, with bolt heads or studs protruding into the joints of the chimney brick. Should the chimney also be anchored to the wall framing somehow? There is no drywall yet, so I have complete accessibility. Of course, the chimney would be built on a substantial footing. Any ideas greatly appreciated!

Rich, I would get some 5/16" threaded "ready rod" in lengths long enough to go down each side of your chimney and into the house through a hole drilled in the existing brick mortar. The rod would be bent to just curl around the far outside of the new chimney, be buried in the mortar down each side of the chimney and then go into the house and be attached to wood framing in the house. Put these rods about every 2'. It does not take much to hold a chimney like this in place, PROVIDED you have a very good reinforced footing sitting on undisturbed or well compacted ground.

You might want to fake the brick chimney too (like the brick house). I didn't realize that even wood fireplaces could use metal chimneys ... build a "chimney" around one of these for appearances. A lot of older houses around here have a chimney settling in one direction, the house in another ... maybe just an old house problem ...
Actually, is this feasible? A client wants a wood fireplace, but I shudder at the cost for the chimney -- or the looks of the big metal flues her neighbors have.

Andrew-
Thanks for your input. Of course the easiest approach would be to just install an insulated metal flue that penetrates the roof (If you've ever priced them, you know that's not a cheap route either), with no brick. Personally, I think exposed metal flues are more appropriate for 'Deliverance'-type properties where they are complemented by old tires, junked school buses, etc. I'm pretty sure that a true masonry chimney will far outlast a metal one, whether the latter is encased in brick or not, so I think I'll be building a real masonry chimney.

but I LIKE rusty cars on concrete blocks etc. It is probably the truely American architectural style.
The metal flues are bloody ugly.
