If I Draw It You Can Build It


Not necessarily out of the question to build, but why. How am I supposed to run a seam joint like that, I guess ill have to use 8" cmu and do beam courses.

Re: If I Draw It You Can Build It


What is the cladding? It would have to be full thickness stone or stucco??

I would approach it by building the main (rough in) section all bonded together and then add the angle out of brick wire tied into everything else.

The beam pockets would be a potential issue here depending on county.

What about the flue being 45 to the fireplace. I guess a twisted smoke chamber?

Re: If I Draw It You Can Build It


Its better than stucco, its thin stone, ledge with no mortar joints.

The chimney doesnt look large enough to do an 8" block, might have to do 6 above the beam pockets.

I would prefer to just run a seam joint with block, pour the cells and do 3 or 4 beam courses.

I got off the phone with UMACO and they assured me their thin stone mortar will stick to this http://www.camosse.com/wp-content/up...O_USeal_1A.pdf , their version of a thoroseal type product.

So thats how ill keep the chimney dry, dry as can be.

With a reasonable lead time,a wire company can fab joint wire to accommodate the angles. I would have them do it with hooks and eyes so you can bond the veneer.

Re: If I Draw It You Can Build It


I'd do block without too much thought, steel would have to be your main tie but it's either that or pour it, or do it entirely out of brick and that would be pretty slow.

It must be a regional thing...you call that a chimney and so does the archi.

Re: If I Draw It You Can Build It


Seems like brick and lots of wall ties might the way to go, or block with a key course every row if possible. 13x13 flue is huge, I have not laid any bigger than 8x12"

Re: If I Draw It You Can Build It


I guess everything is bigger in Texas, hardly anyone builds a little box like that, most are at least 48", and I sell a lot of 60" and 72" cast iron dampers and they use 20x20 or 24x24 flues.

Strange, 13x13 are the smallest flu tiles I have seen other than some decorative tops. Mostly 13x13 & 13x17 are most common.

More outdoor fireplaces, less trees. Our houses are built in the woods!, leaves everywhere. Racoons down the flues on occasion.

How the heck you lay a 20x20 flue? I would have to warm up before I laid that myself.

General rule of thumb is you need 10% of the fireplace opening in the flue size.

36x30" FP = 1080 sq inches
13x13 flue has an 11x11 opening = 121 inches
8x12(13) flue has an opening of 7.25x11 = 80 sq. inches.

You need a flue with a min. of 108 sq. inches.

Even @ 27 1/2 high (10 courses) its 972 sq. in. Lower than that and its hideous.

16 x 20 is the most common for us.... With the occasional 20 x20 or 24 x 24 job to spice things up. Definitely a test of the 'grip strength' when setting those puppies.

Re: If I Draw It You Can Build It


Fireplace size should be based on room size. A small fireplace in a large room looks just as awkward as the converse. Proportion is the key.Also,lets not forget that the corners in square or a rectangular flue cannot be counted in the formula. They are dead air spaces and an oval or circle must be drawn in them to figure the correct size needed.

Re: If I Draw It You Can Build It


It would have to be really close for me to worry about the size of the circle, then I would just go up 1 size most likely.

Re: If I Draw It You Can Build It


13x13 is the most common in my experience for fireplaces, 8x12 for a small fireplace (30") or a chase for a furnace

We mostly use the 8x8 flues here, lots of single flue chimneys here.
