Re: How to minimize smoke on Facade

Here is another problem oven and a fix.

I think the pictures on this one demonstate the problem quite well. The fix is not as nice but it seemed to work.

Re: How to minimize smoke on Facade

I have the flue sitting on 2 half bricks at either end of the landing so the opening into the flue is smaller than the flue itself.

I think this may be the problem. My oven, 2 fires, seems to be doing well. I am going to add another 12 inches to the height and drop the decorative brick down one inch on the front arch - someone else mentioned that and it seemed to solve the problem. My flue is 8 x 19; here are a few pics to show you the depth. Hope this helps.

Re: How to minimize smoke on Facade

I think a cast or metal vent instead of the typical arch is the best way to keep smoke off the facade.

My cast vent broke when I removed it from the form, but it makes a nice cutaway view. Smoke exiting the mouth of the oven does not really have any chance to roll out the front. I feel this is often overlooked when current builders use the arch design. Note that I put a fake arch on the front of the oven to keep the arch look...

Re: How to minimize smoke on Facade

If I could do it all over, I would copy Drake's vent. Looks like it should draw extremely well - can't imagine any smoke escaping the entry. At the time, I was unsure of using a castable and didn't want any potential "do overs".
Yet another idea I will "steal" if I ever build another. In fact, I may copy the entire design...I love the brick/stone look.

Re: How to minimize smoke on Facade

Drake, very nice oven facade. Those pieces on the outside framing the entrance, are they precast stuff? What about the sill? Where do you get those? Also, I cannot tell do you have an inner lip to close the door up against?

Thx

Re: How to minimize smoke on Facade

Those parts are all precast GRFC (Glass reinforced fiber concrete). I purchased them from a guy here in Denver Architectural Accents - Fireplace mantels, fireplace surrounds, columns, medallions, crown molding.

If you think about ordering some precast stuff, make sure you stetch out the actual dimensions, since most of these pieces are made to go on houses, many of them are huge!

The sill is a fireplace mantle that came in three pieces and we cut it down (we being me and the masons, I built the oven and framed it, but masons put the decorative stone on...it had to look good you know?)

I do not have an inner lip to close the door up against, but I would add that if I did it again. I do a lot of baking and my door (before I burned it up, but that is another story) rests against the bottom of the vent.
