Temporary Chimney, anyone ever constructed one?

I had to erect a“temporary” chimney. It consist of 8’ of single wall pipe out of the house(through a 100% masonry wall), continuing on a 45 degree angle upwards for 10’,then make a 45 degree turn straight up for 12’, all will be 6” dia pipe. I constructed it really solid, and the stove pipe is well anchored and is NOT in contact w/ any wood materials.
I’mconcerned that I may have draft issues due to a single wall pipe in the cold, shouldI insulate the exterior piping, or not? Has anyone done anything like this before? Any info is appreciated. So far with not very cold temps & temp swings it is working well. I also have installed a cap since the pic was taken.

Many thanks,,
Bob in Rosedale, MD.

How much separation do you have from combustibles? To be honest, your installation looks like an accident waiting to happen. I dare you to send a picture of it to your homeowners insurance agent (or claims department), asking for their blessings on the installation.

Some of your deck or house trim members could ignite from a hot fire making the stove pipe close to red-hot, even though there might not be direct contact. Under certain ambient conditions, I've seen wood and painted sheetrock smolder when several inches away from hot steel. Your pipe terminus also appears to be too close to the nearby combustible roof--I believe the requirement is 2' above anything within 10', and yours looks considerably less than that (based on visual scaling from the railing post spacing, assumed at 6' +/-).

Beyond Bridgeman's comments, which are spot on, when do you plan on installing the permanent one? What are your plans for a permanent one? Temporary as it may seem it is a fire hazard. Set too close to combustibles, and no cap as a spark arrestor,

Draft aside, in cold weather this set up will be a creosote generator.
OK if you want some cheap wood preservative but you would need to place a pail under where ever it drips.

I am a true diy'er but I'll echo the comments about your insurance company.
Most policies require that wood burning equipment be listed and that they conform to local codes.
Be aware that your insurance policy is likely void and would be even for an unrelated fire.

I am sure you would be happy burning wood and the sooner you dismantle all that pipe and put in the real thing the better.....not worth gambling on what looks to be a nice house IMO.
