I will be installing a jotul f100 soon and curious as to what the clearance is to combustibles if I'm using single wall pipe WITH a protected surface? Thank you for any help guys!

Single wall pipe has an 18" clearance to combustibles. Describe what is meant by a protected surface.
I was thinking the clearance would be reduced if i used a protected surface on the wall. (Sheet metal, tile, etc.)
if it is protected with a ventilated shield then yes it would reduce the clearance by 2/3rds which would mean 6" but if it is just tile on the wall you get no reduction
The only way to achieve a clearance reduction is to put shields on the pipe or an NFPA 211 wall shield on the full area behind the pipe. With shielding the clearance can be reduced to 9".

Often a better solution is to go with double-wall pipe which has 6" clearance and the added benefit of a long lasting stainless interior. Double-wall keeps the flue gases hotter for better draft and a cleaner pipe.

Thank you guys, what's the minimum gauge of sheet metal that can be used? I've seen 24,26, and 28. Conflicting..

How many installers would recommend using single wall pipe - vs double. The difference is great, as well as the peace of mind?
We use single wall on most installs unless it is a long run of pipe or there are clearance issues. Then we would go double wall.
Some short runs benefit from double-wall too, especially if the chimney is short or clearances too close.
Yeah we do a case by case evaluation but most times we dont see the need
I have 4' of single wall going on 10 years old. Is there a typical life span of single wall. Thanks in advance for any info. ps , didn't intend to steel the thread.
Depends on the gauge of the pipe, the wood burned, moisture exposure, the temps that the pipe has seen, etc.. Cheap, thin black pipe can be badly deteriorated after a few years. OTOH a good heavy gauge black pipe can be fine in 10-15 yrs given good conditions.

Can I ask what is wrong with snap lock pipe? I'm not trying to argue, simply trying to educate myself.
It's all I've ever used because it is readily available locally. I wouldn't even know where to get "good" pipe lol I'm going on 4 years with snap lock on two different stoves.
I used it for years as well. Never had a problem, other than it rusting through but that was my fault for burning wet wood. Now, I feel more comfortable using butt-welded pipe, where there's virtually no chance of it ever coming apart. It's also heavier gauge as a rule. Right now I'm venting into my fireplace chimney with a stainless tee connected to a heavy-duty stainless flex liner....and I've got dry wood!
