Flue Stretcher Question

pcs2011 · Aug 6, 2011

Getting a new Jotul Oslo F500 stove next week. Since I had less than 14 feet from the stove outlet to the top of the flue, I decided to invest in a stainless Flue Stretcher to avoid possible draft problems..

I removed the small chimney cap and installed the new stretcher which will add about two feet.

After installation I got to thinking about whether the 8" stainless flue pipe should have been extended also. Should I extended the existing 8" pipe to near the top of the new stretcher?

Any help greatly appreciated !!

Here are photos of the existing cap, cap off, new stretcher on:

You could just add another section of stainless rigid liner with a cap. It would probably work better IMO.

I've never seen a flue stretcher. You'd be better off adding a section of the 8" stainless pipe. Better draft because it's smaller diameter and insulated.

The guy with the bucket of steam has flue stretchers. They are in the locker with the relative bearing grease.

I thought they were in the sea chest? Better go ask the Captain for the keys.

Sounds like a couple of destroyer-types here. Has anybody spotted any b1rds?

Were it me, I would add the pipe and also stuff that thing with insulation. Two feet of cold stainless steel before the flue gases get to the great outdoors is a recipe for creosote and a plugged cap. Right at the time you don't even want to be climbing up on a snow covered roof.

Exactly. It's no good unless it's insulated. It could even create more of a draft problem by cooling the flue gas so fast it becomes an air jam.

My vote would be to give your stove a try as the chimney is and see how it goes before adding anymore pipe.

Good luck,
Bill

Thanks for your response BrotherBart. I think you have the best suggestion. I am going to add the additional length of pipe and insulate it.
I don't want to find out later that I'm having draft problems and then have to fix it. I'd rather start with the recommended flue length and eliminate one of the variables..

Thanks again,
Pete
