Anyone tried using Tees instead of elbows for flue piping? A guy mentioned this to me as a tip for easier cleaning. Sounds like a good idea.

No theories please, I only want to hear from people who have actually done this and the results.

Excellent idea. A tee at the back of the boiler will get most of the flyash, and makes for easy service.

Mine is set up this way to make cleaning easier and it works very well.

I have my baro mounted in the end of the T so I can easily inspect the horizontal pipe run to see if it needs cleaning. Not a recommended spot for a baro but it works fine for me. I can slip the vac wand past the baro flapper into the horizontal section of flue pipe when the stoker is idling and clean it out without shutting down, takes less than 30 seconds.

I have good draft on my stove / chimney set up. A T will impede draft more than a 90 will. I forget the # of feet of straight pipe each is equal to but the T is more than the 90. So if you have marginal draft you may want to think twice about doing this.

My manometer is mounted permanently so I am always able to see the draft numbers.

Just remember to make a snug-fitting cap for the bottom of the TEE.Back of the boiler gets my vote for best location.I am going to add one to my system,on an EFM 520.What a difference a clean stack makes,and this is the easiest way to keep it clean.

I use T's. There is one here at this pipe into the chimney and another where the pipe comes out of the boiler before it goes up. Works great and I can clean out fly ash in seconds without shutting down.

Yes, if you look at some of the Stove Pics Thread or the Manometer Install threads, many good pics of setups and many of us use TEE's for clean out.

With a flyash making coal stoker ALWAYS use Tee's instead of 90's.

1) The bottom of every vertical section needs a Tee facing down. You can put a 1 foot piece of pipe on the end with a cap to create a flyash trap. That makes it real easy, pull the trap, empty it in the ashpan, install the trap.

2) The top of every vertical section needs a Tee facing horizontally. Pull the cap off and vacuum out. Quick and easy.

Using 90's only makes life complicated. You have to shut down the stove, and pull the pipes to clean out the flyash. And YES, you will need to clean out the flyash a few times per year.

Yes, I always use "T" as well.
