How Much Stove Pipe Do I Need?

[Simonkenton]

I explained in another thread that I have a 1999 Waterford, 43,000 BTU that does not draw right. It has never smoked, but, it is very hard to light. Also hard to get up to 500 degrees. Usually runs at 375 to 400. I leave the air control wide open all the time and am burning dry wood.

Oconnor explained to me that the pipe is probably too short.
I have 3 feet of vertical pipe going out of the stove. Then, I have a 90, and 4 feet or so goes horizontal through the wall where there is another 90. I have a wall pass through kit and on the outside is a cleanout rig where I can unscrew the cap and run the brush up to the chimney cap.
Outside I have the double wall insulated stainless steel pipe which goes straight up through the roof.

I wish I could tell you how much vertical pipe I have but I am on the road in the 18 wheeler tonight.
I am going to say, about 14 feet of vertical stainless steel pipe.

How much vertical pipe do I need?

I bought this pipe at Lowes 15 years ago. It has threads, of a sort, you set one joint on the section below and give it about 1/3 of a turn to screw it in.

Is this the standard pipe used today, so that I could just go back to Lowes and buy pipe and it will fit?

Thanks for all the info.

I only have around 14 foot with my little 17 vl and have no problems whatsoever. I'm usually up to 400 within 15-20 minutes and have no problem running 500-550 consistently. How dry is your wood?

Rebel do you have any 90 degree bends in your pipe? Oconnor explained to me that a 90 degree bend means you have to have increased vertical pipe.

First be sure that the horizontal run is pitched uphill toward the chimney by at least 1/4" per ft. More is better, so go for 1/2"/ ft if possible. Each 90 turn is going to reduce the effective height by about 3 ft. so it is down to about 11ft of draw more or less. Based on that assumption I would add 4 ft if possible.

Pitch the horizontal run at least 1/4 inch per foot. Y'all are killing me. I have burned the non EPA compliant stoves for decades and they are not so finicky.

OK I will try to put a pitch on that section of pipe although I am not sure how much wiggle room there is in that wall pass through rig. That run is quite level right now, I am an old carpenter and I like to make things level.

Smoke wants to go uphill. Level is not good in this case and could be at the heart of your problem.
