I renovated the room my stove is in over the summer and decided to move it further away from the wall to eliminate the need for a heat shield. I now have 36" clearance from the stove to the wall. The flue was a straight run out the top of the stove and through the roof. I needed to add 2 elbows to get the 36" clearance for the stove. I realize single wall stove pipe clearance is 18" to combustibles. Stove pipe running through a support box would be within inches of combustibles at the point just before the pipe enters the support box. How exactly do you decipher this info? I know on base burners the flue stays fairly cool. When I restored the stove I never cut the rear flange into the rear pipe, instead I installed a 6" oval to round adaptor and just ran the flue straight out the top of the rear pipe. I'm not sure what to do here. If clearances are an issue I guess one fix would be to install the rear flange on the rear pipe and 90 off the flange into the flue. Then the flue would run straight up and into the support box. It was a pita cutting the flanges into the rear pipe, I'd like to avoid that if possible. Thoughts?

Make two 45 deg bends instead of the two 90's , it will draw better also. If your not burning wood, I wouldnt worry about it.....

Easiest thing to do is put the elbows just above the baro and run straight up from there. Save fancy for next time.

2- 90's=180*
2-45=90*
Easy and pretty comes secondary to function.
Why a baro with the MPD on this suspended fire pot BB ?

Two 45's won't bring the stove out far enough to give me the required 36" clearance. As far as the baro and MPD go, the stove was drafting too hard last season to maintain a decent draft with the MPD closed 100% and the internal check damper open 100%. I needed to add the baro to get the draft down. I guess my set up is the exception to the "no baro with antique bb's" myth.

2 45° will with a piece of straight between them and will be a little less drag on the draft. That said, you have what you need, go with it.

I agree with the 'let it alone'. You aren't going to run it hot enough to cause any problems burning coal and you don't need the extra draft.

So...because of all the wonder stove pipe products on the market none of the pipe fit together when I decided to move the elbows around... ! The only spots the elbows would fit was on the support box or the Chubby adapter on the rear pipe. So I simply put both elbows on the lower section of the flue on a 45 angle and ran the pipe straight up to the support box. The top 12" section of pipe is a slip connection so it makes installing and removing quite easy. This should do the trick! Thanks again for all the ideas.

You are likely thinking of the power vents,those cannot be used with a hand-fed unit.waldo lemieux wrote:I didnt think you were supposed to use a baro with a hand fed??
