-.01 is a little low for over fire draft. Lowering flue draft would lower it even further, right. I'd leave it as is or maybe lower combustion air slightly to get closer to -.015 per the manual. You seem to check on it at least daily so you're probably OK at -.01, but it will drop fast once your PV starts ashing up.

Finally had some cold, well colder weather....low 20's with a strong NNW wind. Absolutely no propane fire cycles and boiler is keeping up on it's own!
Good to hear this!

Larry, do you think I would benefit to changing the flue draft to .04 from .05?

I don't see where that would make a difference...draft at breech is what it is weather it's being pulled from a chimney or power vent correct? The baro sets the breech draft and my theory is -.04 is a slower draft than -.05 but I don't know how much? Also not sure if it would affect the over fire draft it I went down to -.04. Guess I'll have to experiment.

Finally had some cold, well colder weather....low 20's with a strong NNW wind. Absolutely no propane fire cycles and boiler is keeping up on it's own! One thing that confuses me is I installed a foam board cover for the refractory cover and it's still 90* in the boiler room? I thought for sure that cover was radiating all that heat but could it be coming from the 1 1/2" pipes? ANyway was good to finally check settings under a heavy load and I have the fire settings as close to perfect as I have ever had them. Full grate of fire and my draft almost to factory spec...... .01 over fire and .05 at breech. If I went to .04 at breech would that slow down the draft just a fuzz to get more heat absorption in the water?

And it will never be the same as a chimney! A good chimney gets cleaned once a year even if it doesn't need cleaned.

Performance of a PV degrades minute by minute, day by day. :)

True statement! I feel it is in my best interest to have a chimney built. I need to get a chimney quote so I will know for sure how much I need to save and set a fund aside... it is an inconvenience cleaning for sure.

Here is a pic of where it would have to go. I have the first overhang from the new addition and then the massive overhang at the peak of the gable end. How would you do it? Remove the siding from that side of the house and block up attaching to house every so many feet and just cut the overhangs and flash around? I would just want to make sure it would last. And how do you come out of the basement to attach, just a triple walled piece above ground to tie into the base of the chimney?

Yes to the siding and overhangs.

You need to dig down and put a good size footer in, a lot of weight in a chimney, and then you put the flue through the concrete wall under grade.

So would you put the flue in the footer or dig really deep and start the block say 3' below grade and put the flue in that? How would you clan that, by taking the flue apart from the inside? Seems like a lot of dust would settle there.

You should go down below frost, put a pad in as a footer, then just start stacking your blocks. The bottom block gets the clean out, this is usually at floor grade inside or a little higher, then just stack your block and flue up as you go, and put the round flue in through the wall where you need it to go, as high as possible I advise.
