    With a couple days off work it seem like a good time to get serious about installing my boiler. I took advantage of Thanksgiving day guests to drop in a new flue liner and then spent quite a bit of time in the basement since. I'm waiting for a zone valve, should have been in by Friday, that I'll use for the low temp return. Other than that, I'm ready to shut down the system and tie in.

    Looks great, r. Really professional looking job. I love working with the black iron.

    I know you're going to be thrilled with it. Those things toss out some heat.

    For me its more a case of I hate working with copper. Also I think with threaded pipe its easier to make changes.

    Thanks, Rob.

    Looks great! I'm looking forward to a 'first heat' report.

    Thanks for posting pictures of your setup. It sure helps me as I try to figure out how best to hook my EKO up.

    No new photos, but I was up till about 2:30 last night tying the new piping into the existing. I have a few more things to do, but I'm hoping to maybe start a fire this weekend.

    Don, I'm glad to have something useful to offer. I'm pretty new to this, but I've learned a lot from many helpful people here. If this is of any value, I had an earlier post "boiler controls" that sort of describes what I'm trying to do.

    I had a few leaks on my black iron connections, all of which disappeared after a few heating cycles. I don't know what your experience with black iron is, Rob, but don't be alarmed if you get a few drips right off the bat.

    One comment...

    With the common wet-rotor circulators, the shaft should always be horizontal. In the first pic, at the far left, there is a circulator with the "can" under the pipe. While you're working on the system, unbolt that, and tighten each flange a 1/4-turn, so that the pump can be installed with the shaft horizontal. Most premature circulator failures are due to improper installation.

    Looks like you're having fun with black iron, though!

    Eric, I did a fair amount with black pipe last year. When I replaced the oil boiler I also replaced the copper monoflo piping. The monoflo left some rooms cooler and I didn't really see a good way of correcting this so I repiped it all with black and put a balancing valve on the return from each room to control flow. I think I've seen this refered to as a direct return system.

    The only place I really had problems with leaks was with the unions. I started using a thick liquid type dope and they were good. Last night when I pressured up I didn't find any leaks, Praise the Lord.

    I thought the only unacceptable mount was with the can vertical. However I checked taco's manual and you are absolutely right. Thanks for catching that.

    WE HAVE LIFT OFF!

    First fire about 6:30 last night. One of the first things I did was turn the thermostats up. What a nice feeling. I have some bugs to work out with how I'm controlling the system. When I got up this morning, I had a no fuel alarm even though there was still a good supply of wood inside. I called home ealier and the alarm had tripped again.

    Is the fun just beginning?

    Been refining mine for more than two years now, and I still have a good-sized list of improvements to make:

    1) Turbulators for my heat exchanger tubes in the EKO (Thanks, Eric! I needed more stuff to do.)
    2) EKO fan override - I want to turn it off earlier when the fire has died.
    3) Radiant main floor zone.
    4) 'Next fire' calculator function
    5) More hx surface area in tank for DHW preheat

    and on and on and on. At least each of these improves quality of life.
