    Looks good, looks good.

    Only thing I suggest, is:
    http://www.caleffi.us/caleffi/en_US/....jsp/index.sdo

    It doesn't actually matter, but when you go to change out that expansion tank, you'll thank yourself that you can isolate the tank from the system.

    If something like that is expensive, hard to get, whatever, a ball valve works just the same. You just use less fittings with the caleffi valve.

    I see 2 pipes sticking up on the right, coming off the bottom of the boiler.

    I assume thats for an indirect? If so, cool stuff.

    Combi Boiler the two pipes are for Domestic hot water. These boilers are really nice and do a great job keeping up with both heat and hot water at the same time. Can't wait put mine in.

    Need neutralizer on condensate. Also better to pipe feed into navien provision for it on the right side. Automatically shuts off feed if boiler feeds for more than 7 minutes. Technically don't need the pressure reducing valve but we use them too.

    We usually dump condensate thru neutralizer and then into pump and send it away.

    I'd also look into the webstone ISO kits or the navien manifold makes piping and servicing them way simpler.

    I've used the the navien header beside, not really a fan of it plus it didn't really fit this application.

    Looks good. We installed this brand for the first time a couple weeks ago. Installed as instant hot water heaters. I was impressed with how smooth everything went. Converting to LP was easy, and it was nice to not have to spend a bunch on costly venting pipe. Do you know if they have seperate units that would do just boiler or just instant hot water, or is it all in one? The ones we put in had the circulation pump built in also. I just was on the install, not the ordering, and wasn't sure.

    As of right now there is combi boiler and solo water heaters. They are releasing a boiler only this year.

    We haven't had good luck with the electronics. Mainly the pressure switches.

    It's a condensing boiler. What vent should he use?

    Interesting. Never installed one, that's why I asked thanks.
