Newest Rinnai Install

Just finished it this week.

Not as pretty as some of yours.

Pretty good looking to me.
I see the pump inside the unit and one at the manifold.
But what is the story with the pump flanges bolted together on the lower right?

Looks good, your solder joins are much better than mine, these ole hands are kinda shaky so my joins embarassingly look like they were done with a butter knife.

Looks good to me.

Good eye. I'd forgotten that the boiler already comes with a pump and had installed a 15-58 there.

One thing I'm starting to do is to put hose bibbs at the x-tank to make it easier to drain and check tank pressure. The last one I checked that didn't have a drain took 30 minutes to slowly drop the pressure because I didn't want the water to go everywhere. Doesn't Webstone have something for this?

Pressure relief valves should be installed vertically. Technically the pressure relief valve should be above the heat exchanger but I believe only one state adheres to this part of the code. I also recommend the relief valve's discharge pipe ends around 6 inches from the floor with the end made that is cannot easily be capped or plugged.
Nice work.

What model Rinnai is this unit?
I see Rinnai just came out with a i series combi boiler that will do heating and domestic hot water at the same time.
The two smaller models deliver 4.1 GPM domestic hot water
The larger model delivers 5.1 GPM domestic hot water
All three at a 70 F temp rise.
Looks like a interesting combi boiler.

Looks good. Webstone does makes an expansion tank isolation valve that works really nice in most cases. Reasoably priced as well

Thanks for all your comments. I value them!

Bob: This is an e50c and I believe the i series will take the place of the e series.

wes: Beautiful work. Thanks for the Webstone lead.

Keith: The relief lines in the photo terminate outside the shed and daylight about 6" above grade. Code is 6" - 24" above grade and I don't believe we have those other restrictions on relief valve placement out here. You would have to disfigure the copper at the termination to prevent it from being capped, no? Good to know what others do in other parts of the country.
