Primary-Secondary Heating Kit for I-Series Boilers (Heat-Only Models), 807000213

Its fine. As advertised , it works, and it took my labor but it got me in and out of the job faster with less layout effort. Sweat/brazing was a little messy looking and stands out against my work. I'm not bragging, I just think it could have been neater. But then maybe it would be more expensive.

This assembly came like it was put together by a child. I am a plumber and this assembly is nowhere near plumb. For the cost of the product and what arrived, it's not worth the headache.

I ❤️ Rinnai products but this was obviously not tested the pulled tee sections leaked in two places normally these are brazed but I am not sure what they are securing these with maybe a machine weld I expected rinnai tags on the valves also no watts

I installed this on my new Heat-only Rinnai boiler, but the heating kit had two minor flaws. First, it was not made squarely and was closer to the wall on the supply side than on the intake side. Second, the port for the pressure gauge was only partially soldered, and I had to remove the joint and re-solder it. I was worried that I would unseat the Tee, but I directed the heat away from the Tee. Even though it wasn't square, it fit like a glove and made the installation fly by.

This kit fit perfectly and minimized installation time.

Since this is already plumbed, it makes installing the boiler much quicker and easier, especially for a replacement boiler. It also has the cleanout valves already installed so you can have your boiler cleaned yearly and there is a pipe for the pressure relief valve and pressure gauge to be installed. And Supply House has a great price for the item as ususal.
