Proper installation of a Rinnai condensing tankless water heater.

In this video I show a couple of very important install procedures that will make the installation and the unit trouble free.
The unit we installed is a Rinnai RUR98I natural gas unit with a dedicated 3/4″ circulation loop already installed by the contractor when the house was built.
The bypass valve is important if there is no return loop in the house and must be installed. The factory installed plug must be removed and the supplied filter installed in it place.

  1. Mike after doing so much research I had decided to buy TAKAGI brand tank less heater. Then I came across that TAKAGI got sold to the A O SMITH. After TAKAGI got sold , their tech support is not doing well to support their products. So after that I started to do research for the RINNAI and realized that RINNAI has the best tech support and product support with great warranty. Also they are industry leading since long time. Also this is Japanese company so I would prefer better quality with best service and warranty. So I finally bought Rinnai RUC98IN. I tried to educate myself from all videos and article from youtube and internet , Yours is one of the best informative video to the current plumbing ,gas and construction code. You have shown every single small detail very nicely. I am requesting that when you do next time any installation video, please use close body cam like "GO PRO" kind. And also please upload full video so the all details can be seen. I am little advance DIY so I can quickly grasp lots of information while you fast forwarding the video, but still detail video will be great information for newbies.Keep doing great work.Good Luck.
