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.
