Am attempting to install a Navien NR210 water heater. Am using the Navien valve kit. Because of new home construction/installation I am very flexable with how to install.
Here is a picture of the current planned plumbing configuration. I figures since the valve kit uses union type connections I wouldn't need another union on the water lines. Because the copper water supply was so close to the bottom of the heater I decided to plumb direct.
Haven't soldered anything yet. Any ideas of suggestions will be greatly appreciated!
