I have City Gas (outdoors) and have a gas line going to my outdoor Generac generator. Will this unit hook up to the gas line?

6.4 GPM Liquid Propane Gas Mid Efficiency Outdoor Tankless Gas Water Heater is rated 4.3 out of 5 by 12.
Rated 5 out of 5 by from Best way to have hot water. Take it out of box and hang it on the wall. It is propane gas, so hook your gas line , didn`t have to have a bigger gas line, used the one from the old 40 gallon gas hot water heater. Hooked the water line. Hook up electric wire and you are ready to have hot water. I can already tell I haven`t used much propane with this heater. My brother and I installed this tankless hot water heater. (I was the gofer). He has a tankless water heater in his house.

Rated 5 out of 5 by from Best customer service ever The best part of purchasing this product was the help that I received from Andres at the store on US1 and 32nd Ave. He found exactly what I needed and wrote up the order. It was interesting that while he was writing up the order a man came into the store specifically to thank Andres for the help he had given him with some gardening issues. Obviously this young man is a real asset to your store.

Rated 4 out of 5 by from Great product, TERRIBLE customer service :( Great product, we have several of these in our cabins. Fairly easy to install if you have electrical / plumbing skills. These work great, hold up to our cold winters here in NW NC.
