Determining if current gas line is sufficient to run Tankless Water Heater
Hi, I intend to install a Rennai Tankless Water Heater on the outside of my house. There is an existing gas outlet at the location that was probably put there to run a barbecue. It is a 3/4 inch line. How do I determine if the outlet has sufficient flow to run the water heater? Is there test/device I can use?
The heater requires 199,000 BTU
