Tankless Unit Gas Connector


Recommended Posts


Unless your local code prohibits flex connectors I would see no problem IF the proper length and BTU output of the connector met or exceeded the demands of the hot water heater and complied with the tankless manufacturer install docs. Remember, these things consume A LOT OF GAS (100,00 to 250,00 BTUs/hr) under full demand and you must account for this.

FWIW, rigid pipe is always better in my mind.
