  1. you need to have 3/4 gas line feeding the unit up to 20 feet of piping you may be starving the system for gas and it is shutting down we had one doing this and it drove us nuts. good luck

Don't install multi-sensor computer-chip water heater to water lines and gas line and vent pipe since tankless will develop unsolvable problems.
Contact Rinnai and hear them tell you to call service technician, only to discover there are no qualified service technicians in your area who might be able to solve problem. 1-800-621-9419
Ask why the Rainnai site has much promotional information and no service manuals. Nor does Rinnai offer forum where tankless owners can freely exchange their endless unsolvable problems for all to see.

What does it take to convert a Rinnai R75LS water heater from propane to natural gas?


Contact Rinnai.
Gas control valve is different, burner is different, burner and gas valve must match, threads are regular instead of reverse, dip switches probably have to be changed since combustion of NG is not as hot. Maybe different sensors. Pressures are lower with NG.

Rinnai R50LS- water doesn't heat, even though there is good flow.


If it's a new install: the water is going backwards through the heater and you need to check that your cold water IN is actually hooked up to the cold water IN spot on the heater. they don't register flow if the flow goes backwards through the heater.
If it's not a new install: something is stuck in your flow sensor, drain the unit and take it out to check.

Rinnai Tankless won't stay on


how far is the tankless from the gas meter? error code 12 means it doesn't have enough gas running to it. is the 3/4 flex true 3/4 or is it 1/2 with 3/4 threads. have you checked your BTU load on your house to make sure your 1'' pipe can handle everything else you have on the house? sounds like to me you dont have the right amount of gas to the unit.
