Trouble Shooting for Common Issues

I don,t have any hot water when I open the tap.

Make sure there is gas, water, and electricity to the Rinnai water heater (power is turned on and the gas is turned on)

When I was using the hot water, the water got cold.

If you adjusted the flow from the tap to lessen it, you may have gone below the minimum flow required. The Rinnai Water Heater Requires a minimum flow rate to operate. (See the specification page for the flow rate of your model.) Decrease the temperature setting at the remote controller or increase the water flow.

White smoke comes out of the exhaust.

During colder weather when the exhaust temperature is much hotter than the outside air, the exhaust fumes condense producing water vapor.

When I open a hot tap, I do not immediately get hot water.

Hot water must travel through your plumbing from the Rinnai water heater to the faucet. The time period for hot water to reach your fixture is determined by the amount of water in the plumbing system between the water heater and the fixture, water pressure, and the flow rate of the fixture.

After I turn off the hot water tap, the fan on the Rinnai water heater continues to run.

The fan is designed to continue running for a short time after the flow of water stops. This is to ensure constant water temperatures during rapid starting and stopping, as well as exhausting any residual gas flue products from the unit.
