How To Set The Temperature - Rinnai VC Series Installation And Operation Manual

How to Set the Temperature
This water heater requires a minimum flow rate to operate. This rate can be found on the specifica on page in
this manual. In some cases when you are not ge ng hot water or if the water alternates between hot and cold,
it is due to the water flow being below or close to the minimum flow rate. Increasing the flow rate should
resolve these problems in these cases.
If you are experiencing issues with higher temperature se ngs, then reduce the temperature se ng. Selec ng a
temperature closer to that which is actually used at the faucet will increase the amount of hot water being
delivered to the faucet, due to less cold water mixing at the fixture.
