TROUBLE SHOOTING AND COMMON QUESTIONS
Q
- I don't have any hot water when I open the tap!
A
- Make sure there is gas, water and electricity to the Rinnai Water Heater
(the power is turned on and the gas is turned on)
Q
- When I was using the hot water, the water got cold!
A
- 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
specification page for flow rate of your unit). If you mix the water with a tap and attempt
to get a temperature well below the temperature being controlled by the unit, it may drop
the flow below the desired minimum flow rate. Decrease the temperature supplied by the
Rinnai Water Heater at the remote control or increase your total flow.
