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 fl ow from the tap to lessen it, you may have gone below
the minimum fl ow required. The Rinnai Water Heater requires a minimum
fl ow rate to operate (see specifi cation page for fl ow 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 fl ow below the
desired minimum fl ow rate. Decrease the temperature supplied by the Rinnai
Water Heater at the remote control or increase your total fl ow.
Q
- White smoke comes out of the exhaust!
A
- During colder weather when the exhaust temperature is hotter than the air,
the exhaust fumes condense producing white steam.
Q
- When I open a hot tap. I do not immediately get hot water!
A
- Hot water must travel through your plumbing from the Rinnai Water Heater to
the faucet. The time period for hot water to reach your fi xture is determined
by the amount of water in your plumbing system between your water heater
and the fi xture, water pressure, fl ow rate of fi xture in use, etc.
Q
- After I turn off the hot water tap, the fan on the Rinnai Water Heaters
continues to run!
A
- The fan is designed to be on for 65 seconds after the fl ow of water stops.
This is to ensure constant water temperatures during rapid starting and
stopping, as well as exhausting any residual gas fl ue products from the unit.
