Operating Instructions; How To Set The Temperature; Setting The Sound Volume (Voice Prompt) - Rinnai RV53E Operation And Installation Manual

The RV53i and RV53e models do not come with a temperature controller. There are several models of
temperature controllers that can be purchased separately.
A maintenance display or status monitor is provided in the front panel to indicate operating status and error codes.

How to Set the Temperature

DANGER
1. If the water heater is off, press
the ON/OFF button to turn on.
2. Press the "Priority button" on the
temperature controller. The
green Priority light will glow
indicating that this controller is
controlling the temperature and
that the Rinnai water heater is
ready to supply hot water.
The priority can only be changed
while no hot water is running.
3. Press the ▲ or ▼ buttons to
obtain the desired temperature
setting.
All hot water sources are able to
provide water at this temperature
setting until it is changed again at
this or another temperature
controller.

Operating Instructions

Hot water can be dangerous, especially for infants or children, the elderly,
or infirm. There is hot water scald potential if the thermostat is set too high.
Water temperatures over 125º F (52º C) can cause severe burns or
scalding resulting in death.
Hot water can cause first degree burns with exposure for as little as:
3 seconds at 140º F (60º C)
20 seconds at 130º F (54º C)
8 minutes at 120º F (49º C)
Test the temperature of the water before placing a child in the bath or
shower.
Do not leave a child or an infirm person in the bath unsupervised.

While any hot water is being provided,
NOTICE
the temperature setting can only be
adjusted between 98º F (37º C) and
110º F (43º C).
Check local codes for the maximum
NOTICE
water temperature setting allowed
when used in nursing homes, schools,
day care centers, and all other public
applications.
If a newly installed unit with a
NOTICE
controller has not been powered for at
least 6 hours then the temperature will
return to the default setting of 104º F
(40º C) if power is interrupted.
There may be a variation between the
NOTICE
temperature displayed on the
temperature controller and the
temperature at the tap due to weather
conditions or the length of pipe to the
water heater.
