F E A T U R E S O F Y O U R N E W WATER HEATER
The Rinnai Water Heater is one of the most advanced water heaters available.
?
It supplies hot water continuously at the temperature preset in the unit or at the
temperature set on the optional remote controller(s). Installation of remote controller(s)
are recommended for optimum performance.
The Rinnai Water Heater never runs out of hot water. While electricity, water and gas
?
supplies are connected, the Rinnai Water Heater produces hot water whenever the hot
tap is open.
The gas burner lights automatically when the hot water tap is opened, and goes out
?
when the tap is closed. Ignition is electronic, there is no pilot light. When the hot water
tap is off, no gas is used. You save energy and money with the Rinnai Water Heater.
The temperature of the outgoing hot water is constantly monitored by a built in sensor. If
?
the temperature of the outgoing water rises to more than 6 degrees above the selected
temperature (shown on the digital remote control) the gas burner will automatically go
out. The gas burner will re-ignite once the outgoing hot water temperature falls below the
selected temperature.
Built into the microprocessor of the Rinnai Water Heaters is the ability to LIMIT THE
?
MAXIMUM TEMPERATURE of the hot water supplied by the Rinnai Water Heaters.
Without the connection of a remote controller(s), the Rinnai Water Heater is preset to
deliver water at 120OF (Residential) and 140OF (Commercial).
Residential Unit: With the remote controller(s) the water temperature is adjustable from
?
98 to 140OF. The water temperature cannot be set to a temperature other than
120OF without the use of a remote controller unit.
Commercial Unit: With the remote controller the water temperature is adjustable up to

Always check water temperature by hand
before entering the shower or bath. The
temperature may have been changed.
The Rinnai Water Heater controls the water
temperature automatically. To do this, it
sometimes needs to change the water ow
accordingly. The water ow from the hot water
tap may vary after the selected temperature at
the remote controller(s) is altered. The water
ow may also vary from summer to winter, as
incoming water temperatures differ.
Depending on the weather conditions and
the length of the pipe between the Rinnai
Water Heater and the tap in use, there may
be a variation between the temperatures
displayed at the remote controller(s) and the
temperature of the water at the tap.
Do not clean remote controller(s) with
solvents. Use a soft damp cloth.

Hot Water Is Dangerous, especially for the young and the elderly or
the inrm. The Rinnai Water Heater allows you to precisely control the
temperature of your hot water, ensuring safe hot water temperatures.
Water Temperatures over 125°F can cause
severe burns instantly or death from scalds.
Hot Water can cause rst degree burns with
exposure for as little as:
3 seconds at 140 °F
20 seconds at 130 °F
8 minutes at 120 °F
Test the temperature of the water with your
elbow before placing a child in the bath or
shower.
Do not leave a child or an inrm person in
the bath unsupervised.

1) Remove clothing; Remove all wet clothing, quickly. Wet clothing retains the heat.
2) Apply cold water for 30 minutes; Immediately submerge the burnt area in cold
water for 30 minutes to reduce the heat in the skin, preventing deeper burning.
Never use butter, oils or ointment to cover the burn. They may retain the heat.
3) Keep the scalded person warm; Place a blanket around the person.
