must be used for hot water pipes below 36” due to

burn risk to children.

Safety Behaviors and Pracces for the Consumer and Installer

 Before operang, smell all around the appliance

area for gas. Be sure to smell next to the oor

because some gas is heavier than air and will sele

on the oor.

 Keep the area around the appliance clear and free

from combusble materials, gasoline, and other

ammable vapors and liquids.

 Combusble construcon refers to adjacent walls

and ceiling and should not be confused with

combusble or ammable products and materials.

Combusble and/or ammable products and

materials should never be stored in the vicinity of

this or any gas appliance.

 Always check the water temperature before

entering a shower or bath.

 To protect yourself from harm, before performing

maintenance:

 Turn o the electrical power supply by

unplugging the power cord or by turning o the

electricity at the circuit breaker. (The

temperature controller does not control the

electrical power.)

 Turn o the gas at the manual gas valve, usually

located immediately below the water heater.

 Turn o the incoming water supply. This can be

done at the isolaon valve immediately below

the water heater or by turning o the water

supply to the building.

WARNING

 Use only your hand to push in or turn the gas

control knob. Never use tools. If the knob will not

push in or turn by hand, do not try to repair it; call a

Consideraon of care for your water heater should

include evaluaon of water quality.

The water must be potable, free of corrosive chemicals,

sand, dirt, or other contaminates. It is up to the

installer to ensure the water does not contain corrosive

chemicals, or elements that can aect or damage the

heat exchanger. Water that contains chemicals

exceeding the levels below aect and damage the heat

exchanger. Replacement of the heat exchanger due to

water quality damage is not covered by the warranty.

Determine Installaon Locaon

Environment

Air surrounding the water heater, venng, and vent

terminaon(s) is used for combuson and must be free

of any compounds that cause corrosion of internal

components. These include corrosive compounds that

are found in aerosol sprays, detergents, bleaches,

cleaning solvents, oil based paints/ varnishes, and

refrigerants. The air in beauty shops, dry cleaning

stores, photo processing labs, and storage areas for pool

supplies oen contains these compounds. Therefore it

is recommended that outdoor models be used for these

locaons where possible.

The water heater, venng, and vent terminaon(s)

should not be installed in any areas where the air may

contain these corrosive compounds. If it is necessary for

a water heater to be located in areas that may contain

corrosive compounds, the following instrucons are

strongly recommended.

IMPORTANT CONSIDERATIONS FOR:

Indoor/Internal Water Heaters

 DO NOT Install in areas where air for combuson

might be contaminated with chemicals.

 Before installaon, consider where air has the

ability to travel within the building to the water

heater.

 Where possible, install the water heater in a sealed

closet so that it is protected from the potenal of

contaminated indoor air.

 Chemicals that are corrosive in nature should not

be stored or used near the water heater.

Outdoor/External Water Heaters and Vent

Terminaons of Indoor/Internal Water Heaters

 Install the water heater as far away as possible

from exhaust vent hoods.

 Install as far away as possible from any air inlet

vents. Corrosive fumes may be released through

these vents when air is not being brought in

through them.

 Chemicals that are corrosive in nature should not

be stored or used near the water heater or vent

terminaon.

Damage and repair due to corrosive compounds in the

air is not covered by warranty.

Water Quality

* Source: Part 143 Naonal Secondary Drinking Water Regulaons

If you install this water heater in an area that is known

to have hard water or that causes scale build up the -

water must be treated and may require more frequent

heat exchanger ushing schedule.

When scale build-up in the heat exchanger begins to

aect the performance of the water heater, a diagnosc

code “LC#” will display. Flush the heat exchanger to

prevent damage to it. Scale build up is caused by hard

water and can be accelerated if the unit is set at a high

temperature.

Rinnai oers Southeastern Filtraon’s “ScaleCuer

Water Condioning System” that oers superior lime

scale prevenon and corrosion control by feeding a

blend of control compounds into the cold water supply.

You must ensure that clearances will be met and that

the vent length will be within required limits. Consider

the installaon environment, water quality, and need

for freeze protecon. Requirements for the gas line,

water lines, electrical connecon, and condensate

disposal can be found in their respecve installaon

secons of this manual.
