4 Rinnai I-Series Condensing Solo Boiler User’s Informaon Manual

Please read and follow the safety precauons listed below.

Environment: Air surrounding the boiler,

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. In applicaons ulizing room

air where there are high levels of

parculates, Rinnai oers a room air

screen. The boiler, venng, and vent

terminaon(s) should not be installed in

any areas where the air may contain

these corrosive compounds.

WARNING

Inspecng the Exhaust and Intake

Venng System:

• Visually inspect the enre exhaust

vent and intake system. Look closely

for blockages, deterioraon, leaks or

any other type of damage to the

system. Repair any joints that show

signs of leakage. Make sure the

intake vent pipe is connected and

properly sealed (if applicable).

• Examine the exhaust vent and air

intake to make sure they are clean

and free of obstrucons.

WARNING

This product can expose you to chemicals

including lead, lead compounds and carbon

disulde which are known to the State of

California to cause cancer, birth defects or

other reproducve harm. For more

informaon, visit

www.P65Warnings.ca.gov.

California law requires the following

Proposion 65 warning to be provided:

Should overheang occur or the gas

supply fail to shut o, do not turn o or

disconnect the electrical supply to the

pump. Instead, shut o the gas supply at

a locaon external to the appliance.

DANGER

Rinnai I-Series Condensing Solo Boiler User’s Informaon Manual 5

• Check the water pressure in the

central heang installaon regularly.

See the “Rinnai I-Series Condensing

Boiler Installaon and Operaon

Manual” for specic glycols,

inhibitors, and system cleaners

permied. Contact your installer in

case of doubt.

• Do not use this boiler if any part has

been under water. Immediately call

a qualied service technician to

inspect the boiler and to replace any

part of the control system and any

gas control which has been under

water.

• Flammable liquids such as cleaning

solvents, aerosols, paint thinners,

adhesives, gasoline and propane

must be handled and stored with

extreme care. These ammable

liquids emit ammable vapors and

when exposed to an ignion source

can result in a re hazard or

explosion. Flammable liquids should

not be used or stored in the vicinity

of this or any other gas appliance.

• Do not obstruct combuson air to

the boiler.

• Do not use an extension cord or

adapter plug with this appliance.

• Any alteraon to the appliance or its

controls can be dangerous and will

void the warranty.

WARNING WARNING

• DO NOT operate the boiler without

the front panel installed. The front

panel should only be removed for

service/maintenance or replacing

internal components.

• BURN HAZARD. Hot exhaust and

vent may cause serious burns. Keep

away from the boiler. Keep small

children and animals away from the

boiler.

• Heang supply and heang return

water pipes leaving the boiler can

be hot to touch.

• Rinnai recommends that every

home have a carbon monoxide (CO)

alarm in the hallway near bedrooms

in each sleeping area. Check

baeries monthly and replace them

annually.

• If using an Indirect Tank for DHW,

always check the water

temperature before entering a

shower or bath.

WARNING: If you do not follow these instructions EXACTLY, a fire or

explosion may result causing property damage, personal injury or loss of life.

A. This appliance does not have a pilot. It is equipped with an ignition device which

automatically lights the burner. Do not try to light the burner by hand.

B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to

the floor because some gas is heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS:

• DO NOT try to light any appliance.

• DO NOT touch any electric switch; DO NOT use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas

supplier’s instructions.

• If you cannot reach your gas supplier, call the fire department.

C. Use only your hand to turn the gas control valve. Never use tools. If the gas control valve

will not turn by hand, don’t try to repair it, call a qualified service technician. Force or

attempted repair may result in a fire or explosion.

D. Do not use this appliance if any part has been under water. Immediately call a qualified

service technician to inspect the appliance and to replace any part of the control system

and any gas control which has been under water.

1. Set the temperature controller to the lowest setting.

2. Turn off all electric power to the appliance if service is to be performed.

3. Turn the manual gas control valve located at gas inlet of appliance clockwise to the

OFF position.

TO TURN OFF GAS TO APPLIANCE

1. STOP! Read the safety information above on this label.

2. Set the temperature controller to lowest setting.

3. Turn off all electric power to the appliance.

4. This appliance does not have a pilot. It is equipped with a direct ignition device which

automatically lights the burner. DO NOT try to light the burner by hand.

5. Turn the manual gas control valve located at gas inlet of appliance clockwise to the

OFF position.

6. Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If

you smell gas, STOP! Follow “B” in the safety information above on this label. If you don’t

smell gas, go to the next step.

7. Turn the manual gas control valve located at gas inlet of appliance counterclockwise

to the ON position.

8. Turn on all electric power to the appliance.

9. Set the temperature controller to desired setting.

10. If the appliance will not operate, follow the instructions “To Turn Off Gas To Appliance”

and call your service technician or gas supplier.
