Spark Safety Device: Automatically shuts unit down when there is an abnormal spark at time

of ignition.

Flame Failure Device: Activated when burner flame fails. This prevents raw gas from being

released.

Overheat Switch: This device automatically cuts the gas off if the heater exceeds a

predetermined temperature. This is normally caused by an obstruction in front of the louvers, or a blocked fan filter.

Two Fusible Links: Backs up the overheat switch. If the fusible link cuts the unit off, a

service call by an authorized person is required to replace the link.

– 2 –

Overcurrent Prevention Device: This is a 5 amp. glass fuse found on P.C. board. Design to

shut unit down in case of overcurrent. If fuse blows all indicator lamps will be “OFF”.

Power Outage Safety Device: This safety device cuts off gas passage and stops

operation.

Local and state codes must be adhered to prior to installation.

Rinnai is continually updating and improving products therefore specifications are subject to change without prior notice.

Thank you for purchasing a Rinnai gas forced flue heater.

Before using this product, please read this manual carefully to insure proper use of the product.

Please read the attached warranty thoroughly and keep it in a safe place.

IMPORTANT POINTS / USAGE AND INSTALLATION MUSTS

– 3 –

Unpack heater and check for damage. (DO NOT INSTALL DAMAGED HEATER.) If heater is damaged, contact your supplier for advice. Before installing a heater, check the label for the correct gas type (see label on heater). Refer to local gas authority for confirmation of gas type if you are in doubt.

Included in Carton:

Customers Operating Information

IMPORTANT Before using this product, please read this manual carefully to insure proper use of product.

1. The installation must conform with local codes or, in absence of local codes, the National Fuel Gas Code, ANSI Z223.1 or the Canadian Installation Code, CAN/CGA-B149.

2. For information on gas type, see data plate on the appliance.

3. This heater must not be installed where curtains or other combustible materials could come into contact with it. In some cases curtains may need restraining.

4. This appliance is not designed to be built in.

5. If you move, check the gas type in the area where you are moving to. The local gas authority will be able to advise on local regulations.

6. This heater discharges a large volume of warm air at low level to provide even heat distribution. If the air in the room contains cooking vapor or cigarette smoke, and the heater is used on a carpet, the surface of the carpet may become discolored. In addition, some nylon carpets contain dyes which may be affected by the warm air flow. Some soft vinyl surfaces are also subject to distortion, or discoloration by warm air. To prevent discoloration of carpets, etc., a mat should be placed under the appliance, extending about 30" (750mm) in front of it.

Diagram shows minimum clearances from combustible materials.

Rinnai recommends 10 inches (250mm) clearance on both sides for future servicing.

7. Read these rules and the instructions carefully. Check all local codes. Failure to follow these could cause a malfunction of the heater resulting in death, serious bodily injury and/or property damage.

8. This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases, unless a certified kit is used. If a conversion of the unit is needed, conversions must be performed at Rinnai America or anthorized agent at owner's expense.

9. WARNING: Any change to this heater or its controls can be dangerous.

10. If a gas leak is suspected, turn heater off, turn gas supply valve off at appliance connector valve. Open windows to ventilate area immediately and contact your dealer or gas company.

11. DO NOT PLACE CLOTHING OR FLAMMABLE MATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS AND LIQUIDS, ON OR NEAR THE HEATER.

12. YOUNG CHILDREN SHOULD BE CAREFULLY SUPERVISED WHEN THEY ARE IN THE SAME ROOM WITH THE HEATER.

13. LPG containers must not be installed indoors.

14. Do not use this room heater if any part has been under water. Immediately call a qualified service technician to inspect the room heater and to replace any part of the control system and any gas control which has been under water.

15. Adequate clearances for accessibility for purposes of servicing and proper operation should be provided.

16. Adequate clearances around air openings should be provided.

17. Do not install in areas where curtains, drapes, clothing, or other moving flammables are within 12 inches of this unit.

18. Periodic examination of the venting system is required.

19. The flow of combustion and ventilation air should not be obstructed.

20. A manufactured Home (Mobile Home) installation must conform with the Manufactured Home Construction and Safety Standard, title 24CFR, Part 3280, or, when such a standard is not applicable, the Standard for Manufactured Home Installations, ANSI A225.1 or Standard for Gas Equipped Recreational Vehicles and Mobile Housing, CSA Z240.4.

21. "This appliance must be installed in accordance with the current standard CSA Z240.4 GAS EQUIPPED RECREATIONAL VEHICLES AND MOBILE HOUSING. Cet appareil doit ette installe conformement aux, exigences de la norme Z240.4 en vigeuer de l’ACNOR, Installations de gaz dans les constructions mobiles et vehicules recreatifs."

22. If a blockage occurs at the vent terminal due to snow, ice, leaves, spider webs or other type of obstructions the unit will stop working. The unit will not function until the blockage has been removed. If the unit then fails to operate contact a qualified service agency.

23. For manufactured (mobile) home or residential installation, this unit has been designed and certified to be converted from natural gas to propane or vice-versa. When provisions are being made to convert this unit, a certified conversion kit must be used. You must also readjust manifold gas pressure to specifications indicated in the conversion manual. If in doubt contact Rinnai America for assistance.

24. Clothing or other flammable material should not be placed on or near the appliance.

GAS CONNECTION

1. The gas supply line shall be gas-tight, sized and so installed as to provide a supply of gas sufficient to meet the maximum demand of the heater without loss of pressure.

2. A shut off valve (and appliance connector valve) should be installed in the upstream of the gas line to permit servicing.

3. Flexible pipe and any appliance connector valve used for gas piping shall be types approved by nationally recognized agencies.

4. Any compound used on the threaded joint of the gas piping shall be a type which resists the action of liquefied petroleum gas.

5. Supplied gas pressure must be within the limits shown in the specifications.

6. After completion of gas pipe connections, all joints including the heater must be checked for gas tightness by means of leak detector solution, soap and water, or an equivalent nonflammable solution, as applicable.

CAUTION: Since some leak test solutions, including soap and water, may cause corrosion or stress cracking, the piping shall be rinsed with water after testing, unless it has been determined that the leak test solution is noncorrosive.

7. The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 P.S.I (3.5kPa).

The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psig.

8. One 1/8" test plug is provided for testing of manifold pressure see schematic for location. (On page 43, item # 125) At time of installation installer must supply a 1/8" N.P.T. plugged tapping, accessible for test manometer connection, immediately up stream of the gas supply connection to the appliance.
