ISAFETY DEVICES I
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.

Overcurrent Prevention Device:
Power Outaqe Safety 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".
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.

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. 10"(250ram)
Diagram shows minimum _/"_ o"
clearances from combustible L._J
materials. 2%
40" (lm)
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 acertifiedkit 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 controlscan be dangerous.
10. if a gas leak issuspected, turn heater off, tum 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.

Check to ensure gas type on rating plate matches gas being supplied to the unit. If not, unit may have
been converted and should be checked to ensure conversion was done properly. If not, unitcould be
damaged due to being overtired.
Refer to localgas authority for confirmation of gas type if in doubt.
Refer to data plate located inside of the front panel.
Check for damage, ifthe unit is damaged contact your supplier or Rinnai.
Do not install a damaged unit before checking with your supplier.
Refer to an approved pipe sizing chart if in doubt about size of gas line.
-14-

GAS CONNECTION I
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 itsappliance 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.SkPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual
shut off valve dudng any pressure testing of the gas supply system at test pressures equal to or less
than 1/2 psig.
One 1/8" test plug isprovided 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.
