SAFETY DEVICES
Spark Safety Device: Automatically shuts unit down when there is an abnormal spark at time
of ignition. Display lamps “LOW”, “60”, and “64” will activate if this
happens.
Flame Failure Device: Activated when burner flame fails, indicator lamp “ON” flashes. If
burner fails to ignite, indicator lamp “60” flashes. 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. Indicator
lamp “68” “ON” and the “FILTER” indicator lamp flash when overheat
switch is activated.
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.
Indicator lamps “68” , “FILTER” and “ON” will flash.

Overcurrent Prevention Device: This is a 3 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.

TEMPERATURES AND SHOULD STAY AWAY TO
AVOID BURNS OR CLOTHING IGNITION.
This gas appliance must not be connected to a
chimney flue serving a separate solid-fuel burning
appliance.
When the appliance is installed directly on carpeting,
tile or other combustible material other than wood
flooring, the appliance shall be installed on a metal or
wood panel extending the full width and depth of the
appliance.
“WARNING” Do not operate appliance with the
panel(s) removed, cracked or broken. Replacement
of the panel(s) should be done by a licensed or

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. Two 1/8" test plugs are provided for testing of manifold differential pressure. See schematic for
location.
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.

water. The time water lasts varies from 10 to 15 hours, so
check the water level occasionally.
Caution:
G The humidifier tray and the surrounding area are hot when the unit is on. To avoid burns, do not add
water to the tray while unit is on.
G Avoid adding water when the room is susceptible to condensation.

PRE-SERVICE CHECK
Before asking for a service call please check the following points.
These points are part of the normal operation of the unit.
I At Ignition:
Heater does not operate.
Is the heater plugged in?
Have the fuses or breaker blown at the switch board?
Is there a power failure?
Is the air filter blocked?
Is anything blocking the outlet for the hot air?
Is the flue blocked?
Warm air does not flow when the burner
lights.
The fan is started automatically after a short delay.
This is to allow the heat exchanger to warm up, helping to avoid cold draughts.
Smoke or strange smells are produced
on the first trial light up after installation.
This is caused by grease or oil and dust on the heat exchanger and will stop
after a short time.
Sharp clicking noises at ignition, or when
unit cuts down on the thermostat, or goes
out.
This is simply expansion noise from the heat exchanger.
I During Combustion:
Clunking noise when the thermostat
operates.
This is the sound of the solenoid gas valves opening and closing.
Unit is not heating room.
Is the air filter blocked?
Is the set temperature high enough?
Is the warm air outlet blocked by anything?
Are the doors and windows of the room closed?
Air filter is blocked or the louvers are
blocked or obstructed.
Allow heater to cool, clean air filter, operate again.
Heater will not re-ignite after overheating.
Even after unit has cooled down the heater does not ignite again. Repair is
necessary.
Contact your local agent or Rinnai for a Service call.
I When the unit is turned off.
Convection fan continues to run after
turning OFF.
This is to remove the residual heat from the heat exchanger, the fan will stop
when the heater cools down.
I Other Points:
Steam is discharged from the flue terminal.
High efficiency appliances tend to discharge water vapor on cold days, this is
normal.
Unit cuts off without apparent reason.
Power Failure.
Check whether filters are blocked, dirty filters will cause the heater of overheat.
Switch OFF, then ON again when power is restored to re-set controls.

I TYPES COMPATIBLE WITH EXTENSION SET
RHFE-431FA
INSTALLING AN EXTENSION KIT
Installing an extension kit requires construction of an air line and the exhaust line. The air line is connected
between the Air Supply Elbow at the rear of the heater and the air inlet port on the Flue pipe.
Similarly, the exhaust line is connected between the joint pipe at the rear of the heater, and the exhaust
port on the Flue pipe.
Caution: Check to see there is no debris inpipe or hose.
I HOW TO INSTALL
MODEL:RHFE-431FA
Example:Using 2 sets of extension set and 1 bent set.
Example:Using 80 inches slide pipe set.

Screw hose joint half of its length onto the air intake hose, then screw another air intake hose into the joint.
The hose can be cut to the required length.
IMPORTANT: The PVC air line is longer than the exhaust line and may need to be cut to size. Be sure,
however, to thoroughly deburr all rough edges.
3. Affixing the air intake hose and exhaust pipe
4. How to use the bent pipe
NOTE: Maintain 1" clearance between exhaust pipe
and combustible materials (0" clearance between
exhaust pipe and non-combustible materials).

・Set the air intake hose and exhaust pipe into the pipe
clamps, screw the clamp onto the wall fixture, and affix
to the wall with screw B.
・The air intake hose and exhaust pipe can also be
screwed onto the wall using the pipe clamp and
the nut.
With the exhaust pipes inserted into the ends, bend
the bent pipe to the angle reguired for installation.
This part is mainly used for curves and for connection
to vent terminal.

I CAUTIONS
1. Maximum extendable length
2. To prevent water condensation
FOR BEST ROOM AIR HUMIDITY, KEEP WATER
IN THE HUMIDIFIER TRAY.
Condensed water
may accumulate
here, and cause a blockage
preventing combustion.
CAUTION
・13 feet, 2 bends
Never allow the exhaust pipe to sag, as condensed
water may accumulate and cause incomplete
combustion.
・The bend where the hose and pipes leave the body is
not counted.
・The air intake hose should run along the exhaust pipe.
3. Condensed water formed by
combustion, will run back to the
unit, and may overflow from the
condensation pan if pipes are
3˚ slope(approximate)
longer then 8 feet. Therefore, pipes
exceeding these lengths should be
made to drain to the outside by
giving their horizontal portions 3˚ or
more downward and outward slope.

4. Wherever the air intake hose and exhaust pipe
run sideways, try to have the exhaust pipe on
top (to prevent the air intake hose from sagging
onto the exhaust pipe).
