Operating Information
Turning the heater ON
When you press the ON/OFF button, the LED
display will illuminate, the spark will ignite the
main burner and the combustion fan will begin to
run.
This heater has an automatic ignition system.
When the main burner has lit, the combustion
lamp will glow red, and the spark will stop.
If ignition does not occur after 15 seconds, the
appliance will automatically turn off and fault code
11 will be displayed on the control panel. This
may occur when using the appliance for the first
time or if it has not been used for a while. Try
operating the appliance again.
There may be a smell of burning dust or oil the
first time the heater is lit or when the heater has
been out of operation for a long time.
The appliance may make noises after ignition or
when it is turned off. This is normal and is due to
the thermal expansion or contraction of its
components.
Adjusting the Temperature
The temperature setting and the room
temperature are indicated by the L.E.D. display
on the control panel. When the appliance is
turned on the temperature setting will be
displayed for 10 seconds. The display will then
show the room temperature. The default
temperature setting is 72 F.
To change the temperature setting press one of
the temperature control buttons once. The Set
Temp should light up and the display will show
the current temperature setting. Continue to
press the control buttons until the desired
temperature setting is reached. After 10 seconds
the display will return to showing the room
temperature.
The thermostat automatically modulates the
burner and the fan to maintain the temperature
setting.
The temperature settings available are:
LO - burner is on minimum combustion
60 F - 80 F in two deg ree increments
HI - burner is on maximum combustion
Turning the heater OFF
Press the ON/OFF button. Do not
turn off by unplugging at the power
outlet.
The fan will continue to run for a short time to
prevent the internal components from
overheating.
Economy Mode
Pressing the Economy button will
cause the appliance to go into
Economy Mode and the green lamp
will glow. This results in the
temperature setting being reduced
by 2 F, 30 minutes after the room
temperature has reached the
temperature setting. After another
30 minutes the temperature setting
is reduced another 2 F. This could result in the
temperature setting being reduced by a maximum
of 4 F. The intent of this mode is to save energy.

Care and Maintenance
Filters
Dirty filters reduce the air flow and the appliance’s
ability to produce heat. The filters should be
cleaned frequently during the heating season. If
the filters become blocked the filter indicator lamp
will flash red. Eventually the appliance will turn
off and display fault code 14 on the control panel
display.
To clean the filters, the
appliance should be
OFF and cool. Remove
the filter and clean it
using a soft dry cloth or
vacuum. If the filter is
greasy wash with warm
soapy water, rinse, and
dry completely.
Maintenance
Repairs should be performed by a qualified
service technician. The appliance should be
inspected annually by a qualified service
technician. More frequent cleaning may be
required due to excessive lint from carpeting,
bedding material, etc. It is imperative that control
compartments, burners, and circulating air
passage ways of the appliance be kept clean.
Any screen or guard removed for servicing the
appliance must be replaced prior to operating the
appliance. Clean as follows:
1. Turn heat off. Allow to cool for one hour.
2. Remove the front panel by removing six
screws.
3. Use pressurized air to remove dust from the
main burner, heat exchanger, and fan blades.
4. Use soft dry cloth to wipe cabinet.
Do not use wet cloth or spray cleaners on the
burner.
The flue should be inspected annually for
blockages or damage.
Motors are permanently lubricated and do not
need periodic lubrication. Keep fan and motor
free of dust and dirt by cleaning annually.
Verify proper operation after servicing.
Visual Inspection of Flame
Check that the burner flames are operating
normally. The flame can be seen through the
circular window through the louvers.
When operating normally the burner flame should
appear as long, clear, blue, stable, streaks.
Yellow flames or an orange color is abnormal and
maintenance is required.

Before Making a Service Call
Before making a service call please check the following:
■At Ignition:
Heater does not operate.
Warm air does not flow when the burner
lights.
Smoke or strange smells are produced
on the first trial light up after installation.
Sharp clicking noises at ignition, or when
unit cuts down on the thermostat, or goes
out.
■During Combustion:
Clunking noise when the thermostat
operates.
Unit is not heating room.
Air filter is blocked or the louvers are
blocked or obstructed.
Heater will not re-ignite after overheating.
■When the unit is turned off.
Convection fan continues to run after
turning OFF.
■Other Points:
Steam is discharged from the flue terminal.
Unit cuts off without apparent reason.
Power Failure.
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?
The fan is started automatically after a short delay.
This is to allow the heat exchanger to warm up, helping to avoid cold draughts.
This is caused by grease or oil and dust on the heat exchanger and will stop
after a short time.
This is simply expansion noise from the heat exchanger.
This is the sound of the solenoid gas valves opening and closing.
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?
Was the appliance correctly sized for the space?
Allow heater to cool, clean air filter, operate again.
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.
This is to remove the residual heat from the heat exchanger. The fan will stop
when the heater cools down.
High efficiency appliances tend to discharge water vapor on cold days. This
is normal.
Check whether filters are blocked. Dirty filters will cause the heater to overheat.
Switch OFF, then ON again when power is restored to re-set controls.

Flue Manifold Installation
1. Disassemble the flue manifold
The flue consists of 3 parts:
sleeve
inside connection
outside terminal
Disassemble the flue manifold by first pulling
out the inside connection. To remove the
outer terminal pull and release the two
internal ties and then pull out the outer
terminal.
Clearance to combustibles for the sleeve and
flanges is zero inches.
2. Adjust the sleeve length
Measure wall thickness through previously
drilled 3 1/8 inch (80 mm) hole.
The end of the sleeve should protrude 3/16 -
3/8 inch (5-10 mm) from the outside wall.
The sleeve is threaded for adjustment. Adjust
the sleeve length to wall thickness plus 3/16 -
3/8 inch (5-10 mm).
NOTE: Do not extend beyond the red line.
For other than the S type flue manifold, if a
shorter length is necessary an extension can
be removed. Cut the plastic and remove the
extension.
The flue manifold must exhaust to the outside.
Do not exhaust into other rooms.
The flue is not designed to be positioned under
floors or below the heater.
This appliance can only be used with one of the
five types of Rinnai flue kits. The flue kits and
their dimensions are listed in the Specifications
section.
Refer to the Flue Terminal Clearances section.

3/16 - 3/8 in (5-10 mm)
3. Attach the sleeve
Attach to the inside wall using 3 screws
arranging the flange so that the marking
