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.
The temperature setting and the room
temperature are indicated by the L.E.D. display
on the control panel. When the appliance is

CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
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:
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.
AIR FILTERS
1. Turn heat off. Allow to cool for one hour.
Visual Inspection of Flame
2. Remove the front panel by removing six
screws.
Check that the burner flames are operating
normally. The flame can be seen through the
circular window through the louvers.
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.
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.
NORMAL
Flame Rod
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.
Long, clear, blue,
stable flames
Care of Exterior
Dampen soft cloth with warm water. Wring water
out well and wipe the unit.

Before Making a Service Call
Before making a service call please check the following:
■ 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.
■ 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?
Was the appliance correctly sized for the space?
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.
■ 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.
■ 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.
Check whether filters are blocked. Dirty filters will cause the heater to overheat.
Power Failure.
Switch OFF, then ON again when power is restored to re-set controls.
