Care and Maintenance
Maintenance
Filters
All maintenance and service are to be performed by a
qualified service technician, preferably one who has
attended Rinnai service training classes on the Direct
Vent products.
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 and
the appliance will beep. Eventually the appliance will
turn off and the Temperature Level lamp 14 will light,
indicating a fault code.
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.
AIR FILTERS
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
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.
completely.
2. Remove the front panel by removing two screws.
Visual Inspection
of Flame
3. Use pressurized air to remove dust from the main
burner, heat exchanger, and fan blades.
Check that the burner flames are operating normally.
The flame can be seen through the circular window
through the louvers.
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.
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.
Care of Exterior
Dampen soft cloth with warm water. Wring water out
well and wipe the unit.
Do not use volatile substances such as benzene or
thinners. They cause fading of the paint and
deformation of the resin.
Snow Accumulation
Keep the area around flue terminal free of snow and
ice. The appliance will not function properly if the
intake air or exhaust is impeded by obstructions.
Refer to the Flue Terminal Clearances. The clearance
in Ref. A should be maintained from any snow
accumulation.

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 fuse box / breaker panel?
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 a qualified / authorized service provider.
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.
Power Failure.
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.

Fault Codes
If there is a malfunction the appliance may shut down
as a safety precaution and display a fault code to
assist in diagnosing the problem. The fault code will
flash in the display on the control panel. When making
a service call, this code will assist with diagnosing the
fault.
You may be able to clear the fault code by turning the
heater off and then on again. If the fault code remains
or returns on the next operation, contact Rinnai or your
nearest service agent and arrange for a service call.

Restart Function
If the appliance fails to ignite, the appliance will attempt ignition after 1 hour. The “Ignition Failure” fault code, 11,
will appear during that hour and disappears after a successful ignition. If ignition fails again, then the fault code
will remain and another attempt to ignite will occur in 1 hour. The fault code is not stored in the fault code history.
If the flame is extinguished during forced combustion then the appliance will attempt ignition after 1 hour. The
“Ignition Failure” fault code, 11, will appear during that hour and disappears after a successful ignition. Forced
combustion takes place for about 15 seconds after ignition. After this time, the temperature control logic controls
the combustion.
If the flame is extinguished (burner combustion failure) while the temperature control logic is operating the
appliance, then the appliance will immediately attempt ignition. No fault code will appear.

drilled 3 1/8 inch (80 mm) hole.
Remove extension
if necessary
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 Kit Installation
If necessary, extension kits are available to extend the exhaust line and air intake hose between the manifold and
the appliance. The maximum vent length is 13 feet (4 m) with 2 bends. The bent pipe attached to the appliance
does not count toward the max limit of 2 bends. Any length (horizontal and vertical) in excess of 8 feet (2.4 m)
must be sloped 3° downward toward the flue manifold to allow condensate to drain to the outside. Do not allow
any low points in the exhaust line where condensate will collect.
Vent extensions installed in unconditioned air space must be insulated with high temperature insulation and must
be accessible.
Vent extensions must not be concealed per NFPA 54 and must be accessible allowing inspection and repair.
Decorative covers are available from Rinnai.

Clamps
Exhaust pipe
Both the exhaust line and air intake hose are
supported by clamps which are attached to the wall.
A wall fixture can be used to offset the clamp from the
wall. Use Screw B to attach the wall fixture to the
wall. If the wall fixture is not used then use Screw A
and the nut to attach the clamp to the wall.
The air intake hose should always be underneath the
exhaust line so that in case the air intake hose sags it
will not come into contact with the exhaust line.

Use pipe stopper B to fix the length on the adjustable
exhaust pipes. Do not extend these pipes beyond the
red line.
Do not cut the exhaust pipe. Use the adjustable
pipes if necessary.
To bend the elbow, insert exhaust pipes into both
ends for additional leverage. Bend to desired angle.
Adjust the angle
Do not straighten the bent pipe attached to the
appliance.
Connecting the Air Intake Hose
The air intake hose is connected between the air
connection at the rear of the heater and the air intake
port on the flue manifold.
The lengths of the air intake hose and the exhaust
pipe must be the same in order for the appliance to
operate properly. The hose can be cut to the required
length. Deburr all rough edges. Do not cut the hose
attached to the appliance.
Push the air intake hose onto the flue manifold and
secure with the plastic cable tie.
