Operating Information

Turning the heater ON

When you press the ON/OFF button, the LED display
will illuminate, the combustion fan will begin to run,
and the spark will ignite the main burner.

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 a fault code
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 degree 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.

Adjusting Air Flow Direction

The vertical louvers may be adjusted to move the air
flow more to the right or to the left.

Use a screw driver or similar object to bend each
louver to the desired position.

Do not bend repeatedly (no more than 5 times) or
else the louver will break.

The horizontal louver (which determines the vertical
air flow direction) is fixed and cannot be adjusted.

CAUTION

Do not adjust the air flow

louvers while warm air is
flowing.

Sensible Temperature Control

The sensible temperature control feature allows
comfortable heating which matches the conditions in
the room.

Based on the information collected by the room
temperature thermistor when the heating starts, the
heating capacity is automatically adjusted to achieve
a comfortable heating effect and to reach the
temperature setting quickly.

Adding Water to the Humidifier

Warm air is humidified when it passes over the water
in the tray.

To fill the tray, remove the bottom trim panel below
the louvers by pulling on both sides. Pull the tray out
and fill with water. Push the tray back in and attach
the bottom trim panel. Do not operate the appliance
unless the humidifier tray is installed.

During operation a small amount of condensation is
produced in the flue system and drains into the
humidifier tray.

CAUTION

Do not remove the bottom

trim panel or the humidifier
tray while warm air is
flowing.

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.

NORMAL

ABNORMAL

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.

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 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?

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 a qualified / authorized service provider.

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.

The termination cannot be vertical.

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 screws

sleeve should extend
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
TOP is at the top.

The flange is offset 2 to allow the
condensate drain to the outside.

6. Lock the ties

Pulling hard on the left and right hand ties,

clip the ties over the notches inside the
sleeve. You should be able to pull the ties 2
or 3 notches past the starting point. Cut the
ties, leaving about 3/4 inch (20 mm) past the
notch. Bend the ties back into the sleeve and
parallel to the wall.

7. Insert Inside Connection Assembly

Push the assemble into the terminal tube,
ensuring that the seal is in place on the
inner tube.

Attach the inside connection with 3
screws. The inner connection can still
be turned to install the screws.

4. Install the Terminal

Check that the terminal seal is in place. For

weatherboard walls, add the second seal next
to the terminal seal to compensate for
weather board angle.

From the outside insert the terminal into the

sleeve with the marking TOP at the top.
The left hand side locking tie should be
marked LEFT .

Extension InstallationKit

If necessary, extention 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 (4m) with 2 bends. The bent pipe attached to the
appliance dose not count toward the max limit of 2 bends. The maximum vertical length is 8 feet (2.4m). Any
length (horizontal and vertical) in excess of 8 feet (2.4m) 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 extentions must not be concealed per NFPA 54 and must be accessible allowing inspection and repair.
Decorative covers are available from Rinnai.

Examples

Extension to the left (facing appliance)

Extension to the right (facing appliance)

Extension through the top

INCORRECT
Too many bends (limit is 2)

Extension Kit Installation

CAUTION

Use the pipe stoppers, connectors, clamps, and screws according to these instructions in

order to ensure no leakage of exhaust gases.

Clearances

exhaust pipe to combustibles 1 inch (25.4mm)
exhaust pipe to non-combustibles zero

Clamps

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 line sags it will not
come into contact with the exhaust line.

Installing the Exhaust Line

The exhaust line is connected between the bent pipe
at the rear of the heater and the exhaust port on the
flue manifold.

To connect exhaust pipes with other straight pipes or
bends, fit the male end into the female end. Use pipe
stopper A to clamp the connection.

Use pipe stopper B tp 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.

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.

Push the air intake hose onto the flue manifold and
secure with the plastic cable tie.

Join air intake hoses by screwing the hose joint half of
its length into the air intake hose and then screwing
another air intake hose into the hose joint.

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
lengh. Deburr all rough edges. Do not cut the hose
attached to the appliance.

Support the air intake hose with pipe clamps.

This Warranty does not cover any failures or operating difficulties due to accident, abuse, misuse, alteration,
misapplication, force majeure, improper installation, improper conversion, improper maintenance or service, or
for any other causes other than defects in materials or workmanship. This Warranty does not apply to any

Rinnai is not liable for any special, incidental, indirect or consequential damages that may arise, including
damage to person or property, loss of use, or inconvenience. Some states do not allow the exclusion or
limitation of incidental or consequential damages, so the above limitation may not apply to you.

Limitation on implied warranties

Any implied warranties of merchantability and fitness arising under state law are limited in duration to the period
of coverage provided by this limited Warranty, unless the period provided by state law is less. Some states do
not allow limitations on how long an implied Warranty lasts, so the above limitation may not apply to you.

This Warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
